FROM THE EDITOR

Comment

T

here’s a distinct sense that people have been waiting with bated breath for the government to hurry up and publish its long-awaited Heat and Buildings Strategy.

There’s already been a lot of speculation – some informed and some not so much – about what it might contain. But the government has already indicated that big changes are coming to the way we heat our homes in the future, and much of it does not involve gas.

What’s not so clear right now is whether heat pumps will be mandated, and in what scenarios, and when; or whether the government has listened to those who have been championing the role that hydrogen could play in decarbonisation.

And what part could hybrid heat pumps play?

They look and feel to consumers like a familiar boiler, and can be fitted in a similar way. They can be seen as a natural stepping stone on the path to net-zero 2050, and could have a valuable role to play.

It’s likely that the strategy will be published some time after we’ve gone to press on this issue, but we’ll be making sure we delve into the detail – and what it means for you – as soon as we can, online and in print.

Engineers give their feedback on virtual inspection pilot A

round 50 gas engineers have taken part in a trial of virtual inspection events.

From the comfort of their own homes, they joined an online classroom to undertake their inspection and gave their feedback on the process to Gas Safe Register afterwards.

And an overwhelming majority – 97 per cent – said they would be happy to complete an inspection virtually in the future.

As part of the pilot, they had carried out an e-learning module two weeks before the inspection. Then on the day they used their tablets or laptops with a webcam to log in securely via a link sent to them in advance

by Gas Safe Register.

Their ID cards were checked

and identity confirmed and then they started their knowledge check, a set of 30 multiplechoice open-book questions.

Most gas engineers said they found the system easy to access: 68 per cent said they either had no challenges setting it up or had only minor issues that they could resolve themselves.

Almost all (92 per cent) said they felt that the process went smoothly or worked well overall, from getting ID confirmed to undertaking the knowledge check. Just 13 per cent said they needed support during the knowledge check, all of whom were happy with the support they then received.

The virtual classroom aimed

would be happy to complete an inspection virtually in the future

to mirror the experience of a group inspection event, in which gas engineers attend a half-day inspection session, often held at a hotel in their area.

Gas Services Director Bob Kerr says: “We know that taking part in a virtual inspection event could save gas engineers time and money. There’s no travel to a venue, and it takes less than an hour to do, so they’ll lose less of their working day.

“And best of all, they can have their inspection from the

comfort of their own home. After they’ve left the virtual classroom, they can go and carry on with their day.”

The trial was a pilot to assess how a virtual inspection could work in the future and doesn’t replace routine inspection for some engineers. But in any future virtual inspection events, Bob says, “we’ll review the results of the knowledge check and assess whether gas engineers have passed or failed their inspection. If they have

failed, we’ll get in touch with them and arrange a face-to-face inspection.”

Gas Safe Register is now analysing the results of the pilot scheme and the feedback from the gas engineers who volunteered to take part.

“Seems a positive step for reviewing the knowledge of engineers but they would need to be computer literate.”

“Very good. It’s great that you can print off and see every question afterwards to pinpoint knowledge gaps or misinterpretations.”

“It was an overall good experience and enjoyable.”

“Good as a supplementary resource, but not a substitute for real-life interaction.”

Get ready for Gas Safety Week It’s well and truly summer, and that means one thing – Gas Safety Week is just around the corner. Preparations for the industry’s biggest gas safety initiative are well under way, with an updated supporters’ toolkit to help you join in.

As in previous years, the gas safety squad will be leading the campaign to make sure that people, their families and the communities in which they live and work stay safe from the dangers of gas.

Gas Safe Register is busy working on its plans for the week and putting the final touches to the supporters’ toolkit.

The toolkit helps you get involved and show your support online, through social media and

in print and contains logos, banners, images, leaflets and posters, pre-written social media updates and gas safety articles for your own website or that you can share with local news and community organisations.

There’s also a quick kit, which contains some key materials to get you up and running quickly if you’re pressed for time.

As always, gas engineers are at the very heart of Gas Safety Week, and when you pledge to support, you’ll be joining thousands of others to talk about gas safety with one unified voice, helping to keep your customers safe.

And being a part of the

13-19 September 2021

campaign can help you raise the profile of your own business too. You can: • Show your social responsibility and help to protect your customers and save lives • Use the free materials in the toolkit in your customer communications, online and in your social media

• Improve awareness of you and your business – all supporters will appear on the Gas Safety Week website.

You can pledge your support at www.GasSafetyWeek.co.uk but if you supported last year, there’s no need to do so again: you’ll automatically receive the 2021 toolkit when it’s available. www.gassaferegister.co.uk 05

REGISTERED GAS ENGINEER | GAS SAFE REGISTER NEWS

Dealing with complaints and concerns The most recent Open Channel by Gas Safe Register was a facilitated discussion about complaints and concerns – both those made by consumers and those from registered businesses about work they’ve found. Here we look at how the Register deals with concerns and at some recurring themes.

concerns received per month from consumers

to Gas Safe Register.

If the inspector wants to follow up any individual matters with the registered business, they will arrange this separately.

What are the most common concerns?

Many concerns are about different aspects of boiler installation, says Alistair, including missing paperwork, non-completion of the Benchmark checklist, fault codes and noise.

But the most common concern is from people who haven’t received their Building Regulations certificate because it’s been sent to the registered business and not to them directly.

Some concerns can be avoided when there’s clear communication between the gas engineer and their customer, says Alistair. For example, when there’s a delay on a job or it’s not going as smoothly as expected, explaining what that means for your customer, and the anticipated timeframe, can help to avoid misunderstandings and concerns being raised.

Gas Safe Register’s Technical Team also receive calls from consumers. It’s often about simple things such as queries over the installation of the condensing pipe or powerflushing, says Technical Support Manager Carl Bannister.

But it can also be because they want to double-check what their gas engineer has told them – for example, if a gas hob can’t be

Raising a concern about competence Under recent changes to RIDDOR, gas engineers can raise a concern to Gas Safe Register over gas work they think is unsafe and has been carried out by another registered business but that doesn’t meet the criteria to report under RIDDOR. Just log into your online account, choose Raise a Competence Concern and fill in the form. The Technical Team will contact the business concerned, and arrange for an inspection of the work when required. It’s important to note that you will be asked for your own contact details and those of your customer when you raise a concern for competence about another business so that the system is not open to abuse. ■ www.gassaferegister.co.uk/ engineer/resource-hub/ raise-a-competence-concern

3 ways to help minimise complaints 1 Make sure you show your Gas Safe ID card to highlight your professionalism 2 Explain the work you’re going to carry out at the first opportunity, and keep your customer informed of progress 3 Make use of the industry documents and standards available to support your engineering judgement.

fitted where they want it to be.

Gas engineers know the reasons why they’re working in the way that they do – making sure that their work complies with the manufacturers’ instructions and regulations – and spending some time talking these factors through with your customer is a great way to help them have confidence in your expertise, says Carl.

Ç

s a gas safety registration scheme, you might imagine that many of the complaints that the Register receives are about gas safety. But that’s not always the case. In fact, many are not about gas safety at all: they might be contractual disputes or sometimes they’re about related plumbing issues rather than gas work itself.

And that’s just one of the reasons why the Register now refers to concerns rather than complaints.

Whatever the concerns, the Register has a formal process for dealing with them. Because they’ve usually been reported online, the first step is to doublecheck the information that has already been provided – is there enough to start investigating?

Customer First Lead Alistair Pearson says: “We may need to contact the consumer to get a bit more information: we might need more precise detail about the appliance or perhaps the registered business that they’ve referred to.”

This is the information gathering stage, where the concern is assessed, and validated that it is about gas safety – not about an ancillary issue such as a problem with a radiator that was installed as part of a heating system.

If an inspection is needed, this will be organised by the scheduling team, who arrange with the consumer for an inspector to visit.

The gas engineer will also be invited to the inspection, if their customer agrees.

Following the visit, Gas Safe Register completes a report detailing any defects that need to be corrected, along with a date by which the work should be completed. The report is sent to the customer, the registered business and, if appropriate, to the landlord.

When the defects have been remedied, the registered business must fill in the defects completion form confirming this and return it

Jail for dangerous gas fitter who used fake IDs A fake gas fitter whose dangerous work put lives at risk in the North-east of England has been sent to prison for three years.

Dean Blues from County Durham advertised his services on various social media sites from September 2016 to December 2017, using false names, several telephone numbers and at least three bank accounts to evade detection, Newcastle Crown Court heard.

HSE, prosecuting, said his poor and illegal workmanship had put lives at risk in seven homes, exposing residents to

the risk of carbon monoxide poisoning, asphyxiation, fire and explosion. The homes, in Houghton le Spring, Washington, Blaydon on Tyne, South Shields, Hebburn, Spennymoor and Middlesbrough, contained a catalogue of problems.

In one home, the pipework sleeve from the gas meter box was not sealed correctly, the flue assembly had not been sealed internally or externally to the structure of the building, the appliance’s combustion chamber was missing a retaining screw and another was partially tightened, which meant that a

Products of combustion were spilling into home A Newcastle construction company director has been given a suspended prison sentence after his work on a home extension left the gas boiler venting products of combustion inside.

Newcastle upon Tyne Magistrates’ Court heard that a mother and her two children suffered from the effects of carbon monoxide poisoning during building work in April 2018 at their home in Lichfield Avenue. HSE, prosecuting, said David Coulson, from Newcastle upon Tyne, had left the boiler in use during the building work even though the supporting wall to which it was secured had been removed and the extension built around it. The boiler was perched on top of a breeze block with the flue venting inside so that products of combustion were entering the home.

The family and their dog all showed symptoms of CO poisoning, and the children were given oxygen at hospital. The homeowner raised her concerns with Mr Coulson as she could see fumes spilling into the property but he denied that this was the case.

Mr Coulson, director of Coulson Constructions North East Ltd, arranged for the boiler

proper seal was not formed.

In another, there was a gas escape and its flue fell apart when poked. Several other homes had experienced gas escapes and contained work that was Immediately Dangerous.

Mr Blues had never been Gas Safe registered and was not competent to work on gas.

HSE had been investigating him in Scotland previously.

Dean Mulholland Blues of Annand Way, Newton Aycliffe, pleaded guilty to 24 breaches of the Gas Safety (Installation & Use) Regulations 1998. He was sentenced to three years in

prison and was disqualified from being the director of a company for 12 years.

Speaking after the hearing, HSE inspector Jonathan Wills said: “If anyone has had any gas work carried out by Mr Blues, I urge them to ensure that the work is now checked by a registered Gas Safe engineer as soon as possible.”

Fitter ignored Prohibition Notice not to work on gas

to be moved and the flue routed to outside but this was not carried out by a registered gas engineer. A Gas Safe Register investigations officer found that the installation was At Risk even after the boiler had been moved.

David Coulson of Gofton Walk, Newcastle upon Tyne, pleaded guilty to breaching Section 37 and Section 20 (2)(j) of the Health and Safety at Work etc Act 1974.

He was sentenced to 12 months in prison, suspended for 24 months, told to carry out 250 hours of unpaid work and ordered to pay costs of £5,200.

Speaking after the hearing, HSE inspector Paul Wilson said: “Construction work can and must be planned properly to ensure the health and safety of those potentially affected throughout the building project.”

A Dorset gas fitter has been given a three-year community supervision order for carrying out gas work illegally, breaching a Prohibition Notice, and using expired Gas Safe Register credentials.

Bournemouth Crown Court heard that Dean Coslett, trading as Dorset Boiler Company, fitted gas boilers in a number of properties in Dorset between December 2017 and April 2019 while he was not registered.

Mr Coslett did not fit the boilers in line with the manufacturers’ instructions and left flues incorrectly fitted and unsupported. He used his expired Gas Safe registration details on paperwork, says HSE. In September 2018, HSE had served Mr Coslett with a Prohibition Notice banning him from undertaking gas work while he was not registered. However, he breached this Prohibition Notice and continued to work on gas.

Dean Coslett of Sevenoaks

Drive, Bournemouth, had been registered in his own right previously and as an engineer for a registered business.

Mr Coslett pleaded guilty to breaching Regulation 3(3) and 3(7) of the Gas Safety (Installation & Use) Regulations 1998 and Section 33(1)(g) of the Health and Safety at Work Act etc 1974. He was sentenced to a three-year community supervision order, ordered to carry out 200 hours of unpaid work and 30 days of offender rehabilitation work. He was also ordered to pay £900 compensation to a number of homeowners for the sub-standard work he carried out in their homes.

Speaking after the hearing, HSE inspector Simon Jones said: “Dean Coslett undertook gas work, which he knew he was not registered to do and flagrantly breached an order prohibiting him from undertaking gas work whilst he was not registered.” www.gassaferegister.co.uk 09

TB 055 updated Technical Bulletin 055 Duties of landlords – has been updated to include a new question and answer.

No other material changes have been made.

Q10. Is there any leeway in the renewal date of the safety check?

The renewal date is the date by which the next safety check must be carried out. There can be no overrun of this date. However, Regulation 36 now allows for ‘MOT-style’ checks that can be carried out up to two months early, while retaining the renewal date.

For instance, a landlord’s gas safety check that is due for renewal on 12 April 2021 can be carried out any time between that date and 12 February 2021, and the renewal date of this check would be 12 April 2022. The last two safety checks must be retained for this to come into effect.

• To read Technical Bulletins, log into your online account at www.GasSafeRegister.co.uk/sign-in

Correction

Our June article Landlord’s gas safety checks and records, included information about what defects should be listed on the LGSR, and stated: “If the appliance is supplied with LPG, you should notify the supplier, and in any other cases you should notify the transporter.”

We would like to clarify that this action should only be taken when an Immediately Dangerous situation is identified and the responsible person refuses permission to disconnect the appliance/installation, in accordance with Gas Industry Unsafe Situations Procedure (GIUSP), known as IGEM/G/11.

James turns his garden into Covid memorial Lancashire gas engineer James Anderson has transformed his front garden into a public memorial to those who have died during the Coronavirus pandemic.

James runs not-for-profit company DEPHER, which hit the headlines in 2019 after news spread about his work providing free plumbing and heating repairs to elderly and disabled people.

The memorial garden

features a wishing well, benches, a dedication plaque, and pots so that people can come and plant flowers. James hopes it will give people a place to sit and remember their loved ones, or just to come together and reflect on the past year.

“A lot of people have lost their lives,” he says. “As a community, we need to keep that sense of community spirit and never forget what has happened. The garden is there

Get hybrid-ready with free Daikin training Daikin is providing free training on hybrid heat pumps to help gas engineers tap into this market.

Available until the end of 2021, the one-day training aims to give engineers the skills and knowledge to offer hybrid heat pumps to homeowners looking to start their decarbonisation journey.

Hybrid heat pumps combine a gas boiler and heat pump, working together to provide heating and hot water, and Daikin says they’re the ideal replacement

for a combi boiler as a first step towards renewable heating.

Iain Bevan, commercial manager, Heating & Renewables, says: “Hybrid heat pumps are an attractive solution for installers and homeowners who want to go green, combining the power of a heat pump with the familiarity of a boiler. Their installation, commissioning and service is similar to traditional boilers.”

The manageable upfront cost of a hybrid system is one of its key selling points, as is the installation process, which minimises disruption to customers.

The company says hybrid technology is best suited to smaller homes in urban areas that are likely to have a combi boiler, and where the building fabric is not energy efficient enough to be heated by a fully renewable system. www.daikin.co.uk/ hybridtraining

to say to everyone, ‘come in and take a moment to remember’.”

Throughout the pandemic, DEPHER has supported its local community, spending more than £100,000 on food, PPE and utility bills for those in need, and even paying funeral bills.

DEPHER is continuing its work but James says the donations on which it relies have fallen by 90 per cent due to the pandemic. www.depher.co.uk

Free support service from MCS A free scheme support service from MCS (Microgeneration Certification Scheme) is designed for gas engineers who want support to get their renewables work off the ground and who are thinking about becoming certified.

The service offers one-to-one advisor support, workshops, masterclasses and sharing of technical information.

The team offer online, telephone and face-to-face support for gas engineers who are working towards becoming MCS certified, as well as technical support and guidance on how to comply with MCS requirements.

Julian Hodgson and Steve Webster cover the UK, meeting with gas engineers to offer free guidance and support.

As a former trainer, technical

assessor and installer of renewable heating, Julian has experience of MCS from both sides of the fence, and is an apprentice-trained heating engineer.

Steve is a heating and renewables engineer, a member of the CIPHE and EngTech with the UK Engineering Council.

He has run his own MCScertified heating and renewable energy business installing PV, heat pump and solar thermal technologies.

MCS CEO Ian Rippin says: “We are working hard to remove barriers to entry for installers, having recognised the challenges faced when attempting to make the pivot into the renewables sector.

“The launch of this free scheme support offering from MCS signals the start of this.”

Travis Perkins sells plumbing arm for £325 million Travis Perkins has sold its plumbing and heating divisions to HIG Capital, an alternative investment firm, for £325 million, with the sale expected to be completed shortly.

City Plumbing Supplies (CPS) and Plumbing Trade Supplies (PTS) have more than 350 branches across the UK and Ireland, alongside specialist online

outlets including the Underfloor Heating Store, Direct Heating Spares, PlumbNation, and National Shower Spares.

HIG says it will support the company in its transition to an independent company and accelerate expansion in the UK and Ireland.

P&H CEO Dave Evans says: “The sale to HIG is great news for

P&H and its stakeholders. We are recognised as a market leader across many of our businesses and the categories they operate in, and I am very excited to work with the team at HIG to capitalise on the enormous potential for growth.

“We are well positioned to push forward with our plans for growth by developing more

customer-focused propositions delivered by over 3,000 dedicated team members.”

Tobias Borkowski, principal at HIG Europe, says: “We believe that the company, as a freestanding enterprise, can better serve the individual needs of its customers, and rapidly expand its trusted relationships with suppliers.” www.gassaferegister.co.uk 13

Plea for more time to transition to UKCA mark More time is needed to transition construction products to the new UKCA mark from the EU’s CE mark, say industry organisations. Without it, they warn that the industry could come to a standstill.

The UKCA mark is intended to replace the CE mark by the end of this year but Actuate UK, the engineering services sector body, wants an extension of the transition time to avoid delays and allow all products to be tested and accredited.

The problem with the limited transition period is being exacerbated by the lack of UKCA-approved bodies and available capacity in current

certification bodies, as well as product-testing facilities.

If any UK-made or imported products that need to show these essential features cannot display a UKCA mark by the end of 2021, this will leave manufacturers and gas engineers, clients and the public dealing with serious quality and contractual issues. In some product categories, 64 years’ worth of retesting will be required, according to some industry estimates.

For example, most radiators will not be able to be sold legally in the UK from 2022 without a new test certificate. Isaac Occhipinti, head of External

Affairs at the Manufacturers Association of Radiators and Convectors (MARC), says: “There is only one test laboratory in the UK, which has a limited capacity for testing. Even with a heroic effort, they will only ever be able to test a very small percentage of radiators currently legally on sale in the UK. “It will be impossible for all products to be tested by the 2022 deadline. The industry now faces the reality that the majority of radiators on sale in the UK will be without a ‘valid’ test certificate, in a few months’ time, and therefore unable to be sold legally.”

Organisations across the

NICEIC tightens entry and assessment criteria

CO Research Trust: the new name for the Gas Safety Trust

NICEIC and ELECSA are changing their existing assessment processes and future enrolment criteria.

One of the most significant changes is in the new applicant process, from 1 September 2021, which will effectively close the short-course entry route for new applicants.

“The 2020 Electrotechnical Assessment Specification update is a significant step forward for the entire industry,” says John O’Neill, NICEIC and ELECSA’s director of Technical Excellence. “For many years now, there have been calls from

contractors and industry to tighten entry criteria, and [this] announcement does just that.”

Existing NICEIC and ELECSA registrants will also see changes resulting from the EAS update.

In line with more stringent requirements, assessors will need to see more detailed evidence in areas such as ongoing CPD, adequate supervision of employed persons and appropriate levels of insurance, depending on the work undertaken.

The Gas Safety Trust is now known as The CO Research Trust, to provide a more accurate reflection of the work it carries out.

Baroness Finlay has become the charity’s new chair of the Board of Trustees.

“We fight CO exposure through funding scientific research as we believe that this will make the greatest difference. The new name more accurately conveys the focus of our work,” says Baroness Finlay. ”The CO Research Trust is entering an exciting new phase, where the focus of attention is firmly upon understanding the mechanics of CO poisoning,

Intouch From the editor: Our May feature about dyslexia and how it may be more common among gas engineers certainly struck a note with readers. We had deliberately mis-spelled dyslexia on our cover, to illustrate the real-life experience

Please send your letters, which may be edited, to editorial@registeredgasengineer.co.uk.

of some people who live with the condition – and we acknowledge that this treatment did not go down well with some readers.

Some people found it in poor taste, which certainly was not our intention.

But we know that the article has really got people talking openly about dyslexia and encouraged them to share their own experiences with others.

Just some of the responses we received are below.

I couldn’t do what I do without dyslexia I have just read the article, Working when you have dyslexia.

I fully endorse what was written.

I, too, find that the difference that dyslexia makes for me in how I think is a real advantage to me and enables me to trace faults almost instantaneously.

This ‘gift’ enables me to see in my mind the whole assembly in its entirety and how each part interacts with other components.

I can see how these symptoms would be related to each part in the working assembly.

As a result, I can often see maybe four possible failures that would cause these symptoms and a quick test can eliminate maybe two or three possibilities. This whole thought process is almost instantaneous and it’s intuitive, so even I can’t

often explain how I have made the determination.

Because of how my mind works, I do have an appetite to understand any mechanism completely but there are many devices or components where it is not possible to dismantle so that I can discover how it works, and I find that a bit frustrating.

Very often manufacturers do not provide sufficient details and the fault-tracing flow charts in the manual are often incomplete, poorly thought through or non-existent. Instruction books are often full of many words but lack logic and the information needed is fragmented.

I think dyslexia is a gift and I could not do what I do anything like as well without it.

I do sometimes tell my

customers that I am dyslexic and I get a variety of responses: some seem disturbed and concerned that somehow this makes me ‘disabled’ and look worried that they have let a disabled person loose on their precious equipment.

This is usually short-lived, though, when I then explain how it enables me to be much more capable. It often also uncovers their own hidden dyslexia or that of a family member, and sharing the differences of each other’s dyslexia can be quite refreshing and liberating.

My school experience was similar to Paul’s and is a sad and painful memory for me, but my Precision Engineering apprenticeship was quite different – my school exam

I’ve dealt with it in secret Having a form of dyslexia has created a number of challenges for me in my life from my school days in the 60s and 70s. This article was brilliant and heartwarming to read.

I have had to deal with this in secret most of my adult life, but when mandatory assessments

were introduced, it created obstacles for me with regard to reading sentences or phrases and determining what was asked or said – but if someone read it to me aloud I could fully understand.

I made my local assessment centre aware ‘privately’ of my situation a number of years ago,

and they have been very professional in assisting me with the additional challenges.

I’m now in my 60s with my career coming to an end and the article was uplifting for me. I am very pleased that this is being brought to people’s attention.

Walter Montgomery

results were 2 per cent in physics at school compared with my apprenticeship exam of 98 per cent in engineering science.

Cleary the problem with physics at school was not the subject matter but the exam.

Running my own business for the past 19 years has been great but also has its own challenges relating to the dyslexia. Many of the organisational aspects are made more difficult because my mind is not organised in a sequential manner and so using a non-sequential mind to organise my work sequentially is almost impossible. But my wife does have a sequential mind and so I rely upon her heavily with her book-keeping and organisational skills to complement mine.

Christopher Dolley

Disappointed with wall of text I was really excited to see an article about dyslexia, a really important and interesting topic!

Very disappointed to turn to a wall of text, which obviously hadn’t been written or presented with dyslexic people in mind.

In the UK, gas engineering is a heavily regulated trade, with the tradespeople having to undertake apprenticeships and regular training, the difficulty of

Was [your cover line] a deliberate play on the spelling to reflect the subject matter or simply poor proof-reading on

Why add chemical soup to clean heating systems?

I refer to the article in the May issue of Registered Gas Engineer about the new Part L revisions regarding water treatment. Once again, the chemical manufacturer lobby has got its way and the regulations totally ignore the

most effective way of protecting heating systems.

Can any of these peddlars of snake oil tell me why system water that has the correct pH value, low oxygen content and low conductivity needs a chemical soup added to it which,

Time to review EU language

Water treatment turmoil

Your answer to Frank Chandler’s question [Letters, What’s up with Chimneys?] goes a long way towards explaining why this country needed to leave the EU. Surely we should review all the rubbish that was introduced just for the sake of doing so.

Then a flue can remain a flue and a chimney remain a chimney.

It’s time to accept that the majority of technicians know what they are talking about and will not being changing. And it’s time those in charge reviewed their inane ideas and moved on, leaving the language and understanding of things alone.

Jonathan Davies

Having gone through the requirements for the water treatment that must be carried out when installing a new boiler, servicing or carrying out maintenance to a boiler or heating system, I find myself very disappointed. I say this because I believe this will be the fastest way to lose work from new customers, plus cause long-term damage to small servicing and maintenance providers.

My experience when entering the homes of new customers tells me this is never going to work for the majority of them.

I have already tested it out on a couple about this unexpected cost and it did not go down well.

Turning up on the doorstep for the first time to service or carry

in many cases, will adversely affect these figures?

They also mandate the fitting of a system filter. This is treating the symptoms rather than the disease: a clean system does not need a filter. Money would be far better spent on fitting

out maintenance is one thing, but it’s another to then test the heating water and tell them that it is not to the standard required (about 70 per cent of jobs) and that I will need to flush it out (probably via a powerflush) before I can put more inhibitor into the system. This will cost the customer significantly more money than just a service.

While some customers will tolerate this huge cost increase above the service or breakdown cost, most will just ask me to leave and there will be no way to enforce the powerflush. We all know Building Control cannot enforce these regulations. The only person who is going to lose out is the registered gas engineer. Furthermore, this may

As usual, it seems that those who shout the loudest get their way and the science is totally ignored in favour of selling unnecessary products.

Mike Walton

deter people from having their boiler serviced for fear of having to have a powerflush.

Then once the public realise they can stop you from taking a water sample as they own the property, there will be nothing you can do.

I am disappointed as this has nothing to do with gas safety: it only benefits the water treatment manufacturers.

We won’t see any improvement to the carbon footprint that can be attributed to system cleaning.

We won’t be able to enforce it and lots of installers will just say the water was OK on the day.

Is 100% biogas the way to reach net zero?

I’ve been Gas Safe registered for about six months and I read the Gas Safe magazine and see different viewpoints on a greener Britain. I am very concerned how little people understand what is eco-friendly – mostly electric boilers and cars.

Our gas boilers run off the grid, to which we do add biogas, which is a carbon-neutral fuel source.

Wouldn’t it be more economical for the government to create a

100 per cent biogas grid so that most of Britain won’t have to get a new alternative-fuel boiler?

The problem we have is that currently we only have two alternatives – electric and hydrogen.

Electric does discriminate against the poor and working class. How are they supposed to afford a new, greener boiler when they cost a lot to install and run?

It’s the same with electric cars.

The problem we have is that it’s expensive to run off the grid.

Wealthy people can invest in air source heat pumps and electric cars. But the electricity grid runs two-thirds on fossil fuels: how is this zero-emissions?

I think a 100 per cent biogas grid should be used. Using government and some rich businesses, we could have more bioplants and more maize farms.

What would be a good idea to

help the gas grid is more accessible grants for anyone who has a less efficient boiler to upgrade to a modern condensing gas boiler.

I want a greener world. I see the reality of this isn’t easy as every country is different, and it has to be profitable in order to work. But if my generation doesn’t act, then the earth will be uninhabitable by the 22nd century.

Low pressure and under-sized pipework Low gas pressure at gas appliances due to undersized pipework is the topic of many contacts to Gas Safe Register, both from registered businesses and members of the public. Here, Technical Officer Gary Aymes looks at some of the causes and what steps to take.

P

ressure loss is an inevitable occurrence when designing an installation and needs to be considered. Pressure is lost because of the frictional resistance of the components used in the installation pipework that are exposed to gas. The amount and size of pipework and fittings used in the installation all contribute to a certain amount of drop in pressure across the system.

When designing an installation, the size of installation pipework required should be determined from the maximum gas rate of the appliance(s) to be connected, and an allowance may need to be considered for any future developments or extensions in the property.

To meet requirements and minimise pressure loss, an understanding of what can affect this can help gas engineers when they are designing the system. This includes the gas consumption of the appliance(s), the length of pipework required, the number and type of fittings, and the type and bore of pipework.

All these factors increase the frictional resistance to the flow of gas, which, in turn, increases the pressure loss.

BS 68911 states that, for natural gas installations, the design pressure loss between the outlet of the primary meter installation and the point to be connected to any appliance inlet shall not exceed 1mbar at the design installation maximum flow rate: for LPG installations this figure is 2mbar.

22 July 2021

How to calculate gas pipework size in a domestic property When you’re quoting for a new gas boiler, you must survey the property before you start work to decide the most suitable boiler position, taking into account the layout of the property and your customer’s needs. With the position of the boiler established, you must work out the route that the gas pipework will take from the meter to the appliance position.

Once the route has been decided, you must calculate the pipe sizing to serve the gas

the nearest measurement above what is needed. You should then follow the table across, where the pressure loss per metre for each pipe size is listed.

By multiplying this number by the equivalent length, you can see which pipe size will ensure that there is no more than a 1mbar drop in pressure across the pipework installation.

The example shown opposite is an installation with a gas meter and a single appliance and the figures used in the calculation are taken from Tables A.1 & A.5 of BS 6891. The appliance is a boiler of 29kW net.

“Once the pipework route has been decided, you must calculate the pipe sizing to serve the appliance with an adequate supply of gas.” appliance with an adequate supply of gas. To do this calculation, you need to carry out a pipe-sizing exercise using either the tables provided in BS 6891, or appropriate training materials.

First, measure the route of the pipework, allowing the appropriate additional lengths for fittings. This will give you what is called the ‘equivalent length’.

This is the total length of pipe that you should use in your final calculation.

Once you have your equivalent length, use Table A.1 from BS 6981 (or equivalent) to work out the required pipe diameter.

To do this, you need either the heat input or gas rate of the appliance(s) in the property. If the total heat input is not listed, use

If there is a cause for concern Existing installations

If you find potential problems with pipework or pressure issues, then further investigation is required. It could be that the pipework has been sized correctly but there is now a blockage, or there may be upstream network issues affecting the supply pressure to the property.

In this instance, contact the manufacturer of the appliance(s) affected for guidance of the safe levels to which their appliance will work. Using this, your engineering judgement and guidance from the Gas Industry Unsafe Situation Procedure2, you must assess whether the readings are affecting the safe operation of the appliance.

Why can’t the design pressure loss exceed 1mbar?

As an example, the gas engineer installs an appliance on existing pipework but does not ensure that the pipework has a maximum 1mbar pressure loss, in accordance with BS 6891.

This installation pipework is losing 5mbar, with the working pressure at the meter outlet at 20mbar, and therefore the appliance would seem to be receiving 15mbar, which is within the manufacturer’s specifications.

The engineer assumes that because the manufacturer’s instructions state that the appliance will work safely with a minimum of 14mbar, then this is acceptable. However, the pressure in the network at peak demand reduces to 20mbar and the meter absorbs 4mbar, leaving 16mbar at the meter outlet. The 5mbar loss across the pipework now leaves only 11mbar at the appliance – below the manufacturer’s minimum.

This means the appliance may not work in accordance with the manufacturer’s instructions. The engineer in attendance must risk assess the installation and follow IGEM/G/11, the Gas Industry Unsafe Situations Procedure, if the appliance is working unsafely. ■

(1) Using Table A.1 from BS 6891, read across from equivalent heat input the section of pipework is feeding (or next figure up if yours is not listed). If you look at 15mm pipe in the 29.47 kW Net column (the correct column for this installation), you can see that you get a loss of nearly 0.5mbar per metre, and if you go to 28mm pipe then you could run nearly 50 metres of pipe. Therefore, 22m pipework is most appropriate, giving you a drop per metre of 0.0769 mbar.

(2) Using Table A.5 from BS 6891 work out equivalent pipe length, which is the pipe length plus an additional allowance for the fittings

used. In this installation there are 4 elbows (7m of pipe + 2.4m for fittings (4 x 22mm 90 elbows) = 9.4m). Therefore, the equivalent length of this installation is 9.4m.

(3) Multiply the equivalent pipe length (9.4m) with the pressure drop per metre of the appropriate pipe size (0.0769 mbar), which gives you the pressure loss across the installation. The pressure loss across the system using 22mm pipework will be 0.72286 mbar (9.4m equivalent length x 0.0769 mbar drop per metre).

Are you ready to pay Registered Gas Engineer looks at how the government’s Making Tax Digital initiative will affect you and how to prepare.

E

very business and all selfemployed traders must submit records of their sales, profits and expenses to HM Revenue & Customs (HMRC) each year, so they can calculate and pay the correct taxes. This process is now changing with the introduction of the Making Tax Digital (MTD) initiative.

HMRC has set out its ambition to be one of the most digitally advanced tax administrations in the world, modernising the tax system to make it “more effective, more efficient, and easier for customers to comply”.

First introduced through the Finance (No.2) Act 2017, MTD is a key part of this goal, which HMRC says will make it easier for individuals and businesses to keep on top of their tax affairs.

Under MTD, businesses and

records will reduce the amount of tax being lost.

MTD is being rolled out in stages. VAT-registered businesses with a turnover above £85,000 have had to comply with this legislation since April 2019, and 2022 will see the scheme expanded to cover all VATregistered businesses. Sole traders and self-employed people will have to comply from April 2023.

What records do I need to keep?

The government says it’s not asking VAT-registered businesses to keep any additional records, but rather that everything must now be kept in a digital format to reduce the risk of manual typing or transposing errors.

The VAT records you must

“Every trade business shoud be considering their plans for MTD: don’t get caught out at the last minute and plan early so that your finances are in check.” sole traders will need to keep their VAT and income tax records digitally, then use compatible software to send information to HMRC. Submissions must be made every three months, although any taxes due will need to be paid yearly.

After each quarterly update, you’ll be able to see a year-todate calculation of how much tax you owe. The government says this will help to reduce errors, cost, uncertainty and worry, so that you can be confident you’ve got your taxes right.

It will also help HMRC to reduce what it calls avoidable mistakes – simple errors that affect the amount of tax collected.

The latest statistics1 show that these mistakes cost the Exchequer £8.5 billion in unpaid taxes during 2018-19, and the government hopes the improved accuracy of new digital tax 26 July 2021

purchase price of goods and services you buy • Your total daily gross takings, if you use a retail scheme • Items you can reclaim VAT on if you use the Flat Rate Scheme.

You also need to keep digital copies of documents that cover multiple transactions made on behalf of your business by: • Volunteers for charity fundraising • A third-party business • Employees for expenses in petty cash.

If you’re a sole trader or already self-assess your income tax, you must keep digital records of all your business income and expenses, to be submitted through MTD-compatible software every three months.

All your transactions must be added to your digital records.

Invoices must be kept for a minimum of six years, but these can still be stored in paper format if preferred.

At the end of each financial year, you will also be able to submit any personal income and reliefs before you make a final declaration. This includes bank and building society interest, student loan repayments, dividends, and pension contributions. This system will replace the current self-assessment tax return.

Any tax owed will then need to be paid by 31 January the following year.

What software do I need?

Many people already use software to keep their business records, but you should check whether the software you use is MTDcompatible. If it is not, or if you currently rely on paper records, you should upgrade your systems and processes.

MTD-compatible software integrates with HMRC systems to send your financial data directly using an Application Programming Interface (API).

Making Tax Digital: a timeline 1 April 2019: MTD initiative was introduced for all VAT-registered businesses with a taxable turnover above £85,000 (the VAT threshold). A six-month exception was made for ‘more complex’ businesses such as trusts and not-for-profit organisations October 2019 More complex VATregistered businesses are required to comply with MTD April 2022 MTD will apply to all VAT-registered businesses, regardless of taxable turnover April 2023 MTD will apply to all self-assessment income taxpayers, unincorporated businesses, and landlords with a total income above £10,000 a year.

Record-keeping software enables you to enter and store your financial data digitally all in one place, then links to HMRC to be filed directly. If your existing software is not compatible, such as a spreadsheet or in-house book-keeping system, you may be able to continue using it by linking it to additional bridging software.

Bridging software can take information from other software, then convert it into a format that can be submitted digitally to HMRC, effectively acting as a bridge between you and HMRC. It must be able to extract or receive the information digitally – the key is that information must not be re-typed manually anywhere, to reduce the risk of data entry errors. Instead, it must only be exchanged digitally by, for example, linking cells in spreadsheets, emailing records to your accountant, or downloading and uploading files.

all your financial information digitally and ask your accountant to send it to HMRC, or you can send copies of all your physical paperwork to your accountant, who can then prepare your digital books and submit them to HMRC. This this will require more book-keeping work by your accountant, and will likely incur higher costs.

Ben Dyer, CEO of Powered Now, which provides field service management software for the trades, says: “Many businesses need to start giving some thought to MTD, but may not have done so. As a result, they are probably in for a bumpy ride. Every trade business should be considering their plans for MTD. My strongest advice would be simply this: don’t get caught out at the last minute, and plan early so that your finances are in check throughout the year.”

How much will it cost?

Any sole trader or small business that currently relies on paper accounts or simple book-keeping programmes is likely to face increased costs.

The government has said implementing MTD-compatible software could cost businesses around £175 upfront, with HMRC estimating that they will then incur continuing costs of about £20 a year, although the amount will vary from business to business.

However, the Institute of Chartered Accountants in England and Wales (ICAEW) has estimated that potential costs could be much higher, nearer £1,250. A poll by the Association of Taxation Technicians (ATT) showed that 45 per cent of businesses that have already signed up to MTD have paid anywhere from £109 and £500 to switch to the new system, while 12 per cent said it has cost them more than £5,000.

Although the core aim of MTD is to make the tax returns process easier and more efficient, almost 90 per cent of respondents to that survey said the new process had not reduced the number of errors, while many reported an increase.

What about Corporation Tax? We don’t yet know when MTD will be introduced for Corporation Tax payers. A formal consultation was held on the future design of MTD for corporation tax at the beginning of 2021, and the government is now considering the next steps.

It is expected that a pilot of the MTD initiative for Corporation Tax will take place in due course, but HMRC has said it will not become mandatory for Corporation Tax before 2026. ■ More information at: www.gov.uk/government/ publications/making-taxdigital

Can I sign up early?

A pilot scheme is already up and running for self-employed people who want to begin working to the new rules early. You can sign up at www.gov.uk/guidance/ sign-up-your-business-formaking-tax-digital-forincome-tax HMRC says around 30 per cent of self-employed people and landlords are already taking part in the pilot scheme, and is encouraging people to try it to get used to the process before the initiative becomes compulsory.

Can I use an accountant?

Yes. If you don’t want to submit your own returns, you can employ an accountant to do it for you, but your sales figures, invoices and expenses must still all be recorded digitally – you can’t just add up your figures and submit the totals.

REGISTERED GAS ENGINEER | OPINION

‘We need a single unifying voice’ A

single body or council should represent all buildings, products and services sectors to create a pragmatic and non-partisan pathway to achieve and promote the goal of net-zero carbon emissions, says Rinnai.

The company is also calling for that body to be composed of all interested parties – residential and industrial consumers, contractors, installers, distributors, designers, consultants and manufacturers – to plan for a realistic and practical route to net zero.

Rinnai managing director Tony Gittings says: “We need to look at this from the consumers’ viewpoint. We need to be putting accurate information in the public arena. There are a lot of interested bodies and companies showing understandable self-interest in wanting to know they have a future in the marketplace. We cannot be agnostic towards energy vectors of the future: the combination of hydrogen,

bioLPG and electricity combined will provide a robust decarbonisation pathway.

“In our sector, we have manufacturers of similar or like-for-like products who are looking to what will replace natural gas as the fuel of mass consumption and how that will affect them. We also have the pragmatic logic of trying to find affordable fuels for the mass market.

“Alternatives on their own are simply not an answer: we also need to look at the range of innovations and developments such as hydrogen and bioLPG that will come on stream.

“No single product or system is the panacea to the issue of carbon emissions: individual products have a place. But what would be the net-zero answer, as an example, to a commercial or industrial building envelope that has the added complications of needing Legionella prevention

regimes and constant hightemperature hot water in large volumes?

“How would electrification and heat pumps, for example, be attractive in terms of capital, installation and ongoing operational costs and performance? When we look towards notional building models within the new Future Homes Standard or the Scottish Energy in Buildings draft, these documents are clearly looking for a silver bullet

solution that doesn’t exist.

“Everything has a role to play and everything non-carbon can have a future. And a collective, equable effort will give us the result we all want – the result we must have if we are to have a sustained quality of life.

“Widespread unity and clear, responsible information exchange are required to avoid the partisan or the ‘silver bullet’ approach, avoiding technology dystopia in the future.”

Hydrogen: hype or gripe?

W

e know there is no silver bullet to decarbonising heat in the UK, says Vaillant Technology and Training director Mark Wilkins. Ultimately, we need clarity from the government so that heating manufacturers, gas and network providers have a clear strategy to determine the journey to decarbonising heat.

The past 16 months have been a huge challenge, especially for the government. The pandemic has pushed back the publication of numerous strategies such as the Future Homes Standard, the Heat and Buildings Strategy and the UK Hydrogen Strategy. As soon as these strategies are released, the industry can move forward in developing innovative new technologies and training programmes to support green jobs, ensuring we are prepared to reach the UK’s net-zero target and support a green economic recovery.

28 July 2021

While we are supportive of the long-term goal of green hydrogen, blue hydrogen has an important role to play as a stepping stone in the reduction of carbon emissions in the immediate future. It is true that blue hydrogen is produced from natural gas, but the CO2 produced is not released into the atmosphere. Up to 90 per cent of the CO2 can be stored in tanks or underground caverns, preventing emissions. Creating blue hydrogen can achieve lifecycle carbon emission savings of up to 85 per cent when compared with natural gas boilers being used today*.

Vaillant is a strong advocate of both heat pumps and hydrogen boilers, but arguably hydrogen is easier to store than electricity. In the peak heating season, energy demand is approximately four times the average demand for the rest of the year. Historically, this has been met via the storage of

gas for use at these peak times.

But a move to pure electrification of heat will pose significant challenges for the electricity grid to cope with seasonal demand. With little means of storage and the variability of wind and solar energy generation, there are challenges for green electricity generation.

Hydrogen, as a replacement gas, can be stored, overcoming the challenge of variability in electricity demand and generation throughout the year. Of course, other options such as hybrid heat pumps can provide an on-site flexible solution to cope with the seasonality of demand and provide a cost-effective, lowercarbon solution for those more hard-to-treat homes.

Heat pumps are a good alternative when homes are off the gas grid or for many retrofit properties that have a suitable

level of insulation. However, some existing UK homes need insulation upgrades before the installation of a heat pump is an effective measure. With the cost of a heat pump installation significantly more expensive than a boiler installation, and with a lack of incentives currently available, many homeowners will opt for a less costly approach.

Currently, many homeowners are unaware of the changes required to their heating systems, including how a heat pump works, how the system operates at lower temperatures, and the behaviours in the operation of the system compared with a traditional boiler.

We urge the government to act quickly and provide much needed clarity so that we can move forward in the decarbonisation journey. *Source: The CCC

Where next for heat networks?

Support is needed to encourage the growth of heat networks, says Peter Mills, Commercial Technical Operations Manager for Bosch Commercial & Industrial.

H

eat networks have been identified as a route to decarbonise heat at scale for some time. They have a unique ability to take all forms of heat generation, as well as waste heat, and have provided affordable heat across many European countries.

In the UK though, the industry still has some way to go in providing consistent results for users. In the best examples from Europe, consumers have very little need to even think about their heating and hot water, as it is just a reliable, stable cost in which there’s no need to worry about a boiler replacement cost coming out of the blue.

To get to this position in the UK, the heat network industry will need good regulation and standards that act as a foundation for consistency.

A recent consultation, Heat

Networks: Building a Market Framework Regulation, was disappointingly not mentioned in the Queen’s Speech, which most likely means it will not come into being until around 2025.

However, Ofgem has been announced as the regulator, which means that heat network customers will be on a similar footing to those using electricity or gas for their energy.

The industry will have to attract skilled workers at all levels to realise the significant uplift in the number of connections that will be needed to hit the government’s target of 18 per cent of UK heat coming from heat networks by 2050.

But it takes time to train people from scratch to work on complex heating systems.

Studies so far have assumed that skilled workers from the

gas industry would naturally migrate across, but will that happen? The same question applies to the heat pump sector, which has its own demanding targets and skills shortages.

and maintaining the number of egistered gas engineers over the past decade or so, and there are some lessons here for the heat network industry to learn.

Good, well-trained workers

“Studies so far have assumed that skilled workers from the gas industry would migrate to work on heat networks – but will that happen?”

Gas engineers are still much in demand, maintaining and replacing existing gas appliances.

We also know that a significant number are heading towards retirement, and others are reluctant to add significant new skills.

The gas industry has broadly done a good job of building

enjoy a recognised status, which, in turn, leads to a professional pride in the work they do and consistent outcomes.

This is where specific recognised qualifications come in and I think this is something the heat network industry really needs now to start propelling itself forwards. ■

Legislative, Normative & Informative The Gas Safe Register Legislation & Standards Document List Date issued: 1 July 2021 Introduction This document defines all documents recognised by Gas Safe Register as being Legislative, Normative (gas standards) and Informative reference documents.

Some documents may only be available as hard copy documents, but the majority are available to download, either via Gas Safe Register’s engineer website or from the organisation or body promoting the document. In some cases, the document is only available for purchase from the organisation or a recognised supplier.

Hierarchy of legislation and standards In this document list, the hierarchy of documents within the following tables is defined in order of significance.

Detailed first are Statutory Acts, or regulations that are legally enforceable. These are followed by a recognised list of documents known as ‘Second Tier’ documents. This series of documents provides practical guidance on ways to comply with the functional requirements of regulations. This guidance is not law, but provides information that, if followed correctly, will ensure that legal obligations have been met.

Where someone chooses to depart from this guidance, they will need to ensure that the method chosen provides equivalent or better standards of safety than the relevant published guidance.

The guidance provided within appropriate second-tier documents will be used to assess compliance.

The next tier of documents is gas industry standards that are aimed specifically at the installation, commissioning or maintenance of gas equipment (pipework, appliances, etc). These are known as Normative Documents and are referred to as ‘Gas Industry Standards’. These documents, in conjunction with any available manufacturer’s instructions, will be used by Gas Safe Register to assess compliance.

Finally, the remaining listings provide details of links to other available information, which is considered useful to help

32 July 2021

registered businesses comply with their obligations and assist them in carrying out their day-to-day activities. These are referred to as Informative Documents.

1. Hierarchy of documents Legislation In this section, the listed documents are those brought to the Statute Book by an Act of Parliament and are referenced as Statutory Instruments (SI) or equivalent. These are the law in the respective countries as stated and must be followed. The SI Reference number (or equivalent) is preceded by the year of it being added to the Statute Book, ie, the Gas Safety (Installation and Use) Regulations 1998 has an SI Number of 1998:2451.

Regulations are in general written in a format that provides high-level requirements.

Documents supporting legislation These documents provide practical guidance on ways to comply with the functional requirements of the regulations. For the Building Regulations, these are outlined in a series of Approved Documents (AD) published by the appropriate government department responsible for the regulations.

The ADs that currently apply to gas work are: • A Structure • B Fire safety • F Ventilation • G3 Hot water storage • J Heat producing appliances • L Conservation of fuel and power • M Access to and use of buildings • P Electrical safety in dwellings.

Each document contains general guidance on the performance expected of materials and building work in order to comply with each of the requirements of the Building Regulations; and practical examples and solutions on how to achieve compliance for some of the more common building situations.

2. Gas Industry Standards In this section are all the Gas

Industry Standards published by the three current Standard Setting Bodies, which are: • British and European Standards (BSI) • Institution of Gas Engineers and Managers (IGEM) • Liquid Gas UK (formerly known as UKLPG) One standard is published by National Caravan Council (NCC).

3. Documents under review If it is known that the three-month validity period coincides with a period of time in which a standard being revised is out for public comment, the final date for comment will be included.

Gas Safe Register will use best endeavours to keep the documents under review as up to date as possible, but the Register is NOT responsible for reviewing, revising or updating industry standards. Where a registered business or industry stakeholder has an enquiry about revisions to guidance documents, this should be directed to the relevant Standard Setting Body.

Comments on draft standards can be submitted to: • British and European Standards (BSI) https:// standardsdevelopment. bsigroup.com (registration required) • Institution of Gas Engineers and Managers (IGEM) www.igem. org.uk/technical-services/ comment-on-draft-standards/

4. Links to online documents When viewing this document online, hyperlinks are active, so that you can open the document and read it or save it for later use.

However, all saved documents will be considered as uncontrolled versions and you should check that you are referencing the current version.

5. 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.

However, it is recognised that, due to the differences of individual legislation used in different geographical areas, there will be some differences in application.

While conducting inspections, due regard will be taken of the requirements of all appropriate guidance.

6. General This Gas Safe Register document will be updated and republished on, or about, the following dates each year: • 1 January • 1 April • 1 July • 1 October.

If you identify an error in this document, or you are aware of reference documents that may be useful that you think should be added to future editions, please email: technical@ gassaferegister.co.uk BSI, IGEM and Liquid Gas UK develop and publish guidance with the help of industry in the form of committees. Gas Safe Register does not have any responsibility for the development and publication of this type of guidance document.

Why do you need a thermal imaging camera?

A thermal imaging camera is a useful addition to the gas engineer’s toolbox, saving time when diagnosing faults and problems, as well as increasing earnings potential, writes Kane marketing executive Scott Holliday.

T

hermal imaging cameras convert thermal energy (heat) into visible light that can be seen on screen. Most objects emit heat that makes them visible to thermal devices, even when it’s dark, and this includes mechanical equipment. Thermal imaging cameras are precise and they only require a small amount of heat to work – which makes them useful for fault-finding.

They use infrared thermal radiation to capture and evaluate heat being absorbed, transmitted or reflected. The hotter the object, the more radiation it will emit.

A thermal imaging camera can differentiate between heat sources and minuscule differences in thermal radiation, translating the

information into a heat map that shows the different heat levels.

Using thermal imaging means the days of guesswork are gone: the simple point-and-shoot technology helps you to find heating system and plumbing faults quickly and efficiently.

Leaks It can detect problems that the human eye can’t: for example, if your customer has a leak coming through the ceiling or under the floor, in the past you might have had to excavate the area to find the source, running the risk of getting it wrong.

It can also pinpoint underfloor heating circuits. The camera enables you to see the gap in the

pipework pattern that suggests there could be a blockage or leak; or see a potential flaw in the surrounding insulation where the pipework is heating the earth rather than the room itself.

They really come into their own in being able to see a blocked pipe or radiator, and you can show your customer a clear image of a blockage or inefficient radiator that highlights the need for a powerflush.

They can also be used to confirm heating system cold spots, showing which parts don’t work correctly, and to highlight the inefficiencies of old heating systems, showing variable heat distribution in each room.

A thermal imaging camera

should be seen as a great investment. It will not only save you time but could help you earn more money. ■ www.kane.co.uk/launch-kanetcam

Productnews Spirotech adds whisper-quiet commercial vacuum degasser

Worcester Bosch Greenstar 4000 range upgrades Greenstar i

Spirotech has added to its range of powerful vacuum degassers with the SpiroVent Superior S250 for smaller commercial closed heating and cooling systems.

The S250 is suitable for locations such as schools, restaurants and bigger homes and is designed to operate almost silently. It has been created in response to increased demand for low-temperature systems, such as in underfloor heating, where it is difficult to detect where air can be released.

Air in the system leads to corrosion and a destructive

Worcester Bosch’s new Greenstar 4000 boiler range replaces the Greenstar i series, building on the tried and tested features of its predecessor while upgrading its appearance and performance.

Key improvements include increased ease and speed of installation, commissioning and servicing, alongside better efficiency and control for the user. The new range includes features from the premium 8000 Style and provides greater siting flexibility.

The Greenstar 4000 has been designed with a boiler switch in mind, to ensure that current Greenstar i owners can replace their i Junior, Si or i system boiler with a 4000, thanks to the same fixing points, pipe centres and flue to valve distance. This means the 4000 can be installed with minimum time and effort, says the company.

The wall-frame also provides a pre-piping option for all connections before the boiler is hung.

The Greenstar 4000 adopts the modern, sleek look and feel and practical design from the Greenstar 8000 Lifestyle range. The front and right-hand side panels are removable for easier access for maintenance and servicing.

All polystyrene packaging has been replaced with recyclable honeycomb cardboard, and all plastic bags have been replaced with compostable bags.

Martyn Bridges, director of Technical Communication and Product Management, says: “The Greenstar 4000 series builds upon everything people love about the Greenstar I, with improvements to make it more accessible and attractive to installers and homeowners alike.

“From simplified servicing and high-tech control systems to quieter operation and increased efficiency, we hope that installers fall in love with this boiler just as much as the Greenstar i that it replaces.” www.worcester-bosch.co.uk/4000

sludge, also creating noise from components such as pumps, which can cease to work efficiently.

Business director Rob Jacques adds: “Unlike with higher temperature systems, where you can predict where air will appear and then expel it with deaerators, in low-temperature systems it’s often impossible to determine where that would be.

“With a vacuum degasser, this is no longer an issue, improving efficiency and extending years of service.”

The S250 processes up to 74 litres of liquid per hour and operates at 41 decibels.

Rob aadds: “With locations such as restaurants, hotels and people’s homes, it is important the unit operates as silently and smoothly as possible. For the S250, this is barely a whisper.

“This is achieved by the unit’s patented Venturi loop, a speedcontrolled centrifugal pump with a Venturi tube that creates low pressure in the vacuum tank to degass the system water.” www.spirotech.co.uk/s250

Compatible with Legrand’s smart radiator valves, the Smarther with Netatmo thermostat can be flush or wall mounted: flush mounting the wired system, using a versatile backbox, allows the thermostat to protrude just 12.6mm from the wall.

The Home + Control app is compatible with Google Assistant, Apple HomeKit and Alexa so that users have voice control of their heating. They can set weekly schedules based on daily routines, and a new boost setting can turn the boiler on for 30, 60 or 90 minutes for immediate comfort.

The smart thermostat is programmed to understand both how the home heats and the efficiency of the boiler. In essence, this means that it gathers an understanding of how long the boiler take to reach optimum temperatures and, therefore, knows when to switch on to achieve the required levels of heating.

Richard Hopkins, lead marketing manager at Legrand UK & Ireland, says: “Smarther with Netatmo has been designed to offer the very best smart thermostat system. Replacing traditional thermostats, its compatibility with other smart home devices, such as smart radiator valves, means that end users can benefit from a number of energy saving settings.” www.legrand.co.uk/products/ user-interface/netatmo-pro/

Stelrad enhances coloured rad range from stock Stelrad has added to its range of coloured radiators held in stock that can be delivered within 24 hours.

The new Silhouette Concept will be available in anthracite grey in both the Vita and Softline Series.

“The addition of coloured options from stock has been well received,” says head of marketing Chris Harvey. “We have decided to meet the demand from customers by adding to the range available in both the Vita and Softline Series.

“It’s clear that radiators are being seen by many as part of the décor in a home rather than simply as a heating appliance. We are seeing far higher sales of the decorative and designer radiators

we manufacture here in the UK and, alongside this, we’re seeing the trend for coloured radiators very much on the rise. We anticipate seeing significant increases in sales of coloured radiators in the months ahead.” www.stelrad.com
