Solar industry responds to latest cuts to tariffs Despite cuts to the Feed-in Tariff not being as drastic as previous proposals, there are still fears that the diminished incentive will lead to a reduction in demand and further job losses for the solar industry.

The Department of Energy and Climate Change has announced that the domestic Feed-in Tariff will be reduced by 64%, from 12p/kWh to 4.39p. The new tariffs will come into force from 8 February, and the deadline for projects to receive the current higher tariffs is 15 January.

Although this represents a significant reduction in the financial incentive available to UK homeowners, it compares favourably with previous proposals that had suggested cuts of up to 87% to 1.63p/kWh. The decision comes after a prolonged campaign by the Solar Trade Association (STA) and other organisations including the Church of England to the CBI, but the STA estimates that up to 18,700 jobs in the solar industry could still be lost as a result of the reduction.

“It’s not what we needed, but it’s better than the original proposals,” says Paul Barwell, CEO of the STA. “We will continue to push for a better deal for what will inevitably be a more consolidated industry with fewer companies.

“In a world that has just committed to strengthened climate action in Paris and which sees solar as the future, the UK Government needs to get behind the British solar industry. Allocating only around 1% of its clean power budget to new solar is too little, particularly when solar is now so cost-effective. Poor ambition for solar risks missing out on not only our renewable energy targets in the UK, but on the world’s greatest economic opportunity too.”

As well as the tariff rates, the STA has expressed concerns about the ‘cost control’ mechanism that could lead to damaging stopstarts in the market. The Government has put maximum caps on the total amount of solar it wants to see installed in every quarter. The STA argues that this could be very damaging, but it has welcomed the fact that there is no increase in the energy efficiency requirements to be eligible for the Feed-in Tariff nor any changes to the export tariff when electricity is sold back to the grid.

“The new tariff levels are challenging, but solar power will still remain a great investment for forward-thinking homeowners who want to protect themselves from volatile energy prices and do their bit to reduce global carbon emissions," says Barwell. “Solar is still worth considering if you consider the wider benefits such as the increased value to homes. Homeowners can also benefit by changing the way they use their generated electricity or via storage, which is now a rapidly developing market.”

Research reveals cost of DIY disasters New research has revealed that UK homeowners are spending an additional £42million a year to salvage work around the home that they’ve tried to do themselves or abandoned mid-way through.

A survey undertaken on behalf of the Federation of Master Builders (FMB) shows that more than a quarter of homeowners admit they have started and then abandoned home improvement jobs, with almost one third (30%) calling in a tradesperson to finish or rescue the job, costing an additional £871 on average than it would have cost if they’d hired professionals at the start.

Some 27% of respondents admitted that they have ‘given up’ on a job ever being completed –

with 19 months identified as the average length of time before a job is abandoned. One in five said that their attempts at home improvement projects have been ‘disastrous’, with 62% of these admitting that DIY building blunders have reduced the value of their property, and a further 18% believing their properties are now harder to sell.

The two biggest disaster areas for the country's aspiring plumbers came from attempts to self-install a kitchen or a bathroom.

When looking at the main reasons homeowners have dragged their heels at calling in a professional, 55% say they are worried about the cost, while 30% claim they haven’t had time to organise the work. An

indecisive one in five can’t decide or agree on what they want, while 17% haven’t been able to find someone to do the work.

Brian Berry, Chief Executive of the FMB, comments: “While it’s noble that people want to have a go at home improvement projects themselves, our research confirms that if you don’t know what you’re doing, you’re risking not just increased costs, but also your property value – not to mention your health and safety when it comes to serious builds and renovations. Unfinished work and botched DIY attempts are increasingly cited as reasons people turn to our members, so we urge homeowners to be realistic about what they are capable of doing.”

Partnership speeds on JG Speedfit has announced that it will continue to sponsor the GBmoto Kawasaki team in its bid to challenge for the 2016 MCE British Superbike Championship.

The team managed to finish third in last year's championship, winning two races and taking seven additional podium finishes, but aims to go even better this time around. Looking forward to remaining with GBmoto for a second term, Mike Riseley, UK Director of Sales at JG Speedfit, says: "It has been a very successful partnership for both parties and I'm confident that the JG Speedfit Kawasaki team will continue to go from strength to strength."

to consider LPG Viewpoint Installers operating in rural areas are being urged by Calor to start the New Year with a fresh start and expand their service offering to include LPG services. According to the fuel supplier, statistics indicate the LPG market is expanding rapidly, with an annual growth rate of 3.8% forecast until 2018 , so there has never been a better time to consider undertaking LPG training.

The company says it will support installers at every stage of an LPG conversion, and also offers a £250 incentive for each new bulk tank customer they refer, or £100 for a new cylinder customer referral.

National Sales Manager Alastair Lovell says: “Regular training to broaden skills means that installers can offer a wider range of services when it comes to rural home heating solutions, and be able to discuss and advise on the options available in a more knowledgeable manner.

“In order to gain a competitive advantage, installers are advised to keep up to date with advances in systems and technology, as they evolve so rapidly.”

Qualifications available to installers include ‘CCLP1 –

by Chris Jones

If only it was quite that easy

Core LPG Safety Training & Assessment’ and ‘CONGLP1 (PD) – Conversion of Natural Gas to LPG’. The CCLP1 course is a Gas Safety qualification and is required for any gas engineer wishing to work on LPG installations.

The CoNGLP1 course is a ‘fuel changeover’ assessment that allows gas engineers who currently hold a CCN1 (natural gas) qualification to work with LPG domestic installations and appliances.

The assessment covers the fuel characteristics that are different between LPG and natural gas.

Installers interested in learning more about how working with Calor can benefit their business and customers should visit www. calor.co.uk/installer or call 0345 600 7701 for more information.

Those who tuned in to the recent final of the BBC’s ‘The Apprentice’ programme would have seen a plumber from Peterborough become Lord Sugar’s latest business partner.

In what some critics saw as a triumph of an old-fashioned service industry over new-age technology, Joseph Valente’s plans to promote his ‘Prime Time Plumbers’ business was deemed to be a more bankable investment than his fellow finalist’s dating app venture. Being handed a £250,000 cheque from a celebrity entrepreneur is not a bad first step to fulfilling Joseph’s millionaire ambitions, but some viewers must have been left scratching their heads as to what more he had to offer over any other local plumbing and heating business.

As the two finalists were tasked with polishing their last pitches to win the big money, Joseph was persuaded to abandon thoughts of focusing on the promotion of renewables in favour of a business based on reliable service and smart controls. Sound familiar?

Fearful of a future visit from Watchdog, the man with the cheque book offered the helpful insight that a successful plumbing business would be as reliant on the quality of its operatives as the man at the top, but viewers were left to wonder about Mr Valente’s own training or qualifications. Having been expelled from school at 14 with limited future prospects, few would deny our budding entrepreneur a shot at the big time, but it’s a shame if the programme left the impression that fortunes could be made in the plumbing industry with a bit of ambition, a willingness to work hard and a rough idea of where to point the spanner. It’s a good start, of course, but we all know there’s just a little bit more to it than that.

Many installers take pride in the work that they do and now they’re being encouraged to take pride in the van that they drive. UK boiler manufacturer Worcester has launched a monthly competition to showcase the best vans on the road. Installers are invited to take to social media and show off their vans or those of their colleagues.

A weekly winner will be selected to take home a coveted Worcester jacket, then at the end of the month all four motors will be put forward to a public vote for the title of ‘Van of the Month’ and the prize of Worcester’s smart internet-connected control, the Wave. To enter installers simply have to take a picture of their van – or a colleague’s – and Tweet it using the hashtag #Vanofthemonth.

Heating engineers Good times for oil heating customers could be life savers A lifesaving heating engineer from HomeServe has inspired a roll out of basic life support skills for the company’s directly employed engineers.

Leicestershire based HomeServe engineer and former volunteer lifeguard Mike Harrison put his previous life saving training to good use earlier this year when he saved a 90-year-old lady’s life whilst on a routine repair call.

Mike’s story has inspired a company-wide drive to develop a programme of ‘Heart Start’ with the help of the British Heart Foundation (BHF).

Every uniformed engineer in the company has now received the BHF-accredited training programme, which focuses on a range of life support skills including CPR, dealing with unconscious, choking or bleeding people and identifying the symptoms of cardiac arrest or stroke.

HomeServe CEO Martin Bennett comments: “Mike’s story inspired us to provide

HomeServe engineers Mike Harrison and Nathan Moore with Safety Officer Alex Down

our engineers with basic life saving skills. Our engineers meet many people and support vulnerable and older people too.

“We hope these are skills they never have to use.

However, this is something inspired by our engineers and driven by them, so if the training helps just one person, then it’s been the right investment for our company.”

Latest industry figures show oil prices have fallen a further 10.5%. According to the Sutherland Tables, an independent source of data on comparative UK domestic heating prices, the cost of heating an average three bedroom home with oil is now just £793 per year, which is estimated to be 24% less expensive than mains gas. Oil is also claimed to be 48.7% cheaper than LPG and 50% cheaper than electric storage heaters to heat the same average home.

OFTEC Director General Jeremy Hawksley comments: “Oil consumers have seen the cost of heating their homes fall consistently for the past two years and with prices

predicted to remain low for some time to come, the case for sticking with oil, or even switching to oil, is strong.”

With this in mind, OFTEC continues to urge government to completely rethink the UK’s low carbon heat strategy.

at around 30-33p per litre, whereas 18 months ago the cost of a litre could be as high as 55p. This saving has been instrumental in helping the market increase year to date oil boiler sales by 8-10%.

“If ever the owners of older oil-fired boilers needed a reason to upgrade their heating systems, then they have a pretty compelling one at present. Oil certainly offers a considerable opportunity to installers which extends beyond servicing current systems and fitting new boilers, as when oil systems are changed it is not unusual to see a new tank put in as well, all of which contributes to the buoyancy of the market.”

It’s a family affair Record sales from home improvement

Gledhill moves on Gledhill, the family-owned hot water storage business, has accepted an offer of an undisclosed sum from Groupe Atlantic, another family owned company based in France, with manufacturing plants in Europe and Asia. It’s not the first time that Atlantic has taken over a UK heating business, with other recent acquisitions including Ideal Boilers and Hamworthy.

“We are concerned to see DECC is continuing to back the domestic Renewable Heat Incentive (RHI) which has fallen way short of expectations,” says Hawksley. “A far more effective way of reducing the UK’s carbon footprint would be to introduce a simple boiler scrappage scheme, incentivising the replacement of the 600,000 standard efficiency oil boilers still in use with modern condensing versions.”

The fall in oil prices has also been welcomed by Martyn Bridges, Director of Marketing and Technical Support at Worcester. He comments: “The fall in oil prices is a significant one.

Today, the price of oil sits

Sittingbourne-based Swale Heating has built its reputation on being family-friendly – in more ways than one. The company’s staff currently includes four fathers and their sons, and four sets of brothers. There’s also one family that’s been working there for three generations. Call-out engineer Kevin Long (pictured second left) is one of four members of his family who work for Swale, alongside his father, Dean Long (left) and siblings Charley Long (right) and Steven West (second right). Kevin’s grandfather Brian Steddy (centre) was the first in the family to join the company more than 40 years ago. Swale Heating was established in 1972 and now has a workforce of more than 450 operating throughout London, the South East, East Anglia and the Midlands.

Reporting a record six month’s trading, Pimlico Plumbers has cited public confidence in the home improvement market as the key factor in achieving sales of £13.5 million. The company says it has seen a significant increase in largerscale home improvement projects including kitchen and bathroom fittings and building extensions.

To maintain its continued growth, the company, which currently employs 205 trades people and a support team of around 95, is continuing to recruit engineers through its nationwide recruitment campaign with an ambition to take on up to 50 new engineers in the New Year.

Founder and MD Charlie Mullins says: “Traditionally things don’t really take off in the plumbing world until December, but after setting monthly company sales records each month from June to July, we set a company record in September, which was smashed a few weeks later when we hit £2.63 million in November.

“Forget all the surveys, the economic data, reasons for this and that based on interest rates. What I’m seeing is real people, employing real skilled trades to improve and add to their homes and businesses in a way that suggests people are still feeling good about the future.”

Putting the focus on value for money Life Award looking for new entrants

‘Value for money’ is the theme of Ravenheat’s latest marketing campaign as the boiler company asks installers to focus on value as well as price when making purchasing decisions. At the heart of the campaign is the message that Ravenheat boilers offer premium quality at a lower than average price.

Louis Pickersgill, MD of Ravenheat, says: “We are confident that this new marketing campaign will help installers understand

Louis Pickersgill, Ravenheat

that they really can get true value for money by making

the switch to a Ravenheat gas boiler. It is not just about price, although the saving is nice to have – it is also about quality, efficiency, performance, service and warranty. Understanding that Ravenheat boilers offer affordable quality will help installers make the switch from their usual brand.”

Ravenheat says that its CS and WH ranges incorporate features normally associated with higher priced models, including low energ y

consumption, easy-to-use touch controls, large visible temperature adjustment, and brass and premium branded components. Whilst the CS models come with a two year warranty, the WH combi models offer seven years.

“More Installers are opening their eyes to the new opportunities that we present, as it makes upgrading to high efficiency boilers even more attractive and encourages replacement and not repair,” adds Louis.

Specially designed for Channel Islands Marking the launch of its specially adapted boiler for the Channel Islands, Hamworthy Heating recently held the unveiling in St Helier, Jersey.

Contractors and installers from across the region, as well as Jersey Gas, the partners on this venture, came for the unveiling. As part of the event Hamworthy gave a seminar on best practice refurbishment

of heating systems.

Stuart Turner, National Sales Manager, says: “The Purewell VariHeat cast iron boiler has been in production for over 10 years, but in 2015 we have been working hard to adapt the product so that it is suitable for use with LPG Air. We have been working closely with Jersey Gas to test the boiler for safe operation and get it ready for market.”

Training and certification organisation BPEC has launched its search for next year’s recipients of the Life Award, Support Fund and Sport Award.

The Life Award offers grants of up to £15,000 to projects that use plumbing knowledge and skills to improve the lives of others in the UK and abroad and, where possible, to transfer the skills and knowledge to others in the process.

The closing date for Life Award applications is 30 June 2016.

The Support Fund is designed to raise the plumbing skills levels of disadvantaged groups or individuals. The fund can also support worthwhile charitable related projects that use plumbing skills for the benefit of the local community.

The Sport Award encourages sporting excellence across the industry, whether that’s helping individuals or teams reach the next level, pass on their skills to others or compete at regional, national or international events.

New research by the Bathroom Manufacturers Association (BMA) has prompted Bristan to call on the industry to take an active role in spreading the water efficiency message. BMA analysed 23 million households in England and found that 44% still have toilets with a 7.5 litre (or more) flush. It also found that 10 million homes use twice the amount of water they need.

The research highlighted that simply replacing water-guzzling toilets with more efficient models could save at least 644 million litres of water per day in England alone.

Peter Manning from Bristan says: “We ask all plumbers to encourage water-saving to their customers and recommend the most effective water efficient products available.

That way, they can help to raise the standards of water efficiency in the UK while benefiting from a new and growing revenue stream.”

It is with regret and great sadness that Johnson & Starley announces the death of former Sales Director David Gane. He passed away at the age of 80 on the 31st of October following a heart condition.

Colleagues at Johnson & Starley say that David was a charismatic person who had vast experience and knowledge of the heating industry spanning over some considerable years. He joined Johnson & Starley in the early 1980s when he headed up the sales team, and retired in 2000 after making a major contribution to the success of the company.

Awards evening for Lab earns UKAS accreditation Modena outstanding work is back

Mark Haddow (centre) receives award from SNIPEF President John Leonard (r) and BPEC Chief Executive Paul Johnston (l)

LW Haddow of Perth has been named Business of the Year by SNIPEF in the inaugural year of this award.

The installation and service firm was recognised for technical skills and ability, excellent customer service and a commitment to raising standards in the industry.

Mark Haddow, MD of LW Haddow, comments: “SNIPEF accreditation ensures that our customers can be confident of a high level of service. This award means a great deal, acknowledging the commitment, skill and professionalism of everyone in our team.”

Also announced was the winner of the SNIPEF Merchant Customer Care Award. Michael Fraser of William Wilson Ltd, Inverness, was described as

‘extremely efficient, flexible and approachable…whose aim is to make sure we get what we want on time, without any hassle’.

The SNIPEF Merit Award 2015 for outstanding contribution to the plumbing industry was presented to David Osborne who invented a simple device, the Jompy, based on the laws of conductivity to decontaminate water.

In presenting the award SNIPEF Chief Executive Robert Burgon described the device as “already recognised internationally, the Jompy has the potential of changing lives” and said that Mr Osborne “has a vision to help the millions of people in our world who do not enjoy the benefits of basic water supply.”

The United Kingdom Accreditation Ser vice (UKAS) has accredited Adey Professional Heating Solutions’ R&D facility in Kent for testing central heating system water and water treatment products.

The award follows the lab’s BuildCert approval to test products for the Chemical Inhibitor Approval Scheme (CIAS), which was granted in 2014 after just six months of operation.

Mo Jassal, Adey’s Chemical Technical Manager, says: “As the only lab in our industry

to be UKAS accredited, it underpins our technical competence and integrity of both our water testing service and inhibitor performance testing which

LPG crackdown The trade body for the UK’s liquefied petroleum gas industry, UKLPG, has welcomed a successful gas cylinder theft prosecution following a string of arrests made by the British Transport Police (BTP) in December 2014.

The prosecution is said to reinforce the consequences of mishandling cylinders, from both a legal and safety standpoint.

The defendant in the case pled guilty to theft, dangerous transportation and dangerous shipping and started an eight month prison term for attempting to transport more than 400 empty gas cylinders

from the UK to Ghana.

“The outcome of this case is significant, as it shows that the law enforcement agencies and LPG industry are serious about prosecuting people who steal or misuse gas cylinders,” says Rob Shuttleworth, Chief Executive of UKLPG. “The risk of damage, injury or explosion when cylinders are not handled appropriately should not be ignored, and this case shows that there are real consequences for breaking the law. Gas cylinders are designed for reuse upon return and remain the property of the gas company throughout.”

benefits heating system quality. This sets us apart, giving confidence to our customers that we are leading the way in raising quality standards.”

Boiler manufacturer Ferroli has announced that production is back to full strength following a restructure of the company.

The new investors are Oxy Capital Italia, based in Milan, and UK-based company Attestor Capital.

After a pause while negotiations were conducted, production restarted in September and the Modena HE range of combi and system boilers is now back on merchants’ shelves.

Raising funds for sanitation projects In celebration of the UN World Toilet Day, employees at sanitary equipment manufacture Wirquin threw wet sponges at their bosses in aid of ending the global sanitation crisis. The event, held in November, raised over £300 in addition to the £2000 the company has already raised through cake sales, fancy dress days, bike rides and other events.

All of the money raised will support the World Toilet Organisation to fund sanitation projects in Cambodian floating villages. The ultimate goal is to give the adults and children access to safe, clean and private sanitation which will help to prevent disease and death.

Kitting the team

An unusual water sport has attracted the sponsorship of plumbing solutions manufacturer Pegler Yorkshire. Underwater Hockey, also known as Octopush, was developed as a way to keep scuba divers fit during winter months, and Pegler’s own Technical Training Support Manager, Glenn Schofield, is one of the coaches in the UK. “Sponsorship is of paramount importance to allow our teams to enter national and international competitions and develop their skills and confidence as individuals and as a team,” comments Glenn. “Our thanks go to Pegler Yorkshire for its support, and we look forward to delivering great results.”

Pegler Yorkshire has provided sponsorship for out-of-water kit for the U19’s and U23’s ladies’ and mens’ teams.

Report questions combi efficiency A new report by the consultants at Sustainable Homes suggests that the efficiency of combination boilers has been overplayed following a study of gas usage in 500 homes. But are these conclusions taking in the whole picture? PHAM News reports.

C

ombination boilers may not be producing the expected energy savings according to a new study assessing home energy use. Sustainability consultancy and training provider, Sustainable Homes, conducted the study in 500 homes and found that energy use for those with combi boilers was 13% more than homes with hot water cylinders.

According to the report, ‘SAP in the real world: how people use energy in the home’, combis are not always the better option for smaller households that use hot water intermittently and at irregular times. It is suggested that some homes might be better off with a hot water cylinder tank, which have become much more efficient in recent years with the development of high performance lagging that reduces heat loss.

Authors of the report also say the way people use their combi boiler means that potential savings are

often lost. They identified cycling (when exhaust gasses need to be purged) as one of the factors affecting efficiency.

Andrew Eagles, MD of Sustainable Homes, says: “Whilst on a technical measure combis always outperform cylinders, this is not always the best guide when real world conditions are applied. There is no right or wrong solution: instead, people should think more about their own circumstances and habits before they decide which to go for.”

The findings have been disputed by combi boiler manufacturers.

Worcester points out that the study does not provide a full analysis of hot water usage analysis. Martyn Bridges, Director of Marketing and Technical Support, comments: “The report’s suggestion that combi boilers may not be as efficient as often claimed results from simply taking the gas meter readings at each property. It accounts for all gas consumption, which fails to tell the whole story. The absence of any figures relating to hot water usage and performance is notable and significantly limits the credibility of the claims.”

Other sources Martyn points out that the research fails to acknowledge the possibility that gas could also be used by secondary sources to the boiler, such as a gas fire or cooker. He also believes the study is flawed because it presumes that less hot

water is used in the summertime, which is in contrast to the surveys Worcester has undertaken.

“Our findings are that when the weather is hotter, people tend to shower or bathe at least once, sometimes twice a day, so it is unsurprising that there was more gas consumed than the surveyors expected,” says Martyn.

“This report doesn’t seem to be as scientific as it should be when making such strong claims,” he adds. “Until there is an accurate survey undertaken where the electronic measurement of hot water usage sits alongside gas consumption, I question whether such alarming headlines can be made with any real conviction.”

Baxi has also weighed in, with Regulatory Marketing Manager Jeff House saying: “When a central heating system is being specified, there isn’t a single fit-all solution.

Installers should advise their customers on a case-by-case basis,

and making a decision between a combi boiler and a hot water cylinder will largely depend on the number of bathrooms within the property and the household’s hot water requirements and use patterns.”

Energy labels Jeff adds that the recent introduction of ErP (Energy-related Products) labels on combi boilers and hot water cylinders should help both installers and consumers make a more informed choice by enabling them to compare hot water efficiencies.

“It is worth considering that due to differences in design and materials used in heat exchanger construction, the resultant thermal mass can vary greatly between product ranges and manufacturers – therefore some of the findings observed in Sustainable Homes’s study cannot be attributed to all combi boilers,” concludes Jeff.

£100 Star Letter Confusion about CO alarms

responsibility – that of checking these CO alarms. The golden opportunity here, to make CO alarms mandatory in all new appliance insta llations and in rented and publ ic access properties, seems to have been missed. It would have saved a great deal of conf usion and supported good safety practice. Sadly, we still live in times where for many, the cost of putting food on the table far outweighs the good practice of a gas appliance serv ice. This small issue of a CO alarm insta lled could be a life-saver.

So many of us seem to be misg uided rega rdin g CO alarms. There has been widespread publ icity in the trade press about the new regu lation rega rdin g CO alarms for land lords, but most stories haven’t clari fied that this is only mandatory for build ings with solid fuel appliances. There has been conf usion from tena nts, land lords, gas insta llers, retai l outlets, merchants and even the press regarding this requirement, which is only now becoming evident.

New is not always best

Traffic jams could cost employers

I write with reference to the recent story about calls for a scrappage scheme to replace water wasting toilets. Having had to change old sanitaryware and other plumbing fittings over the years, I would like to point out that although the modern flushing units may hold less water than the old, they do not flush away the waste products as well as the old units. So one often has to flush units a few times to obtain a clean unit.

This may be due to the design of the pan which in my opinion has been changed so much over the years that it can in many cases no longer be termed a sanitary appliance. Change has been driven by the aesthetic appeal of its shape rather than its efficiency. While many of the taps on basins and baths use less water they do not help the environment as most of them wear out in a fraction of the time that the old ones did.

The same is true of modern boilers. I would love to see research on the overall cost of maintenance and renewal on modern boilers compared to the old ones. The biggest problem with water consumption is that we have too many people in the country.

I read with interest an article in your last issue about a new European ruling that could mean travelling to the first and last appointments of a working day will be viewed as work time.

I wish that ruling had come into force five years ago when I spent more time than I care to think trying to get home at the end of the day but travelling at a snail’s pace on the M25. I’m sure my boss would have been only too pleased to boost my earnings as the hours clocked by. Now that I run my own business, I’m not so sure I like the idea!

In all seriousness, it sounds like another idea from Europe that will cause more problems that it solves. How can an employer be sure that operatives are truthful about the time it takes them to get to and from an appointment at the beginning and end of the day? Also, why should companies be penalised for the never ending congestion on our roads? It’s another extra cost that many businesses could do without.

The benefits of experience Also being 68 years old this year, I sympathise with Allan Marshall (last month’s star letter) a qualified heating engineer who is finding that nobody is interested in the skills he has gained, which you cannot buy from today’s training centres at any cost. That’s because it takes a life time to reach the level of skills we pensionedoff trades people will take to our graves.

My own hands-on skills come from being multi-skilled, following the purchase of a detached house near Bournemouth, nearly 40 years ago, which needed total modernisation. The property refurbishing skills I gained led to opening a small local plumbing and heating supply business, which expanded into importing radiators to opening a luxury bathroom business.

As always in the UK, if your business is related to the ups and downs of the property market, there’s a good chance that you will go bankrupt, as I did in 1990, due to banks lending to property speculators.

The skill sector I moved into was in renewables, after developing my own version of a thermal store, which needed pre-heated water to become more efficient to that of existing hot water tanks.

This is when I started to look into solar water heating, which attracted me into designing and developing a heat pipe collector, with production in China, so I could export worldwide. I had a lot of success until another banking crises hit the world in 2008/9, just at the time my second design was being shipped to the USA as well as the UK. Like 1990, I ended up placing the business into administration.

In late 2010 I returned to China to continue what I started and to find a way to use all my 20 years of past thermal store, plumbing and heat pipe collector skills and experience.

The biggest challenge was developing a solar water heating system that could compete with the crazy subsidy system that catapulted solar PV to the level it has reached today, while solar water heating sales have returned to the days before any government support.

I’m happy to report that I have enjoyed huge success of my flat pack thermal store commercial tank kits in South Africa, and growing exports of my Speedflex preinsulated flexible plumbing pipe systems to such countries as Italy, South Africa, Costa Rica, and the USA. I have also one importer in the UK who sells his solar water heating systems through eBay, with no interest in any government red tape and stop-start policy.

To all those pensioned-off trades people with skills going to waste, feel free to contact me. The training centres may not need you,

but the rest of the world does, and that is where we are seeing our market growing without the red tape and government policy changes that will bankrupt many, who have stayed focused on just selling and installing solar PV systems.

It may be time to return to solar water heating, but not as written up by DECC, which only allowed a solar thermal collector to heat a unvented tank of water to 65°C for around £5000 installed The new future for solar thermal central heating (as installed in my house 12 years ago) is the integrated combination of a thermal store, heat pipe tube collectors or PV + Thermal = PVT and a water to water heat pump to replace all other types of fuel producing hot water devices.

To the many Allan’s of the UK, look to eBay, as I did, to sell your experience and knowledge and earn some extra money to supplement your pensions.

Pointless certification I write following a report in your last issue about plans to develop an alternative scheme to the MCS. Were it not in your November/ December issue, I would have thought it was an April Fools news item! With the RHI something of a miserable failure, what possible incentive could any self-respecting installer have to peruse such a certification? On top of that, who has customers looking to install renewables these days?

The truth is, even in the better days of the RHI scheme it would have been cheaper for most customers to get a non-MCS certified installation because there was no onus on any party to have MCS/RHI paperwork, no Green Deal Report, no EPC report, etc, all of which added a significant premium to the installation. And unless an installation company were putting in dozens of renewable systems per year, it would never see a profit and may in fact take a loss.

The article you published also said that the new scheme could save an installer between £1500 and £2000 on getting certified, which suggests it would still be a very expensive and burdensome procedure.

What we as installers need to do is focus on providing good work and not waste our time getting pointless certifications that don’t seem to benefit anyone in the long run.

14 Green Matters

Don’t ignore demand for solar thermal The UK market for solar thermal systems has not benefitted from the financial rewards available for solar PV, but there are many applications where it could play a big part in reducing energy bills. Chris Laughton, MD of the Solar Design Company, explains more.

W

ith the Government appearing hesitant on continuing support for photovoltaics (PV), we should not forget the Renewable Heat Incentive (RHI). In its household and commercial forms, the RHI financially rewards the system owner for generating heat from renewable sources such as solar. There is now an opportunity for PV installers to expand into solar thermal, transferring their core skills and using government subsidies to maximise sales interest.

This cross-over of technology is possible not simply because of common sales and warehousing techniques but also because there are common installation techniques for roof access, roof fixings and site assessment. MCSaccredited installers will also have the necessary office procedures in place, so adding another technology is relatively easy.

Extra business There is also plenty of business to be had outside the MCS and grant schemes, as many applications do not currently enjoy grant support. One advantage is the absence of related paperwork overheads. Both swimming pools and space heating (neither currently qualifying for RHI funding) benefit from solar thermal, reducing costs and atmospheric emissions, and increased independence.

Swimming pool operators know that a lot of energy is needed to gain even a few degrees in pool temperature.

Solar heating works well here, as the filtration system already has to run at high circulation rates. This requires only a modest temperature rise across the collectors, so cheaper unglazed collectors can be used (if combined with hot water heating (DHW), glazed collectors tend to be used). In all cases, sizing ratios need careful design, with collector arrays often filling pool roofs.

In demand Solar space heating support is all the rage in Northern Europe (where it is known as solar combi-systems), but is surprisingly little seen in the UK. Off-the-shelf underfloor heating designs using solar thermal can contribute around 10% of annual demand for well-insulated homes.

Historically, solar thermal has been used for DHW – as less roof area is needed to provide the same contribution of solar energy than compared to PV. But the advent of intelligent switching of electrical appliances (matching peak PV generation) means that PV-powered DHW electrical resistance elements for DHW are more common – meaning that larger heating loads are now most attractive for solar thermal.

Many commercial applications have high process heat demands – including agriculture (milking parlours), food production wash-downs, and cleaning (car washes, holiday accommodation), offering good returns for solar thermal.

With the advent of improvements in district heating, there is now no reason why we can’t also see the success of large solar thermal arrays serving wider communities with other renewable sources.

Air collectors Solar air collectors are becoming more popular. Glazed or unglazed, they can be used on vertical facades as well as roofs. Energy savings result from adding a few degrees of heat to the incoming ventilation air (assuming a forced air supply is already necessary in the building).

Fans, ducts and in-line heat exchangers provide a full ventilation and heating solution.

Some new skills will be needed – and training courses are available to assist this. The movement, transfer and storage of heat is fundamentally different to the way we

treat electricity. For example, interaction with other heat sources (such as gas, oil, biomass and heat pumps) has to be considered. Solar thermal generally acts in tandem with other heat sources, so some understanding of heat engineering is necessary to optimise system performance.

Energy Labelling to EU 2010/30/EU is now very straightforward for solar thermal when using commercial design software, such as our own T*SOL 2016. Once the system is designed and checked, the energy label is automatically generated.

There has been a solar thermal market established in the UK for decades, without any grant support, and it can develop and grow again with a change in sales technique that emphasises independence of supply and fuel and emission savings. www.solardesign.co.uk

An Edinburgh home has won recognition for the range of different energy saving and renewable energy generation technologies in the house, winning the Best Integrated Renewable System as part of the Solar Power Portal Awards. The property was designed by architect Rob Goodburn, who set out to create a zero-carbon, green home. He enlisted the help of local Edinburgh solar specialists Solar Kingdom to optimise the integrated use of the technologies.

The new property includes extensive insulation, triple glazed windows and doors, a whole house heat recovery system, LED lighting, solar PV and solar thermal panels integrated into the roof covering.

Peter Randall from Solar Kingdom says: “Working with Rob on this project has been a joy. He has the most in-depth knowledge of both building performance and the positive impact renewable technologies can have of any architect I have worked with. Combining this with my own expertise allowed us to fully realise the project’s potential. The end result is a great looking house anyone would aspire to own.”

A study of the building’s performance once the family has lived there for a while is planned in conjunction with a local university and the Building Research Establishment (BRE) to evaluate aspects of the building’s performance.

Green Matters 15 Harvesting the heat from local sewage

Banking energy for winter use A mini heat pump from Vaillant has been installed as part of a project between sustainability specialists Caplin Homes and academics at De Montfort University studying the effectiveness of the Earth Energy Bank (EEB), an inter-seasonal heat store. The scheme aims to evaluate the operation of the EEB within a retrofit setting, where the building envelope is relatively inefficient.

Vaillant’s 3kW geoTHERM mini heat pump has also been installed in the test property.

Designed for retrofitting to multi-occupancy buildings, the geoTHERM was first installed in a high-rise in Manchester, but the company is keen to apply it to new build applications.

John Bailey at Vaillant says: “We believe ground source

Sewage is now being used to power a heating system at the Scottish Borders Campus.

The SHARC heat recovery system intercepts waste water from a sewer close to the local treatment works operated by Scottish Water.

The system uses a heat pump to amplify the natural

systems have a great deal of potential and the Earth Energy Bank could be a real stepping stone to their more widespread adoption.”

As a cost effective alternative to traditional ground loop or deep bore systems, the EEB is said to make achieving low and zero carbon much more affordable.

Because the project is housed in an existing terrace house, the EEB has been specially insulated so it could be located beneath a lawn on the campus. It works in conjunction with the geoTHERM Mini heat pump and a solar array housed on the building’s roof. Surplus energy generated during the summer months is used to warm the energy store, which is then drawn upon to heat the home in winter.

warmth of waste water, and the heat produced is being

sold to Borders College under a 20 year purchase

agreement, producing savings in energy, costs and carbon emissions.

The system now provides around 95% of the heat needed by the Galashiels campus and does not impact on the normal operation of the local waste water network. This solution is expected to help meet the college’s carbon reduction targets, while offering long term price certainty and local control.

Need to focus on workable solutions OFTEC has submitted recommendations to the Energy and Climate Change Select Committee calling for the UK’s low carbon heat strategy to focus on incentivising solutions that are simple, affordable to install, impose limited disruption on the homeowner, and offer competitive running costs.

The oil organisation acknowledges that 100% renewable heating solutions can provide a workable solution for some properties such as new builds, and will play a role in the UK’s future heating mix.

However, it believes that, in reality, these technologies are currently too expensive and impractical for the vast majority of UK households

to realistically consider installing.

Director General Jeremey Hawksley says: “OFTEC is committed to working towards a low carbon future for heating and recognises that 100% renewable technologies can work well in some properties.

“However, the poor energy efficiency of the UK’s housing stock, particularly older, rural, off-grid homes, plus the high up front cost of renewable technologies of between £9000 and £17,000, means the majority of UK households just aren’t in the position to make this large leap towards wholly renewable heating, even with incentive payments.

A change of approach is clearly needed.”

COMPANY Spotlight 17

Hot water specialist continues to advance Celebrating 10 years in business in 2016, Walsall based Advance Appliances provides a range of hot water solutions for both traditional and renewable systems. PHAM News reporter Sam Jackson met with company founder Geoff Egginton to find out more.

N

ow in its tenth year of trading, hot water cylinder specialist Advance Appliances has very effectively carved out a niche for itself.

From thermal stores and heat pump cylinders to buffer tanks, the Midlands-based company has made the move from standard designs to tailored, bespoke services and has put energy efficiency and renewables firmly in the foreground of its product specifications.

However, the company was not always as wide-ranging as it is today. Owner Geoff Egginton recalls how the business began: “I started Advance Appliances after 10 years working for Albion Water Heaters in order to start my own water heating business as an original equipment manufacturer (OEM). My experience at Albion meant that I knew a lot about the products in the sector and how the industry worked,” he explains. “It was definitely a niche company. We were selling unvented cylinders and the company grew steadily for three years.”

As its reputation expanded, Advance Appliances enjoyed a steady demand for its products. However, in the run-up to the credit crunch the company could see that demand was slowing down and that a different approach would have to be taken.

Customer input Geoff explains how the voice of the customer started to become an increasingly important part of the firm’s business model. “I had to develop the company in a very poor business climate, so it was important to develop close ties with our customers and manufacturer partners. We needed to work with them to ensure that our product offering was what the market needed, and the way our products look now is really down to those strong relationships,” he states.

“The business actually grew significantly in 2009, after we began developing thermal stores.

We introduced them in order to diversify our product range and we were able to provide models unavailable from elsewhere.”

All of the company’s cylinders now feature

labelling under the EU’s Energy-related Product Initiative.

Most of company’s products currently achieve ‘B’ and ‘C’ ratings, but Geoff emphasises that Advance Appliances will be striving for even higher ratings in the near future.

“We want to aspire to get A’s and B’s,” he says. “Plans are in place to achieve those higher ratings. The new directive is encouraging companies to improve energy efficiency and that has to be a good thing,” he adds.

This kind of customer service is critical to our business, as we don’t offer the same volume as other firms but we do offer a tailored service,” he explains.

Multi-fuel solution As well as ErP labelling, Geoff is also a strong supporter of renewables. Advance Appliances already provides cylinders for use with heat pumps, solar power or biomass, and has now introduced an upgrade to its SFUTS Multi Fuel Thermal Store.

The pre-wired and pre-plumbed stainless steel unit comes with two electronic timers and three ‘A’ rated pumps for integrating oil or gas boilers with solid fuel appliances for mains pressure hot water and sealed central heating. The store also has a coil for solar thermal and two immersion heaters fitted for back up or for use with PV solar.

The company’s backing of renewables comes at a difficult time for green energy, with the current Government planning to cut subsidies to solar and reduce incentives to invest in renewable energy. It’s not a policy that Geoff agrees with.

“I’m disappointed with the decision to cut funding as it is such an important part of the industry,” he argues. “These cuts make it increasingly difficult for manufacturers to plan ahead, making things even harder for us.”

Customer service Soon to be launched, the new Plug & Glow unit is a mini electric flow boiler that can provide a boost to an existing gas or oil system or used to maximise the benefits of solar PV systems.

The compact unit, which can be programmed up to 20 times a day, seven days a week, comes with a 13A plug, has 22mm connections, and delivers a 2.7kW output.

17.indd 1

However, the company continues to prosper and Geoff emphasises the importance of Advance Appliances’ approach to customer service. Recent years have seen the company shift its focus to a more bespoke service and he believes this has given the business a significant boost.

“We pride ourselves on spending a lot of time talking to a variety of people about how to do things, and even if it is something not connected with us we will offer our help.

Peace of mind Advance Appliances has been recognised for its services by the Hot Water Association (HWA) and as such is now an audited HWA Charter member. This means the company is required to meet or exceed appropriate standards and regulations and provide technical support before and after installation, along with giving clear warranty details to customers.

Geoff is particularly proud of this recognition. “It is important for us to be seen as ‘fitting the bill’ by an external body. As a small company we are proud to be involved in the Association. We like to give customers peace of mind when things don’t go quite the way that is expected and our membership of the HWA reinforces this,” he says.

Having already achieved a significant amount in the decade that the company has been operating, Advance Appliances still has products and ideas that are yet to come to fruition. The company is constantly looking to develop new innovations to improve its current range, and Geoff stresses the importance of renewables innovation.

“With Feed-in Tariffs getting ever lower it is important to get the most out of available energy,” he explains.

Among the products the company is hoping to release this year is a simple one-box solution to maximise PV inputs to immersion heaters. “We have worked on the product for two years so we are very excited about its launch,” he says.

With all of this in the pipeline, the company is looking to raise its profile in the coming months and years, with Geoff wanting the business to keep on growing. “I do hope that we have a bigger presence in the market in the future. We have grown by a factor of four since we started out and if in ten years time we have grown by the same factor, I would be very happy with that.” www.advanceappliances.co.uk

The relevant legislation uses two key terms when outlining the parties involved – the ‘producer’, who is the manufacturer, and the ‘seller’, who is the merchant or stockist. The following examples are designed to provide an idea of how installers could be affected by fitting non-genuine parts.

UNDERFLOOR HEATING 23

Laying down the best possible UFH system Achieving a tailored underfloor heating installation that maximises efficiency and output can be a tricky proposition, but help is available to installers which will enable them to deliver the best possible results for their customers. Gareth Samuel, Product Manager for Hep2O at Wavin, provides some advice on how to deliver a hassle free installation.

A

nyone looking to install the ideal underfloor heating (UFH) system will soon be aware that there are several options to choose from to suit different applications, so correct system selection is essential to a successful installation. But using a combination of forward planning, the right advice from leading manufacturers and the latest userfriendly design tools, the process can be made more straightforward than many installers would imagine.

The Hep2O underfloor heating range includes various manifold solutions that can be tailored to each situation

Installation is made easier by plastic plates with pre-formed grips to hold the pipe and ensure uniform spacing

Planning ahead

The right layout

The most important aspect of choosing the right system is to ensure it is appropriate for the floor type, whether that is a new or existing screeded floor or one of dry construction, i.e. battened or joisted timber floor. It can be more costeffective to install a UFH system into a new screeded floor for example, however this requires planning to schedule the installation into the construction programme.

Another reason to take an early look at wider considerations in a project is to avoid over-specification, which can occur if installers focus on a room’s dimensions rather than its eventual contents. Not factoring in the issue that UFH pipe should not run underneath fixtures such as kitchen units when pricing a job will mean wasted time and products from changing a design half way through a project.

is wired in parallel, avoiding the need for an individual connection from each thermostat to the control centre. The modular manifold also enables installers to order exactly the number of ports they need, saving on wastage and potentially reducing the size required.

Correct pipe layout is another core requirement for achieving an effective installation, as pipe runs need to be placed with consistently spaced centres to provide consistent heat output across a room. For new build construction, typical Tailored service heat output using 15mm pipe and a boiler, recommended With a wide range of underfloor heating systems available to pipe spacing is at 200mm centres.

The System Plates system from Hep2O has been designed suit different requirements, gaining knowledge is essential to enable installers to easily achieve uniform spacing on for installers to take the initiative in projects and provide screeded floors, with pipes arranged in a spiral pattern the most tailored result to clients. To complement the expert installed in plastic plates with pre-formed grips that hold advice that we can provide at Wavin, the company has and protect the pipe.

24 UNDERFLOOR HEATING

Comprehensive design covers all the bases Before taking on any underfloor heating project, it is important to have a comprehensive design that takes into account even the smallest of details. James Lavers, Nu-Heat Design Manager, looks at some of the steps necessary for an effective and efficient installation.

W

hen it comes to installing UFH, a good system design can make all the difference. What you might not know is that a quality design offers far more than a tube layout drawing – it should also provide the essential information needed for a straightforward installation and commissioning process which allows the supplier to guarantee system performance.

So, how do you spot a good James Lavers, Nu-Heat UFH design and what should you be looking for? To begin with, the design ought to be bespoke to the project, drawn up based on floor plans whilst taking specific factors into account to create an efficient solution. You can expect the property to be carefully assessed by the system designer, considering everything from insulation levels to the chosen floor covering, as even the smallest of details can affect the eventual system specification. For example, in a room with more windows and a higher heat loss, it may require a higher heat output and closer tube spacing.

Heat loss Working out the property’s heat loss is an important stage not to be underestimated – if the heat losses are too high then any heating system will struggle to effectively heat the rooms. Each room experiences a different heat loss, which is why they should be calculated on a room-by-room basis. Insulation levels is one of the factors that can affect a room’s heat loss.

The better the room insulation, the lower its heat loss will be. Each element of the room (walls, windows, ceiling, etc.) will lose heat and the amount lost can be calculated by looking at each element’s u-value. The u-value indicates how well something transmits heat and a lower u-value corresponds to a better-performing building element.

Nu-Heat’s LoPro Max UFH being installed in a renovation

24.indd 1

Manuals and design drawings support an easy installation

A tube layout drawing provides a clear picture of the work

The number of external walls and windows in a room will affect the heat loss, too. A room with just one external wall and one double glazed window will experience far less heat loss than one with three external walls and three large windows. There will be less heat loss in an area with heated rooms above and/or below. Rooms over unheated voids, such as suspended timber ground floors, will have a higher heat loss.

Flow temperature

Once the heat and ventilation losses, usable floor space and the floor coverings are known, the actual design of the UFH system begins. This is where you need to take tube spacing into account. By spacing the UFH tube at closer centres, more can be installed in the room to achieve a higher output.

A higher flow temperate will increase the heat output. Some Ventilation issues heat sources, particularly renewable solutions such as heat All of the above factors are fabric losses, where heat is pumps, operate more efficiently at lower flow temperatures, so physically lost through elements of the building such as deciding on the flow temperature is always a balance between walls, glass and the ceiling. There are also ventilation being high enough to heat the property and low enough to losses to consider. In order to make a building a comfortable maximise the efficiency of the heat source.

“Even the smallest of details can affect The flow rate is the speed Since the fresh air entering the eventual system specification” at which the warm water the building will be cooler circulates around the room than the warm stale air it before returning back to the manifold. The faster the water replaces, heat will be lost through these air changes.

However, give a figure for each individual room’s heat loss, making it the design must make sure that the circulation pump is sized possible to design the UFH to reach the desired temperatures. correctly in order to generate enough flow to achieve the Designing the UFH to meet the heat demand involves desired flow rate around the underfloor heating tube. working out how much heat energy the UFH needs to Tube layout emit in order to heat each room effectively, but before the specific design is decided, factors that dictate the design With all of the information prepared and the most suitable UFH floor construction chosen, the designer can now begin temperature should also be carefully considered. working on the tube layout drawings.

26 UNDERFLOOR HEATING

Taking care of vulnerable users With lower operating temperatures, easy maintenance and reduced running costs, underfloor heating can provide an ideal solution for care environments. Matt Lowe, Managing Director at commercial heating specialist Giacomini UK, highlights some of the key benefits.

I

n the recent Spending Review and Autumn Statement, Chancellor George Osborne presented the Government’s target to build around 8000 specialist homes for older residents and people with disabilities over the next five years.

This is to be funded by £400 million of funding for housing associations and the private sector.

With a rapidly ageing population demanding high standards of both housing Matt Lowe, Giacomini MD and care, there has been a noticeable increase in the popularity of extra-care developments. According to the Elderly Accommodation Counsel (the EAC) there are now approximately 60,000 extra-care housing units in England.

Extra-care schemes provide self-contained homes for older people that offer support services and a safe environment to enable self-care and independent living.

To provide an optimum environment for residents, there is growing attention being given to their thermal comfort needs, and underfloor heating is fast becoming the top choice for such developments.

Safer temperatures The design of the heating system should take into account the most vulnerable people that may use the space. Underfloor heating avoids many of the risks that are present with convectional radiators. For example, the surface temperature of convectional radiators and the associated pipework can reach 75°C. These temperatures can cause serious burns if contact is made. Thankfully, underfloor heating removes the risk of burns due to its use of lower operating temperatures. The large surface area of the floor means the system does not have to be heated to the same high temperatures as a radiator, heating the floor to a temperature of between 27°C to 35°C. Furthermore, underfloor heating avoids the risk of injuries associated with the sharp edges on conventional radiators, freeing wall space from clutter and unnecessary hazards.

Underfloor heating systems are designed to warm large surface areas, which means that the system does not have to be heated to the same high temperature as a radiator

A Giacomini system was recently installed at the Ronald MacDonald House, designed to cater for the families of sick children in Glasgow’s new Southern General Hospital

Underfloor heating is also effective in evaporating water splashes and spills from tiled floors in bathrooms, wet rooms and kitchens, lessening the likelihood of slips and falls in these areas.

As well as minimising risk, underfloor heating can be beneficial in creating a healthy environment. The reduced air movement from a radiant system means a reduction in dust and airborne germs, so homes are cleaner and healthier. This is important for those with asthma and other respiratory issues. By warming the floor area first, underfloor heating reduces the moisture levels within the floor, making it too dry for dust mites to survive in carpets.

regular maintenance costs to incur unlike traditional convection heating. If maintenance is required it is easy to manage as all connections are located in one place (at the manifold).

Both parties can also benefit from how easily the system can be controlled using room thermostats. Choosing the correct control system is crucial in ensuring that your heating system works in the best possible way, efficiently and easily. At Giacomini we have carefully selected a range of room thermostats for both communal and individual living areas.

When considering communal areas, the thermostats provided are often tamperproof. This prevents the temperature from being adjusted outside of the recommended range. For individual room thermostats, visibility and ease of use are listed as some of the main priorities. With this in mind analogue controls tend to be most suited to this application.

All this, without forgetting the benefits to be gained from underfloor heating’s performance and energy efficiency. By heating almost entirely by radiation, underfloor heating is one of the most efficient and comfortable forms of heating.

Traditional radiator systems only heat the area around them, causing the heat to rise above the cooler air surrounding it. With underfloor heating the whole floor becomes an emitter for the radiated heat. The energy reaches into every corner of the room evenly, giving a consistent temperature throughout the space, which means no cold spots, no warm ceiling and no cold feet! It can also retain heat for longer than a radiator can after the system has been switched off.

Keeping clean Preserving a hygienic environment can be challenging in areas of multiple occupancy. Bulky radiators have a tendency to attract and build up dust. They are extremely difficult to clean in between and behind, and therefore are not the most hygienic option. Underfloor heating helps create a healthy indoor environment by freeing up space and making rooms easier to clean.

A huge advantage to both extra-care providers and residents is underfloor heating’s reduced maintenance costs. The system is virtually maintenance free, with no

Save time with screed free system With the aim of addressing some of the potential installation issues associated with hydronic UFH systems, such as floor height restrictions and the inability to immediately tile directly over the system, Warmup’s new Total-16 Low Profile System is a thin, durable, hydronic system that doesn’t require any screed.

As the system does not need to heat the screed, the company says that this time saving solution is able to heat up a room in a matter of minutes rather than hours.

Total-16 comprises three modular boards – straight,

The straight boards come complete with pre-installed aluminium heat diffusion plates. At only 16mm thick, with a 12mm PEX-A pipe, the

system will have minimal impact on floor levels. This, says the company, makes it particularly suitable for retrofitting, and installations to off-plan specifications.

With the three boards weighing a total of only 1.7kg, the system is lightweight and easy to handle, allowing for rapid installation. The high density, moulded EPS supports up to 40 tonnes per m², making light work of heavy loads.

The Total-16 system comes complete with a lifetime warranty and ‘SafetyNet’ installation guarantee. This means that if the system is accidentally damaged during installation, Warmup pledges to replace it free of charge.

Lower running costs As mentioned previously, the large surface area of the floor means the system does not have to be heated to the same high temperatures as a radiator. By distributing heat through the use of lower operating temperatures, an underfloor heating system can reduce running costs by up to 30%.

The low flow and return temperatures also allow underfloor heating to successfully connect with many renewable technologies, for example heat pumps, biomass boilers or solar thermal systems. This allows for further reductions in energy costs and carbon footprint.

With all of these advantages, it is clear to see why underfloor heating is increasingly installed in both new build extra-care developments and retrospectively into refurbishment projects to improve existing care facilities. www.giacomini.co.uk

28 UNDERFLOOR HEATING

Getting on top of UFH demand With demand for underfloor heating continuing to rise, installers who ignore this part of the heating market could be missing out on a profitable revenue stream. Andy Coy, Product Manager at Polypipe Underfloor Heating, highlights some of the key selling points.

U

nderfloor heating is not a new notion, but its popularity is on the rise once again.

Compared to radiators, water based underfloor heating provides plenty of economic, environmental and aesthetic benefits. Distributing heat evenly throughout the home, water based systems work by gently heating water in a network of pipes. The hot air then rises from floor to ceiling, creating a consistent and ambient temperature Andy Coy from Polypipe throughout.

Radiators project heat using a rising convection current of hot air which results in hot and cold patches throughout the home. The convection current produced via radiators also circulates dust and carpet mites around the room, which can increase and exacerbate cases of asthma and other respiratory conditions.

Water based underfloor heating is a much more energy efficient way to heat a home when compared with radiators.

This is a very important consideration for the modern homeowner. Energy experts are increasingly recommending underfloor heating over traditional heating options to fulfil household efficiency benchmarks, especially when combined with the use of a ground or air source heat pump.

More for less Due to its size and dimensions, underfloor heating is able to run at a lower temperature when compared to radiators.

Underfloor heating systems can operate effectively at temperatures between 40 and 60°C. In contrast, radiators require the water to be much hotter at 70 to 80°C. This means less energy, approximately 15-40%, is required for the same heat output, ultimately lowering household energy costs and consequent energy bills.

Water based underfloor heating also boasts many environmental benefits when compared with radiators, which all come down to one point – underfloor heating requires less energy to run. The design and layout of underfloor heating means that no heat output is wasted.

More importantly, underfloor heating can also draw energy from renewable sources. Due to the much lower operating temperatures required, it can be used in conjunction with ground and air source heat pumps, which extract warmth from the air around the property or the earth in the garden. This increases energy efficiency ratings, reducing CO2 emissions and cutting carbon footprints.

Design freedom Aside from the economic benefits, underfloor heating provides many interior design benefits.

Aesthetically, radiators provide interior design issues for many people. Rooms are designed around the bulky unsightly equipment, which often hinders the design Polypipe’s overlay system process.

As the name implies, underfloor offers a potential heating is installed under the floor, solution for existing floors meaning the need for radiators is diminished and room designs are no longer constricted by radiators. This allows room for complete design freedom that makes underfloor heating an attractive prospect to those building or renovating their homes, and thus drives the market demand for the technology.

Alongside providing performance and design benefits, underfloor heating is incredibly versatile and can be

installed under all floor coverings, in new builds and as part of renovations, making it an ideal universal product for all installers.

Screeded floor systems are perfect for new build projects, where the floor is yet to be constructed. In this instance, the piping is fitted directly into the floor and covered with screed before finally laying the floor covering on top.

When expensive and disruptive floor excavation is not a possibility, overlay systems are perfect for fitting over existing floors, and are well suited to renovation projects, or as a later addition to a new build project.

Overlay systems (just 18mm deep in the case of our own offering) can be fitted over existing floors and are a preferable option for renovating a home or as a later addition to new build projects if the flooring has already been installed.

Overlay systems are ideal for heavy-weight floor coverings like ceramic tiles, or where the floor covering needs to be secured directly to the panel, such as solid wood.

Install with confidence Professional installers should not be frightened of working with underfloor heating and look to benefit from the new profit stream open to them through this technology. With increasing consumer demand, now is the time for installers to do their research and select a reliable underfloor heating manufacturing partner.

Many heating and plumbing engineers are reluctant to install underfloor heating due to a lack of training and support. With qualifications and support available from recognisable brands, like Polypipe, this no longer needs to be the case. There’s no reason why any installer shouldn’t be able to offer technical advice and guidance to homeowners, with the potential to add water based underfloor heating to their offering.

At Polypipe we have established a Registered Installer Network (RIN), which ensures all registered installers are BPEC qualified, with training, tech support, design advice and business leads provided, helping installers grow their business.

UFH helps to achieve ‘A’ rated results The Floortec underfloor heating system from Myson has been installed throughout a new build property with an ‘A’ rated Energy Performance Certificate (EPC).

The property also boasts a whole house ventilation system with heat recovery, a rainwater-harvesting system to service the toilets, washing machines and outside taps as well as triple glazing and high quality insulation. The culmination of these energy saving features and the Myson Floortec system has resulted in the property being one of few in the country to achieve an ‘A’ rated EPC. Martin Smart, Director at Hayward Smart Architects,

who designed the project as his new home, comments: “The site has no mains gas and we wanted to move away from the carbon emissions associated with oil, so opted for an electric air source heat pump which is supplied with electricity from roof mounted solar PV panels. Because this source of heat is best suited to low temperature heating systems, installing an underfloor heating system was a natural choice. We have also designed the house with solid floors on both levels to create greater thermal mass.”

As well as being designed to work with all floor types, including solid, suspended, and floating floors, the

Floortec system is also available with Myson’s new Microboard fixing system which allows underfloor heating to be retrofitted in existing properties.

Another option is Floortec single room heating packs,

which contain everything needed to provide additional warmth in rooms of up to 40m2. This allows single room extensions in places such as the kitchen or conservatory, where wall space can be at a premium.

Myson has also recently developed a new range of underfloor heating pipe.

PEXcellent 5 is manufactured without chemicals and solvents for greener production and end of life cycle disposal and is covered

by a 10 year system guarantee for extra peace of mind.

30 UNDERFLOOR Heating

Retrofit system is The benefits of flexibility easy to install The SuperFlex pipe system from Continental Underfloor is said to make any underfloor application faster, easier and safer. The pipe can be bent at a radius of less than 100mm, an improvement on the internal bend radius of 150mm offered by most pipes used in underfloor heating.

The flexibility of the pipe product means that kinks are

eliminated when it is installed, so avoiding expensive pipe being replaced and allowing the system to operate more effectively. The supple nature of the product means it can be also installed quickly and safely, even during cold conditions.

SuperFlex also allows low temperature heat sources to be used. A typical UFH system

connected to a heat pump, for example, with pipe spacing of 150mm, operates at a flow temperature of 40-45°C, but because SuperFlex can be installed at 100mm centres, the system’s flow temperature can be reduced to 35°C, further boosting the efficiency of the system.

Avoid cracks with electric UFH system The Minitec UFH system from Uponor is claimed to be one of the thinnest systems on the market, with a finished installation adding as little as 2cm to the f loor. Designed to be installed on top of existing screed or tile f loors, the system’s proximity to the surface is said to reduce heat-up times, providing the same level of comfort at a much lower operating temperature compared to other retrofit heating systems.

The water-based system can be fitted by just one installer and uses adhesive panels with raised foil naps and prepared grooves to guide the pipe loops, which can be laid at both 45° and 90° angles across the floor.

The pipe can simply be clicked into place by the installer, avoiding the need for any specialist tools, and then connected to the manifold as with any traditional UFH system.

The Vario PRO system from Thermogroup UK combines electric underfloor heating cables with an uncoupling, crack isolation and waterproofing membrane.

It enables installers to prepare difficult substrates, prevent tile delamination and install a flexible electric underfloor heating system in one process.

Applying the membrane combined with uncoupling technology means the floor will be warm and comfortable thanks to the electric underfloor heating and,

because of the uncoupling membrane, there will be no cracking issues in the tiles or

grouting later down the line.

Installation of Vario PRO begins with fixing the Vario

ProMat membrane to the floor using a flexible tile adhesive and then laying the electric underfloor heating cable into the grooves in the matting until it has covered the desired heated area. Tiles can then be laid directly over the uncoupling membrane and underfloor heating cable.

Alternatively, a 10mm layer of self levelling compound could be laid, followed by installation of a compatible carpet, vinyl or timber floor.

School finds the Ideal boiler solution

Selected for control Alpha Heating Innovation has installed two of its Ares Tec boilers at a research and development facility in Fareham as part of the on-going testing of Searle’s dry coolers. The 660kW capacity boiler was chosen for its controllability, which allows Searle’s to test a variety of its products.

The search for a new boiler occurred after a fire broke out in one of Searle’s facilities. The company realised it would need to source boilers with varying capacity stages in order to satisfy certain conditions to be EuroVent Certified.

Searle chose Alpha because the boilers offered the optimum control and capacity, which fulfilled the company’s brief.

Daniel McDermott of Searle says: “We’re really pleased with our new test facility, as we have more control over the capacity using Alpha’s products. With two of the Ares Tec 660 installed, our set up can reach up to 1320kW, allowing us to test a variety of products and measure their capacities.

The easy access layout of the boiler also means maintenance is quick and simple, so our research isn’t slowed down whenever the boiler needs a service.” www.alpha-innovation.co.uk

Young plumbers pass the test at skills final The annual SkillPLUMB competition provides an opportunity for young plumbing apprentices to compete with fellow students and gain wider recognition for their accomplishments. So who came out on top when the 2015 regional winners went head-to-head in the final?

T

emperatures were running high at this year’s SkillPLUMB final where, following a series of challenging regional heats earlier in the year, 10 of the best young plumbers competed against each other in a bid to be crowned 2015 SkillPLUMB champion.

Now in its 8th year, SkillPLUMB is organised by BPEC, and has the Copper Initiative as its premier sponsor.

Contestants went head-to-head in a three day practical task at the Skills Show, the UK’s largest skills and careers event held between 19-21 November at the Birmingham NEC. In front of eagle-eyed judges and over 75,000 visitors watching their every move, the 10 contestants had to install a small domestic central heating system, a simulated shower enclosure, and kitchen with sink and washing machine, together with associated copper and plastic pipework.

Prior to the final, each competitor was given a ‘competition specification’ document which outlined the tasks and what judges would be looking for to help them get competition-ready.

Each task had to be completed within a strict time frame and was marked against tough criteria, including bend and joint quality, measuring and marking out, and material usage and overall presentation. Measurements needed to be within +/-2mm, and the bends within +/-1 degree of the specified dimensions. Visitors consisted of teachers, parents and hundreds of fellow students, increasing the pressure to put on a good performance.

On the morning of day three, competitors were able to show off their hard work to their friends, families and tutors with a public viewing of the completed test projects.

There was then a fun team building exercise where the group (including the judges) were split into two teams and had to build a self-supporting man or character out of a limited amount of materials. One team built a minion (from the Despicable Me film) and the other built the Statue of Liberty, with visitors asked to vote for their favourite.

“Over the three days we had an excellent turnout of visitors who were all really impressed with the standards of skill on display at our stand.”

For visitors and future apprentices, the three day event was both entertaining and motivating. Further inspiration was provided by more than 60 other competitions held at the Skills Show, all taking place in front of school children and their teachers.

Neil Collishaw continues: “The finals are inspirational to young people thinking of a vocational career and The Skills Show, with around 75,000 visitors, is an excellent platform to showcase the skills and talents of all finalists.”

Tailor made

Baxi offers free and paid-for courses at a number of locations around the country

to their customers. Over time this means the financial benefits can easily outweigh that relatively small investment of a day or two out of work.

When researching training, heating engineers should first assess whether the courses on offer meet their needs. If the basic content is there but you want to ensure a particular area is covered, it is always worth speaking to the training centre and asking if changes can be made. Likewise, if a course is scheduled at an inconvenient time, it is worth asking whether an alternative option is available – other installers may be in the same boat so an extra session can be arranged.

It’s not just the variety of training courses that has changed. Tailored options are becoming more accessible, helping to ensure that any installer can find a course that meets their requirements. Manufacturers have come a long way in recognising that courses have to fit around a heating engineer’s needs, so tailored doesn’t have to be expensive either. Don’t forget, it is in their interest to make sure that their products are installed and maintained correctly, so feedback is welcome.

Thinking differently about boilers Modern condensing boilers are often complex pieces of machinery, but Intergas Heating prides itself on offering a range of boilers that deliver high levels of energy efficiency with minimal moving parts. Carol Hitchcock attended one of the company’s training courses to find out more.

I

f you are the kind of installer who appreciates the rugged durability of the old cast iron boilers that predate condensing regulations, but also understands the importance of modern, high efficiency technology that conserves energy and delivers cost savings to customers, then it might be worth your while to sit in on Intergas Heating’s training course. It’s only a half day, but it’s packed with useful information about the Dutch manufacturer’s range of ‘A’ rated boilers, and there’s plenty of opportunity in the workshop to get your hands on the kit.

This isn’t a how-to course – if you are a registered gas engineer, you already have the knowledge to fit one of these with hardly a need to crack open the manual (but you always read the manual, right?). No, this course is an introduction to what will be to many installers a completely new idea in boiler engineering.

Constructed from only 12 components, just four of which are moving parts, Intergas boilers hold a unique place in the UK market.

While other manufacturers are drifting to ever-greater complexity, Intergas believes that simplicity leads to the reliability and efficiency that both customers and installers are looking for. If you’re wondering how they do this, then you’ve got your first reason to sign up to this course.

Open minded The one I attended was led by Technical Service Manager David Stanley, whose aim was to convince us to think differently when it comes to boiler design. Because Intergas is still a relatively new name on the British market – it started trading here in 2008 – David began the day with a brief look at the history of the company, which has more than 40 years manufacturing experience in the sector and has won the Dutch equivalent of the Which?

The five delegates on the course with me had a special interest in finding out how the boilers actually work and getting advice on

Trainer David Stanley focuses on the workings of the heat exchanger

how to sell them to customers new to the brand. To address these needs, David began with a look at the boiler’s streamlined design.

“One of the key benefits of our boilers is the small number of parts inside,” he told us. “The ones that are missing are the ones you change everyday. I did installation and breakdown work for over 12 years, and I was always swapping out plate heat exchangers, diverter valves, air pressure reducers, diaphragms, auto air vents. Our boilers don’t have any of those parts, which means there is so much less for you to worry about going wrong.”

David spent a good part of the morning explaining in detail how it’s possible to build a boiler without all these familiar parts, and the delegates with me were prompted to tell a few of their own tales of breakdown work.

The Technical Manger from one firm that looks after social housing contracts spoke of the significant expenses that are faced in London.

“The two things that you can count on failing are the plate-to-plate heat exchangers and the diverter valves,” he said. “One customer totted up the costings over a ten year cycle on a housing stock of around 20,000 homes and found they had spent over £100,000 on plate-to-plate and nearer £65,000 on diverter valves, just for those two components.”

Another delegate admitted that diverter valves were his company’s biggest consumable and that London was a ‘nightmare’ when it came to plate heat exchangers.

Double benefits

36_V2.indd 1

Intergas boilers do away with plate-to-plate exchangers by using its patented double heat exchanger, a key focus on the course. David showed us a short video that gave a good insight into how they are manufactured at the company’s factory in Holland before explaining the finer details of its operation. The exchange is made out of one aluminium moulding, with the copper pipe heating circuit and water coil completely integrated into the unit.

While that description will be easy enough for installers to grasp, it probably won’t mean much to your customers. However the ten year guarantee it comes with may well go far in convincing them that Intergas might be the right boiler for them. Since the first double heat

exchanger was sold in 1997, Intergas claims that not one has failed in its 18 year history.

The word ‘double’ crops up again later in the morning when David tells us about the boiler’s double condensation capability. He told us that Intergas is the only domestic boiler range that can condense in hot water mode as well as heating. This impressed an Operations Manager on the course who works for a large service and repair firm.

“I think the double heat exchanger is amazing – a really good idea and brilliant for the customer,” he told me. “If a customer has a problem with their combi’s hot water, they still have their heating, and vice versa.

There’s not another boiler that can do that.”

Fault finding The simple design of the boilers also avoids the nuisance of facing excessive fault codes. Part of the course is about familiarising yourself with the 19 (yes, that’s just 19) fault codes associated with its boilers. They cover less than half of one side of an A4 page and apply to the entire portfolio. One of the delegates on the course told me why he saw this as a big selling point for his company: “We are a major installer of one of the big British boiler brands, and the main complaint I hear from my engineers is the difficulty in diagnosing faults,” he told me. “They have to comb through pages and pages of codes to figure out what’s wrong, and even then there’s not always an obvious solution. We then have to get the manufacturer to send out their own service engineers to work on it, and it’s not unusual for them to spend loads of time getting to the bottom of it. I think switching over to Intergas will do a lot to cut down on all that wasted time for us.”

We also learn on the course that all the parameters are the same for any Intergas boiler being worked on. Added to that, parts are compatible across the range – so it’s one gas valve, one ignition module, one sensor, one circuit board, etc, for all Intergas boilers.

After a few short hours in the conference room, we moved on to the workshop, where three fully operational Intergas boilers are hanging on the wall. This gave the delegates a chance to roll up their sleeves and dig around

in the casings. By keeping class numbers small, everybody got a chance to spend plenty of time exploring the simple design.

Unanimous verdict At the end of the course, I had a chat with the delegates to find out what they thought of it. They all said they were impressed with what they learned. One of them, a Technical Director for a large firm, commented: “A lot of the boilers on the market are delicate, with lots of little components, lots of little sensors, lots of little probes, fragile wiring, which far too many installers find themselves replacing.

The Intergas range is a piece of engineering that cuts most of these bits out or right down to a minimum. It feels well-designed and durable, and I can understand when they say the reliability is there, because it’s built into the robustness of the components.”

Another delegate told me: “Today has been really good, because it helps our guys get comfortable fitting the boilers. I think the dual heat exchanger is fantastic – it’s brilliant for the customer and it’s a great selling point for us as a company. We can go to a customer and say, look, it’s got a ten year guarantee. That’s ten years worry-free. We are looking forward to progressing with this boiler.”

Speaking to one of the engineers on the course, who had just days before installed his first Intergas, he told me: “It was very easy to install. The only problem was with the jig. I couldn’t see at first how it worked, but once I figured it out, it just slid right in.

I was happy to have a chance today to work with the boilers in the workshop.”

38 Training & Education

A good investment in business Continuous training is the best way for installers to keep up-to-date with the latest innovations within the boiler industry. All installers can benefit from an education boost, as David Iszchak, Technical Trainer at Vokèra, explains.

T

here are many reasons why people take part in manufacturer training. From the surveys we have conducted with participants on our courses, the main reason installers take part in training is to update their knowledge. Out of the 486 people Vokèra has approached, 84% of installers stated that they wanted to increase knowledge, 15% said it was a company requirement, and less than 1% undertook training for legislative reasons.

In our view, training remains a fundamentally important part of how we can help make the installer’s life easier.

It’s essential for those who wish to keep up to speed with the latest gas boiler, renewable and control products on the market as well as the installation procedures and best practice, which can help them save time and money on site. Arguably, these factors are even more critical against the backdrop of a competitive market where the best will stand out from the rest.

Newly qualified?

Trainer David Iszchak draws on 30 years industry experience

Training can help installers compete in a crowded market

As you can see, our research shows that the vast majority of installers who attend Vokèra training come to update their knowledge and skills. Technology is constantly evolving and if installers stand still there is a real chance their knowledge and qualifications will become outdated.

Improving installation and commissioning competencies on particular appliances will ensure they are equipped to deliver the best customer service and advice, for example on boiler and flue location options together with information on ancillary energy saving controls which can reduce the homeowner’s fuel bills.

It is also important for those entering the industry to keep up to speed with their education. For newly qualified gas engineers coming from college, an apprenticeship, or fast-track course, Vokèra, has recently launched an informative new course to help make that transition into the practical world of work.

Modern boilers have been designed to be easily adaptable to many property types and can be installed without too much alteration or setting up by installers. However, it is

important that installers have an understanding about what is happening throughout the whole heating system and are able to offer homeowners advice and solutions about making the system more efficient and saving on costs. Run by Vokèra’s technical trainers, this course looks at:

experience for installers. Our view is that ‘we do not try to sell you boilers in these courses, they sell themselves’.

Instead, we focus on delivering real value for the engineer so they leave feeling completely confident about installing and attending products. In light of these ambitions, we’re delighted to report that 99.7% of attendees rate Vokèra courses as Good or Very Good. This is one statistic that we monitor very closely indeed to ensure that we continue to maintain the highest possible standards to our customers.

Radiator, system and pump considerations System design and constraints Fault-finding poorly performing systems Legislation Commissioning and Benchmark The wet side of a gas burning appliance The multi-meter

We’re confident that this new course will provide the perfect introduction for new starters in our industry and deliver real value. That, in essence, is the Vokèra training ethos.

Fully equipped Installer training should focus on the needs of the engineer, helping the installer become familiar with the product and be able to carry out quick and simple installation or repair. It should also be well-structured to ensure that installers can cover the key areas as efficiently and informatively as possible. This includes the different appliances themselves: installation, operation, wiring, flueing, Benchmark completion, fault finding and commissioning. A comfortable, fully equipped and modern training environment is also important, with top rate instructors capable of keeping installers engaged throughout the day, of course.

Although from our surveys legislation appears to be low on installers’ priority lists, the impact should never be underestimated. The Energy-related Products and Energy Labelling Directives will soon be taking effect and consequently Vokèra will be including an ErP module across all of its courses to ensure that installers understand their responsibilities under these European Directives.

Easy access Installers working across the UK and Ireland also need to have training facilities in locations that are near to them and are easy to get to. Vokèra has four training facilities in Bradford, Glasgow, London Colney and Callan, Co. Kilkenny as well as a number of satellite centres across the country. All the training courses on offer are run across the centres, and one-to-one sessions can be arranged at all venues.

HEATING Controls 41

Making the most of opportunities in 2016 Last year saw a significant growth in demand for smart heating controls and a growing number of installers looking to become a ‘connected specialist’. So where will 2016 take us?

Andy Mansfield, Marketing Communications Manager at Honeywell, shares his thoughts.

L

ast year was a landmark year for heating controls, as smart technology became an established part of the market. As much as that change is very much a result of ongoing advances in terms of the products available to the market, it’s an evolution that is equally being shaped by the demands of the customer.

The smart home – in which Andy Mansfield, Honeywell smart heating controls play a key role – is becoming an established part of the mainstream and is a trend that can only continue in 2016. Just like all progressive technologies, the idea of having a smart home is steadily moving from aspirational to accessible, as increased demand drives product choice up and costs down.

Growth in demand Demand has come from both the bottom up and the top down. The way in which we buy all of our services has changed beyond recognition in comparison to even ten years ago, with online research informing consumer choice just as much as the mass media – if not more so.

Meanwhile, consumers are seeing an exciting change in the way that mobile data is charged for. For example, some major providers are starting to offer value deals on 4G and access to wifi networks free of charge, stabilising access to apps and improving consumer confidence as a result.

At the same time, the Government has made a clear commitment to investing in smart technology as a way to encourage energy saving habits, like turning the heating down when away from home. The Chancellor announced a steady investment into the Internet of Things (IoT) in his 2015 Summer Budget, part of which has been brought to fruition via £10million of funding awarded to Manchester under a technology competition.

Raising the bar Evidently, the UK is currently leading a Europe-wide IoT movement. For example, in November last year, Professor Atta Badii, Director of the Intelligent Systems Research Laboratory of Reading University, spoke at a Brussels conference on the subject, pointing out that the IoT has the potential to raise the bar for more vulnerable users.

With a recent poll revealing that poorer over 65s have to choose between eating properly or putting the heating on because they cannot afford both, it’s an important point for now, and for the future. Our ageing population means that these groups within society will soon be less of a minority, with the concerns and issues that traditionally impact older people affecting us all. Here, we can expect smart controls to become increasingly important, empowering relatives and carers to manage vital services like the heating when they can’t be there in person.

Further progress However, while planning for a future society is important, the process of embedding the use of new technology into our communities starts now. As a result we can expect to see further developments when it comes to product functionality and user interface over the next 12 months.

41.indd 1

The user experience will continue to be a priority, both for manufacturers in designing controls and for installers when handing over to the householder. Ease of use and transparency are watch words for the whole industry. Energy efficiency will be a key theme for heating controls – as it always is – but with a heightened awareness.

First, the heating industry at large will seek to respond to the Government’s fifth carbon budget, compiled in line with the Paris Conference on Climate Change. Second, we can expect the industry to join forces with the Department of Energy and Climate Change to demonstrate the actual savings smart controls can deliver through robust research.

And third, we will see the requirements of ErP legislation bed in, as old stock works its way out of the system.

Support tools The energy efficiency labels that engineers must now provide when installing a boiler and a heating control should help to make the impact of modern controls easier to understand for both the specifier and the end user. With manufacturers providing a range of support tools and training to help, it will be interesting to see how professionals take ownership of the requirements into 2016.

And with the continuation of the smart heating controls phenomenon, the need to upskill won’t just be limited to ErP. Having seen the role of the installer begin to evolve over the last year or so, 2016 will signal the creation of a new raft of partnerships between heating engineers and

UK consumers want to get their hands on the latest controls

electricians as the two professions each get to grips with the technology and ways of working so they can both make the most of this serious growth area.

Be prepared With another freeze predicted by the Met Office for the early part of this year, we’re reminded once again that whether it’s early or late, a winter rush will come around.

So it’s important to ensure that staff are fully trained, using quieter times to invest in online courses, and stock up on entry level smart controls in order to upsell to customers replacing traditional dial controls.

While 2015 marked a turning point for the heating industry, 2016 promises to take us further down the road of smart savings. As more consumers become open to the advantages of modern heating controls, installers and heating engineers who invest in the right training will have the chance to reap the rewards of an increasingly lucrative business opportunity. www.honeywell.com

Online calculator for energy labels Installers looking to improve their ability to create, print or provide ErP energy labels for their customers may be interested to learn about Honeywell’s new web-based calculator.

The calculator has been developed in response to the new requirement for engineers to supply an ErP energy label when installing a package of heating components, which commonly comprises a boiler and hot water cylinder and/ or heating controls.

Under the legislation, heating controls can form part of a package when they are fitted alongside a space heater or combi heater.

The online tool enables installers to create a package label by choosing from any of the Honeywell heating controls, while inputting the energy efficiency information from the space or combi heater in question. It will also allow the creation of

zone thermostat being rated in the most energy efficient category, delivering an additional 5% saving.

Easy to use The mobile friendly website (erplabel.honeywell.com) is easy to access from any internet-enabled device.

It is designed to be user friendly – once a label has been generated installers can choose to either download it as an image, or email the

label to their customers and/or themselves. At the same time, the calculator is programmed to load the last label from the last session, helping to cut down on time duplicating similar jobs. The user does not need to create any accounts or store any personal data.

Andy Mansfield, Marketing Communications Manager at Honeywell, comments: “ErP is an important milestone for the heating industry as we look to reduce carbon emissions and deliver savings for customers.

“However, the legislation places an additional responsibility on the installer, who is now required to supply a package energy label. We want to help make that process as straightforward as possible, and hope that installers across the country will find our online tool is a big help in meeting the new standards.”

42 HEATING Controls

Easy way to slash heating bills Millions of UK households don’t have effective heating controls which means they are missing out on savings on their heating bills. That’s the view of Bjorn Sejr Nielsen of Danfoss, who looks at how modern controls can cut energy costs and the technology driving new developments.

G

overnment figures indicate that of the 95% of UK homes with boilers, 800,000 have no heating controls at all and over 70% lack the minimum specified by Building Regulations. The central heating system uses by far the most energy in a typical home and that is reflected in energy bills.

The energy saving potential of fitting modern Bjorn Sejr Nielsen, Business heating controls is supported Development Director by research conducted at Salford University’s Energy House. This showed that heating systems with controls cost 40% less to run than those without. It is not surprising, therefore, that heating controls are now recognised as one of the ‘big three’ measures, along with insulation and new boilers, for making a home more energy efficient. Installing and using heating controls correctly ensures that no heat is wasted by keeping some rooms warmer than they need to be. As a result the boiler operates more efficiently and uses less energy to maintain a comfortable temperature where required.

Having the heating on for short periods at a time is seen by some as a means of saving money. However, boilers are at their least efficient in the first hour or so of operation, so this can be a false economy. As long as suitable controls are installed it can be much more beneficial to leave the heating on for a longer period when it will use less energy to maintain comfortable temperatures.

Targeting TRVs So what controls are required to achieve optimum heating efficiency? According to the tests carried out by Salford University, a property should be fitted with a room thermostat and a full set of thermostatic radiator valves (TRVs). The research highlighted the importance of TRVs to provide independent temperature control in every room to ensure satisfactory heat distribution around a

dwelling. Indeed, the tests showed that this is not achieved without TRVs, even if a system is balanced. TRVs are quick and easy to install to existing radiators with no wiring required. Unlike a manual radiator valve, a TRV will adjust the heat output of the individual radiator to maintain a comfortable temperature. It will even turn the radiator off in response to an increase in ambient temperature, such as sunshine entering a room. And in rooms that aren’t used very often, the TRV can be kept at a low setting, providing background heating to save money. It can then be turned up when the room needs to be warmer.

Remote control

So-called smart technology, found in popular devices such as phones and tablets, is now driving the development of smart heating systems which give consumers even greater control over their energy consumption. Even what might be described as very basic on/off controls have ‘smart’ features such as digital touch-screen displays and “A property should be fitted with a room micro-processor controlled Good timing programming for enhanced thermostat and a full set of TRVs” functionality and efficiency.

In addition to temperature Also, the wider use of control in each room, it’s important to install a timer to set the overall on and wireless products in the home is increasing demand for off times. In addition to basic timers there are now wireless heating controls. Battery-powered digital room ‘programmable’ versions which give more flexibility thermostats bring benefits for installers and users alike, such as allowing householders to set different times for being both easy to use and to install, with minimal wiring weekdays and weekends.

the requested temperature, rather than simply turn the boiler on or off. This help to save energy, increase comfort and prolonging the life of a heating system.

Another new feature is the Farsight software feature, which automatically displays the target temperature or time when movement is sensed across the room. The thermostat can be set to display target temperature, an analog clock or digital clock, or to turn Farsight off.

There is also a new stand for the Nest Thermostat.

It was designed for homes that don’t already have a thermostat, or where the old

thermostat was in a room where the temperature wasn’t regulated, so it can be put in the best place to sense the temperature and activity in the home.

“With new software and hardware, customers can save more whilst staying comfortable, thanks to remote hot water control and OpenTherm compatibility,” says Lionel Paillet, General Manager of Europe for Nest.

“The 3rd generation Nest Thermostat will be available through thousands of retail locations, professional distributors, and directly through Nest Pro installers.”

Smart technology is now being taken to the next level with a variety of smart thermostats which allow consumers to manage the temperature in their home – and therefore their energy costs – anytime, anywhere using a heating app. Consumers can also adjust their smart thermostat’s time and temperature settings remotely while they are out at work, for example, or if they are going to be home later than planned so they don’t waste energy heating an empty house.

Although smart technology clearly has a part to play in future products, at Danfoss we believe it shouldn’t be the main driver of new developments. Creating controls that bring real benefits for consumers, such as ease of use and convenience, have to be the primary focus. From our experience, a combination of TRVs and dial room thermostat will meet the needs, and budgets, of most consumers. What’s important is getting the message across to all those households without effective heating controls that there is a simple and cost-effective way to keep their home comfortably and affordably warm.

Is smart always the best decision?

With the number of ‘smart’ heating controls on the rise, specifying the right model can be a bit of a minefield. Martyn Bridges, Director of Marketing and Technical support at Worcester, looks at some of the benefits and drawbacks of this technology.

T

he market has been subject to an influx of heating controls of late, offering homeowners a plethora of ways to customise the operation of their heating systems in the hope that this will lead to an increase in comfort and efficiency. With most of these devices able to connect to the internet, it has become common for us to identify them as ‘smart’, almost regardless of how the device itself performs.

is really the problem. This would leave the end user frustrated with a system that doesn’t work whilst the control manufacturer has to resolve the situation – probably in conjunction with the installer.

More condensing

Smart or not?

While being able to control heating from afar is undoubtedly a useful facility, it’s worth noting that saving money as a result of this technology is not necessarily guaranteed.

For example, homeowners who happen to be leaving work earlier than normal – and therefore turn the heating on remotely in readiness for their return home – will actually be using more energy than someone who doesn’t have remote access.

Quite rightly, this has brought many to question whether internet connectivity is indeed enough to merit a control being labelled ‘smart’. Installers would be well-advised to adopt a more demanding set of criteria when deciding whether a heating control is right for your customer.

This recent flood of heating

controls to the market has brought with it a growing presence of boiler plug-in heating controls that are not designed or marketed by the boiler manufacturer. However, there are certain considerations for heating engineers to make when deciding whether these ‘copycat’ controls are worth what is often a lower price tag.

Call out concerns Before any purchase, installers should not only check that the control fully complies with the requirements of the CE mark and EMC Directive, but they should also look closely at the small print on the boiler and the control warranty.

This is because if a call-out is needed during the warranty period of the boiler and a third party controller is found to be at fault, then the boiler manufacturer will not cover this controller under warranty. This leaves the problem of who is going to repair or replace the controller that is at fault. Given that, in most instances, the controls manufacturers do not have a field service department, it is likely that the installer would incur the extra cost of having to replace the controller in this instance.

Similarly, there could also be a situation where the boiler manufacturer gets called out under the belief there is a boiler issue, but finds that a third party controller

Another prime consideration should be whether the unit ensures that the boiler condenses as much as possible even without intervention from the end user, or if it simply supplies an on/off control.

The very best controls will use advanced features to make sure a boiler condenses as much as possible. For example, those with load compensating technology take into account the actual room temperature and only fire the boiler at the necessary temperature level to achieve the desired air temperature.

This ensures a more efficient use of fuel, maintaining peak efficiency levels while still achieving the desired room temperatures.

Meanwhile, weather compensation boosts efficiency even further by referencing the property’s postcode to determine local weather conditions.

The introduction of the Energyrelated Products (ErP) Directive has made it much easier for installers to discuss the potential benefits of

various heating controls, bringing with them a new classification depending on the category each device falls under. For example, the use of weather and load compensation, such as that used by Worcester’s Wave Smart Thermostat, will add a 4% uplift in energy efficiency to a heating system, allowing installers to very simply achieve a 98% (or A+) rating when installed with a high efficiency boiler.

There are clearly a whole host of factors heating engineers should be at least mindful of when they come to making controls recommendations to their customers. In the longer term, it would be great to see everybody in the industry come to think of a truly ‘smart’ device in the context of something which increases the efficiency and effectiveness of a heating system, rather than simply increasing the interaction needed from the end-user.

Making the most of smarter technology The market for smart heating controls continues to grow, but how can you be sure that you are recommending the best solution for your customer? Paul Hughes, Communications Manager at Tado°, highlights some of the key features and benefits to look out for.

T

here are two things we can be sure of in the coming months – temperatures will drop and energy bills aren’t getting any cheaper. The average annual dual-fuel bill, covering gas and electricity, is now over £1250 compared to just £475 ten years ago. This has hit consumers hard, but it has also driven innovation in energy-saving technology and helped encourage a change in user behaviour.

Heating controls have played an increasingly important role in reducing energy use without sacrificing on comfort. The smart thermostat market in particular has grown exponentially over the last few years in features, functionality and user numbers. Smart thermostats are driving the home automation sector, demonstrating real value and savings, while increasingly being able to communicate with other smart home devices such as locks and lights for user convenience and comfort. Today hundreds of thousands of Brits have already switched to a smart thermostat and the figure is set to soon grow to over 500,000 a year.

Spoilt for choice There are already many smart thermostat devices from various manufacturers that allow residents to control their thermostats remotely through their smartphone and each have their own features and benefits. For the homeowner/renter who is looking to smarten up their heating system and save more this winter, the choices may seem daunting. But there are some key questions worth considering which will help them find the right smart thermostat for their home: • Is it compatible with my heating system?

• Does it have hot water control?

• Can it control digital interfaces?

• Is it easy to use?

• What are the features and benefits?

• How much can it save a year?

There is a wide range of heating systems on the market and these will determine what kind of smart thermostat is compatible. Whether a home is fitted with a combi, system and heat-only boiler, conventional and condensing boiler, zoned system, hydronic and electric underfloor system or a heat pump will play a role. The ability to control hot

Usability With all of these features and technology it’s important to keep the interface and controls simple for the user. Many residents are not tech savvy and shouldn’t be expected to learn. Therefore smart thermostats have been made for non-techies, with apps and control systems designed to be as user-friendly as possible. This hasn’t come at the expense of design and aesthetics. From the bright and bold to the subtle blend-into-the-background devices, smart thermostats come in many shapes and sizes and it’s up to each user to decide what suits them and their home.

Apps and control systems are as user-friendly as possible Smart thermostats have a wide range of features and water is another factor worth considering as several smart benefits depending on the manufacturer. The first key feature thermostats do not have this functionality as they lack a shared by all smart thermostats is the ability to control home digital (BUS) connection and dual relay. heating remotely through a smartphone, tablet or computer, Some smart thermostats are also modulating controls, but from thereon in the differences between devices begins which means they have the ability to precisely control to vary.

Leading smart thermostat manufacturers have approached this issue primarily with two differing solutions – through learning or geolocation features. A learning smart thermostat programs itself by learning your behaviour patterns and desired temperatures for certain days and times during the week, and then building a schedule for your heating system. Whereas geolocation-focused smart thermostats use your phone’s location to automatically turn the heating off or down when you leave home and to pre-heat it to your desired temperature when it senses you returning home. Annual energy savings range from an average of between 10 - 30% when upgrading to a smart thermostat, which represents a saving of between £125 to £375 a year on a dual fuel bill.

Taking a step forward with TPI Upgrading central heating controls is one of the easiest ways to help householders reduce their fuel bills, but TPI (Time, Proportional and Integral) technology can achieve even greater savings. James Palmer, Marketing Manager at Horstmann Controls, explains more.

T

he Green Deal has been put to rest by the Government, citing poor take-up as the primary reason. Launched in 2013, the goal was to encourage landlords and homeowners to implement energy efficient measures that would reduce their fuel bills and cut their carbon output. The Green Deal scheme was scrapped last July and branded a failure.

However, homeowners still have the opportunity to reduce annual heating bills by upgrading their central heating controls in a costefficient way.

Two summers ago, BEAMA produced some statistics that claimed householders could save 40% on their heating bills by installing an effective controls package.

This comprised a room

TPI technology

James Palmer, Horstmann

thermostat, TRVs on the radiators and a timer – ideally fitted to a condensing boiler.

A year later, after further analysis, BEAMA came back with a revised figure, now claiming savings of 53%. This revised figure was achieved by refining the stat specification to a modern TPI model that yields higher savings.

BEAMA’s savings figures are calculated from data collected from the Energy House, a model home based on a typical 1900s era end-terrace two-bedroom property fitted with a gas boiler and TPI controls. The house is contained within an environmentally controlled chamber at the University of Salford, which allows a real-world measurement of the performance of heating systems under controlled conditions.

The independent findings relating to cost savings from controls open up a range of possibilities for householders to create energy saving opportunities while increasing the efficiency of their home heating.

While radiator TRVs are

widely accepted, Government figures confirm that this is certainly not the case with room stats. Yet modern wireless technology allows for simple installation with the minimum of decor disruption, and the latest TPI room thermostats feature software capable of adjusting the temperature to maintain a consistent room temperature.

TPI outperforms traditional types of thermostat (bellows or mechanical) by calculating set temperature ‘cycles’ that the heating system will go through per hour and also by optimising the boiler firing regime.

This ensures it fires for shorter durations as the room temperature approaches the set point, preventing the over-use of

the boiler and eliminating wasteful temperature ‘over runs’. This creates the potential for energy savings in the order of 32% from the thermostat alone when used with condensing boilers.

Quick payback At Horstmann we have long recognised that TPI is the way forward and as such we’ve developed a family of room thermostats based on the technology. Combining functionality and a smart clean design, they are equally suited to replacement and upgrade installations as well as new build.

The thermostats offer versions covering RF to mains or battery powered options.

Wireless and battery powered versions have digital displays; the mains version has a

conventional dial setting, and there are tamperproof and frost protect variants.

Considering the cost of installation and equipment, the payback on such an upgrade should be achieved within a year.

In the absence of the Green Deal or any replacement initiative, opportunities for installers to take the initiative to help householders save money are always welcome.

It is worth remembering that a controls upgrade is by far the quickest path to achieving cost savings and significant reductions in the carbon emissions from existing homes. In tandem with correct levels of insulation it is an option well worth considering.

WHat’s New 49 Heat pumps to meet Slimline model saves space new build demand The new 4kW Ecodan air source heat pump from Mitsubishi has been designed to tackle the needs of newbuild homes, where a reduction in fabric U-values and thermal bridging means that the requirement for hot water is likely to exceed demand for heating.

The new Ecodan QUHZ monobloc system delivers water at 70ºC to a packaged 200 litre thermal store. From this thermal store, mains water is heated directly up to 65ºC via a plate heat exchanger to deliver hot water on demand.

“This model uses CO2 as a refrigerant to ensure a large delta T between the flow and return temperatures to and from the outdoor unit,” explains Mitsubishi’s technical expert Jordan Jeewood. “This delivers the high levels of efficiency that enable the system to meet the high hot water, low heating requirements of today’s newbuild properties.”

Designed for homes where space for a hot water storage cylinder is limited, the new Megaflo Eco Slimline from Heatrae Sadia is set to be the latest addition to the company’s unvented cylinder range.

Being taller, the new space saving cylinder stores the same amount of hot water as an equivalent capacity standard cylinder. The Eco Slimline also features an internal expansion system to ensure a neater installation.

The cylinder is available in both direct and indirect versions and in capacities from 100 to 190 litres.

Jon Cockburn, Head of Marketing, says: “Our homes are undoubtedly getting smaller. The Royal Institute of British Architects (RIBA) suggests the average UK new home is now 76m² – half the size of the houses built in the 1920s. So, with space at a premium, finding an adequate amount of room for a hot water storage cylinder

can be problematic, even in older properties.

“In line with our strategy to continually evolve the Megaflo Eco range to meet market needs, we identified a demand for a slimmer version to fit into non-standard sized airing cupboards and other compact storage areas.”

The Eco Slimline’s internal cylinder will have a lifetime warranty, which includes onsite parts and labour. It will be available from April.

Responding to demand for the more flexible location of WC flushing systems, Geberit has launched a new system that will enable flush buttons to be located up to 1.7 metres from the toilet.

The company says that research has revealed that as many as 30% of users would prefer to site the flush to the left or right of the WC, rather than directly behind it. Almost as many people again are keen on the idea of siting it by the bathroom door, ready for flushing on their way out.

Find the source of leaks The new MR176 Imaging Moisture Meter Plus with IGM (Infrared Guided Measurement) technology makes it easy to find the source of a water leak or moisture ingress.

The meter with built-in thermal imager shows the user exactly where to measure, providing all the measurement capabilities needed for fast troubleshooting, ensuring the true nature of the problem can be established before remedial action is taken.

Easy to use, the moisture meter can also be a valuable asset during the drying process.

A quick thermal scan with the instrument will show where the evaporation process isn’t up to speed. Adjustments to blower and dehumidification equipment can then be made.

Images can be downloaded and shared so they can be reviewed, analysed and used to create reports with a free software package. Compatible probe accessories are also available to facilitate measurements in difficult spots.

New duct size The Ductmaster Thermal range by Nuaire has been enhanced with the addition of a 220 x 90mm duct size, offering greater efficiency in low profile spaces. It provides an airtight seal formed by the connectors, negating the requirement for more sealant or tape on installations.

The low profile nature of the 220 x 90mm option means it is suitable for applications with restricted void spaces whilst maintaining a high capacity of air flow for the installation. The higher air flow capacity means less air resistance and consequently puts lower pressure on units. Lower pressure means less noise from the system. www.nuaire.co.uk

Technical Tips HEAT INTERFACE UNITS The use of centralised plant to deliver heating and hot water via heat interface units (HIUs) in multi dwelling developments is increasingly common. Jon Cockburn, Head of Marketing at Heatrae Sadia, answers some frequently asked questions about HIUs. What is an HIU? HIUs provide heating, and sometimes domestic hot water, to individual properties within a multi dwelling development (such as a block of flats or apartments, or a larger district heating scheme) served by centralised heating plant. They are sometimes called ‘heat boxes’.

What is district and community heating?

District heating supplies heat from a central source to several buildings – which might include houses, apartments, offices, schools, shops and community centres.

The heat is delivered through a network of pipes carrying hot water. Community and communal heating systems follow the same principle, but on a smaller scale – sometimes serving a single block of residential flats or apartments.

Why are HIUs used in these schemes?

HIUs mean that property managers can record the amount consumed by an individual household using a meter, making them very attractive for councils and those operating a large portfolio of buildings. Meter readings can even be carried out remotely, making HIUs a much more viable option. Metering can also be a positive incentive for occupants trying to lower their energy consumption.

Meanwhile, a controller monitors and regulates the heating and hot water system in order to optimise performance, working with the room thermostat.

Where are HIUs installed?

They can be installed within each individual dwelling, or in the dividing wall between each dwelling and the ‘landlord’ space – the latter providing easy access for inspection and maintenance.

Other pluses for landlords include a first fix rail, meaning that installers can minimise risk of damage or theft by completing the installation of the interface unit only at property handover.

What are the main benefits?

With traditional systems, annual gas safety checks mean that any gas appliance poses a never ending challenge for landlords, who are dependent on tenants providing access to their properties. The use of HIUs removes the need to conduct a gas check on the heating system – and, if there are no other gas appliances in the affected

properties, could negate the need for individual gas checks completely. The time and costs involved with boiler servicing and maintenance is also significantly reduced.

It also reduces the problems associated with supplying gas to multi dwelling buildings, decreasing the risks linked to gas distribution pipework and saving costs, and eliminates the need to fit numerous flue terminals/condensate drainage systems. The capital installation and whole life costs are therefore also reduced.

The incorporation of low carbon or renewable technologies can also be simpler and more achievable, as it can be difficult to incorporate these technologies into individual properties in a multi occupancy scheme – helping designers and specifiers to meet ‘zero carbon’ targets. While the government has recently announced the scrapping of zero carbon targets for 2016, developers will still have to meet zero carbon requirements set by the EU in 2019.

The diverse thermal loads offered by multi-occupancy accommodation also presents an attractive demand profile against which such technologies can be operated to maximise the benefits.

How are HIUs regulated for safety?

While the Electrical Safety Council recommends PAT testing to ensure that landlord supplied appliances are safe at the point of letting, the HIU wouldn’t be included as it doesn’t fall under the definition of a portable appliance.

Therefore, to ensure electrical safety, installers and their customers should look to independent third party approvals of the HIU in order to be sure that they comply with electrical industry standards and regulations. For example, the NEMKO mark demonstrates that the product has been assessed for conformity to electrical safety legislation by a competent body.

Equally, independent testing for water fittings ensures that products are suitable for potable water use, guaranteeing that they are safe to use and will guard against contaminating potable water supplies.

Here, the industry standard third party certification is provided by WRAS or KIWA. For more information, please visit the website: www.heatraesaida.com

Making it easier to insulate pipework, right up to the zone valve, new insulation shells from Honeywell are specially moulded to fit around the zone valve body, adding extra insulation and combating transmission losses.

An easy-fit design means no tools or tape are required, and the shells can be fitted to an already-installed zone valve.

The insulation foam can be trimmed to fit.

Insulating pipework and valves helps to keep the heat in the pipes, and guards against wasteful heating of voids and frost

in unheated spaces, according to Andy Mansfield, Marketing Manager. He says: “These shells make it much easier to insulate primary and domestic hot water pipework, as required in Part L Building Regulations.

It’s all part and parcel of our mission to give a helping hand to installers while giving householders control over their heating and energy bills.”

Burns both logs and pellets Suitable for both the domestic and light commercial markets, the MHS-approved, duel-fuel Herz Pelletfire boiler is capable of burning logs and wood pellets.

The compact Pelletfire range comes in a range of output options from 20 to 40kW and offers flexible heating with separate combustion chambers.

The two fuels can be switched between easily and the operation can be set up to automatically transition to wood pellets if all logs are burnt out.

Combining these two technologies brings out the

best of both – with users able to benefit from the flexibility and cost savings from log burning and the reliability of a continual fuel feed system

from wood pellets. The Pelletfire is compatible with various types of pellet stores including the traditional V profile and modular pellet silos. It also incorporates the T-Control touch system, making operation of the boiler user-friendly.

The smooth running of the boiler is also helped by the Lambda probe control and automatic cleaning capabilities of the heat exchanger and combustion grate, ensuring the cleanest combustion and maximum heat transfer.

Having received the Quiet Mark for its mains booster pump, Salamander has gone one step further to tackle noise issues with the introduction of a pump mat to further reduce noise from underneath.

The mat, made from high density foam, effectively reduces the transmission of vibration, and therefore noise, radiated by the pump. It could help to reduce vibration in areas where a pump can often seem nosier, such as when PHAM ad - Page Tabloid placed on hollow materials
