All about you

FROM THE EDITOR

Comment T

his month marks a whole year that we’ve been living with the restrictions caused by the Covid-19 pandemic. And it hasn’t been easy for anyone. Around 62 per cent of Brits experienced anxiety last year during the first lockdown. None of us are immune to the effects of the way we’ve been living and working in the past year. And gas engineers have been truly heroic, at the front line of keeping people warm and safe, especially in the cold winter months. But it’s difficult to unwind from the pressures of the day in the way that we’re used to. We can’t meet up with friends and our loved ones easily, there may be financial worries from working less, and we may have been ill ourselves. We know that a big majority of gas engineers are sole traders or part of a very small company, which means that the day’s pressures can stay bottled up inside and not offloaded among colleagues and friends. In our feature this month on anxiety, we talk to gas engineers who live with the condition and who share some of their tips on dealing with it. There’s also information on some of the organisations that are there to help you if you’re feeling anxious or worried about your mental health – including MENTalk, an online community founded by tradespeople that encourages men to support each other to know that they are not alone.

e’d like to say a big thank you to everyone who took part in our recent reader survey: we’re grateful to you for letting us into the secrets of your working life. What you tell us about yourselves helps us to shape this magazine, making sure it’s relevant and useful to you and the work you do, and providing the technical, high-quality information you need, in whatever format you need it. Our survey asked a wide range of questions, the answers to just some of which are shown on these pages. It’s clear that the work you do is as diverse as you are, and Registered Gas Engineer will continue to make sure that our essential content – and the way you access it – reflects that.

REGISTERED GAS ENGINEER | GAS SAFE REGISTER NEWS

Kitchen fitter tried to cover up illegal and incompetent gas work A kitchen fitter has been given a suspended prison sentence after he admitted carrying out gas work illegally and faking the details of a registered gas engineer. Exeter Crown Court heard that Brian Squibb, from Exeter, trading as BKS Kitchens and Bathrooms, was contracted to fit kitchens, and signed an installer agreement giving the name of a Gas Safe engineer whom he would use for gas work. However, in summer 2019,

Technical Bulletin update Technical Bulletin 155 has been revised to include the revised HHIC Installer Guide: Condensate discharge pipe installation. You can read and download all Technical Bulletins by signing into your online account at www.GasSafeRegister. co.uk/sign-in

G3 unvented qualification certificates If you’re intending to notify unvented hot water cylinders that are connected to a heat-producing gas appliance, you’ll need to provide Gas Safe Register with a valid copy of your G3 Unvented qualification certificate. Gas Safe Register will only accept a certificate where the expiry date is no more than five years from the date of issue. Gas Safe Register will be contacting a number of registered businesses by email over the coming months to request a copy of engineers’ certificates. Please keep an eye out for the email.

Mr Squibb carried out the gas work himself at two properties in Exeter, falsely using another person’s name and registration number. He removed an existing natural gas hob, capped a live gas supply, and failed to check for gas tightness. The HSE investigation found that Mr Squibb had never been registered. However, after he completed the work, he produced documentation for the homeowners, falsely using a registered gas engineer’s

name and registration details. Brian Squibb of Elizabeth Avenue, Exeter, Devon, pleaded guilty to breaching regulations 3(1), 3(3) and 3(7) of the Gas Safety (Installation and Use) Regulations 1998 as amended. He was sentenced to eight months in prison, suspended for 24 months, and ordered to carry out 120 hours of unpaid work. He was also ordered to pay costs of £4,250. After the hearing, HSE inspector Simon Jones said: “Brian Squibb

undertook gas work, which he knew he was not registered to do. He then tried to cover up his unregistered and incompetent gas work by producing fraudulent documentation.”

REGISTERED GAS ENGINEER | AROUND THE INDUSTRY

Takeaway owner is served with suspended sentence A Birmingham takeaway owner has been given a suspended prison sentence and ordered to wear an electronic tag after he was found guilty failing to maintain the gas boiler at his business. Mohammed Shafique (59) of Newbridge Road, Birmingham, was found guilty in December 2020 at Birmingham Magistrates’s Court of not maintaining the boiler at Kin’s Crunchy Chicken, also in Newbridge Road. He was sentenced in January 2021. A gas engineer carrying out a meter exchange for a utility company reported the boiler installation to Birmingham City Council’s Environmental Health team in September 2018. He had found a large gap where the chimney/flue should have been

connected to the boiler, and disconnected the gas supply. Mr Shafique was served with Improvement Notices in October 2018, which required him to arrange for a competent person to connect the chimney/flue and service the boiler. The correct chimney/flue was fitted the following month. The council’s investigation found that the boiler had not been serviced for at least three years. Mr Shafique was unable to provide any servicing records, and said he had not tried to find a qualified gas engineer. Mr Shafique was found guilty of breaches of the Health and Safety At Work etc Act 1974 and the Gas Safety (Installation and Use) Regulations 1998 as amended. He was given a 20-week prison sentence,

ELECSA customers to transfer to NICEIC Certsure’s ELECSA brand is being retired from all its schemes, with customers transferring to NICEIC. Kevan Parker, managing director of Certsure, says: “Historically we have operated the two brands, both wedded to our core values of delivering technical excellence and raising standards. However, our assessment processes and the assessors who deliver them are the same. So, too, are the customer service and technical helpline teams that work behind the scenes. “We know that verifiers and consumers have 13 times greater

awareness of the NICEIC brand compared with all other electrical certification bodies, and we want to focus our resources and attention on just one brand.” The transition of all ELECSA customers will be completed by November 2022 but Kevan adds: “Customers who are registered with ELECSA will be contacted six weeks prior to their renewal date.”

suspended for 12 months, and a 12-week curfew. He was ordered to pay costs of £1,500. Philip Davis, chair of the city council’s Licensing and Public Protection Committee, said: “This incident shows what can happen if any business fails to maintain gas appliances in line with health and safety requirements. This could have resulted in serious or life-changing injuries. “Fortunately, the gas engineer recognised this serious fault before it caused any harm.”

Claim your £150 training reward with APHC APHC (Training) has 100 training rewards worth £150 each to give away to plumbing and heating companies during 2021. The registered charity runs the reward scheme every year to help safeguard the long-term professional development of the industry by incentivising plumbing and heating engineers to refresh their knowledge and gain new skills. The £150 reward can be used for a certificated course with a recognised training provider, such as APHC, BPEC, City & Guilds and all UKAS-approved ACS providers. The vouchers are valid in England and Wales and gas engineers do not need to be a member of APHC. Delegates can train remotely using Microsoft Teams for two hours a day for up to four days. At the end, they carry out an online assessment using a blend of long answer and multiple-choice questions and visual exercises. The 2021 course programme includes Legionella Cold Water Risk Assessment & Disinfection; Domestic Hot Water Storage Systems (Unvented) and Sanitary and Above Ground Drainage. www.aphc.co.uk/training-reward

Heat pump market ‘set to double in 2021’ Sales of heat pumps are anticipated to nearly double in 2021 to 67,000, according to a member survey by the Heat Pump Association. Around 35,000 heat pumps were sold in 2019, and the association says the near doubling of the market is a significant step in the right direction. The growth also aligns closely with the HPA’s 08 March 2021

roadmap to net zero, which called for 72,000 heat pump installations this year. The Heat Pump Association wants to prepare and upskill installers so they can recommend and deploy heat pumps at the scale required by the government’s net-zero ambition. The association outlined a new scalable route to becoming a heat pump installer in its 2020 report,

Building the Installer Base for Net Zero Heating. The route proposed begins with a technology-neutral, low-temperature heating course, before specialising in low-carbon technologies, including heat pumps. Phil Hurley, chair of the Heat Pump Association, says: “The near doubling of the heat pump market this year would be a substantial achievement. Our

members are committed to turning today’s forecast into a reality and have clearly backed this up with their advanced ordering. “The estimation of 67,000 heat pumps in 2021 shows the confidence from members of the HPA in delivering the scale-up of heat pumps that the Prime Minister’s Ten-Point Plan necessitates.”

Time to shine on World Plumbing Day The critical worker status of plumbing and heating engineers has changed the way people view the industry. On 11 March, World Plumbing Day will shine a light on how those in the trade have been on the front lines, risking contact with Covid-19 so that they can keep the public safe and warm in their homes. World Plumbing Day was created in 2010 to promote the vital link between good-quality plumbing, health, environmental sustainability and, increasingly, economic prosperity. The occasion raises awareness of the importance of plumbing and plumbers worldwide. Kevin Wellman, CEO of CIPHE, says: “It’s been a whirlwind of a year. Plumbing has sat at the heart of tackling the pandemic, from the clean water, taps and sinks we use to wash

our hands, to the sanitation systems we use to help stop the spread of viruses and bacteria. “In the latest lockdown, PPE-clad engineers have been the local heroes, fixing coldweather emergencies such as broken-down boilers and burst pipes, in very tough situations. “This World Plumbing Day, the CIPHE applauds the way our members and the entire industry have persevered through the past year. At the same time, we implore those in positions of authority to act upon the issues the Covid-19 pandemic has shone a light upon. “Our industry will have a huge role to play in supporting homeowners and businesses through a recovery, and those hero capes will be staying firmly in place for the foreseeable future.”

‘Plumbers are the trades people needed the most’ Plumbers were the most in-demand tradespeople in 2020, followed by electricians, according to research by Vanarama and Rated People. Almost two-thirds of the survey’s 1,000 respondents (64 per cent) said they called out a tradesperson in 2020, of whom 23 per cent needed a plumber, and 11 per cent an electrician. Spending more time at home during lockdowns and the rise in home working had made 52 per cent of people more aware of issues around them that needed fixing. The rise in demand for tradespeople led to some noticeable wait times, with 29 per cent of people saying they’d had to wait for longer than usual to book in a tradesperson’s time. 10 March 2021

National Grid Gas plc has been fined £4 million for failing to ensure its records were up to date relating to gas risers in some high-rise multi-occupancy buildings. Liverpool Crown Court previously heard that, in June 2017, the HSE requested information from gas distribution network (GDN) companies about their management of gas networks in high-rise multiple-occupancy buildings (HRMOBs). At the time, National Grid Gas operated the nationwide gas transmission system and the gas distribution systems supplying gas to around half the UK’s domestic and industrial gas customers, including the gas pipes in HRMOBs. However, in 2016 National Grid Gas sold part of its operations to Cadent Gas Ltd, including the activities to which the failings relate. HSE’s investigation revealed that the records that National Grid Gas transferred to Cadent when it sold its gas networks were incomplete. There had been no audits or reviews when the records issue came to light in December 2017. This meant that Cadent was continuing to inspect only the buildings on the existing database. Cadent’s management records were found to be incomplete: details about 769 buildings were missing, which meant that the gas risers in these HRMOBs had not been surveyed, inspected or had any routine maintenance for a number of years.

Additionally, the investigation found that National Grid Gas had failed to ensure that 112 HRMOBs had pipeline isolation valves (PIVs) so that gas to these buildings could be isolated in the event of an incident. As a result of this, HSE undertook a criminal investigation that considered the risk to which residents and members of the public were exposed. Enforcement notices were issued in April 2018 requiring Cadent to take remedial action. Cadent took appropriate action and complied with the notices by September 2018. National Grid Gas plc, of 1-3 Strand, London, pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc Act 1974 in November 2020. In February 2021, the company was fined £4 million at Liverpool Crown Court and ordered to pay costs of £91,805. After the hearing, HM principal inspector for HSE, Julie Voce said: “Our investigations found that people living and working in the high-rise buildings where the failings took place were not protected from the risk of gas leaks. “National Grid Gas did not have a robust system for recording the details of the gas pipes within these buildings. Opportunities arose where National Grid Gas identified data errors, but these were never satisfactorily acted upon, and opportunities to correct the situation were missed.”

Correction In our news story last month (February) about Kane’s new after-sales support, we stated that gas engineers in Northern Ireland would be able to send their FGAs to CalMet in Dublin instead of returning them to the UK. Of course, Northern Ireland is very much part of the UK: we should have said ‘mainland Britain’.

New regulator for safer construction materials A new national regulator is to ensure that the materials used to build homes will be made safer, the government has said. Housing Secretary Robert Jenrick says the regulator for construction products will have the power to remove any product from the market that presents a significant safety risk, and to prosecute companies that flout the rules on product safety. The move follows testimony to the Grenfell Inquiry that highlighted the dishonest practice by some manufacturers of construction products, including deliberate attempts to game the system and rig the results of safety tests, said Mr Jenrick. The regulator will have strong enforcement powers and will be able to conduct its own product testing when investigating concerns. The governent’s overhaul of regulatory systems includes the publication of a draft Building Safety Bill, and a new Building

Safety Regulator, which is already up and running in shadow form. Mr Jenrick said: “The Grenfell Inquiry has heard deeply disturbing allegations of malpractice by some construction product manufacturers and their employees, and of the weaknesses of the present product testing regime. “We are establishing a national regulator to address these concerns and a review into testing to ensure our national approach is fit for purpose. We will continue to listen to the evidence emerging in the Inquiry, and await the judge’s ultimate recommendation – but it is already clear that action is required now and that is what we are doing.” The regulator will operate within the Office for Product Safety and Standards (OPSS), which will be expanded and given up to £10 million to establish the new function. It will work with the Building Safety Regulator and Trading Standards to encourage

and enforce compliance. The government has also commissioned an independent review to examine weaknesses in previous testing regimes for construction products, and to recommend how abuse of the testing system can be prevented. It will be led by a panel of experts with regulatory, technical and construction industry experience and will report later this year.

Hot water sizing help The Hot Water Association (HWA) has launched a tool to help consumers and heating engineers choose the right hot water system. The online homeowner ‘hot water check’ questionnaire complements the HWA’s cylinder sizing calculator. Getting the calculation wrong can have repercussions for everyone involved, says the HWA: users run out of hot water or pay over the odds to heat water they don’t use; heating engineers get called back to jobs, and manufacturers get called out to unhappy customers. HWA chair Geoff Egginton says: “The questionnaire has been created to give consumers and installers logical and sensible advice on the type of hot water system they will need, based on their household usage.” www.hotwater.org.uk

Polypipe snaps up Adey and Nu-heat Drive off in an electric van with Baxi Baxi is giving one lucky gas engineer the chance to drive away in a brand new electric van. They will be able to get behind the wheel of a Nissan E-NV200 Visia electric van, to thank them for their hard work as they get back out on the road to keep heating Britain. There are a further 500 prizes, from £10 Costa Coffee vouchers to £30 Halfords vouchers. All you need to do is sign up to Baxi Works from now until Sunday 4 April and register at least one boiler. Every boiler registered during the campaign will also submit an entry, so the more registrations,

the more chances of winning. Existing Baxi Works members can enter by submitting a testimonial using the suggestions box on the dashboard of their Baxi Works account.* Dave Cook, residential sales director, UK & Ireland, says: “It’s been a rocky start to 2021, so we are keen to show our support for installers who continue to work hard to keep heating Britain, and help them make the year ahead a success. “We look forward to spreading a bit of positivity.” www.baxi.co.uk Terms and conditions apply.*

Polypipe is growing its presence in the heating and plumbing sector, and has scooped up two specialists – Adey and Nu-heat. The company aims to broaden its reach in climate and water management, with a focus on low or zero-carbon heating. Its CEO Martin Payne says: “Adey is a pioneer and market leader in the residential heating protection market, one of the fastestgrowing segments of the UK construction market, underpinned by a shift towards more energyefficient heating systems and regulatory tailwinds. “Like Polypipe, it has a strong track record of innovation and new product development, with the acquisition strengthening the proposition for our customers and accelerating Polypipe’s growth.” Adey CEO Matthew Webber says: “We are excited to be joining Polypipe and by the growth opportunities ahead. The

companies share a similar culture and philosophy, focused on delivering sustainable water and climate management solutions.” On buying Nu-heat, Martin says: “This acquisition will enable us to further develop our underfloor heating capabilities, and to develop new and exciting ways to integrate underfloor heating, heat pumps, and air-based climate management systems.” Nu-Heat managing director David Roberts says: “We look forward to being better positioned to deliver more sustainable solutions to customers and greater opportunities for our people as part of the Polypipe Group.” Polypipe paid £210 million to acquire Adey, and £27 million for Nu-heat. The management teams of both companies will stay with their businesses. www.gassaferegister.co.uk 11

School’s out for ever Jack Allen is not the first person to follow in his gas engineer dad’s footsteps. But, at just 16 years old, could he be the youngest ever holder of a Gas Safe ID card? Registered Gas Engineer find out.

hen we first tried to speak to Jack Allen, he wasn’t there. “He’s at college doing his oil exams,” dad Darren told us. In fact, over the past few weeks, Jack has completed his CCN1, as well as taking assessments in pipework installation and unvented cylinders. And when we got to talk to him in early February, he was expecting his Gas Safe ID card to arrive shortly. The past year has seen Jack juggling work with school, and the training and assessments he needed to become Gas Safe registered. His school allowed him

and Assessment in Maidenhead. “From what I’d heard from everyone else, they made it sound really, really hard. And it was hard – but it wasn’t as hard as everyone said.” Darren says: “He’s going to fly, I can see it. He’s eager and keen.” And dad has been the role model and the reason behind Jack’s decision to become a gas engineer. “I used to go to work with dad when I was younger,” says Jack. “I’ve been brought up in the trade. It’s something I’ve always looked forward to doing and,

“Jack may not have liked studying at school, but there’s no doubt that he enjoys learning what it takes to become a gas engineer.” to leave, releasing him to work when he was 15 in early 2020 – although he is still studying to make sure he will get his GCSEs in English and Maths. “I don’t really like it but I have to do it to get my results,” says Jack. “I always wanted to be hands-on at work. When I used to do engineering GCSE, I never liked doing the theory side, I just liked the practical side. I was doing work experience for one day a week, on a Thursday, and I kept asking if I could do that for more days.” Jack was combining work with going to school on Monday mornings until the most recent Covid-19 lockdown, and would have taken his GCSEs this summer, along with other Year 11s. Now he expects his exams to be replaced with predicted grades. He may not have liked studying at school, but there’s no doubt that he enjoys learning what it takes to become a gas engineer, putting together his portfolio and passing his assessments at Gasmark Training 12 March 2021

when I had the chance to do it, I did it.” He had already been working with Darren for a few years at weekends and during school holidays. “I’d get him drilling holes, sorting the van out, and getting the fittings sorted,” says Darren. “But he gradually progressed. When he was about 13 or 14, all I heard from the school was that Jack wanted to be a plumber.” Boilers and breakdowns Now, a typical day sees Jack working alongside his colleague Nathan Thompson on a variety of jobs, from boiler installations to fitting hot water cylinders, and dealing with breakdowns. “I’m starting to get to know it,” says Jack, and he is looking forward to the manufacturer training centres re-opening so that he can train on breakdowns for specific boiler brands. Next on the list is commercial qualifications – and this time he’s bringing his dad. “It will be the first time I’ve done commercial, so we’ll be learning together,” says

Darren, who used to be an electrician but switched trades some years ago. Jack isn’t the first young person that Darren has brought on in his company, which has apprentices working on the bathrooms side of the business, as well as in plumbing and heating supplies. But his confidence in his work does set him apart, and customers don’t usually realise his age. “They usually think I’m in my 20s, although some

customers ask and then they’re shocked,” he says. As soon as Jack’s Gas Safe ID card arrives, he’ll be able to work independently, one of the company’s team of eight gas engineers. But there’s still one more hurdle to get over before Jack can go out to jobs on his own: his driving licence – he’ll have to wait until he turns 17 in November before he can learn to drive. Then there just won’t be any stopping him. ■

Local Plumbers Heating & Plumbing in Gerrards Cross has eight gas engineers covering areas around West London, typically installing around seven boilers a week, says director Darren, who spends much of his time these days estimating and checking that everything has been done correctly. Darren has also added Local Bathrooms Design & Installation, and drainage specialisms, as well as a plumbing and heating supplies business. He works hard to bring through the next generation of tradespeople, with three apprentices in different parts of the business, and he makes sure that they get a thorough practical grounding. “You’ve got to inspire kids,” he says. “I’ve got one in the shop, so they learn all the fittings first. Then they go over to the bathroom side and do basic plumbing. And then they come to us on the heating side eventually.”

Look to the future, look to Blue Flame Navien Blue Flame – low NOx, future-proofed You don’t have to take the cover off to know what’s inside a Navien LCB700 oil boiler.

David Halifax was looking for the reason for a failed tightness test – and he found this soldered joint in the roof space. David made safe and replaced the section of pipework.

Severe corrosion and holes on top of the combustion chamber meant that this old balanced-flue boiler was no longer room sealed. Mark Webster has now fitted a new boiler.

This attempt at a chimney plume management solution incorporated its own excess condensate disposal system via the drainpipe. Ian Banks put the installation right.

Darren Keightley spotted a meter bracket shear bolt instead of a proper test nipple at the meter test point. He replaced the bolt.

Neil Tinsley was called to check a boiler installation and saw that this chimney had not been sealed on the inside or outside of the building. But worse was to come when he realised that the condensate pipework from the boiler was in copper. Neil made safe.

Birds will nest almost anywhere, include on top of this U6 gas meter, as sent to us by Murat Karakas. The nest was cleared so that Murat could carry out a tightness test.

Always check chimneys in voids, as illustrated by Simon Hobbs’s photo. Simon made the installation safe.

Industry Standard Update 102 The Gas Industry Unsafe Situations Procedure – IGEM/G/11 Date issued: 20 January 2021

This Industry Standard Update provides an overview and highlights areas of significant change in the recently published version of The Gas Industry Unsafe Situations Procedure – IGEM/G/11. Introduction On 15 January 2021, IGEM published a revision to The Gas Industry Unsafe Situations Procedure, IGEM/G/11(1) (Communication 1840). The revised procedure supersedes The Gas Industry Unsafe Situations Procedure, IGEM/G/11 (Communication 1819)(2), which has been withdrawn. IGEM/G/11The Gas Industry Unsafe Situations Procedure is owned and published by IGEM. The requirements of this revised industry Procedure come into effect immediately. To allow registered businesses time to implement the necessary processes and procedures and to carry out the necessary internal update training to reflect the technical requirements of the amended Procedure, Gas Safe Register will inspect to this version of the Procedure from 15 April 2021. However, this should not prevent businesses from applying the procedure sooner. The following is a brief overview of the amendments to IGEM/G/11The Gas Industry Unsafe Situations Procedure.

classify unsafe gas installations correctly. The general principles of the Gas Industry Unsafe Situations Procedure (GIUSP) may be: • Used as a guide to action in premises that fall outside the scope of GSIUR • Used in geographical areas not covered by the GB edition of GIUSP, including Guernsey, Jersey, Isle of Man and Northern Ireland. Section 2: Scope Clause 2.2 states that the priority for gas engineers when encountering an unsafe situation is to safeguard life and property. It is essential that gas engineers are able to identify gas equipment that presents a danger or potential danger and take prompt corrective actions to eliminate such danger.

General IGEM/G/11has been revised throughout to update terms, references to legislation and other standards.

Section 4: Competencies When applying the classifications used in IGEM/G/11, the competent engineer shall be able to justify their rationale based on the situation on site. The examples in this document are not intended to be exhaustive and/or definitive, and the final decision in applying classifications lies solely with the competent engineer on site, following their site-specific risk assessment.

Section 1: Introduction Clause 1.9 states that IGEM/ G/11has been drawn up by the gas industry in order to assist competent engineers in meeting their legal duties in accordance with the Gas Safety (Installation and Use) Regulations 1998 (GSIUR) as amended and associated Approved Code of Practice and Guidance, and

Clause 6: Dealing with unsafe situations Clauses 6.1(e) and 6.2.1(e) include guidance to: ‘Complete a “warning notice” which shall emphasise the words “DANGER DO NOT USE”. Regardless of the format used, obtain a signature from the gas user/ responsible person as both a record of receipt and

18 March 2021

understanding. Before leaving site, a copy shall be issued to the gas user/responsible person and you should keep a copy for your records. If no one is present, leave a copy on site to alert any future user to the danger.’ Clause 8: RIDDOR, unsafe gas work and theft of gas reporting Clause 8.3 has been revised to ensure consistency with current legislation and states that RIDDOR Regulation 11(2) requires registered gas businesses/engineers to report any gas fittings (including appliances and flues or ventilation used with appliances) that are dangerous to such an extent they have caused or are likely to cause: • Death • Unconsciousness • Taking a person to hospital due to the design, construction, manner of installation, modification, or incorrect servicing of the gas fitting that could or has resulted in an accidental leakage of gas, incomplete combustion of gas or inadequate removal of products of combustion of gas. This is commonly referred to as poor workmanship or design. A flowchart of the process is contained in Appendix 7. Clause 8.5 has been added to detail how and when to report under RIDDOR. Clause 8.6 has been included to provide guidance on how and to whom to report unsafe situations due to poor workmanship that are not reportable under RIDDOR. Clause 8.7 provides guidance around the theft of gas.

Section 9: Table 1 Table 1 contains examples of the types of situation that are ID or AR. The table is not exhaustive and individual circumstances may require different actions to be taken. Therefore, engineers shall exercise their engineering judgement and be able to justify their classification rationale based on the situation on site. Actions should be within their area of competence and, where there is doubt, seek further guidance. A header added to each table page details RIDDOR requirements to be considered. Revisions to Table 1 are opposite. Summary As previously stated, this Industry Standard Update is only a brief overview of the information contained in the amended standard. Registered businesses should be aware that they have a responsibility to ensure that they are fully apprised of all of the requirements of the whole published standard and its practical application.

The law, legislation, ACoPs What are the different types of law, and how are our industry standards developed? Gas Safe Register Standards Manager John Stirling has the lowdown.

as Safe Register frequently receives calls about the hierarchy of industry standards and how they should be applied. It’s important to note that Gas Safe Register neither creates nor enforces the standards. There are two types of law that create the framework for the regulation of health and safety: criminal and civil law. A simple workplace accident can result in both types of legal action. The table on the right summarises the two types of law and highlights some of the significant differences. Sources of law There are two sources that are relevant to the legal systems outlined above: Statute law and Common law. Statute law is made by Parliament and exists in the form of Acts, Regulations and orders. Common law is made by 20 March 2021

judges through the decisions they make and the precedents that these rulings set. You may have heard this referred to as the law of the land and it’s established by custom and practice. Statute laws, when introduced by the state, will mean that those who do not comply can be prosecuted by the state through criminal courts. Modern Acts of Parliament set out principles or objectives and use specific Regulations or Orders to implement them. The Health and Safety at Work etc Act 1974 (HSWA) is probably the most important piece of statute law, relating to health and safety in the workplace. Acts of Parliament (HSWA, for example) are ‘enabling Acts’, which means that they allow for the creation of health and safety regulations such as The Gas Safety (Installation and Use) Regulations 1998. Regulations

Criminal law

Civil law

made under an Act of Parliament are secondary, delegated legislation. Approved Codes of Practice (ACoPs) often accompany regulations and supplement statutory legislation such as Acts and Regulations.

ACoPs give expert interpretation on how to achieve the legal standard as outlined in the regulation that they accompany, and will usually give a clear indication of what is expected. Failure to comply with an ACoP is not in itself an offence.

REGISTERED GAS ENGINEER | TECHNICAL

and standards But if an ACoP has not been complied with, then it must be shown that alternative methods were used to achieve at least the same standard as the ACOP. Guidance such as Standard Documents and Technical Bulletins have no legal force but can be considered as best practice and can also be used to interpret legal standards. This tier of documents includes the gas industry standards. They are known as Normative Documents and are referred to as the Gas Industry Standards. These documents, in conjunction with any available manufacturer’s instructions, will be used by Gas Safe Register to assess compliance. Common law Common law is not recorded in the form of Acts and Regulations. Instead it is created when a precedent has been set by previous court cases. Where the

judge of a court case has made a reasoned decision, the reasoned decision sets a precedent that will influence the decision-making of judges in the future. Common law relies heavily on the principle of judicial precedence; the idea that judges in courts have to take note and follow the precedents set by a higher court. Gas industry standard development It is a common misconception that normative documents such as the gas industry standards are developed and published by Gas Safe Register. This is NOT the case. The gas industry standards used by Gas Safe Register are developed by the three current Standard Setting Bodies: • British and European Standards (BSI) • Institution of Gas Engineers and Managers (IGEM)

Inspections undertaken by Gas Safe Register When Gas Safe Register inspects work undertaken by registered gas businesses in Great Britain, Northern Ireland, the Isle of Man and Guernsey, in the first instance it will assess against the manufacturer’s installation instructions. Where these are not available or relevant, it will inspect against the criteria as specified within legislative documents and relevant gas industry standards. There will be some differences in application because of the differences in the individual legislation in different geographical areas. Due regard will be taken of the requirements of all appropriate guidance while conducting inspections. ■

• Liquid Gas UK (formerly known as UKLPG). The development, review and publication of these standards is managed by the Standard Setting Body. The body is supported by committees made up of volunteer gas professionals, who have a broad range of knowledge, expertise and industry experience. Various technical committees guide and advise on the development of new standards and, where required, the review of existing standards. They are usually reviewed and amended only where changes and developments in the industry need to be addressed. Gas Safe Register supports both industry and the HSE by being involved in various technical committees, but questions relating to any of the standards in use should be directed to the relevant chair of the committee for a response.

Getting involved in standard development If you think your knowledge and experience could benefit a technical committee, your involvement would definitely be valued and you can contact the relevant Standard Setting Body. If you can’t be involved on a technical committee, you can still comment on draft standards. Before standards are published, they are are always put forward for public and industry comment. It’s at this stage where most registered businesses can give their opinion as to whether they agree with a clause, and make suggestions. Gas Safe Register endeavours to keep the industry informed of the status of standards via the Legislative, Normative, and Informative Documents List (LNIDL). This document is reviewed quarterly and published in Registered Gas Engineer and in your Gas Safe online account. www.gassaferegister.co.uk 21

New guidance on LPG regulators N

ew guidance on regulators has been published by Liquid Gas UK. The guidance, designed for consumers, explains why regulators are necessary, as well as the importance of fitting over-pressure shut-off valves (OPSOs), and emphasises the importance of working with a qualified, registered engineer. LPG regulators reduce pressure so that the levels are in line with those required by appliances. The guidance sets out good engineering practice on regulator setting levels for domestic and commercial applications, the service life, and how to deal with malfunctions. Publication is timely as we head towards spring and summer, and more people dine outdoors

with BBQs and outdoor heaters. The guidance will also be useful to the leisure industry, including camping and caravanning, and outdoor food retailers. Richard Hakeem, director of Safety and Technical Policy at Liquid Gas UK, says: “Our latest Consumer Guidance Sheet explains in detail why regulators are necessary, and how they reduce the pressure of LPG so that the appliance can be used safely, while consumers enjoy the benefits of LPG during the summer season.” The guidance also highlights the regulator’s service life, when used correctly and stored in accordance with the manufacturer’s instructions. When regulators have been out of use for

a period of time – particularly over the winter months – they should be assessed for seasonal damage. It is recommended that regulators should be replaced if they are 10 years old or more. If a regulator is over 10 years old, it should be used in conjunction with an OPSO valve. Water entering the regulator from rain, snow and even sea spray can pose a serious risk. The vent needs to be positioned correctly to avoid ingress of water or contamination from dust particles, such as from brick mortar. If the regulator has been disconnected from its gas supply, it should be stored correctly so that it is not at risk of water damage or contaminates. If the regulator has been out of use for a long period of time, as is

likely with outdoor BBQ equipment, it is recommended that the valve is turned off completely until required. Most importantly, if it shows signs of water damage, leakage or general wear and tear, it should be replaced. ■ You can download the Consumer Guidance Sheet for Regulators at: www.liquidgasuk. org/domestic/consumerguidance-sheets

Government sets out its plans for Part L T

he government wants newbuild homes to produce lower carbon emissions starting this year to ensure the industry is ready to meet the Future Homes Standard by 2025. It’s published its first response to a two-part consultation on proposed changes to Part L (Conservation of fuel and power) and Part F (ventilation) of the Building Regulations. Its report on the Future Homes Standard consultation sets out energy and ventilation standards for existing homes and other buildings, and includes proposals to mitigate against overheating. The government says new homes are expected to produce 75-80 per cent lower carbon emissions compared with current levels. It has set out plans to

improve the energy performance of new homes, which are all expected to be highly energy efficient, use low-carbon heating, and be zero-carbon-ready by 2025. Heating and powering buildings accounts for 40 per cent of the UK’s energy usage now. It proposes that existing homes will be subject to higher standards, with a significant improvement on the standard for extensions, making homes warmer and reducing bills, and a requirement for replacement, repairs and parts to be more energy efficient. This includes replacing windows and building services such as heat pumps, cooling systems, or fixed lighting. Housing minister Christopher Pincher says: “The radical new standards will not only improve

“New homes are expected to produce 75-80% lower carbon emissions than current levels.” [the] energy efficiency of existing homes and other buildings but will also ensure our new homes are fit for the future, by reducing emissions from new homes by at least 75 per cent. This will help deliver greener homes and buildings, as well as reducing energy bills for hard-working families and businesses.” There will be stringent

transitional arrangements in place to provide developers with certainty about the standards to which they are building. The government has also announced a consultation on higher performance targets for non-domestic buildings which will mean they will be zero-carbon ready by 2025. The Future Homes Standard Consultation sought views on how best to improve the energy performance of new homes and was the first of a two-part consultation on Part L and Part F of the Building Regulations. The second consultation closes on 13 April 2021, and you can read it and respond at: www.gov.uk/government/ consultations/the-futurebuildings-standard ■

Tell them what you think

Include gas infrastructure in new-build

“The CIPHE welcomes the drive for energy efficient buildings and the path to net-zero carbon emissions. However, these new standards are being introduced rapidly, into an industry fighting the effects of Covid-19, problems with the supply chain and a training crisis. “To be successful, the industry has to work together, and support must be given to help deliver on government aims. It is vital that the industry makes their views heard on the path to net zero. Installers are at the forefront of environmental change and need to be involved in the process.” Kevin Wellman, CEO, CIPHE

“Vaillant welcomes the long-awaited response to the government’s Future Homes Standard consultation, and we’re particularly pleased to see the interim Part L uplift in June 2022 that seeks to produce 31 per cent less CO2 emissions compared to current standards. Although the existing housing stock is diverse and will therefore require different types of low-carbon solutions, there is no better time to build zero-carbon ready homes. “But the government’s timescales of further consultation in 2023, legislation in 2024 and implementation in 2025 leave very little time for the industry to find the best recipe for zero-carbon-ready homes. “Considering the recent 10-Point Plan and Energy White Paper recommending accelerating the use of hydrogen in heating, we would expect hydrogen

Adding TRVs is a step in the right direction “The most pressing element of this consultation is the changes to Part L coming out for existing buildings. Although there is nothing drastic in this aspect of the response, it is good to see confirmation on what we originally saw all the way back in 2005, where fitting TRVs on all radiators when replacing boilers was going to be made a requirement. “This was dropped back then because of the challenge of ‘consequential improvements’ that would have had to be made to the house at the time. “Now, however, TRVs are going to be a requirement, if technically and economically feasible – it’s fair to expect that it will be in most installations. “There is no question that the addition of TRVs to existing heating systems will help increase the efficiency of any system and is a small, but positive step in the right direction towards decarbonising domestic heating.” Martyn Bridges, director of Technical Communication and Product Management, Worcester Bosch

emission factors to be available within future versions of SAP as early as possible. This would encourage the industry to model the deployment of new-build hydrogen towns in the future. “We also call for the gas infrastructure to be included in new-build developments to give the consumer the choice between electric and hydrogen heating in the future. Furthermore, futureproofing all homes with low-carbon, low-temperature heating systems sets the foundations for savings, but there needs to be a heatsource-agnostic approach for new-build and existing homes. The focus should be on a 50°C mean water temperature, which will guarantee a robust design and lifetime savings.” Mark Wilkins, Training and Technologies director, Vaillant

REGISTERED GAS ENGINEER | LOW-CARBON HEATING

The decarbonisation opportunity Iain Bevan, commercial manager – heating & renewables – at Daikin UK, discusses the results of the first consultation on the Future Homes Standard, the best technology to aid decarbonisation of our housing stock and the opportunity this creates for heating engineers.

s the UK heads towards becoming net-zero carbon by 2050, the government has turned its focus to the Building Regulations, specifically Parts L (energy) and F (ventilation), in a bid to ensure all that new homes in England are built with sustainability at front of mind. As a result, and following initial consultations, the first plans under the new Future Homes Standard will see a ban on all fossil-fuel heating systems, such as gas, in new-build homes by 2025. Alongside uplifts in the energy efficiency requirements of other fabrication materials, the move should see the average home produce around 75 per cent less CO2 than one built to current standards. With heating and powering homes in the UK accounting for 22 per cent of all greenhouse gas emissions, the Future Homes Standard is a positive step towards decarbonising our

industry need to respond to ensure it is futureproofed and able to lead the way in the decarbonisation of our homes? Choosing the right technology is vital to enable the scale-up of installations of low-carbon heating systems to meet the increasing demand. While there is much discussion around the best solution, including the use of hydrogen, heat pumps are a well-established technology that can be installed efficiently and easily on a mass scale – probably one of the reasons why 70 per cent of those responding to the Future Homes Standard consultation believe they should play a role in achieving net zero. They offer significant energy efficiency benefits: a typical air source heat pump will produce 45 per cent lower carbon emissions than a gas boiler, and 59 per cent less than an oil boiler – a reduction of up to 43.5 tonnes

“Despite the many benefits of solutions such as heat pumps, consumer awareness and understanding of the technology remains low.” housing stock. However, if we are to be ready for the changes coming in 2025 and meet the 2050 net-zero target, the switch to low-carbon heating and preparation in our industry needs to start now. To help the industry get ready for the new regulations, the government plans to introduce an interim uplift in the current Part L standards by 2022. This will see a 31 per cent reduction in carbon emissions and takes advantage of technology such as low-carbon heating, as well ensuring an increase in building fabric standards. But meeting these targets will bring challenges in terms of the readiness of technology and the workforce. So how does the

of carbon emissions over the system’s typical 15-year life span per home. The benefits extend beyond energy savings: although the units should receive an annual maintenance visit to ensure optimum performance, they are much safer than conventional gas boilers that rely on combustion and need annual safety checks. Flexible friends Plus, with so many different options available for homeowners, heat pumps can be installed in almost any type of home. Whether it’s a luxury new-build, offering sleek design and smart technology, or a practical option to fit with a more traditional heating set-up, the technology

will provide flexibility while still delivering energy savings. Despite the many benefits of solutions such as heat pumps, consumer awareness and understanding of the technology remains low. This is something that needs to be tackled by the government and industry itself if the uptake of low-carbon heating solutions is to increase. However, choosing the right technology and bringing consumers on board is just one side of the story: ensuring those in the heating industry have the necessary skills and training to meet demand will also be key. Upskilling engineers The Committee on Climate Change has estimated that 19 million heat pumps need to be installed by 2050 to meet the government’s 2050 target. In 2018, heat pump sales in the UK were around 27,000 units. In order to decarbonise the heat supply, it’s thought this number will need to rise to more than 1 million annual installations by the mid-2030s and that a further 17,000 new installers will be required. We must continue to help heating engineers diversify and upskill, so they can take

advantage of the anticipated demand for installation and maintenance, which in turn will help futureproof their business. And the government’s Green Jobs Taskforce. launched in 2020, aims to ensure that a skilled pool of workers will help deliver net-zero by supporting people to transition into green jobs. The first plans announced under the Future Homes Standard and changes to the Building Regulations are just the beginning of our journey to a low-carbon future. However, it is one that is gaining momentum, and there are steps that can be taken now by those installing and maintaining heating systems to make the transition easier. Those who increase their understanding of low-carbon heating and train to upskill will protect their future and realise many opportunities. ■

Help on managing Last year, gas engineer Paul shared with us details of how his working life is affected by anxiety. We were overwhelmed by the response from readers, some of whom who wanted to share their own experiences.

veryone experiences anxiety at some stage in their lives, and it is often a healthy emotional response to stress that we encounter in our lives or a change in situation. But for the millions who suffer from anxiety disorders, or who experience extreme anxiety, it can be a debilitating condition, leading to panic attacks, depression and, in extreme cases, suicidal thoughts. Anxiety becomes a problem when it has an impact on our day-to-day life, causing stress and fear that can cause a significant physical and emotional effect on mind and body. People with anxiety frequently report high levels of distress, and feelings of uncontrollable worry that spiral out of proportion. This can cause people to avoid the situations that make them feel anxious, even if that has a detrimental impact on their life. Common physical symptoms of anxiety include feelings of extreme fear, feeling light-headed or dizzy, nausea, rapid breathing or hyperventilation, a fast, thumping or irregular heartbeat, and sweating or hot flushes. Anxiety can also cause panic attacks, which are a type of fear response where many of these symptoms build up at once, leaving the sufferer feeling as if they are having a heart attack, about to pass out, or even feeling that they are going to die. Panic attacks can be extremely frightening, especially if you have never experienced them before. What causes anxiety? No one really knows exactly what causes severe anxiety, although some research suggests there may be a genetic factor. Other theories suggest that anxiety disorders may be more likely if someone has experienced a significant stressful event or trauma. But exhaustion, stress, and long working hours are common triggers – something that the

26 March 2021

Covid-19 pandemic has exacerbated. Research by the Mental Health Foundation shows that 62 per cent of the UK population experienced anxiety or worry during the first lockdown in 2020, and more than one in 10 people in the UK reported having had suicidal thoughts or feelings during the final two weeks of June 2020.1 With many gas engineers

Engineers tell their stories Some readers have been keen to share with gas engineers their own experiences and tips on how they manage their own anxiety. Paul Davis from Manchester says: “I have always suffered with anxiety. It manifests in many ways and affects my sleep – I wake up at night worrying about potential problems, jobs I’m going to do, or have just done. I’m very critical of my own work, and it’s got to be a

“I may get anxious if I have to tell a householder their boiler is dangerous, but if anything happened by leaving their boiler on, the consequences could be far greater.” being sole traders or part of small businesses, and considering the ongoing financial uncertainties and restrictions caused by Covid-19, it’s no wonder that many are experiencing anxiety for the first time, or are finding it harder to cope with an existing mental health issue. Dealing with anxiety in the moment There are many different techniques that can help you manage anxiety, and some of the most common revolve around breathing and grounding techniques. A popular breathing technique that can work during an anxiety attack is the ‘54321’ method: breathe in deeply through your nose for five seconds, hold your breath for five seconds, then slowly breathe out through your mouth for five seconds. Then acknowledge five things around you that you can see, four things you can touch, three things you can hear, two things you can smell, and one thing that you can taste. Techniques like this can help because they act as a distraction from the anxiety, helping you refocus on what’s happening around you.

very high standard – I have to do my very best or I beat myself up inside. It’s a horrible feeling, and very hard to switch off. “Over the years, I’ve learned not to give people exact timings of when I’m going to arrive, because it would bother me if I was even a minute or two late. Instead, I say I’ll be there ‘between 9 and 10am’. I would also advise engineers not to book too many jobs in, as they invariably take longer than you think. I used to think ‘I can do six jobs in a day’, but if there was a problem on the second one, my anxiety would kick in and I’d start rushing things and making mistakes. “Working on your own can be difficult when you suffer from anxiety, because there’s no one to get a second opinion from. My anxiety makes me doubt my own skills, but manufacturers can help – their training courses give me knowledge. Also, if I’m nervous about something, I can ring their technical lines for a second opinion. “I’m a big believer in mindfulness, so when I’ve had a bad day, I take my mind off things by going on my exercise bike, or

spending time on a hobby – I’ve been teaching myself to play the ukulele. I’d also recommend a long walk at the weekend to relax. “I’d advise any engineer who suffers from anxiety to try not to beat yourself up. People think admitting to it is a weakness, but it’s not. I’ve seen lots of different tradespeople over the years, and I think the ones with anxiety are better workers, because they don’t want to let people down.” Meditation Gas engineer Paul Hirst experienced panic attacks in his mid-20s. He says: “I learned to meditate, started exercising, and found ways to live a more balanced life. I haven’t had any serious anxiety issues since. “Today, I teach people how to meditate and run online group meditation sessions. Meditating allows the mind to calm down and switch off, which helps you deal much more efficiently with problems and worries. I am a qualified hypnotherapist as well as a gas engineer, and have used hypnotherapy to help people who suffer with anxiety and stress. Hypnotherapists reprogram the subconscious mind and replace negative behaviours, thoughts, and emotions with positive ones. “Keeping fit, eating healthily, drinking lots of water and getting enough sleep can all help reduce stress and anxiety. “I’d also recommend writing down your problems and challenges, and prioritising them. List the solutions and actions that you are going to take. This will help prevent your mind from being overloaded and waking up in the middle of the night worrying.” A gas engineer who wanted to remain anonymous says: “When I am anxious, it affects my ability to concentrate, particularly if I am taken out of my comfort zone. My self-confidence can be quite low, and I get easily stressed. “The things that help me are to

anxiety at work Baxi and MENTalk Baxi partnered with MENTalk in 2020. MENTalk is an online community, founded by tradespeople, that encourages men to support each other to know that they are not alone. Together, the Baxi and MENTalk team have created useful resources online to support tradespeople, including information on suicide prevention and coping through lockdown. The partnership has also promoted a range of fun activities, online and on social media, to help connect the plumbing and heating community. Steve Smith, CEO of MENTalk, says: “As self-employed tradesmen ourselves, we’ve had our own personal journeys with poor mental health. We are very open to speaking about it, and hope to create a culture that makes it normal to do that. “It’s hard, and you might feel that you’re the only one going

As a gas engineer, there is a lot of responsibility on my shoulders. I may get anxious if I have to tell a householder their boiler is dangerous, but I have to remember that if anything happened by leaving their boiler on, the consequences could be far greater. “When I was at my worst, I gave up alcohol completely as this made the depression worse, and cut out caffeine as well. I take each day at a time now. Yes, sometimes it is like running through wet cement. If I gave into my feelings, some days I would probably never leave the house. “I have sought medical help, and was given anti-depressants that stopped the physical

symptoms of my anxiety – the rapid short breaths, heart palpitations and shaking hands. It did not help with what was going on inside my mind though, so I was referred for counselling. This helped me to recognise the triggers and see things differently.” More support for mental health There are many ways to manage anxiety, but it’s important to seek support and find ways to treat the source of the problem. Talking to a family member or someone you trust can be a great first step, as can talking to your GP. GPs can refer you for free counselling therapies on the NHS, and can also prescribe anti-depressants and other medications. One common therapy available through the NHS is cognitive-behavioural therapy

REGISTERED GAS ENGINEER | INDUSTRY ISSUES

What do future tradespeople want? The finalists of 2020’s Screwfix Trade Apprentice recently gathered to share their experiences of working in the trade. John Mewett, CEO at Screwfix, outlines some of their discussions and what they mean for the industry.

oday’s apprentices are tomorrow’s skilled tradespeople. Supporting them as they gain the expertise they need for a successful career, as well as better understanding the challenges and key issues they face, is vital if future generations of essential trades are to thrive. Key themes discussed by the finalists of the 2020 Screwfix Trade Apprentice competition included the importance of respecting mental health issues in the workplace, and a willingness to embrace new trends and renewable technologies to drive a sustainable future. The challenge of Covid-19 The health crisis has placed untold pressure on everyone, including tradespeople, as businesses and employees have had to adapt to the impact of Covid-19 in the workplace. The younger generation will be particularly hard hit by the pandemic fallout, with job opportunities under pressure as companies deal with the challenges they’ve faced. Despite such difficult times, every effort must be made to support the ambition of the next generation of gas engineers, so that demand for skilled tradespeople can continue to be met. Those at the beginning of their trade careers undoubtedly possess the drive and determination to succeed. This was abundantly clear among the inspirational talent that took part in Screwfix’s Trade Apprentice 2020 competition. Aside from their impressive technical abilities, it was also interesting to hear their views on crucial industry topics, which shone a light on how today’s apprentices – and tomorrow’s expert tradespeople – are thinking and feeling as 2021 begins to unfold.

28 March 2021

“The culture of bravado that is sometimes seen needs to be shed so that individuals can be themselves at work, and don’t have to conform to an old-fashioned stereotype that the younger generation simply does not recognise.” Raise awareness of mental health The apprentices hold a collective belief that, although mental health in the workplace has been increasingly debated in recent years, there is still much more to do to raise awareness across the trades. A prime example is the culture of bravado that is sometimes seen in the construction industry. The apprentices said this needs to be shed so that individuals can be themselves while at work, and don’t have to conform to an old-fashioned stereotype that today’s younger generation simply does not recognise. It is important that people feel able to talk to their colleagues, and are not afraid to share their experiences and feelings. More mental health resources and training should be made available across all the trades. The Time to Talk initiative is a great step forward, as is the availability of the Access to Mental Health Support Service for Apprentices from the government.

Learning renewable skills Apprentice gas engineers are focused on the innovations in technology that can help meet household demand for greener, more energy efficient products. The renewables sector was viewed as offering great career opportunities, backing up the widespread green agenda. The apprentices discussed wanting to work with consumers to deliver the environmental benefits that renewable solutions can provide. A combination of manufacturing innovation, and the increasing influence of new tradespeople entering the sector over the coming decades, should ensure real progress is made in the crucial take-up of the renewable solutions needed to tackle climate change. It should be made as simple as possible for tradespeople and apprentices to gain the TrustMark accreditation needed to carry out projects as part of the new Green Homes Grant scheme. In addition, the introduction of top-up training modules on the latest renewable energy products and services would also be a positive move to help all engineers upskill.

Many apprentices are already tech-savvy, and can bring a generational ability to support their employers with social media and online marketing, to make the most of the business opportunities presented by digital platforms. Our finalists also recognised the role that technology can play in helping them to learn new skills, with many of them regularly viewing trade ‘Day in the Life’ videos which helped to inspire them to take up a skilled trade. Based on the intelligence and passion demonstrated by these apprentices, the future of the trade is in good hands. It is vital that all parties across the construction trades, despite the current difficulties, provide the support and opportunities needed for our next generation of gas engineers to flourish. ■ www.screwfix.com www.time-to-change.org.uk www.remploy.co.uk/ employers/mental-health-andwellbeing/access-workmental-health-supportservice-apprentices

REGISTERED GAS ENGINEER | INTERVIEW

Breaking down barriers How is Viessmann planning to support gas engineers through the forthcoming energy transition, the UK’s steps to net zero, and the shape of new appliances? Registered Gas Engineer finds out.

as engineers who are thinking of moving into fitting heat pumps do face barriers: whether it’s the additional certification they need so that their customers can claim government grants and funding, or that they’re simply not familiar with the technology. Viessmann is keen to help them break down those barriers. Managing director Graham Russell says gas engineers are already more than capable of connecting a heat pump system hydraulically, as well as electrically if they are Part P qualified. In fact, he says, entry-level heat pumps have fewer hydraulic connections than a combi boiler. It’s system design and the MCS process that are the main challenges, he says. To help combat these challenges, the company has plans to support gas engineers through their heat pump journey, which it aims to roll out later this

guidance. Its Vitocal 100-A monobloc heat pump, launched last year, is designed so there’s no need for a complementary indoor unit and no F-Gas qualifications are needed to fit it. Connected world But the increased tempo of support for heat pumps doesn’t mean that traditional fuels are being left behind: new boilers are coming this year too. The upgraded Vitodens 100 will be first out of the blocks in spring, followed by the Vitodens 50 later in 2021. Both have the new operating system first seen in the premium boiler launched in late 2019. All models will use the same control logic and include WiFi and RF as standard, and the connectivity to enable them to work with the forthcoming ViCare control system, as well as connecting directly to the internet.

“Engineers will get real-time information about the boiler, along with a log of every action and event on the appliance since it was installed.” year. Graham says: “We want to provide gas engineers with all the background services, the system design software that complies with the MCS process and ability to provide pre-commissioning, final commissioning and sign-off.” The company is itself MCS certified and wants to create the framework and services so that engineers can install a heat pump, by supporting with the design and specification of the installation, through to precommissioning and sign-off. This means that the customer can be sure that the installation is MCS certified and so gain access to the Green Homes Grant or RHI. The company already provides training packages, both on general knowledge and understanding of heat pumps, as well as more product-specific

ViCare includes new components for the whole house ecosystem – including digital TRVs, thermostat and climate sensor. New apps aim to make life easier for engineers as well as their customers. The ViStart commissioning app enables gas engineers to commission the boiler remotely. “It’s a great solution for boilers that have to be fitted in awkward spaces,” says Graham. And the app can connect to the boiler’s WiFi instead of the home’s if required. “ViStart walks you through commissioning the boiler step by step, with a clear display and understandable logic, even if you’ve never commissioned one of our boilers before.” Added-value products are top of mind for Viessmann, and consumers aren’t being left out of

things. Vitoguide software comes with a free ViCare app for homeowners, providing WiFi connectivity and app control so they don’t need to buy an additional home hub. “Consumers will be able to connect smart controls [to be launched later in 2021], room thermostats, room sensors, radiator thermostats and control them through the app. It provides each individual room with its own time and temperature control,” he adds. For gas engineers, Vitoguide provides visibility of the status of all the connected boilers they’ve fitted. When customers register the engineer as their trade partner on the ViCare app, engineers will have real-time information about the status of the boiler, along with a log of every action and event

– such as settings being adjusted – on the appliance since it was installed. “Gas engineers can use the app to see the boiler status and potentially resolve an issue remotely without having to visit their customer. For example, the customer might have fiddled with their control and can’t get the heating on,” says Graham. “It’s all about giving people more flexibility and better value so they don’t have to buy extra hardware or devices: they can just connect directly to the boiler Not only do they have room control but they also get the status of the boiler through the smart control too. “We think it’s a bit of a game-changer.” ■

Partner Portal The Partner Portal is getting an upgrade too. Plans are under way to combine several existing benefits so that they’re all under one roof: training through the Digital Academy, product registration, the loyalty scheme and apps. “We’re adding all our installer added-value services into one place and simplifying the registration process so it’s a single log-on,” says marketing director Darren McMahon.

REGISTERED GAS ENGINEER | UNDERFLOOR HEATING

Make the right manifold choice Chris Ingram, founder of Continal Underfloor Heating, reveals what gas engineers should look for when they choose an underfloor heating manifold

he manifold is at the very heart of every underfloor heating (UFH) system. It connects hundreds of metres of pipework to the heat source and controls the distribution of hot water to each zone in the system so that it is always at the correct temperature and flow rate. Not all manifolds are created equal, however, and UFH installers should make sure they know exactly what each component does, and how it works, to make sure they choose the best-quality product. Each manifold has a flow and return side, with fill and drain loops on the ends. They can be made from different materials but we would always recommend avoiding welded manifolds, which have more stress points that could shorten their working life. The fill and drain loops each contain a bleed point, where a radiator key can be used to open up the valve if air needs bleeding from the system. You can also connect a hose to the loops if the system needs draining down completely.

Continal’s stainless steel HeatMax manifolds are individually pressure tested

plans change over time and you get called back to add more underfloor heating to an extension, for example, then you can simply unbolt the fill and drain loops, and join an extension

“Look for components that bolt together securely, with no need to use jointing tape or welding tools, both of which can increase the risk of leaks.” When you’re choosing a manifold, make sure the fill and drain loops are bolted on rather than moulded – again, moulded versions are at greater risk of leaks. Some manifolds feature automatic air vents, but these can leak over time, so we would advise using manual versions. Choosing a manifold with fill and drain loops that are bolted to the end rather than inside the manifold also helps to futureproof the system. If your customer’s

manifold to it. The flow gauges are critical to setting the flow of water through the system. These should be nice and clear, with printing that will stay readable even over time. Flow rates can be adjusted easily on most systems: look for actuators that enable you to turn each zone on and off using thermostats in each room. When installing UFH in a larger building, you may need more than one manifold: each manifold can

only control up to 12 zones. Your chosen manufacturer should be able to provide you with all the advice you need. The British and European standard for underfloor heating, BS EN 1264, requires that you must be able to shut off an UFH zone on both the flow and return side of the manifold, but a lot of cheaper manifolds that you can buy online don’t have this feature, so we would advise checking this carefully before you buy. Mix it up The mixer is responsible for taking the hot water from the boiler or other heat source to the pipes, after having blended the water to achieve the correct temperature. It then returns cooler water to the heat source once it has travelled around the system. The mixer has a temperature gauge next to it, so that engineers can see that the water is at the correct temperature level, and a circulating pump comes as

part of the mixer unit. Mixers also provide a simple fail-safe overtemp protection. If you’re connecting the UFH to a heat pump, a mixer may not be necessary. Some manifolds are easier to assemble than others. Look for components that bolt together securely, with no need to use jointing tape or welding tools, both of which can increase the risk of leaks. With so much choice of UFH, it can be difficult to decide whether to invest in a more expensive manifold that offers lots of additional features, or whether a basic mode will do the job. Researching and understanding how the different manifold components work, and what you need them for, means you you can make an educated decision on which type of manifold is best suited to the job at hand. ■ www.ufh.co.uk BS EN 1264-1:2011: Water based surface embedded heating and cooling systems

REGISTERED GAS ENGINEER | CONTROLS

The evolution of heating controls Rob Whitney from Resideo looks at how thermostats have changed since the invention of the damper flapper, and how the technology has evolved to play a crucial role in building the UK’s sustainable future.

he industry has come a long way since the invention of the damper flapper, which was created in 1885 to control coal fire furnaces. Back then, if a property was too cold, the device would lift the damper on the furnace so that air could fan the flames, and increase the temperature of the residence1. Over the next century, clocks were added to enable timings to be pre-set and, in the 1950s, dial thermostats appeared, including Honeywell’s famous round design. By the 1960s, hot water and heating could be controlled separately, and in the 1980s, the first thermostats with digital displays were launched. Advances in electronics enabled more functions, such as the ability to pre-set what times and days of the week the heating should be switched on. Fast forward to 2021, and not only are we able to change the temperature and time settings for our heating and hot water systems from anywhere in the world, room-by-room if required, but we can also adjust our heat source’s output automatically, according to internal and external conditions. Energy savings Today, being able to switch the boiler on or off according to pre-set temperature levels and timings is no longer enough to maximise energy savings and lower heating bills. More precise control of the boiler’s output, and how it adjusts to its surroundings, is becoming the norm to

optimise energy performance. Weather and load compensation, for example, modulates the flow temperature from the boiler based on external, internal and set temperatures. Some smart controls use weather control features to reduce the heating system’s energy usage based on the outdoor temperature, room temperature, and by learning the heat losses in each room. Interconnectivity Consumers expect to be able to adjust their heating systems without needing to stand in front of the thermostat. They can change the temperature from the comfort of their sofas, or access their thermostats from the other side of the world, using voice-activated digital assistants, or via an app on their smartphone or tablet. The availability of 4G from the late 2000s onwards helped to make the latter possible, so that users don’t waste energy heating their homes when they’re not in. No one knows exactly what the future will look like, but there is no doubt that new technologies will continue to have a significant influence on consumer demands and the evolution of the thermostat. Heating systems will need to move with the times too, and this will also impact on the development of thermostatic controls in the next decade and beyond. ■ https://hennepinhistorymuseumblog. wordpress.com/2018/10/03/the-story-of-thedamper-flapper/

Decarbonisation of heat Heat pumps were first marketed back in the 1980s, but consumer awareness of the technology remained low. Now, the heat pump market is expected to grow significantly over the next few years as the government develops policies to decarbonise heat. Thermostatic controls are evolving to ensure compatibility with heat pumps, and with the other equipment often used alongside them.

The evolution of the Evohome The Evohome from Resideo has seen several evolutions over the past decade. The grey screen of the 2010 version, for instance, gave way to a colour screen and gateway installation in 2014, before moving to Wi-Fi and gateway-free installation in 2015. The latest version has additional functions to reflect the increased interest in renewable energy sources and to increase the efficiency of the heating system. Resideo’s next generation Evohome can control heat pumps, on/off or modulating OpenTherm boilers, and also radiators, underfloor heating, and hot water cylinders. This way, homeowners who have had an Evohome installed to work with a boiler know it is futureproofed if they change their heat source in the future. Because the Evohome system can divide a property into a maximum of 12 zones, it can automatically adjust the settings for each zone according to their individual conditions. This means residents can feel just as comfortable in areas with poor insulation, or large windows, as they would in the rest of the house. The Evohome can also learn each zone’s heat capacity, via its advanced load scaling technology, to better control the boiler’s output.

Wise up on smart heating Demand for smart controls has grown in recent years as homeowners embrace the concept of a connected home. Remi Volpe, managing director at Drayton, reviews some of the main benefits that smart heating can offer.

he number of smart controls has grown significantly in recent years, with each control offering different features and benefits. They have become more accessible and easier to use, and are no longer just for tech-savvy homeowners. But many customers are still unfamiliar with the technology and are confused by the choice on offer: they look to their heating engineer to help find them the right solution among all the different options. Prevent energy wastage One of the key benefits of a smart heating control system is its ability to control the heating remotely. Many homeowners don’t have regular schedules, so smart controls enable the heating system to be adjusted from anywhere, as and when the occupier’s movements change.

energy wastage caused when heating systems are left on in empty homes. Multi-zoning Growing awareness of the importance of energy efficiency has helped homeowners become more conscious of how their heating works, especially when it comes to multi-zoning and the need to stop heating empty rooms. Previously, engineers would have used a low-loss header system to create different zones within a property, but smart heating controls and smart radiator thermostats have made this easier to achieve. Some smart heating controls can be paired with smart radiator thermostats to achieve room-toroom control. This means homeowners can control the time and temperature schedules for each individual room rather than

“Some smart heating controls can be paired with smart radiator thermostats to achieve room-to-room control.”

Some smart controls take this one step further by changing the heating schedule without any interaction from the user, using geofencing technology and integration with platforms such as ‘If This Then That’ (IFTTT). When a compatible smart control is linked to an IFTTT account, homeowners can download applets to set up triggers and actions that determine how the heating system should react in line with user movements. For example, when the homeowner leaves the home and the system registers that their smartphone or device is no longer inside, an away mode is activated to turn the system off. These functions can improve the home’s overall energy efficiency by preventing the 36 March 2021

the house as a whole, saving money on their energy bills by not heating empty rooms. Fitting a smart, multi-zone system in a typical threebedroom, semi-detached house could reduce energy usage by 20 per cent compared with a smart thermostat system. For a home with an average annual bill of £875, this could save £175 per year. The Wiser system, for example, can allow for up to 32 devices to be paired to create up to 16 individual zones. This also means that additional radiator thermostats can be added later if required. Radiator thermostats can be retrofitted on to most existing radiator valves, keeping installation times to a minimum.

Some heating controls have also been designed to provide users with detailed energy saving information, helping them understand how their heating system is performing and how small changes can improve its efficiency. Plan for the future As we look for carbon-neutral ways to heat the 23 million homes in the UK that currently rely on gas boilers, it is expected that electric heating methods, such as

heat pumps, will become more widely adopted. Smart heating controls will play an important role in maximising their efficiency too. Different technologies will be able to talk to each other within the same system, using the open protocols, such as OpenTherm, that are found in most smart controls. This will help ensure interoperability between technologies, enabling heat pumps to modulate and achieve optimal performance. Heating engineers are ideally positioned to help make heating systems across the country work far more efficiently as we move towards a more sustainable future, by being aware of the benefits that smart controls can offer and communicating them to their customers. ■ wiser.draytoncontrols.co.uk

Keeping connected – and safe Smart controls can help energy efficiency in commercial buildings, but it’s important to make sure that they stay secure, says Pete Mills, Technical Operations manager for Bosch Commercial & Industrial.

mart internet-connected control systems have a lot of benefits for buildings of all types. And the pandemic crisis has highlighted the advantages of remote access, reducing unnecessary visits to commercial buildings and providing reassurance that systems are operating well – from a distance.

the Internet of Things (IoT) have become more widely available. Many of today’s domestic boilers come already fitted with smart controls. Control of the system through apps is convenient, with a connection to the boiler along with clever modulation of system. Modulation ensures that the boiler runs only at the output required to

“It’s a good idea to have a basic undertanding of security in case your customer askes you about the security of their controls.” Commercial heating systems were early adopters of internet connectivity through Building Management Systems (BMS) and have been part of this revolution since the days of dial-up modems. As we begin to address the challenges of decarbonising heating in buildings of all sizes, smart internet-connected controls will play their part in maximising energy efficiency. It’s more important than ever to ensure that energy efficiency is a central aspect of facilities management. Smart controls will play a part in this. Being able to control and monitor the heating system means that issues or anomalies can be identified early on, helping to resolve potential problems and ensuring that the building’s efficiency can remain at a high level. Heat can be one of the biggest culprits when it comes to wasting energy, but making sure the system is as efficient as possible, and that only the required amount of heat is generated through good control, could reduce energy wastage. This is true of domestic properties, albeit at a smaller scale, where smart homes and

heat the room to the desired temperature, and ultimately makes the heating system more efficient. Staying secure With the growth in IoT comes risks for the unwary of malicious attacks to vulnerable equipment. One such case was highlighted in 2017, where a large number of schools’ heating systems were vulnerable to hackers. Equipment had been procured and installed by people who were simply not aware of the potential risks. This situation is not uncommon and many of us are likely to be complacent about internet security in our own homes. So what should we look for when choosing internetconnected heating system controls? For those who work in the commercial and industrial sectors, there are some key processes and protocols that reputable manufacturers of IoT equipment will follow: •B efore the release of equipment, all the critical points known and highlighted by OWASP (Open Web Application Security Project) should be specifically checked by the manufacturer

• Established security specialists should have already conducted PEN Tests (comprehensive internet security penetration tests) that look for critical vulnerability • All data is stored on secure servers that are classified to high standards, and the manufacturer complies with strict laws about how this data can be used • Regular software updates are available and implemented to keep systems up to date against the latest threats • The equipment IP gateways have additional firewalls • Equipment has individual activation codes • User log-in via an SMS security code, sent independently to the user’s phone. These key elements should be the minimum level required for standard commercial applications that have no particular security concerns. However, where there are higher security risks, dedicated VPN routers will provide an additional level of protection and can

give further peace of mind. Ensuring these elements are in place will give the building the benefits of connected controls combined with the lowest level of risk. This means that lower-cost solutions can be used to control complex heating systems. Off-the-shelf solutions help engineers to meet the needs of heating systems with multiple heating and hot water circuits, by using plug-in modules that can be configured to precise needs. Boilers and heat pumps can be sequenced to meet heat loads through equipment that is affordable, bringing remote access within the budgets of smaller plant rooms. As demand for controls continues to increase, we could see the heating controls used in commercial properties filtering down into our homes. Those who work in their customers’ homes are probably less inclined to consider this sort of security focus but it’s a good idea to have a basic understanding in case your customer asks you about the security of their controls. ■

‘ With more people, conversion could take just four years’ What would it take to change all the existing gas appliances in the UK to run on hydrogen? Chris Goggin of Rinnai UK looks some of the logistics involved in conversion.

national roll-out converting the UK’s energy resources to zero carbon is needed for if the UK is to be completely decarbonised by the year 2050. A vast amount of work needs to be planned, undertaken and completed in a national effort that lacks living experience in this unfamiliar process. Homes across the UK must transition to hydrogen and initial approaches being considered have outlined a three-step structure for the domestic conversion process: the initial survey, pre-conversion preparation work, and the conversion itself. The first step – the survey – offers no real challenges. The survey will involve an assessment on all pipework and gas appliances in each property, lasting one to two hours. There are no concerns other than selecting and training a competent workforce to carry out this preliminary phase. The pre-conversion preparation work is where turbulence is first encountered. Anticipated complications focus on the accessibility of copper pipework. Some pipework is certain to be behind concrete and disappear down into ducts. Material degradation of copper pipework and surrounding areas is another anticipated area of difficulty: if large sections are too damaged to continue functioning, pipework will have to be fully replaced, adding more time and effort. Because of this, further 38 March 2021

surveys focusing on the condition, age, and type of house could follow to approve which homes are more compatible with the hydrogen transition process. The third step is the conversion itself. The difficulties that each domestic conversion encounters will directly correlate to the problems each presents during the preparation work, such as concreted or hidden pipes. Replacing a boiler will take no more than a day; hobs, fires and ovens, half a day each. Two-anda-half days of labour have to be carried out in each house across the UK to refit appliances that gas engineers are not yet trained to complete. Taking into consideration that the conversion itself is reliant on favourable property preparations, current estimations on time per property may change or fluctuate, depending on each individual property and the safety standards of its existing infrastructure. People power Issues regarding the workforce to carry out the energy transition process are still being discussed. There are 23 million homes currently powered by gas, a major source of the UK’s harmful emissions. To service these homes, there are currently 130,000 individual engineers spread across 74,000-plus employers, all of whom are Gas Safe registered, and 80 per cent of whom hold a domestic core qualification. Engineers will have to undertake and pass an

additional qualification to assist in the conversion effort. A further workforce of 100,000 will be needed to support these engineers. This workforce is yet to be assembled and, when subsequently amassed, training needs to be provided. If the conversion process is to rely solely on current gas engineers, it is estimated that the energy transition roll-out could take 16 years to complete – still well within the 2050 decarbonisation time limit set by the UK government. Factoring an extra 100,000 people, the conversion process could be carried out in as little as four years. The conversion process is reliant on two areas: primarily, what is found in the completed preparation work for each property, and, second, the availability of trained engineers and support staff to complete the work. The national roll-out will spread out regionally. This enables engineers to be concentrated and trained on site, as the region being worked in continues its conversion. A large number of support workers will also accompany the engineers. A further effort is required in directing a mass media blanket of information to inform the public about the benefits of hydrogen energy consumption; possibly before, during, and shortly after the conversion process; the content of this effort must be written, edited, re-written, printed

and distributed across multiple media platforms, with consistent information. We can do it From 1967 to 1977, the UK adapted from Town gas to natural gas: 40 million appliances belonging to 14 million people were converted. Yet this was completed by engineers operating at a time where knowledge and general expertise were not as advanced as they are by today’s standards; so the national roll-out of hydrogen is entirely feasible and possible. Current plans have specified several problems that are anticipated to have an impact on every stage of the national energy transition process, notwithstanding the initial survey. A vast measure of work has to be organised, authorised and executed before 2050. The size of the task is substantial and will involve hundreds and thousands of people across multiple sectors, both public and private, working in unison to deliver a national energy conversion. The task is huge, the workforce yet to be discovered, and the science and preparations that support the energy conversion are still not 100 per cent focused on one shared direction of action. Once these issues are confronted and simplified, the national roll-out of energy conversion can begin, turning the idea into reality. ■ www.rinnaiuk.com

REGISTERED GAS ENGINEER | THERMOSTATIC MIXING VALVES

Hot water system safety Hot water systems that are misaligned or managed incorrectly can cause problems ranging from Legionnaires’ disease to an increased risk of scalding. Richard Harvey, commercial director for Plumb and Parts at Wolseley, looks at the important role that TMVs have to play in keeping people safe.

t’s never been more important to make sure that our hot water systems are safe to use. More than 100 cases of Legionnaires’ disease were reported in 2020, according to Public Health England. Raising the temperature of stored water to above 60°C prevents the growth of the legionella bacteria – but also increases the risk of scalding. Thermostatic mixing valves (TMVs) use temperature-sensitive elements to blend hot and cold water to a temperature that safeguards against both legionella and scalding. It’s not a legal requirement to fit a TMV in existing bathrooms but it will help to safeguard your customers. Fitted to an outlet, TMVs prevent temperature disparities: mixing water is automatically

controlled by an internal thermostat to enable hot and cold water supplies to blend to a safe temperature. When installed correctly, TMVs maintain the predetermined temperature even if the water pressure fluctuates when other appliances are being used. If either the hot or cold water supply is cut off, the mechanism shuts off the valve automatically. Before installing TMVs, inspect, clean, descale and disinfect the strainers and filters to ensure there’s no build-up of dirt. Cleaning the valves periodically will also ensure correct flow so that the pre-set temperatures are achieved. Check the water temperature that flows through the TMVs, making sure the valves are at

least 50°C after one minute of the water running, and 20°C on the outside after two minutes. Choosing the right solution for the right job Different TMVs suit different applications, and there’s a balance to be struck between hygiene, comfort, aesthetics and budget. TMV2s are commonly used in a domestic setting, and they’re designed to work with water pressure of 0.1-1.0 bar and 0.5 bar-5.0 bar. However, in hospitals and healthcare environments, TMV3 valves are used as TMV2s do not meet the NHS requirements. Commercial applications require period inspection, cleaning and testing of TMVs. NHS D08 standards state that TMV3 valves

must be tried and tested every six to eight weeks once installed. Checks include a thermal element endurance test, a hot spike test, a response on temperature adjustment check, a stability test and a fail stop valve check. If TMVs are not checked, they are ultimately non-compliant and no longer suitable for use. Duty of care Both Legionnaires’ disease and scalding can have a severe impact, not just on the lives of vulnerable people, but on the NHS in additional treatment. Installing TMVs provides a solution that prevents the outbreak of disease and reduces the risk of scalding. wolseley.co.uk/tmv

REGISTERED GAS ENGINEER | RADIATORS

Radiators fit for the future How will radiators fit in a low-carbon heating future? By looking to the future and building on the past, says Stelrad.

ne of the key components of most heating systems in the UK is the radiators that share heat around the home. The range of radiators and the thinking behind their design has grown and deepened over the years: major design changes around 20 years ago saw better-designed water channels, and new ways of reducing the amount of water required to flow through while

reducing the amount of metal that came into contact with that heated water to share more heat, more effectively and more efficiently around the home. Stelrad head of marketing, Chris Harvey says: “Over the past couple of decades, the race for more efficient heating systems has been paramount in the industry and we’ve seen the arrival first of combi boilers and then of condensing, modulating boilers; the development of far better heating controls, energy efficient pumps and a wider range of more effective radiators. “The development of lowertemperature heating systems, using renewable heating appliances such as heat pumps, has given us another challenge, but it’s one we have risen to and are able to respond to effectively.

However, the key point to remember is that radiators are all compatible with all heating systems – traditional and renewable – when sized correctly.” Much thought has gone into the latest radiator developments and it’s all to ensure that radiators are fit for the future – able to continue providing the levels of heat needed to keep people comfortable in their homes. Stelrad has provided a heat-loss calculator and radiator sizing tool for many years, so that heating professionals can size the radiators correctly in every room, even making automatic calculations for the type of construction material, and the number and size of windows and doors. Chris says: “By thinking

ahead, preparing for the changes we see coming and talking to the people we work with about what they need, we have been able to provide a comprehensive solution that will see low-temperature heating systems delivering the heat and hot water that people require. “We have the products and we have the support in the form of training and CPDs that cover every aspect of the move forward into the new approach to heating in the UK that will undoubtedly be with us more quickly than we realise.” ■ Stelrad makes more than 2 million radiators a year in Mexborough, South Yorkshire. www.stelrad.com

REGISTERED GAS ENGINEER | COMPETITION

Competition Win with Danfoss Danfoss is offering one lucky reader the chance to win a TPOne room controller and 15 of its new RAS-B2 radiator packs.

WIN

alancing domestic heating systems just got easier and faster with the RAS-B2 Danfoss Dynamic Valve. Unlike other thermostatic radiator valves (TRVs), which only act as flow limiters, the latest addition to the Danfoss TRV family features a differential pressure controller. This ensures that pressure drops over the valve remain at a constant level, so that the flow through the valve is maintained at both full (winter) and partial (autumn/spring) loads. Pre-setting of the desired flow is done on the valve rather than on the lockshield – which could save you up to two hours of valuable working time. You can now make sure a system is correctly balanced in a fraction of the time it would usually take. The new RAS-B2 is specially designed to enable fast and simple hydronic dynamic balancing. And to make life even easier, the pioneering TRV is also featured on the Danfoss Installer App. The app helps you calculate, record and document the correct flow and subsequent setting for each radiator on your smartphone or tablet. Currently the RAS-B2 is the only 100 per cent pressure independent valve demonstrating a constant flow in all TERMS AND CONDITIONS
