The impact of COVID-19 has hit all areas of industry in a variety of different ways; with mass redundancies, restructures and the need for diversification now dominating the headlines. It has also made a lot of people question their own careers and what is important to them; in fact, Google searches for the term ‘career change’ are up more than 500% on this time last year. With more than half of the heating and plumbing industry’s workforce due to retire in the next decade, and so many people considering a career change (either through choice or necessity), is there a window of opportunity for the heating engineering and plumbing industry to attract men and women to the industry? Why is there a need for recruitment in the industry? In 2017, the Gas Safe Register’s ‘Decade in Review’ found that the average age of heating installers was 55, with over half of respondents being this age or older. The report also found that over 50 per cent of engineers are concerned about keeping up with advancing and unfamiliar technology. Over the next decade, this aging With more than half of the heating and plumbing industry’s workforce due to retire in the next decade, and so many people considering a career changeworkforce will begin to reduce their working hours or retire completely. With fewer young people deciding to train as a heating installer, the industry will quickly lose valuable experience as the workforce diminishes. In addition, a survey by the Centre for Ageing Better found that, of 500 employers, only 20% have considered how they will tackle an aging workforce, and 24% have no strategies in place. How can heating installers promote their career path? As of October 2020, the UK unemployment rate has risen to its highest level (4.5%) in over three years. According to the ONS, an estimated 1.5 million people were unemployed between June and August, while redundancies stood at 227,000. Of those now facing unemployment, about 300,000 are aged 16-24. With so many young people out of work, and plenty of adults looking to make the move from an office-based role to one that’s ‘more rewarding’, a career in the trade could be an attractive option. But, how can heating installers market themselves as a prosperous career path to these people? Be positive on social media Social media platforms like Twitter, Facebook, Instagram, and LinkedIn have provided installers with a way to market themselves to customers, share their successes, and connect with others in the industry. This is all great, but often heating installers use social media to vent their frustrations, complain about long hours and feeling tired, or even complaining about customer behaviour. While this is absolutely understandable (we all need to let off steam from time to time), this kind of content should be shared on private accounts only seen by family and friends. It may be worth setting up a second account which can be seen by the public and only share positive content there. This will show followers (who are potential recruits and customers) the more positive aspects of the career. Talk about benefits and progression opportunities When attracting young people to any profession, you need to emphasize the opportunities it offers in terms of progression, potential earnings, and other benefits such as being self-employed and therefore being able to manage your own hours and holidays. Offer an apprenticeship scheme By offering a paid apprenticeship scheme you can attract both young people and older career changers who have financial responsibilities to meet. You know better than any that it takes time to train as a heating installer, as well as a lot of on the job experience, and a paid apprenticeship could make the career a viable option for people with financial commitments. Make it clear to new recruits that they will be supported and mentored throughout their training. Will the Green Homes Grants scheme help the heating industry? Finally, it is important to address the government’s Green Homes Grants scheme which began accepting applications in September and will be open until 31st March 2021. The scheme offers £5,000 vouchers to homeowners in England to cover two-thirds of the cost of energy-saving improvements such as improving insulation and installing renewable heating systems like heat pumps, biomass boilers, and solar thermal panels. In addition to encouraging homeowners to reduce their carbon emissions in line with the government’s target of reaching net-zero emissions by 2050, the scheme Google searches for the term ‘career change’ are up more than 500% on this time last yearis also intended to boost employment. The increased interest and investment in the renewable energy sector could indeed open up more opportunities for the unemployed, but as the scheme is only open until March 2021, this does not seem to be a particularly long-term approach. Homeowners cannot use the grant to install a more efficient gas or oil boiler, so it is unlikely to help the heating industry to attract recruits who will become traditional boiler installers, but it may kickstart the renewable heating industry and encourage existing heating professionals to diversify their skillset. Of course, there is always the possibility that increased awareness of the need to reduce carbon emissions and make our homes more efficient will have a knock-on effect for the boiler installation industry, but only time will tell. Use digital advertising When people are looking for a job, or even when they are just passing the time at home during lockdown, they will usually be online. When you have a job opening or an apprenticeship on offer, be sure to advertize on digital platforms including job posting websites, LinkedIn, search engine and social media advertising. Be open to diversity If the industry is only open to attracting men of a certain age from a certain background, the number of potential recruits reduces rapidly. The heating industry is one of the least diverse, particularly in terms of gender as only 0.4 per cent of Gas Safe registered engineers are female. Heating installers and employers not only need to be willing to hire a more diverse workforce, but they also need to be proactive in their efforts to attract candidates to ensure everyone feels welcome and supported in the industry.

Pete Mills, Commercial Technical Operations Manager at Bosch Commercial & Industrial outlines how cities are using heat networks to achieve UK carbon emission targets. Heat networks, or district heating, are becoming an ever-greater part of our industry’s involvement in larger scale schemes. The ability to help the decarbonization of heat both now and in the future has made them an attractive solution to the new-build sector, as well as those undergoing deep renovation works. Net zero 2050 The UK’s net zero 2050 target may seem like a long way off. But steps need to be made now in order to reach this, something that our leading cities have recognized. Many have set their own carbon targets to ensure they stay on track. This is why heat networks’ ability to provide efficient heat and hot water to multiple buildings (and as the name suggests, whole districts) is a particular reason why many cities up and down the country are turning to them as a solution. What are heat networks? Generally, heat networks are defined as a system of supply pipes with a centralized heat generator (Energy Centre) that serves multiple domestic or non-domestic dwellings. These are usually in different buildings, but sometimes within a single large building like an apartment block or a university campus.District heating is often used to describe larger scale systems District heating is often used to describe larger scale systems of this sort, where there will be many buildings connected over a larger geographic area. In these systems, although the heat is provided ‘off-dwelling’, it is also common to have more than one energy centre. The principle is that energy for heating (and sometimes cooling) is supplied through the system of pipes, with each individual user being metered for the energy they use. Minimize pipe lengths Heat networks offer a number of advantages but are best suited to areas where there is high heat density, that is to say where there are multiple ‘households’ close together in order to minimize the length of pipes within the network. One of the key advantages for heat networks is their adaptability to use any form of heat generation. A key advantage from an environmental perspective is that they make use of waste heat, from sources such as electricity generation, waste incineration and industry. Heat networks are defined as a system of supply pipes with a centralized heat generator that serves multiple domestic or non-domestic dwellings The scale of the combined heat requirements of all these dwellings also helps the inclusion of renewable energy sources, which may be more difficult and costly to achieve at the individual dwelling level. Overall, their flexibility to use whatever heat source is available, makes them easier to decarbonize in the future.Other key benefits for Local Authorities and Housing Associations have been the elimination of individual gas appliances within dwellings. This has significant cost savings reductions for Local Authorities and Housing Associations where gas landlord checks are eliminated, along with the issues associated with access. City developments Today City Councils and developers are opting for heat networks to provide the heating and hot water for new redevelopment projects. The largest of these is the ambitious Leeds Heat Network, which once completed is set to be one of the UK’s largest new heat networks, connecting 1,983 council homes and numerous businesses in Leeds. The first scheme under the City Region’s District Heating program, the green initiative looks to reduce carbon emissions for the area as well as energy bills for the residents living there.The green initiative looks to reduce carbon emissions for the area Even more innovative is how the network will connect to the Leeds Recycling and Energy Recovery Facility, which burns black bin bag waste to generate heat. In theory this would make the network fully sustainable. There will be back-up support from efficient Bosch Commercial & Industrial boilers, which will only be switched on when required, say the colder months where the need for heat is higher. Climate change targets An hour’s drive away from Leeds is the city with one of the most ambitious climate targets in the UK. Manchester intends to be carbon-neutral, climate resilient and zero waste by 2038 – 12 years before the overall UK net zero 2050 target needs to be hit.To help achieve its ambitions, work has been taking place on the Manchester Civic Quarter Heat Network (CQHN). Manchester hasshown the versatility of heat networks due to the number of commercial buildings it will support The project will generate low-carbon power, heat and hot water for initially six council buildings and some residential properties with the possibility for the network to grow and connect further buildings across the city centre. Some see district heating as a solution solely for residential purposes, however Manchester have shown the versatility of heat networks due to the number of commercial buildings it will support. The project itself has also given Manchester a new landmark, the impressive ‘Tower of Light’, which incorporates the five flues from the technology powering the network. This beacon not only represents the city’s commitment to reducing its carbon footprint but also the innovative nature of district heating. Heating Battersea Power Station The final example lies in the Capital and may be one of the most famous developments in the UK at the moment. Battersea Power Station is not only one of the most iconic landmarks in London, but also the center piece of one of the most high-profile, large scale mixed-use redevelopment projects ever undertaken in the Capital.Battersea Power Station is a high-profile, large scale mixed-use redevelopment project The project involves the development of a district heating and cooling network, with a two-level underground energy centre – one of the largest of its kind. This complex heat, cooling and electricity network will continue to expand as the project continues to undergo its development stages. Looking ahead These are just a few examples of cities taking advantage of district heating and its many benefits, but near all cities in the UK have multiple heat network projects underway. Like with most innovations, smaller urban areas should then follow suit. The importance of district heating will no doubt become more and more prominent. Its ability to power whole areas and multiple buildings can already help efficiency levels, however its potential may be even greater in the future. One key energy transformation that is looking more and more likely is the decarbonization of the gas grid to hydrogen blends and ultimately 100% hydrogen. If these can be utilized in heat networks then the benefits will definitely put us and UK cities in a good place as we continue our journey towards net zero.

As the UK continues to battle through the coronavirus crisis, HVAC business owners and installers can be putting some of their enforced downtime to good use. This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up. One way of doing this is by sharpening the focus on markets which promise strong growth – and few markets are growing faster than that for heat pumps.   The potential here is huge. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30%. That equates to sales doubling every three to five years. New-builds account for the majority of those sales, but 30% are retrofits, and about 30% of those retrofits are in private residences. This means there’s a big opportunity for doing conversions from oil boilers to heat pumps at rural homes not connected to the gas grid. The ‘New Normal’ and Heat Pumps It is only realistic, of course, to expect a lingering dip in HVAC sales of all kinds, including heat pumps, until the post-pandemic world gets back on its feet. But when we do turn the corner into the ‘new normal’, heat pump sales will again climb strongly. One reason for this is consumer demand, the other is government policy. End-users are now increasingly aware of the dangers and disruptions threatened by carbon emissions and climate change – informally known as ‘the Blue Planet Effect’ – and more are being guided by their consciences to make environmentally-responsible heating choices. An Expected Spike In Demand Many end-users are also encouraged by the prospect of receiving payments from the government through the Domestic RHI tariff. When we do turn the corner into the ‘new normal’, heat pump sales will climb strongly If RHI tariffs are the carrot, however, the government is also going to wield a big stick. The Chancellor’s spring statement last year dropped the bombshell that low-carbon heating systems, not fossil-fuel heating, should be installed in all new homes built after 2025. Though this policy might perhaps get slightly delayed and diluted, there can be no doubting that radical change is on the way.           With all this in the pipeline, the industry should be preparing now to cope with the increased demand. But there’s some way to go: of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps. Many more will be needed. MCS Certification Some installers are already recognizing this opportunity. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30% This is evident in the heightened level of interest in the one-day introductory heat pump courses run nationwide by the Viessmann Academy. These courses provide a useful overview of what heat pump installations involve, helping participants decide whether or not they would like to go on to qualify with the MCS quality assurance scheme. This is a crucial decision, because having MCS certification is an obligation when installing equipment eligible for Domestic RHI payments. Some course participants decide to take the next step to MCS certification straight away, others decide to wait a while – but standing still in a fast-moving market can mean getting left behind! F-Gas Certification So what else must HVAC businesses and installers consider about heat pumps, in order to stay ahead of the game? In addition to MCS certification, F-Gas certification is also necessary when split air source heat pumps are installed. This is because the outdoor and indoor units have to be connected on-site with refrigerant pipework. Some installers choose to get F-Gas certified themselves, others sub-contract this part of the job to someone who’s suitably qualified. Of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps It is possible to sidestep this need, however, when it is appropriate to install a monobloc heat pump – and the widening choice and affordability of monobloc designs is making them appropriate for a wider range of properties. A good example of this is Viessmann’s new Vitocal 100-A, an outdoors unit which has no need for a complementary indoor unit and is also easy to install because most components are integrated in the unit. New, compact and affordable air source heat pumps such as this, offering much-needed space-saving solutions for urban homes, are another reason why the heat pump market will boom. The Challenges Of Heat Pump Installation Though technological advances are making things easier, installing a heat pump isn’t ever going to be quite as straightforward as replacing an old boiler with a new one. Before starting an installation, first it is necessary to assess whether a heat pump is suitable for the property. This means checking that the property is well-enough insulated; checking the existing system’s radiators, which may need supplementing or replacing with bigger radiators or underfloor heating because of the lower flow temperatures of a heat pump system; and calculating the required size of the heat pump according to the building’s heat loss (and not including hot water demand). This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up At the installation stage itself, much of the work will be familiar to boiler installers, though weather compensating controls are obligatory for all MCS-approved work and as part of building regulations Part L. It’s also important to note that planning permission requires minimum distances between the heat pump’s outdoor unit, the plot’s borders, and neighboring properties. If this seems complicated, it doesn’t have to be: some heat pump manufacturers provide a calculator to simplify the task. Now Is The Time To Be Proactive Just as installers need a little time to assess whether a property should switch from a boiler to a heat pump, end-users also need a little thinking time, to consider adopting a technology new to them. By being proactive, HVAC businesses and installers can reap what they sow When customers get in touch because their existing boiler has broken down, the pressure for a quick fix can rule this out. But right now, when many of us have time on our hands, there’s the chance to inform customers of alternative heating solutions before their boiler needs replacing. Taking such pre-emptive action, by emailing information or mailing leaflets to customers, does require a little effort, but at least now there’s the time to do it. We are heading into a new era which will see boiler sales decline while heat pump sales rise. By making preparations for these profound changes, and by being proactive, HVAC businesses and installers can reap what they sow.
