Survey highlights extent of CO risks in the home

As the industry looks to back CO Awareness week, research conducted by CORGI HomePlan suggests that one in ten adults have experienced some degree of carbon monoxide poisoning in their home. According to recent research conducted by CORGI HomePlan, one in ten adults in Britain have experienced carbon monoxide poisoning to some degree and a further one in 11 are aware of someone who has been poisoned. The Dunfermline based company hopes that the research will encourage people to take action as only 47% of households have a carbon monoxide alarm installed in their homes and less than half (42%) say that they have their boilers serviced regularly. The survey of 2000 homeowners also reveals that a shocking 33% do not even know that boilers are a potential source of carbon monoxide. The breakdown and repair business is appealing to its 5000 strong network of heating engineers and the wider industry to share their knowledge of the dangers in order to help protect homes over the colder months. Kevin Treanor, Director of CORGI HomePlan, says: “Awareness among the general public is still very low and the reality is exposure, even at a low level, can lead to life-changing

health problems. As engineers, we all know that regular servicing of all gas appliances and installing a carbon monoxide alarm will vastly increase the safety and protection of people’s homes and it’s up to the industry to help educate people.” As part of its campaign to help raise awareness, CORGI HomePlan is giving away free CO alarms to the public via its website, whilst stocks last, and has produced a guide to protecting homes from carbon monoxide.

This month sees the 10th National Carbon Awareness Week (16-22 November) which aims to highlight the importance of taking care of heating appliances in the home. The campaign has received the backing of a number of manufacturers, including Ideal Boilers which is offering installers the opportunity to get co-branded leaflets and win CO alarms throughout the week. “Customer safety is of utmost importance to us,” says Customer Service Director Chris Jessop, “and ensuring installers have access to relevant information is key to ensuring their customers understand the importance of maintaining gas safety.” As the voice of the oil heating sector, OFTEC is urging all households using oil heating to install CO detectors and ensure their boiler is regularly serviced and inspected by a registered technician. “Whilst homes with oil heating have a strong safety record, homeowners still need to be aware of the dangers,” says OFTEC Marketing Manager Malcolm Farrow.

New research commissioned by the Bathroom Manufacturers Association (BMA) into water usage in England supports the aims of the European Water Label (EWL) Scheme, which is calling for strong incentives to replace the older plumbing products currently installed in existing properties. The research shows that 44% of England’s houses still have toilets that flush with 7.5 litres or more. Since the latest toilet models flush with a maximum of 4 litres, it follows that 10 million of the houses in England use nearly twice as much water as they need to. The research concludes that if the existing water-wasting toilets were replaced, there is a potential to save at least 644 million litres of water per day in England alone.

Members of the Labelling Scheme believe that a major reduction in water consumption can be achieved throughout Europe if householders were incentivised with a cash payout to replace their old water guzzlers. Scheme members point to a similar scheme to replace old central heating boilers a few years ago, which proved a success. EWL is urging the European Commission to develop and implement a robust Europeanwide scheme to deliver monetary incentives to encourage both householders and businesses to purchase replacement water-efficient toilets, showers, bathroom and kitchen taps, faucets, and other plumbing products. Yvonne Orgill, MD of the European Water

Labelling Scheme, says: “There have been tremendous advancements in the technology and efficacy of plumbing products during the last five years. And just as you wouldn’t use a 20-year-old mobile phone, it doesn’t make sense to use a 20-year-old bathroom. The industry is playing its part in the drive for water and energy efficiency. Let’s hope the EU will play its part too and create the incentives.” Peter Manning, Technical Liaison Manager at Bristan, adds: “We ask all plumbers to continue to encourage water-saving among their customers and recommend the latest and most effective water-efficient products available. That way, they can help to raise the standards of water efficiency in the UK.”

vulnerable to late Viewpoint payment issues by Chris Jones

Heating contractors and other small businesses continue to face a financial challenge because of late payments. According to the payment software company, Tungsten, one in four small businesses operating in the UK construction sector have said that slow payments have put them at significant risk. Research has revealed that 42% of firms felt that the situation had not improved in the past 12 months and 32% suggested that it had deteriorated. Only 26% of those questioned thought that late payments posed less of a problem than 12 months ago. The research follows a series of measures instigated by the Government, including a payment charter for the industry which saw major contractors, clients and the Government commit to paying suppliers within 30 days from 2018. Despite the scale of the problem, just 22% of respondents had heard of the Prompt Payment Code, a voluntary scheme launched in 2008 to help raise standards in payment processing in the UK. The same survey also revealed that 70% of small

Getting the message across

businesses are likely to turn to their bank first when experiencing cash flow problems, while just 14% consult alternative sources of funding. “While all small businesses experience lean months, construction firms are especially vulnerable to cash flow problems as the industry often sees sudden spikes in demand.” Earlier this year, Tungsten undertook research that showed the average SME (small to medium enterprise) is owed £40,857 in unpaid invoices and £20,937 of that is overdue. The Federation of Small Businesses, which represents small firms in the UK, has said that late payments is one of the top 10 issues that small firms will face over the next five years.

The month of November will see the annual CO Carbon Monoxide Awareness Week run for the tenth time, but a new survey suggests that previous campaigns could not have made much of an impact on the British public (see front cover story). Apparently, 33% of householders would be surprised to learn that their boiler could be a potential source of CO leakage and more than half the population don’t consider it a high priority to ensure that their boiler receives a regular service. Despite the ongoing publicity surrounding how Thomas Cook mishandled the tragic deaths of two young children in Corfu, and many other incidents closer to home, it seems that large sections of the public remain blissfully unaware of potential dangers from poorly maintained heating appliances. For those who work within the heating industry it might be tempting to assume that there is a receptive audience for any communication about CO safety, but one thing the CORGI HomePlan survey highlights is that there is little room for complacency. It is now a legal responsibility for landlords to install CO alarms in rented properties, so surely there is a good case for extending this to all households. There is no denying that there is an element of self-interest from companies who want to promote the importance of regular boiler maintenance and manufacturers of CO alarms, so it’s important that those voices without a product or service to sell – the charities representing the victims of CO poisoning – continue to get their voices heard. It can only be hoped that it won’t take another domestic tragedy before the message starts to hit home. Follow us on MV_Fluids_qtr_A3_Aug05

Remember to notify oil installations OFTEC is urging all installers to ensure their work is correctly notified, as failing to do so could be a breach of their duty of care. With the number of appliances sold each year higher than the number actually notified, it’s clear not all installers are taking their responsibility to notify work seriously. The oil heating body points out that if an installation isn’t notified, it’s actually the homeowner who has broken the law, not the installer. But with so many homeowners unaware of the regulations, OFTEC says installers must

Money for Marie

Boiler manufacturer Baxi is on track to meet its fundraising target for Marie Curie – its national charity partner for the second year running. Baxi has pledged to match the success of last year’s campaign target by raising another £50,000 for the charity by the end of December. Fundraising events have included a sponsored walk across Hadrian’s Wall, a night time cycle around London, a Mud Run, 75 mile cycle around the Lake District, a 24-hour computer gaming marathon, and Baxi’s very own version of the Great British Bake Off, as well as many individual achievements such as marathons and raft races. So far, Baxi employees have raised nearly £48,000 for the charity. Fundraising efforts will continue to the end of this year.

Director Adrian Lightwood says: “Many homeowners are blissfully ignorant of the need to notify and it’s often only when they come to sell their property and the buyer’s solicitor asks to see the documents that the true situation is revealed. “Homeowners are then faced with having to track down the original installer to seek a retrospective regularisation order from the local authority for the unauthorised work, or take out indemnity insurance against contraventions of Building Regulations for the

Homeowners fear boiler breakdowns Nearly a third of homeowners fear boiler breakdown this winter according to a survey by Gocompare.com, and many will be left struggling to pay for the cost of repairs. The survey also found that 43% of homeowners have experienced boiler problems in the last three years, paying out on average £344 for repairs. Almost one in ten (9%) faced bills in excess of £1000. While 56% said their boiler only needed minor repairs, 20% experienced a major breakdown and another fifth needed to have a new boiler installed. When asked how they might pay a £300 repair bill if their boiler broke down this winter, only 34% of homeowners surveyed said that they had money set aside for such an emergency, while 11% would have to pay

by credit card. Less than a third (31%) have specific boiler cover. Homeowners may have cover for emergency boiler or central heating repairs under their home buildings insurance. Gocompare.com reviewed over 360 home buildings insurance policies and found that the majority (72%) provide cover for home emergencies as either a standard feature (18%), or as an optional cover for which an additional fee is payable (54%). Of those policies providing cover for home emergencies, 98% cover the home’s main central heating system and 86% provide insurance against hot water failure. The level of cover varies from policy to policy, but the majority (90%) will pay out £500 to £1000 for each emergency.

Removing the need to involve a local authority saves both time and money, benefitting the installer and customer alike. Adrian concludes: “OFTEC registration is all about providing homeowners with the reassurance that technicians are fully competent to carry out work and can be trusted.”

Beware of copycat Life Award winners make a difference heating controls Boiler manufacturer Worcester has raised concerns about the growing presence of non-accredited heating controls appearing on the market. Martyn Bridges, Director of Marketing and Technical Support, says that the lack of legal guarantees on controls not recognised by manufacturers could mean homeowners who fit them could have problems in the long term. He advises that installers take a number of factors into consideration when choosing a control. “Installers should read the small print on the boiler warranty,” says Martyn. “If a call-out is needed during the warranty period and a third party controller is found to be at fault, then it is important to be aware that the boiler manufacturer will not cover this controller under warranty. It is therefore going to be the installer who incurs the extra cost of having to replace the controller because, at best, all they will get from the controls manufacturer is a replacement, which of course the installer will then have to go back and fit.” Martyn also argues that the new ErP regulations should come into the thoughts of installers when they come to recommend

and install heating controls. He says it’s important to ensure controls fully interact with the boiler’s interface. “The question must be asked whether unofficial controllers will be rewarded with an uplift in efficiency in the same way as a recognised control,” adds Martyn. “Does the unit ensure that the boiler condenses as much as possible even without intervention from the end user, or is it simply an on/ off control offering a 1% or, at best, 2% system efficiency uplift? “In an age of increased risk of data theft, installers would also do well to make sure that any usage patterns collected by a controller are safe within the device,” concludes Martyn.

Over £40,000 has been given in charitable donations by training and certification provider BPEC to projects that use plumbing skills to enhance the lives of others less fortunate, both in the UK and abroad. At its fourth Life Award ceremony, held at Derbyshire County Cricket Club, the BPEC Charity made three awards to deserving projects. Three other projects were supported via the organisation’s ‘Legacy Fund’ that ensures projects supported by BPEC are sustainable over the long term. The BPEC Charity Life Award 2015 was presented to Emily Gait and Stephanie Moore from Pump Aid

for a project to build 10 new Elephant pumps in 10 communities in rural Malawi. The award of £15,000 will provide clean and safe drinking water for over 1000 people. The funding will also assist in the delivery of health

holidays, Formula 1 tickets, gift cards, tools, workwear and branded merchandise. The Scan and Win promotion can be accessed through the Plumbing Toolbox app, which also enables installers to register product warranties and submit Gas Safe notifications on the job. To join Club Energy and take part in Scan and Win, please visit the website: www.glow-worm.co.uk

MCS alternative A new scheme has been announced by the HHIC and BEAMA that is designed to act as an affordable alternative to the current Microgeneration Certification Scheme (MCS). The programme is based on the Competent Person Schemes (CPS) and TrustMark and aims to ensure that a quality service is delivered to the consumer, but at a fair price to the installer. It is expected to launch early next year. The potential cost saving for installers using CPS and TrustMark as an equivalent scheme to MCS and a suitable Consumer Code is between £1500 and £2000, based on 30 notifiable jobs a year, two year warranty and 10 employees. Isaac Occhipinti, HHIC’s Head of External Affairs, comments: “HHIC has long been a critic of MCS as it is too bureaucratic and expensive, but with Government support for microgeneration technologies waning, we believe that an alternative is needed to keep interest in the renewables market alive and protect quality and consumers.”

New research commissioned by Toolstation reveals that almost half of Brits switch on the central heating whenever they feel chilly, no matter what time of year it is. The survey also showed that 9% won’t put the heating on until November, no matter how cold it gets, and 27% of Brits wait until putting on a jumper is not enough. Despite stereotypes of ‘tough Northerners’, the research revealed that it’s actually Londoners and those in the South West who are hardiest, with just 38% turning on the heating whenever they feel chilly, compared to 55% in the North East and North West, and 60% in Scotland.

It was also found that the thermostat can cause discord at home, as 46% of Brits argue with their partners or housemates over the heating – with 29% experiencing actual ‘marital strife’. Meanwhile, 21% have had ‘constant disagreements’ about the thermostat, with 14% actually moving out. John Meaden, Director of Marketing at Toolstation, comments: “We conducted this survey to gain more understanding about homeowners’ behaviour and attitude towards central heating and we were certainly surprised by the results. It seems for most Brits, the heating is already on.”

10 News Review SMEs need to get Plumber wins Kawasaki competition ready for BIM day New research has found that fewer than one in six firms in the building services sector are ‘fully ready’ to use Building Information Modelling (BIM), despite the government deadline for mandatory use of BIM level 2 for all centrally procured projects being less than six months away. Chris Meir, Sales Director at Andrews Water Heaters, says small to medium sized firms need to ensure they are equipped to deal with the changes. “Without properly engaging with BIM, and understanding specific requirements, there is a risk that SMEs could be tempted to buy into software solutions which may not be necessary,” he says. “There remain concerns as to how smaller contractors will fulfil the level of training and investment required to meet BIM requirements. When it comes to BIM, collaboration is king, but with the adoption

of new ways of working comes a serious time commitment, which is likely to weigh more heavily on businesses with less internal resource.

It is really flexible and goes exactly where you want it to.” JG Speedfit is a sponsor of Kawasaki British Superbike Racing Sponsorship and chose the prize of a Kawasaki ZX10R to highlight the connection.

GEBERIT Awards

Recognising quality, excellence and innovation in the plumbing and bathroom industries, the hunt is on for the best installers and apprentices in the land with this year’s Geberit Awards.

ominations are still open for the Geberit 2015 Awards, with prizes being given in the following four categories: • Best Domestic Bathroom Installer • Best Apprentice • Best Commercial Installer Team • Best Domestic Piping Installer Whether you take huge pride in your work and always go that extra mile to deliver a quality job, or work with an installer who is simply the cream of the crop, the nomination process takes just a few minutes to complete, and results in a huge amount of prestige for the winners. Each category winner will also receive £1000 in prize money. To be worthy winners, nominations need to illustrate how their Geberit product installations stand out from the crowd, how installers have overcome tricky challenges and just how far fitters have gone to ensure clients are left more

than a little satisfied with the end result. The Geberit 2015 Awards also recognise fledgling installer talent with the Best Apprentice award, whether you have a valued apprentice as part of your team or you are one yourself and pride yourself on being a quick learner who uses your own initiative and works with the latest technology.

How to enter To enter the Geberit Awards 2015, simply log on to www.geberit.co.uk/ awards and then explain in a maximum of 150 words, including details of a recent installation, why your nomination deserves to win. But don’t delay! The closing date for applications is 20th November.

How to be an award winner Last year’s winner of the UK Domestic Installer category, Jonathan Terry, provides an insight into what it takes to be a winner: “My main volume of work comes from luxury bathroom and wetroom projects. We use a lot of concealed cisterns and Geberit Duofix frames, as well as shower channels and shower wall drains. “I take a lot of care to ensure my customers understand the renovation process and are happy with what this entails and, of course, the overall results. I really want clients to have a positive experience by choosing my company

to install their bathroom. “All of my team have extremely high standards of work and are really respectful towards the clients and their living spaces. We get a lot of positive feedback about the quality of our finished

bathrooms and how we conduct ourselves during the project. “I only specify Geberit products – they are very high quality, extremely reliable and also easy to service, should any parts need renewing. “Since winning last year, business has been very good, and we have expanded to deal with an ever increasing work volume. I’ve used the publicity from the award to promote my company, and also updated my website to show my success. I would like to think that all this has helped me attract new clients.”

Training Update

Taking the right course Response to report How good training gives you know-how Whatever the advantages of new technology, it’s not always easy to adapt to new working methods – that’s why training has always been a key part of Geberit’s service to installers. Changing your methods of working, even when the benefits of doing so are pretty clear from everything you read and even hear from colleagues, can be a daunting prospect. In fact, this is one of the key reasons why, despite having been around for decades, press fit piping systems and wall-hung sanitaryware is still perceived as new technology by many. Thankfully installers are now recognising the benefits of change. And the reason for much of this reluctance? A misplaced lack of confidence in just how the latest installation systems work. However, all it takes is a few hours training and the opportunity to get hands on with the product, and then what we find is installers who wish they’d made the switch a long time ago.

Time out Training is an essential part of the job for anyone working in the plumbing and heating industry. But while ensuring you’re up to date with your Gas Safety certificate and other essential requirements is one thing, taking time out to undertake regular product training often gets overlooked, but that means taking advantage of the latest products and systems that can really help you up your game go overlooked too. Even if you’re the type of installer who feels that they can hit the ground running when new systems do become available, being able to get the most out of them really does come down to a short spell of training. After all, you wouldn’t drive a new car on the road if you hadn’t taken it for a test drive first, so the same should be true of using new products on site, particularly when it comes to installing heating and plumbing systems where ensuring safety is essential.

In the know Every product is different, as is every site, and Geberit Mapress is a good example of where training is essential. The system is really easy to install – in fact almost anyone could do it – but only with the right training. If corners are cut when using Geberit Mapress, such as getting the insertion depth wrong or not inserting the

on apprenticeships Apprenticeship training provider JTL has responded to a recent OFSTED report that appears to suggest that apprenticeships are delivering poor quality for money and resulting in many young people ‘under achieving’. Chief Executive of JTL Jon Graham argues that the report ignores the very positive results and outcomes that many specialist providers are delivering for the UK economy. He says: “We welcome the investigation into apprenticeship issues and their concerns around

quality, but we’d have liked to have seen more media coverage of the benefits of apprenticeships to the economy too – for instance a recent report estimated a Higher Apprenticeship can increase an individual’s lifetime earning potential by up to £150,000, comparable to the return for a university graduate. “Achievement rates on apprenticeships are higher than ever before, and we’re particularly delighted that through pre-screening and ongoing candidate assessment

JTL Chief Exec Jon Graham

and review, JTL consistently performs 10% higher than the national success rate in our apprenticeship training, with completion rates of around 80%.” JTL currently supports around 6000 apprentices across England and Wales.

pipe properly, leaks can occur. However, if these simple steps are adhered to, it’s one of the quickest and safest systems on the market. Deciding to forego such training for you and staff you may employ can prove costly. At Geberit, we recognise that training is an important part of using our products with confidence, which is why we have two dedicated and purpose-built training academies – one in Warwick and one in Dublin. All our training is also offered free of charge, as we know that installers are going to enough expense in taking time away from their day jobs in order to attend. Training modules cover all the basics of using Geberit systems, with installers having plenty of opportunity to try them out for themselves, so they can hit the ground running as soon as they use it on the job.

Bespoke packages However, it’s also important to remember that different installers will have different training needs. Some will already be familiar with press fitting, while others will be completely new to the idea. Some will be one-man bands while others will be looking to get an entire team of installers clued up on using the system so they are all working to the same level. That’s why we offer bespoke training packages too, and can carry out the training on site or at your place of work – whatever it takes to pass on the advantages of this press fitting system so that more installers have the confidence to make the switch.

The H008 training course for pellet stove installation is the latest to be added by HETAS for its registered members. “We are delighted to offer the new dry pellet stove installer course to our members,” says Mike Harvey, Training Manager. “Conscious of the ‘green’ agenda, an increasing number of homeowners are opting for this more efficient and sustainable way of heating their homes and we want to make sure our installers have brushed up

on their skills and are aware of the latest technologies in the industry.” The one day practical course will cover the d i f fer enc e s b et w e en appliances, together with installation issues such as chimney requirements, commissioning, customer preference, service and maintenance. Installers must have already completed the H003 dry installer competency course before embarking on the new H008 course. HETAS is the official

body for approving solid fuel and biomass heating appliances, fuels and services, and also provides training for all those involved in the industry chain. From installers and chimney sweeps to building control officers and local authorities, courses have been tailor-made to help heating professionals reach certified levels of nationally identified competency.

You’re never too old to learn Proving that you’re never too old to learn, 71-year-old John Washington has enrolled on a number of courses at Sussex based Steve Willis Training Centres over the years, having made the decision to gain some qualifications in plumbing some 25 years ago. John worked as an electrician for more than 10 years before deciding to move into plumbing. Initially self-taught, he then decided to get some qualifications and went on to become CORGI registered in the 1990s. It was then that he met with trainer Steve Willis and began the first of several courses taken with the training provider. “I really enjoy my job,” says John, who dismisses any idea of retirement. “I love seeing my customers, many I’ve worked with for years. It’s also good to know that by servicing their gas fires and boilers I’m doing my bit to ensure that people

are safe in their homes. “As for the training side of things – I was a little worried about whether I would be too old to renew my Fires (HTR1), Cookers (CKR1), Boilers and Water Heaters (CENWAT) qualifications, but Steve convinced me everything would be fine. “Although the guys were younger than me, the course

was a breeze. It was a good refresher that was enjoyable and covered everything we needed to know. Everyone was friendly too which really helped.” For further information about gas, plumbing or electrical short courses from Steve Willis Training Centres, please visit the website: www.stevewillis.com

Seven apprentices recently received certificates and prizes for being the first cohort of JTL apprentices to have completed their BPEC Level 3 Plumbing Qualification at Hull College.  The apprentices receiving their certificates on the day were Tom Dungworth, Jamie Milner, Luke Metcalfe, Liam Smith and Alex Berry (pictured l-r) – all from the Hull area. The two other apprentices who were unable to be at the event, but will receive their certificates at a later date, were Joe Norton and Bradley Cowley.

The event was held as part of the working partnership between BPEC and JTL. The CEOs of both organisations – Jon Graham from JTL and

Paul Johnson from BPEC – presented framed certificates and a set of tools to each of the successful apprentices. “We believe it’s important

to recognise excellence and these young men have worked hard for their qualification and deserve recognition,” says Paul Johnson. “We’re pleased that the ongoing partnership between BPEC and JTL continues to bear fruit and to deliver high quality young people into the plumbing industry.” To find out more about apprenticeships in the plumbing, heating and ventilating sectors, visit the JTL website at www. jtltraining.co.uk or the BPEC website at www.bpec.org.uk

Know more about underfloor heating Underfloor heating manufacturer Warmup offers RIBA and CIBSE accredited CPD training in underfloor heating. The ‘Introduction to Underfloor Heating’ module is pitched at a general knowledge level and covers: when to specify either hydronic or electric

underfloor heating; which type of system will best meet individual requirements; and the importance of research, zoning and controls. RIBA and CIBSE core curriculum areas comprise designing and construction; technology; and engineering.

The idea behind Warmup’s CPD is to ensure installers are qualified to specify the correct type of system, while understanding the installation process. The course will also address how introducing underfloor heating to buildings can make a significant, energy

efficient, and cost-effective impact towards meeting the current sustainability targets in the UK. To find out more about this introductory course, visit the website (www. warmup.co.uk/cpd-seminar) or email the company at: cpd@warmup.com.

32 COMPANY Spotlight

Good service is the key to success With a new 24/7 customer call centre and the launch of a 12 year warranty, Ariston UK believes it can offer installers a level of service that other companies will find hard to beat. PHAM News recently spoke to MD Mustafa Findik about the company’s plans for 2016 and beyond.

ith the likes of Amazon promising same day delivery and major supermarkets dropping the weekly shop to our front doors, there’s no doubt that the consumer’s view of what constitutes good service continues to rise. Can the heating industry match such levels of service? There’s one boiler manufacturer that believes it can. Last month saw Ariston launch a new 24/7 service MD Mustafa Findik offering, meaning that customers can contact the company any hour of the day, seven days a week – including Christmas day. It means that there will always be a point of contact available to deal with an enquiry, whether it’s about arranging a service or scheduling a visit from an engineer. “Customers today, whether they be installers or end users, have high expectations when it comes to service and I think it’s up to us as manufacturers to address that,” says Ariston UK’s Managing Director, Mustafa Findik. “We’re looking to set quite a high bar. That’s why we are the first mainstream boiler manufacturer to offer a 24/7 service. “We’re also looking to develop even higher service levels in terms of getting to calls quickly. I don’t think its unreasonable to try and respond to calls the same day or next day. We have to remember that if you don’t have heating or hot water, that’s quite a big deal. There are other industries that are perhaps not as essential to day-to-day living where companies appear to be able to deliver a better level of service. So I don’t see why we shouldn’t offer it in the heating industry.” As well as being contactable around-the-clock, Ariston has also invested in an upgrade to its service software system so that the company is now able to track and trace all service calls. It will enable the company to not only measure the level of calls it receives but also monitor the

The aim is to provide customers with a first-fix service

quality of its response. The goal is to be able to deliver a first-time fix by ensuring that all service engineers arrive knowing what boiler they’re about to look at and also with the right spare parts in the van. Key to attaining that objective is maintaining a close relationship with the independent installation companies that Ariston relies on to service its boilers. “We partner with engineers, so the people who service our products in the field probably install our products as well,” explains Mustafa. “Whereas other manufacturers may be looking to promote their own service operation, there is no clash of interest with our installer customers and we don’t see service as an opportunity to generate revenue. Everything we do is aimed at supporting more boiler installations. It’s about developing that partnership with installers, and we’re always looking at ways to improve that relationship.”

offering efficiencies of up to 90% and outputs ranging from 12 to 38kW. The company’s faith in its boiler range has recently been reaffirmed with the introduction of extended eight and 12 year warranties on its CLAS HE boilers. “We try to be ahead of the market,” Mustafa explains, “and the move to 12 years is in recognition of the increasing demand from our customers for extended warranties. The warranty will be one of the longest out there and I think it shows the confidence that we have in our products. We firmly believe in the high quality and longevity of our products. Customers purchasing one of these boilers can be reassured that not only are the products highly efficient, they are also built to last.”

Into training Investment in training is one of the ways that Ariston has looked to strengthen its relationship with installers in recent years. The manufacturer has opened 14 Centres of Excellence across the UK, each providing an opportunity for visitors to gain some practical, handson experience of its latest high efficiency boilers. “This year we launched the Ariston Academy programme, which is part of a long-term scheme where we’re really looking to differentiate ourselves in terms of being knowledge providers, with different courses and the promotion of best practice,” says Mustafa. “It’s been quite successful so far, but we’re only really at phase one in terms of what’s to come. We’ve effectively tripled our capacity for training and the challenge is now to get more installers enrolled on courses.” As well as avoiding potential installation issues, one of the objectives of Ariston’s push to increase the number of people it trains is to provide an opportunity for more installers to get first-hand experience of its product range. The company is confident that installers will be encouraged by what they see. “Many of those who haven’t used our product probably still view us as an ‘entry level’ boiler manufacturer, but our latest appliances represent market leading technology,” says Mustafa. “That’s why training is so important to us. We’re convinced that if we get installers in front of our boiler, and we train them, they will see for themselves the quality and high specification of the product.” The Ariston boiler range includes the CLAS HE evo, which features a stainless steel heat exchanger and boasts user-friendly interfaces, easy electrical connections and advanced control options. The boilers are claimed to have best-in-class low NOx emissions,

Broad range Of course the Ariston range extends to more than gasfired boilers, with an extensive range of cylinders and renewable heating options also part of its portfolio. Recent years have seen the introduction of the Nuos air source heat pump cylinder and a growing range of electric water heaters. “We are quite a balanced business, in terms of the boilers and water heating sides to the company,” says Mustafa. “The market continues to evolve and how it will change in the long-term is open to debate, but we’re growing across the whole business – both heating and water heating, and we are also gaining market share in renewables.” Further grounds for Mustafa’s positive outlook comes from the company’s move to new, more modern offices in High Wycombe in April last year and the recruitment of new people across the business. The emphasis has been on diversity, with more women on the management team, sales staff from a range of backgrounds and a new policy that will see the taking on of a least three graduates every year. Mustafa has now been at the company for six years, and as we approach the turn of the year he is confident that the company is in good shape to meet the challenges ahead. “I think we’ve been quite low profile in recent years,” he concedes, “but we want people to know that we’ve been quietly investing and there’s been a lot of change. We’re putting real emphasis on quality, training and customer service. It’s all about providing peace of mind for both installers and end users. “The statement of intent is our extended warranties. We wouldn’t be giving extended warranties if we had any doubts about the quality of our product. Installers also need to know that if there are any issues with our product, or our level of service, they will be dealt with. We don’t want to be just another ‘me too’ boiler manufacturer. It’s about setting ourselves apart.” www.ariston.com/uk

36 Health & Safety Time to exchange Concerns about test centre rigging those old ladders

Easy drugs check A new device for checking drugs use on site has been launched by Dräger. DrugCheck 3000 has been designed to test for impairment, as opposed to historical drug use, for up to five banned substances, making sure that workers are fit and safe to work in safety critical environments. The disposable kit can trace even minute traces of cannabis and will show if anyone has drugs in their system within minutes. “It’s worth remembering that employees who are impaired through the influence of drugs not only put their own health at risk, but also increase the risk of accidents involving others and machinery, with far-reaching consequences for the company,” says Marketing Manager Andrew Lowden. Designed for ‘on the go’ testing, the DrugCheck 3000 consists of two easy-to-use components – a swab for obtaining a salvia sample and a test cassette for the analysis. As well as cannabis, it can test for cocaine, opiates, amphetamines and methamphetamine. For more information, please visit www.drager.com

A recent BBC investigation has revealed that a number of test centres around the country have been rigging health and safety exams and awarding Construction Skills Certification Scheme cards to candidates who do not have a sufficient understanding of English to obtain the necessary qualifications. The joint investigation by BBC London and Newsnight discovered that some test centres are offering guaranteed passes for cash, resulting in untrained workers being allowed on construction sites. It is estimated that nearly 15% of construction workers come from abroad, approximately 228,000 people. The CITB (Construction Industry Training Board) has confirmed that it is aware of the problem of CSCS card fraud and has

taken a series of measures to tackle the issue. The Board has doubled its spend on fraud investigations, which has led to five centres being shut down and a further eight now under investigation. The building research organisation BSRIA has expressed concern about the revelations. Chief Executive Julia Evans comments: “Construction is the UK’s most dangerous employment sector and in the past five years alone, 221 workers have died. As an industry, we’ve set our stall on the CSCS card being the minimum benchmark to accept workers on to our sites. This scheme has to be trusted. BSRIA’s members demand best practice for the industry where its workforce must be safe. This exposure is clearly unacceptable.”

Tradespeople across all industries are being urged to take advantage of a scheme that offers substantial discounts on new ladders that are part exchanged for old, damaged and unsafe ladders. The Ladder Exchange Scheme is run by The Ladder Association and is open to all businesses and workplaces until the end of this year. Ladder and access equipment supplier Slingsby is one of a number of companies backing the scheme. Group Sales and Marketing Director Lee Wright comments: “It’s estimated that there are around two million ladders in use every day in the UK and falls from height remain a major cause of workplace accidents and fatalities. There’s no excuse for using a damaged or unsafe ladder and this scheme makes a huge difference in ridding workplaces of them by offering discounts on new ladders when they are exchanged for old and defective ones.” This year’s Ladder Exchange Scheme will again feature ‘Idiots on Ladders’ which is the Ladder Association’s popular competition that invites people to submit pictures shaming people who use ladders recklessly or dangerously.

38 STEP by step

Commission an XSeries burner Commissioning is an important part of any installation process to ensure it has been installed to industry standards. Peter Dempsey, Technical and Service Support Engineer at EOGB Energy Products Ltd, provides guidance on commissioning the domestic XSeries burner.

ere at EOGB we receive lots of enquiries into the commissioning of our XSeries domestic oil burners, and the one question we get asked the most is: “Is my burner already set up to suit my boiler?” Unfortunately, the answer is no. As every boiler has different recommended settings, this means that when a new XSeries is installed it will require a particular nozzle to be fitted and pump pressure to be set (this information can be found in the boiler manufacturer’s instructions). It is also vital to check and ensure what fuel the customer is using, as different fuels will also have different nozzle size recommendations and pump pressure. For example, if the burner is firing kerosene, the nozzle must be sized for a maximum pump pressure of 10 bar (145 psi). If gas oil is being used, then a smaller nozzle must be selected to allow a pump pressure of approximately 14 bar (200 psi). This is necessary to give better fuel atomisation and, in turn, better combustion. The XSeries is supplied with a test nozzle that we use to test fire each burner before it leaves our production line. However, this will normally have to be changed to the correct one as stated by the boiler manufacturer. Therefore it is essential that the burner is commissioned by a suitably qualified and competent oil engineer. To commission the XSeries burner, follow these key steps:

The average boiler has a recommended CO2 percentage in the range of 10.5% to 12.5%. For our boiler we are aiming to achieve 11.5% CO2 with CO (carbon monoxide) less than 100ppm.

(3) With a pump pressure now being registered, set the

pressure according to the boiler manufacturer’s instructions. If in doubt, contact either the boiler manufacturer or EOGB for further information. To alter the pump pressure, simply adjust the pressure adjuster on the pump. Clockwise rotation will increase pressure and anti-clockwise rotation will decrease pressure.

(6) If the CO2 reading is lower than what is recommended, you must decrease the O2 (oxygen). Turning the XSeries adjuster anti-clockwise will reduce the amount of air passing through the burner, reducing the amount of O2. This will cause our CO2 percentage to increase. If your CO2 is higher than what is recommended, then you will need to increase the O2. Turning the XSeries adjuster clockwise will increase the amount of air passing through the burner, increasing the amount of O2. This will cause our CO2 percentage to decrease. Keep making adjustments until the desired combustion figure is achieved. (7) Once the recommended

(4) With the manufacturer’s recommended nozzle fitted (1) Once the XSeries burner has been installed (see our EOGB YouTube channel for an instructional video on this process), bleed the air out of the pump and set the pump pressure in accordance with the boiler manufacturer’s instructions. To do this, first unscrew the pressure gauge port plug, screw in our pressure gauge, and then fasten securely with a spanner. (2) With the pressure gauge now fitted, turn on the oil supply and power. The burner motor should run and will start pressurising the oil. Any air that may be trapped in the pump and flexible oil line will need to be bled out. To bleed the air, simply open up the bleed valve on the pressure gauge manifold and run the burner until oil flows out. Once the oil is free-flowing, the pump has been bled of air and you can now close the bleed port valve. This will then allow the pressure gauge to register a reading.

and pump pressure set, the next step is to check and adjust the combustion figures. Before you insert a combustion analyser, we highly advise carrying out a smoke test to ensure that the combustion is clean so that you do not damage and block the combustion analyser. Black smoke generally means it is under-aired, so more air is required. White smoke means it is over-aired, so you need to keep adjusting the air setting up or down until the smoke clears. A smoke reading between 0-1 using a smoke scale is what you are looking to achieve.

combustions settings have been achieved, you need to record or print a copy for the commissioning report. These figures should only be printed and recorded once the boiler is up to temperature. Additionally, a second smoke test should be carried out, as combustion settings will have altered from the first test.

(8) The commissioning of the XSeries burner is now complete. Further commissioning of the site should then be carried out as per BS5410 part 1 and/or 2 to ensure all associated components and equipment is checked. Find out more (5) Once the smoke reading is between 0-1, you can alter the combustion figures to achieve the figures recommended by the boiler manufacturer. To achieve this, place the combustion analyser probe into the flue.

Circulating Pumps & System Treatment 41

Treat the cause, not the symptom Water quality is the key factor for optimum performance and system longevity in both domestic and light commercial heating installations. Martin Wilkinson, Spirotech UK’s National Sales Manager Commercial, looks at the benefits of a ‘fluid first’ approach.

he design stage is key for a light commercial heating system, regardless of the installation, whether it’s an office block, school or retail facility. Specifiers are now more selective about the suppliers and products that they use, prompted, in part, by the quality and efficiency of modern boilers and their component parts. Modern systems are the polar opposite of the cast iron, highly inefficient products traditionally Martin Wilkinson, National installed in light commercial Sales Manager Commercial environments. Today’s boilers for Spirotech UK are more efficient, cheaper to run and better performing. The downside is that such systems are highly sensitive and more susceptible to contamination and corrosion, brought about in most cases by poor water quality. Cast iron boilers could withstand dirt, but their modern counterparts cannot – they will slow, malfunction or fail completely if dirt (magnetite) is allowed to populate a system. Magnetic dirt will only collect where air is present, so this must be constantly removed from a system by deaeration or degassing. If it isn’t removed, dirt will collect and breakdowns will be the result.

System imbalance With the current emphasis on boiler quality and performance – geared around meeting stricter energy efficiency standards – water quality as an issue in itself is potentially at risk of being given scant consideration, which is to the detriment of long-term system health and functionality. Poor system water quality will inevitably lead to system imbalance, which spells bad news for maintenance and management teams. Imbalance can lead to a risk of decreased pump performance, the possibility of increased breakdown periods, excessive wear on component parts and higher energy consumption as a result. A poorly functioning system will result in a more expensive maintenance programme for management teams, and there is also the likelihood that system components will have to be replaced more frequently and the required energy

efficiency standards will be harder to meet as a result. Boilers and component parts on new systems will be ‘A’ or ‘B’ energy rated from day one of installation, yet the level of energy efficiency achieved may rapidly decline if the water isn’t treated correctly. For new installations, if the design is right for the building, and if the appropriate degassing unit has been specified for the size and type of building, then there’s an argument that no dirt separators should be required at all. Also, for that matter, there’s arguably no requirement to continually dose the system with inhibitors beyond the levels that are legally required, as heavy dosing can be more problematic in the long term. Indeed, Spirotech installations at commercial sites such as the University of Strathclyde, the Motorpoint Arena Cardiff and the University of Wolverhampton have shown that the need for chemical dosing can be significantly reduced.

like aluminium – when used for heat exchangers as part of a system – can actually speed up the corrosive process. Maintaining good water quality should be an ongoing consideration, and this is especially true when carrying out annual servicing and maintenance. The introduction of any new liquid into the system must be properly treated and degassed, otherwise oxygen-rich liquids will give rise to the problems associated with air. To ensure an air free system and a contaminant free circulating fluid, all water treatment programmes must include physical deaeration and dirt removal devices along with an appropriate dosing regime. A good initial design, delivered in conjunction with a respected partner, will help guard against many additional factors that can also allow air to enter the system, such as an expansion vessel being too small or located at the wrong point, an incorrect initial fill pressure or pressure differences over regulating valves. A key part of any good design, though, must recognise the importance of water quality as being at the root of a properly functioning system. If water quality is maintained, air and dirt will not populate and the resulting problems will not arise – resulting in a healthier and better performing heating system.

Chemical concerns This issue is an important one to be aware of. While chemicals do have an important role to play when used correctly, overdosing of systems can have an adverse effect, especially when we consider that certain materials,

New commercial chemicals to optimise performance An enhanced range of commercial chemical water treatment products has been launched by Fernox, including: FC1 Inhibitor, FC3 Cleaner and FC1 Filter Fluid+ Inhibitor. Specifically designed for larger commercial systems, the three new products provide contractors with the high quality and reliable solutions needed to maintain energy efficient heating systems and protect vital system components from breakdown and failure.

41.indd 1

The FC3 Cleaner has been designed to purge commercial systems from harmful sludge and debris and restore the efficiency of existing systems. It is also said to be ideal as a pre-commission cleaner for new installations and suitable for use when flushing. Once the system water is clean, the FC1 Inhibitor can be used to protect against limescale build-up and corrosion formation.

The proven formulation is designed to be left within the system to maintain system efficiency and extend component longevity. In cases where conventional flushing is difficult, not practical, or even where

high pressure powerflushing could create further system problems, then Fernox recommends the new FC1 Filter Fluid+ Inhibitor. The product combines the proven effectiveness of F1 inhibitor with an active dispersant

package to detect, lift and deliver contaminants to a system filter.

What to look for in a filter The magnetic filter market has grown rapidly in recent years, but with such a wide choice available how can you be sure you’ve chosen wisely? We asked Eclipse Magnetics, manufacturer of Boilermag, for advice.

ost installers are pretty clued-up over what a system filter does and why it is important to consider installing one, but how can you be sure that you have chosen the best filter for the job? If the filter is not performing, the same problems, such as radiator cold spots, breakdowns, noise in the boiler, etc, will simply reoccur. Heating efficiency will start to deteriorate, so it’s important to ask a few salient questions before making a decision which filter to run with. Here are some of the questions that may help you to avoid the potential for future problems: • Does the filter capture magnetic materials such as black magnetite sludge and also non-magnetic materials – scale, excess flux and copper filings? • How effective is the filter on the first pass of system water through the filter? • How big is the magnet in the filter? Size definitely matters, whatever you may have been told! • How does the system water flow around the filter? Does it give the debris the maximum opportunity to be filtered from the circulating water?

shown that some filters remove as little as 20% due to design limitations. Let’s look at the magnet. Make sure the magnet is of neodymium material. The sheer size of the magnet is very important. Having a bigger magnet increases the exposure of the water to the magnet, resulting in a greater debris collection performance. Despite pressure to reduce costs, this is one area on which the design engineers at Boilermag have refused to compromise. Our magnetic core is a whopping 60.8cm³ – nearly twice as big as the nearest competitor. • What is the volume of the collection capacity for the debris? Too small and the debris will flow on through and circulate in the system again.

Passing the test First pass efficiency is a key judging criteria – the more debris that’s removed on first pass, the less remains to flow through the boiler heat exchanger and it’s less likely to become attached to valves, radiators or pumps. Whilst no filter can remove 100% of contamination, it is important to remove at least 90% on the first pass. Research has

Making the right choice

Go with the flow In addition to size, strength and location of the magnet, it’s important how the water flows around the magnet. Some filters speed up the flow of water when it passes through, thereby minimising the time spent in the filter chamber, resulting sadly in reduced performance. At Boilermag we have a patented ‘dual flow’ arrangement which slows down the flow and particle velocity, allowing it more time to be collected by the magnet. In addition, the dual chamber arrangement means that water is exposed to the magnet twice on each pass. Finally, the collection capacity. A factor which influences the performance of all filters is the collection capacity. If the collection area becomes full, contamination will continue to circulate. Collection capacity is different to the internal volume of the filter. Some filters may have an internal volume of 500ml or more, but due to inefficient magnets or flow paths they can only collect less than 200 grams of contamination before the filter needs cleaning.

How water flows around the magnet will make a difference to the effectiveness of the filter

If you consider that filters are normally cleaned only during the annual servicing, there will be instances where the filter becomes saturated with contamination and no longer works. It all depends on the condition of the system but ideally it is best to use a filter with a 400 grams or more collection capacity. In most average sized 100 litre heating systems this would give sufficient collection capacity between annual servicing. PHAM NEWS ENQUIRY No.

Aberdeen City Council and its current gas maintenance contractor, Gas Call Services, is one of the latest partnerships to recognise the benefits of installing the Boilermag. Gas Call Services has over 130 engineers on the road, providing year-round coverage to a variety of domestic and commercial properties. Its primary role is working for social housing landlords and it currently provides its services to over 50,000 residents. The company’s call centre handles more than 250,000 calls every year and its engineers attend more than 100,000 service visits. “We take what we do very seriously and like to test equipment to see that it’s delivering the best possible performance for our customers,” says Operations Manager Stuart Laming. “System filters have become an essential part of heating system design, so we decided to review and test all the leading brands in the marketplace for performance and practicality – including the ease of fit. So we compared different models and specifications to propose to our clients and asked our installers for their input. They in particular liked the Boilermag features such as the 360 degree adjustment, and in-line fit capability.

“We also liked the fact that Boilermag has a large collection capacity which is key and allows the unit to continue to work effectively between annual service visits. It is also more compact in height than some of the other units. All round, Boilermag came out top of the tests we undertook and following approval from Aberdeen City Council, we made the decision to switch to Boilermag. “Since we began installing the Boilermag filters on the service and maintenance contract, the council has seen a dramatic drop in call outs from the properties where they have been fitted.”

Maintaining a top grade system High rated boilers offer lower energy consumption when first installed, but without proper water treatment, efficiency levels are sure to quickly diminish. Daniel Cheung, UK Trade Marketing Manager at Sentinel, encourages installers to follow a three-step programme.

ith the Energy related Products (ErP) Directive now in force, homeowners can enjoy the reassurance that comes with having boilers, certain components, and heating systems labelled according a new, extended energy rating banding scale. Indeed, the benefits associated with higher rated systems include reduced energy bills, lower carbon emissions, and a Daniel Cheung, Sentinel’s UK warm home. The question, Trade Marketing Manager however, is for how long? Unfortunately, without an ongoing programme of high quality water treatment, such advantages soon ebb away. For instance, the corrosion of system metals can lead to radiator cold spots and inefficient operation of vital boiler components such as the heat exchanger and pump. In fact, corrosion deposits can typically cause a 15% reduction in the effectiveness of the radiators and the system as a whole. Moreover, it won’t take long for this to lead to an expensive repair or even replacement situation. Furthermore, independent research by Gastec@CRE has found that fouling caused by sludge build-up can reduce the efficiency of a domestic boiler by at least 3%. Although this may not sound much, it could be sufficient to drop the operating efficiency of a boiler down by an entire energy rating band – for example an ‘A’ rated boiler could have a true operating efficiency of a ‘B’ rated boiler, a ‘B’ rated boiler the operating efficiency of a ‘C’ rated boiler, and so on.

Useful sales tool By proactively promoting the benefits of best practice water treatment to customers, South West London-based plumbing firm WPJ Services Ltd reports that it has seen a significant increase in the take-up of its water treatment services. The company has been using Sentinel’s ‘Homeowner’s Guide to Water Treatment’ leaflets to initiate and guide conversations with homeowners about the benefits of water treatment and says that it has helped to convert around 70% of customers, with more than half going for a powerflush. “Previously, our installers found it difficult to talk to customers about water treatment – after all, they’re heating engineers, not salesmen!” says PJ Luard, Director at WPJ Services. “However, since we’ve started using the leaflet, discussing our services is easy. It does most of the job for us, and if we forget any handy facts, like the cost savings associated with cleaning a dirty system, they’re right there in front of us.” The leaflet is available via Sentinel’s CPM app or can be ordered from: www.sentinelprotects.com.

Good maintenance guide Boilers account for more than half of what homeowners spend on their heating bills, so it makes sense to keep the system in tip top order. Adey MD John Vaughan explains how installers can help customers save.

ust a decade ago, the average annual household energy bill was £472. Today it stands at a whopping £1265, so it’s not surprising that many households continue to look for ways to cut their energy usage. However, research by Adey reveals most are missing out on one of the simplest ways to save.

Boiler MOT A recent study revealed that only 46% of the 1300 UK homeowners surveyed had their boiler serviced in the past 12 months. One in 10 consider an annual boiler service an unnecessary expense. This means that every year, thousands of boilers are left chugging away without checks to ensure that they’re running efficiently or even safely. In fact, 20% of householders only took any notice of their hard working boiler when something went wrong. We believe that having an annual service should be considered just as important as a car’s MOT. While it’s

not a legal requirement, it will ensure that the boiler and heating system are running as they should, helping to keep potentially costly repairs at bay and any boiler warranties intact. More importantly, it could also help to keep a household safe from the dangers of carbon monoxide, particularly on ageing systems. Few homeowners will understand that the small parts and narrow waterways of today’s super-efficient condensing boilers are prone to the damaging effects of the natural corrosion that happens inside every heating system. However, treating the symptoms caused by debris in the system is an installer’s daily bread and butter.

Giving advice Those installers who can effectively communicate with their customers to help them understand the benefits of ongoing heating system maintenance and protection will reap the benefits. This is one of the

many reasons why we developed an award-winning approach to best practice. It enables installers to easily communicate the crucial ingredients for ultimate system protection in four simple steps.

Best practice Our recommended best practice follows the maintenance mantra of clean, flush, maintain, protect. The combined effect of system cleaning, quality water treatment chemicals and the most effective magnetic filtration work to improve system efficiency, protect against breakdown and reduce heating bills. Adopting best practice can also help installers to build a reputation for excellent customer service and encourage repeat business. Statistics from Moneywise show that typically, a fifth of UK households have a boiler breakdown over the winter, at an average repair cost of £320. However, a new study has

highlighted the worrying number of households unprepared to cover these unexpected emergency costs, with many admitting it would drive them into debt. Most UK householders (55%) said that if they were hit with a bill for emergency heating repairs of £1000 or more, they would have to ask for a bank loan to cover the cost. To pay a bill of £250, 49% said they’d have to borrow the money from friends or family and 30% said they’d need to pay by credit card.

Right step By encouraging customers to take steps to maintain and protect their heating systems effectively for the long term, installers can help them reduce this financial risk and ensure their boiler is ready to make it through this winter, and many more. Today, MagnaClean filters and MC+ chemicals are collectively protecting three million UK central heating systems, helping them

We estimate savings of up to 15% on individual annual household heating bills where our best practice approach to central heating system maintenance is employed, using proven, effective filters and high quality chemicals.

Water contains two different types of hardness ions, with the calcium ion the one that causes scale. The scale causing calcium ion (dissolved limescale) passes through a bed of food grade ceramic beads within the unit and is transformed into a non-scale causing calcium crystal. The crystals then attach themselves to the beads. When they reach a certain

size, they release themselves from the beads back into the water, where they adhere themselves to the post filter. As a result of this physical change, which Monarch says is permanent, scale no longer has the possibility of forming on surfaces including heating coils and elements, fittings, the inside of pipes, etc. PHAM NEWS ENQUIRY No.

Ground source is best choice Faced with the challenge of keeping £15m worth of steel at the perfect temperature and humidity levels – while maintaining low energy costs – major logistics firm AV Dawson has fitted ten NIBE ground source heat pumps (GSHPs) at its new warehouse in Teesside. The 130,000m3 warehouse has been built specifically to store steel coils for a nearby car manufacturer. With steel at risk of ‘sweating’ and rusting in high humidity levels exceeding 65%, AV Dawson was tasked with ensuring a very specific climate for the warehouse, without which the steel would be rendered unusable. NIBE GSHPs provided the optimum solution – guaranteeing consistently low humidity

levels, while keeping energy costs to a minimum. The ten F1345 60kW GSHPs are each paired with their own ventilating unit and 500L NIBE UKV buffer tank – producing a total output of 600kW. Solar panels on the roof provide

an additional 220kW to help meet the warehouse’s electricity needs. Howard Tribick, Director at HT Energy, specified, designed and fitted the heat pump system. He explains: “We considered a whole host of options, but none matched up to the NIBE GSHPs when it came to ensuring high efficiency and reliability, matched with minimal maintenance and long-term cost savings.” AV Dawson MD Gary Dawson adds: “This system made perfect commercial sense for us. While the initial outlay was greater than some of the other alternatives, GSHPs provided the most cost-effective solution by far in the long term.” PHAM NEWS ENQUIRY No.

MERCHANT & Distributor News 53 Enter the experts Martial arts ace behind the counter

New branch in York York is the site of Plumbase’s newest kitchen and bathroom showroom, located on Fawcett Street. The new showroom stretches over 3000ft 2, incorporating a revamped bathroom area with 20 displays as well as a new kitchen offering. Plumbase York is one of several new showrooms rolling out across the UK this year, combining Plumbase expertise with leading manufacturers. The concept is designed to encourage the trade to bring their customers

to the showroom so they can choose for themselves from the range of kitchens and bathrooms. Commenting on the new showroom, Andrew Arnold, Plumbase Divisional Showroom Manager for the North and Scotland, says: “It’s beautifully designed so that tradespeople can be confident in bringing their customers. Of course, consumers are also welcome on their own and can benefit from our trade expertise and installation knowledge.”

With the aim of bringing a superior level of knowledge to its network of branches, Graham Plumbers’ Merchant has assigned 33 Product Experts across its Plastics, Heating Spares and Smart Controls divisions. Following the completion of a dedicated training programme, the ‘Product Experts’ – based in central branch locations across the country – will be responsible for helping any branches that may need some extra help or assistance within their designated area of expertise. In order to become a Product Expert, staff not only completed a thorough training programme but also visited a series of suppliers in order to better understand the breadth of products available as well as get an insight into the manufacturing processes. Product Experts also received hands-on training in areas such as wiring smart controls in order to better assist customers and colleagues alike.

A Liverpool plumbing merchant is enjoying success off the job too as he recently earned the title of British Taekwondo champion. The 37-year-old Tony Wilkinson is also the manager of the James Hargreaves Plumbing Depot. Tony earned the title with a sterling performance in the national finals held in Manchester. “I got knocked out in the first round last year and vowed that it would never happen again,” he says. “I upped my game in terms of training intensity and paid extra attention to my diet. Thankfully, it all paid off.” Tony was the lightest in the heavyweight section and faced some tough opponents, but friends were on hand to cheer him to victory. “Martial arts are about discipline and enhancing physical and mental development, and these have definitely had a genuine knock-on effect in

54 Ventilation & Heat Recovery

No need to make a big noise about ventilation High fan noise levels have long been a bugbear for homeowners and tenants, but the latest ventilation solutions have proved that it is possible to both improve performance levels and reduce nuisance noise. Lee Stones, Category Manager at Xpelair, explains more.

peak to any bathroom installer and they will be familiar with the concept of inline shower fans. Designed to reduce condensation in the bathroom and prevent the build-up of mould, they have been a mainstay of the bathroom ventilation market for many years, combining high margin opportunities for installers with the simplest of operation for homeowners. But what if there is a better Lee Stones, Category Manager way of doing things? That is exactly what we’ve been asking at Xpelair as part of our continued programme of innovative product development. Inline fans are designed with the fan hidden within the loft space, positioned between two lengths of flexible ducting leading to the bathroom and the outside wall. Traditionally, this design has prevented the need for a noisy fan to be positioned on the ceiling directly above the shower, although many would argue that what’s gained in noise reduction is lost in airflow performance – not to mention the inconvenience of installation and maintenance in the dark, difficult loft space. Now, thanks to a fresh pair of eyes, we believe it’s time for a new way to approach shower fans.

Quietly does it One of the main advancements in domestic ventilation in recent years has been the reduction in the noise level of domestic fans. We recently invested in an independent study that showed that around 14.5 million UK adults are being affected by having a noisy bathroom fan in their home and more than 4.5 million adults have been woken up or kept awake by a noisy fan. More than an inconvenience, the findings prove that unnecessary discomfort, stress and even poor health can

Ghost Air Movement explained The Simply Silent Shower Fan Complete is the latest addition to Xpelair’s family of Simply Silent products, a collection of energy efficient indoor air quality and air comfort solutions designed to improve well-being and comfort. The new fan range has been made possible thanks to advancements made in reducing the noise of fans incorporating Ghost Air Movement Technology. Fan noise comes from both the motor and the movement of air. To combat this, Xpelair’s Ghost Air Movement Technology uses long-life silent running motors and precision engineered components to avoid mechanical noise whilst advanced air flow management eliminates irregular air flow paths and turbulence.

to be hidden in the loft space. Instead, ceiling mounted shower fans can deliver improved performance, simple installation and easier access to the product for maintenance. And combined with the timeless, stylish design of our latest DX range, it is an enticing package for installers and customers alike.

Time saver To save time on installation, our Simply Silent Shower Fan Complete consists of a ceiling mounted shower fan sold complete with self-contained duct and external grille. This packaged solution also saves time on maintenance compared to inline models. Our new Simply Silent Illumi Shower Fan Complete will also come as a one-box solution, complete with added integrated light. Many in the trade will have already have fitted a fan like this by purchasing the individual components – but this is the first shower fan packaged in this way and brought to market. The Simply Silent Contour Fan installed in a bathroom

be attributed to noisy bathroom fans. This is without taking into account the effect noisy fans can have on new parents, eager to make sure their babies and toddlers are getting an uninterrupted night’s sleep. The research highlights a very real problem for many homeowners but it also suggests people are just putting up with noisy fans – perhaps because they don’t know any better. Highlighting the issue, of course, is just one part of the problem. Now it is vital for manufacturers like Xpelair to provide bathroom installers and electricians with the products to help their customers – because high performance levels do not necessarily mean high noise levels. Our mission is to make all of our bathroom fans silent and really set the industry benchmark. We are committed to improving health and wellbeing through indoor air quality and air comfort – and this includes noise levels in the bathroom.

Growing range Our customer research has helped to drive the development of the Simply Silent family, a wide range of domestic solutions using our innovative Ghost Air Movement Technology to deliver near-silent running. With Simply Silent Contour, Contour Constant Volume, and DX100 wall or ceiling mounted fans – together with the introduction of the Simply Silent Illumi this December – the product line continues to grow. The Simply Silent family has tackled the issue of noise from the bathroom head-on and delivered a high performance solution to help installers meet demand from homeowners, housebuilders and social landlords – but it has also opened up new opportunities for shower fans. With near silent running, shower fans no longer have

Air quality As the issue of indoor air quality continues to gain exposure, so too does the importance of good ventilation to reduce the build-up of condensation, black mould and spores which can be unsightly in the home and potentially dangerous to our health. We spend more than 90% of our time indoors but many homeowners are still unaware that indoor air can, in fact, be as much as 50 times more polluted than outdoor air. Poor indoor air quality can aggravate pre-existing health conditions such as asthma and eczema as well as fatigue, rhinitis, dizziness, headaches, coughing and sneezing – so it’s crucial that adequate ventilation is fit for purpose. Any fan, whether it is silent or not, must effectively eliminate humidity, condensation and odour to improve air quality in bathrooms, shower rooms, cloakrooms and toilets. Our Simply Silent Shower Fan Complete offers installed airflow performance of 55m³/hr with 3m of ducting and one bend, versus inline competitor airflows of 29.5m³/hr with 3m of ducting and one bend.

Better business Of course, all of this can deliver a huge selling point for installers. Whether they know it or not, consumers can enjoy significant benefits from a growing number of high performance, near-silent bathroom fans – and it’s up to bathroom installers and electricians to highlight that fact. This added value proposition offers high margin opportunities within bigger bathroom projects, not to mention retrofit potential from customers who might not have otherwise considered changing their fan until they are informed about the benefits. Above all, it means greater profit making opportunities for tradesmen. www.xpelair.co.uk

What to consider

Full service lab produces results The Airflow Lab at Waterloo Air Products provides customers with the information they need to help ensure projects run smoothly. Part of the company’s Tech Hub, the lab’s capabilities include heated flooring, heated walls, adjustable ductwork in the ceiling and floor, with a floor void for floor grilles along with a wall partition that can be adjusted to the required room size, enabling mockups in the test lab. Recently, Atkins, a design, engineering and project management consultancy, sent a group of its apprentice engineers to Waterloo’s head office in Maidstone for training, which included a practical demonstration in the Airflow Lab.

“As Waterloo continues to grow and maintain its status as one of the leaders in air distribution, we ensure investment goes into the heart of our business and more specifically into our lab testing facilities,”

explains Rick Edmondson, Chairman of Waterloo. “Waterloo’s lab has a range of high-tech equipment that is very capable and reliable for the high demand of training and test requests we receive.”

Training is also a part of the services provided by Waterloo. Matreya Southgate, Product and Development Manager, comments: “When we run training days we want attendees to be engaged and carrying out a smoke test is a great way of injecting some fun in the training which we hope will be memorable. “Waterloo is one of the most knowledgeable companies in the industry when it comes to understanding air distribution. We aim to pass on our knowledge and inspire students attending our training days. Judging by the feedback we receive, our courses are very beneficial,” concludes Matreya. PHAM NEWS ENQUIRY No.

So what should we be looking for? For new homes, it could be about providing filtration on its systems at the entry level to a property – filtering the incoming air from the outside of the building. Particularly in urban areas, the levels of toxins – in particular nitrogen dioxide and particulates from heavy traffic – can cause havoc, so they need to be addressed. At Nuaire we offer both solutions for residential and commercial buildings that are part of a system design. For existing properties, it’s often about having a retrofit solution that does not require massive renovation to the walls and ceilings. In our homes the option of positive input ventilation (PIV) works well here. PIV sees air pushed into the building at a constant rate, forcing air circulation around the interior. A properly installed unit will ensure that old, contaminated and moisture-laden air in the property is continuously diluted, displaced and replaced with good quality, fresh air. The result is an environment in which condensation dampness cannot exist, and where allergens and pollutants are kept to a minimum. More importantly this solution is easy and quick to fit, so minimal disruption to get good indoor air quality.

VENTILATIon & Heat Recovery 57

The danger of airtight buildings Recent studies have highlighted the damaging effects of poor indoor air quality, reinforcing the need for houses to have a constant supply of air to keep occupants healthy. Paul Rainbird, Operations Manager at Titon, looks at how indoor air quality can be improved.

ccording to the BRE, the average European citizen spends at least 90% of their time indoors. Given this statistic, indoor air quality becomes very important – after all, it has a major influence on the health, comfort and wellbeing of a building’s occupants. Now, with modern properties designed to be as airtight as possible (in order to keep energy bills low and prevent warm air from escaping) there is a growing concern that ventilation levels are being put at risk. A lack of ventilation can result in stale, contaminated and humid air building up in homes – which can lead to serious illness for occupants. Recent reports and research have outlined ‘Toxic Home Syndrome’ as a condition affecting 15.3 million homes across the UK, which has seen people’s health deteriorate as the result of poor quality air circulating inside their properties.

Growing mould Airtightness in homes can lead to issues such as condensation and mould, which provides an environment in which pollutants can thrive. Mould is a notable concern, as it is a fungus that flourishes amidst water and warm temperatures. Some types can release allergens, irritants and toxic substances that have been linked to immune system disorders, such as asthma and allergies. Plus, according to a YouGov consumer survey conducted on behalf of BEAMA, people with mould in their homes are 19% more likely to suffer from a respiratory or dermatological condition. The presence of moulds within the home is a reflection of poor ventilation and increased humidity. Homes with mould are also likely to have higher dust mite allergen levels and this may worsen both respiratory and skin conditions. A lack of adequate ventilation within a home can also be associated with the build-up of non-allergenic noxious fumes which are detrimental to health. Other pollutants released by household items can also affect indoor air quality. For instance, a lot of everyday cleaning products (including air fresheners, carpet cleaners, polish and oven cleaners) are made from chemicals containing Volatile Organic Compounds (VOCs), which can irritate the lungs. VOCs within the home are measured in levels of ‘moderate’, ‘elevated’ or ‘severe’. When these levels increase, aggravated health problems are more likely to occur, so it is important this issue is addressed. There is currently guidance on the total VOC

limit in Part F of the Building Regulations ‘Means of Ventilation’ Appendix A, which specifies a limit of over 300ng/L over eight hours (post-construction, but pre-occupancy). Similar guidance is given in BREEAM, which specifies a limit of 300ng/L over eight hours (post-construction, but pre-occupancy), in line with building regulation requirements. Of course, indoor air quality can be significantly improved (and the threats of pollutants greatly reduced) by effective ventilation. However, according to BEAMA, only 2% of UK homes have mechanical ventilation installed – which means those that don’t are at risk from elevated VOCs.

MVHR systems Mechanical ventilation with heat recovery (MVHR) systems are ideal for new build properties. MVHR systems have been specified into many new build houses and apartments due to the benefits they offer under SAP (the Standard Assessment Procedure) Appendix Q. MVHR systems remove moisture and pollutants from the air, ensuring a comfortable – and healthy – indoor environment. Alternatively, the addition of trickle vents to windows will assist in reducing indoor air pollutants substantially, at very little extra cost. Replacement windows will be better sealed than those being replaced – which only increases the need for improved ventilation. In fact, trickle vents are advisable in most replacement window situations, as they help prevent condensation arising and subsequently mould growth.

Living habits Sometimes, a simple change in living habits will go some way towards improving indoor air quality, such as not drying washing indoors and opening windows whenever possible. Identifying the ventilation system

MVHR systems will remove moisture and pollutants

already installed in a home and cleaning and maintaining it may be all that’s required. For example, if extract fans and trickle ventilators are already installed, the fans may simply need cleaning and the trickle vents opening. Ventilation systems will become more important in the continuing drive towards more energy efficient homes, as this

will only see properties becoming even more airtight via increased insulation and double glazed windows. Without ventilation, the occupants of these airtight buildings really will be at risk from the health problems associated with poor indoor air quality. PHAM NEWS ENQUIRY No.

58 Ventilation & Heat Recovery

Improving air quality and saving energy With pressure being placed on the managers of commercial buildings to improve energy efficiency and reduce carbon emissions, is indoor air quality (IAQ) taking a back seat, or can both equally important issues be achieved in harmony? Yan Evans, Vice President of Fläkt Woods UK, explains how specifying the right system can do both at the same time.

here is no question that the commercial sector has a significant role to play in meeting UK carbon reduction commitments, and heating and cooling in particular accounts for a considerable amount of a commercial building’s energy consumption. It is therefore unsurprising that for organisations in both the public and private sector, improving energy efficiency is likely to take priority when specifying an HVAC system, Yan Evans, Vice President of sometimes at the expense Fläkt Woods UK of indoor air quality (IAQ). However, it is crucial for heating engineers to understand the impact poor IAQ can have on building occupants, and ensure they can confidently advise customers seeking a new heating and ventilation system.

It is first essential to understand the impact poor IAQ can have, and ensure that any new system will adequately ventilate the property. Figures suggest that we spend more than 90% of our time indoors, but whilst there is a good understanding of outdoor air pollution, few people realise that indoor air can be as much as 50 times more polluted than outdoor air. As humans expel carbon dioxide, there can be a high concentration of this gas in densely occupied, confined areas such as offices. Regular exposure to CO2 can result in lethargy, sleepiness and reduced concentration – having an adverse effect on the productivity of employees. The NHS now even recognises how common symptoms can be attributed to poor IAQ in the form of ‘sick building syndrome’ and sign posts businesses to invest in better ventilation to help reduce symptoms. Worryingly, statistics indicate half the British workforce have suffered headaches, tiredness and felt less productive because of stale air and stuffy working environments – making the necessity for effective ventilation systems, and thus, improved IAQ, even more conclusive.

Providing a whole house solution Rebecca McLean from EnviroVent looks at how the latest MVHR systems are helping the new build sector to meet the latest regulatory requirements and how the ErP Directive is encouraging a move to a more systems-based approach to ventilation.

xperts have warned that the number of Britons with asthma could almost double to over 10m by 2050 because of poor air quality inside homes. Recent studies by Reading University focused on the build-up of pollutants in indoor air that may be released by building products, furnishings, consumer products such as hair sprays and furniture polish, as well as pets. Continued exposure to these pollutants could result in a variety of ailments, ranging from asthma and allergies to an increased risk of lung cancer and heart disease. One of the very worrying conclusions of the research carried out at Reading University is that by 2050, declining air quality could lead to an 80% increase in the 5.4m people who already suffer with asthma. Evidence shows that airborne pollutants are at higher levels in newly built and refurbished homes, rather than older properties. It is believed that this has been exacerbated by the trend towards greater air tightness, which in turn elevates humidity levels by keeping moisture-laden air trapped inside. Greater awareness of the issue of poor indoor air quality and the more stringent building regulations requirements for new homes means that the number of Mechanical Ventilation with Heat Recovery (MVHR) systems specified is set to increase significantly in the next few years. It was recognised some time ago that when homes are built to the higher energy efficiency levels, some form of mechanical

ventilation is required to prevent issues associated with poor indoor air quality. MVHR systems work by extracting warm, moisture laden air from the â&#x20AC;&#x2DC;wet zonesâ&#x20AC;&#x2122; of a home (kitchen, bathroom and ensuites) and passing it over a heat exchange cell to recover the heat before it is expelled to the outside. At the same time, cool fresh outside air is also drawn through the heat exchanger where it collects the recovered energy and is tempered before being released into the living areas of a property. Poor indoor air quality, often characterised by high humidity, can provide a breeding ground for

du s t mites, which can exacerbate asthmatic and other breathing related conditions, as well as skin complaints. Poorly ventilated homes can also become damp and prone to condensation which eventually leads to mould growth, causing damage to the fabric of the building and respiratory health issues.

ErP Directive Another reason for the widespread adoption of MVHR by the new build sector is the latest ErP Directive, which is encouraging a move to a more systems-based approach to

ventilation. It was first introduced in 2013 and the second stage of the legislation, which is due to be released in 2016, focuses on ventilation units over 30W. This mainly impacts on Mechanical Extract Ventilation and MVHR systems and requires all ventilation units, except dual use versions to be equipped with a multi-speed or variable speed drive. In addition, all bidirectional units are required to have a thermal by-pass facility as an essential part of the design criteria, which prevents warm air being recovered in warmer weather, keeping the property cooler during summer. MVHR is also helping the new build sector to cost-effectively contribute towards the improvements in CO2 emissions required by Building Regulations by lowering dwelling emission rates (DER). With MVHR, the incoming air is filtered, improving internal air quality and recovering the energy that would normally be lost through traditional ventilation methods. It also means there is no need for window trickle vents. The result is improved performance under the Governmentâ&#x20AC;&#x2122;s Standard Assessment Procedure for energy ratings in dwellings (SAP) as MVHR delivers the most favourable return when compared to other ventilation methods.

Better solution At EnviroVent we have responded to the increased requirements for ventilation by introducing MVHR systems that are ideal for new homes, preventing condensation, damp and associated health issues. Systems like our energiSava 300/400 (pictured below) offer high energy efficiency and feature a summer bypass facility, therefore making them fully compliant with the latest ErP Directive for ventilation units. Installers of ventilation systems could find there are increased opportunities to work within the new build sector to fit MVHR systems. The trend towards fitting MVHR systems into new homes looks set to continue, driven by ever tightening legislation and the increasing demands of homeowners for improved indoor air quality.

Taking the heat out of the kitchen With steam and grease in abundance, a well designed ventilation system will play a crucial role in any commercial kitchen. So how do you take the heat out of the kitchen? Steve Leonard, MD of Ledaire Fabrications, suggests some core ingredients of the ideal system.

atering can be a hugely rewarding occupation, but there are recognised health and safety concerns arising from working in what may be a hot, steamy, grease-laden environment. The risks divide into three areas, being those associated with personal health, those associated with general food hygiene and those concerned with third party safety. In all cases, a major part of the solution lies with the provision of efficient ventilation, expelling fumes while encouraging the ingress of fresh, clean air to provide a comfortable, safe working Steve Leonard, Managing Director at Ledaire Fabrications environment.

There are a many factors to take into consideration when planning the ventilation aspects of a kitchen. As well as the immediate requirement to evacuate fumes there is an ongoing need to avoid the build-up of grease in the ducting and prevent insect pests from being drawn in with replacement air. Most cooking oils flash off flammable vapours above 200°C, a flashpoint which reduces as a result of oxidation arising from repeated use. In addition, different styles of cooking produce different mixes of grease and vapour. Prevention of grease accumulation is therefore a particularly important issue. If not addressed it provides both a convenient feeding ground for bacteria and insects, and a powerful accelerant in the event of fire. There have been a number of instances of fires in catering establishments whose

control has been hindered by local accumulations of grease. HSE recommends a kitchen ventilation rate of not less than 17.5 litres/sec per square metre of floor area or 30 full volume air changes per hour. While this is acceptable in mid-summer, the substantial loss of environmental heat may be less welcome during the winter months when a more controllable ventilation regime will generally be desirable. A basic type extraction hood will simply discharge a given volume of fume-laden air to atmosphere, along with all of the heat it contains. However, induction hoods partially separate fume extraction from the ventilation function. They draw in externally sourced fresh air which is discharged into the hood at high velocity. This creates a low pressure zone above the work area; it helps to draw cooking fumes up into the
