The Low-Carbon Heating Toolbox: Making The Case Beyond Heat Pumps
The Low-Carbon Heating Toolbox: Making The Case Beyond Heat Pumps

At the moment, it seems as though a day rarely goes by without low-carbon heating hitting the headlines. Whether it is reports of ‘revamping’ the Clean Heat Grant, to include a ‘boiler scrappage’ scheme, which may offer home owners up to £7000 to make the switch to a low-carbon alternative, to speculation that the Prime Minister is under pressure to push back the 2035 ban on gas boilers, the debate on how and when the low-carbon heating revolution will happen is ongoing. BEIS Hydrogen Strategy We have also seen the recently published, Hydrogen Strategy from the Department for Business, Energy and Industrial Strategy (BEIS) that cements its plans to develop technologies that allow hydrogen-powered heating in people’s homes. In addition to this, the Future Homes Task Force, including some of the United Kingdom’s largest property developers, regulators, suppliers and environmental groups, have agreed to the sector-wide Future Homes Delivery Plan, to build homes that are ‘zero-carbon ready’ and sustainable by 2025. Alternative energy, key to hitting net zero targets by 2050 What is also clear is that tackling the decarbonization of heat is not a one-technology solution According to the Climate Change Committee, in a report published in December 2020, the UK’s homes are responsible for around 15 percent of emissions. As a result, the need to install alternatives to traditional fossil fuel heating systems will be crucial, to hitting our net zero targets, by 2050. This will be the key challenge that the delayed Heat and Buildings Strategy, now due in the autumn season, will need to address. Therefore, what is also clear is that tackling the decarbonization of heat is not a one-technology solution. Target to install air source heat pumps in UK homes So far, much of the focus has been on heat pumps, as the UK Government has set an ambitious target of installing 600,000 air source heat pumps (ASHPs) in UK homes each year, by 2028. However, there are a number of challenges to achieve this goal, as house builders will need convincing to install heat pumps in new builds, and home owners and landlords will need convincing to retrofit older properties. Cost, a key issue in air source heat pumps installation Cost will also be a key issue, even with a government grant and ASHPs can be complex to install. They can also emit noise that breaches legal limits, if placed too close to a neighboring property. In addition, they won’t be suitable for all properties, as the needs of a 4-bedroom new build home are very different to a 1970s apartment, a Victorian-era terrace, a social housing property or an off-grid home. Computer-controlled infrared heating (CCIR) One of the alternatives is computer-controlled infrared heating, which addresses many of the issues faced by ASHPs Taking all of these challenges into account, BEIS has said that it is ‘uncertain’ what the ‘optimal solution’ is, when it comes to low-carbon heating. Certainly, there is not a ‘one-size-fits-all’ solution for heating the UK’s homes, which is why it is vital that house builders, landlords, contractors, installers and developers explore the full range of low-carbon heating technologies that are available today. There are alternatives that can provide benefits that are much more likely to appeal to a wider range of end-user audiences. One of the alternatives is computer-controlled infrared heating (CCIR), which addresses many of the issues faced by ASHPs. High-performance heating Firstly, infrared is an intrinsically more effective source of heat than conventional convection heating, because it heats the material within a room, rather than the air, which can escape from doors and windows. CCIR systems also outperform many other low-carbon technologies, because the software within each panel constantly monitors each individual room and learns about the energy storage characteristics within it, adjusting its routine to maintain the ambient temperature within the room, maximizing its performance and using fewer units of energy, in comparison to a traditional heating system. KERS water heating system This keeps energy bills low, and meets increasing sustainability standards. Figures show that, out of 29 million homes in the United Kingdom, 19 million have an EPC lower than C. Together with Ambion Heating’s KERS water heating system, inefficient properties can be brought up to a minimum EPC C. CCIR also costs less to install than many other low-carbon heating alternatives CCIR also costs less to install than many other low-carbon heating alternatives. In a typical three-bedroom house, for example, the estimated cost of installing a CCIR system is around £6,000, compared to nearly £10,500 for an ASHP. They are also easy to install, whether they’re being retrofitted into an existing building or installed within a new build, because they can simply be wired into the mains, by a qualified electrician. Enhanced comfort and reduced emissions The heat CCIR provides feels more natural and comfortable, once the fabric of the room is saturated with energy, and it emits a comfortable, radiant heat. It also reduces humidity, as well as improves the air quality within a building, reducing the amount of circulating dust. In fact, in an independent performance review, CCIR provided the same levels of comfort within a room, using 60% less energy than a standard electric convection system, and on a par with ASHPs. Heating solutions for a low-carbon future While there is a real urgency, when it comes to decarbonizing heat, it’s vital to consider which technologies offer the most benefits to the end user. By understanding and investigating all of the alternatives to gas central heating, such as CCIR, the benefits will not only be felt in the short term, they are a sustainable solution for the longer term.

BEIS Hydrogen Strategy, Reaction From Baxi Heating
BEIS Hydrogen Strategy, Reaction From Baxi Heating

The energy transition is upon us and we are shifting today’s energy use to low and zero carbon sources. The way in which we heat and provide hot water to our homes and businesses will change, and we are developing technologies that will support this transition. A bold and pragmatic policy framework will encourage investment and drive change. BEIS Hydrogen Strategy We, therefore, welcome the publication of the Hydrogen Strategy from the Department for Business, Energy & Industrial Strategy (BEIS). This important document details the role and vision for clean hydrogen deployment at scale, in the United Kingdom, building upon the ambitions in last year’s 10 Point Plan for a Green Industrial Revolution. As an energy carrier, hydrogen has many uses that will help to decarbonize heating, transport and industry. We, therefore, welcome the government’s assurance to the public that hydrogen can be made as safe as natural gas. UK Government’s Contract for Difference The availability of low-cost hydrogen at scale is a key enabler of the deployment of hydrogen for heat Alongside the BEIS Strategy, the UK Government is publishing its proposed business model for supporting hydrogen production, in the form of a Contract for Difference. This approach has been utilized successfully for offshore wind and will enable the sector to invest in early-stage projects, and reduce the cost of hydrogen. The availability of low-cost hydrogen at scale is a key enabler of the deployment of hydrogen for heat. We believe, there is no ‘one size fits all’ solution, and a whole range of heating technologies will need to be deployed for a range of properties. Baxi Heating, as part of BDR Thermea Group, is at the forefront of developing clean heating solutions, including our ground-breaking development of hydrogen boilers. Hydrogen-ready boilers from 2025 Our work with the Hy4Heat project and associated demonstration sites in the UK show technical feasibility of this solution. We believe the government should act upon advice from the Climate Change Committee and other sources advocating a mandate that all boiler sales from 2025 should be hydrogen-ready, in order to help pre-populate a swathe of the housing stock, ready for a future conversion. Technology, energy efficiency and business models are all bit parts in the wider picture. Skilled installers and contractors will be utterly essential to success, so we are glad to see the announcement of a hydrogen sector development action plan in early 2022, setting out how the government will support companies to secure supply chain opportunities, skills and jobs in hydrogen. UK Heat and Buildings Strategy Following the Hydrogen Strategy, we look forward to several important publications in the lead up to the 26th UN Climate Change Conference of the Parties (COP26), including consultations on the role for hydrogen-ready appliances, off gas grid heating measures and the UK Heat and Buildings Strategy.

Renewable Heating Is The Future For Commercial Buildings
Renewable Heating Is The Future For Commercial Buildings

In 2019, the UK became the first major economy in the world to pass laws to end its contribution to global warming by 2050 - a landmark moment on the road to net zero. To meet that target, owners and managers of commercial buildings are increasingly facing more standards, regulations, and legislation to promote carbon reduction. This may pose challenges when it comes to investing in building service technologies, but the net-zero goal also provides an opportunity to embrace new approaches to the design and operation of commercial buildings. Heat commercial buildings When we look at reducing the carbon impact of a building, heating is an important factor to consider. Heating and hot water are significant contributors to a building’s carbon emissions. In fact, they create nearly a third (32%) of the total carbon emissions in the UK. Luckily, the technology to heat commercial buildings in a more energy-efficient, renewable way is already out there - in the form of heat pumps. There is legislation focused on the provision of heat to commercial buildings that need to be considered So, what benefits can heat pumps offer, and how can building managers be sure that they are the right solution for a commercial space? There are already regulations in place to help reach net-zero – from the Climate Change Act in 2008 to the Green Growth Strategy in 2017. More specifically, there is legislation focused on the provision of heat to commercial buildings that need to be considered. Energy efficiency standards Part L of the Building Regulations states that non-domestic buildings should be moving to low-carbon heat sources, the minimum energy efficiency standards means it’s illegal to let any property with an EPC rating of less than band ‘E’, and the Non-Domestic RHI has been extended until 2022, in order to help overcome barriers to investing in renewable heating. There is also growing interest in embodied carbon in commercial buildings, and considering the amount of carbon produced by a building across its whole lifecycle, it’s important to understand the full environmental cost of the extraction, processing, manufacture, delivery, and assembly of every single product or material used. Conventional electric heating The government has already set a target of 600,000 heat pump installations per year by 2030 Needing to consider all of these factors may seem like a lot, but it serves to show that focusing on renewable heating now is the best way to future-proof commercial buildings for years to come. Heat pumps are central to reaching this decarbonized future, with the Carbon Trust finding that heat pumps have the potential to deliver CO2 savings of up to 70% compared to conventional electric heating, and up to 65% compared to an A-rated gas boiler. The government has already set a target of 600,000 heat pump installations per year by 2030, and the Committee on Climate Change estimates that 19 million heat pumps will need to be installed by 2050 to achieve the net-zero goal. Offering renewable heating To reach this goal, uptake needs to maintain momentum. As well as offering renewable heating, heat pumps allow for a reduction in running costs and increased efficiencies, and are increasingly becoming the first choice for building managers planning renovations - because they are designed for both retro-fit and new build, are easy to design and install, and are scalable to work with other systems. In the years since heat pumps first became available, the choice of heat pumps has expanded This means they’re a suitable solution for almost any space, and are even able to work alongside existing heating systems in a hybrid situation if required. A heat pump is an ideal solution for commercial buildings, it’s just a case of finding the right one for the job. In the years since heat pumps first became available, the choice of heat pumps has expanded, and building owners are now able to select exactly the right equipment for a building’s requirements. Combining residential homes For example, heat pumps can now work at higher temperatures, meaning they are a great option for spaces like hotels, hospitals, and leisure centers where there is a high demand for hot water at peak times – removing the need to use a gas boiler. This is also a compelling case for heat pumps in mixed-use buildings – which is a burgeoning space in the UK-built environment. Buildings which combine residential homes and commercial businesses have a wide variety of heating and cooling requirements within the same structure. Traditionally, this is where gas boilers, combined heat and power systems, or electric water heating would have come in. Heat pump installations Modern heat pumps can also be applied in buildings alongside other technologies Now, high-temperature heat pumps – like the 40kW Ecodan QAHV – can deliver hot water up to 90°C, helping businesses increase the efficiency of hot water production while slashing their carbon footprint. Other heat pumps can offer options for a modular approach, so that multiple devices can operate in one system. This means that the multiple-unit system can cascade available units on and off, to meet the required load of a building. It also means heat pump installations are scalable, and can work for a small doctor's surgery through to entire district heating projects. Modern heat pumps can also be applied in buildings alongside other technologies, and boost the renewable element of a project – reducing the requirement for heat energy. Commercial heat pumps Finally, to satisfy these needs without compromising on sustainability and the green imperative would have been challenging, before the advent of commercial heat pumps. Reaching net-zero and moving to renewable technology is now a priority for everyone. For building services professionals, there is a real opportunity to lead the way, and encourage clients to take a new approach to heating and hot water in commercial buildings. The heating equipment we install will be in a building for at least a decade, so installing a heating system based on fossil fuels might risk leaving the building as a ‘stranded asset’ in the future. Making the move to renewable heating will help ensure buildings are meeting efficient and environmental standards for years to come.

Friedrich Air Conditioning Discusses The Benefits Of Installing Portable Air Conditioners For Hot Summers
Friedrich Air Conditioning Discusses The Benefits Of Installing Portable Air Conditioners For Hot Summers

Portable air conditioners have become a popular summertime cooling solution, valued for their easy, non-intrusive installation, fast set up, and the ability to easily store them away after the summer season ends. There is no end to the possible applications for a portable unit. Bedrooms, sunrooms, workout rooms, garages and other areas where relief is needed from the sweltering summer months are a great place to use a portable AC. Even homeowners with central AC will be glad to have one of these units on hand when the central AC breaks down during a summer heat wave and the first available service call is several days away. Ready to shop for a portable? Here are some factors to keep in mind when choosing a portable unit. As with any other air conditioner, one needs to know the square footage of the space they want to cool. Most portables will list a recommended square footage for the unit’s capacity. Portable air conditioners Single hose or dual hose portable? Getting the right BTU capacity for the space is critical. One will find several models rated for areas up to 500 square feet. Keep in mind that a space that has multiple sun-exposed windows, a heat producing appliance, or routinely has multiple occupants will have added heat load. If any of these conditions are present, one will want added BTUs to stay cool. Portable air conditioners are either single hose or dual hose design. Single hose models are faster to set up and may have built-in hose storage, so they are easily stored away once the season ends. They’re a great choice for spot cooling or in areas that have moderate summers. However, single hose models, by design, must intake and exhaust air through the same hose. Warm outside air is mixed in with indoor air and over time will produce a ‘warming effect’ if outdoor temperatures are extremely high (above 950 F). permanent cooling solution Is there a window to vent air to the outdoors? The kit has either one or two expandable hoses, and a frame that fits into the window with knockouts for the hose On two-hose portable models, one of the two hoses is dedicated to removing heat (exhaust) and expelling it outside. Intake air comes from the room that is being conditioned so the unit will maintain comfort even in extreme heat. Dual hose portable air conditioners will cool more quickly and efficiently. Dual hose portables are a great choice for all climates and are even suitable if one will be using the unit as a permanent cooling solution. Portable air conditioners must be vented to the outdoors. The units come with a window installation kit. The kit has either one or two expandable hoses, and a frame that fits into the window with knockouts for the hose(s). The hose kit will install into most standard windows. The hoses snap or twist and lock into the kit frame and into the back of the unit. Most flexible hoses can extend from 24-60 inches. installation kit hoses Is there a proper electrical outlet near the window? Venting through a drop ceiling may be an option in certain circumstances, however additional hose(s) may be necessary to reach ceiling height. One will also want to make sure the ceiling opening is well sealed to maintain proper cooling and venting of hot air. Portable units will plug into a standard 115v wall outlet, but one will want to make sure the wall outlet is close enough to the window so the power cord of the unit will reach the outlet, and the unit remains close enough to the window to utilize the installation kit hoses. Otherwise, one will have to hire a qualified electrician to install the outlet. Typical power cords are 6-7 feet in length.

Portable Technology Brings Cooling Solution To HVAC Market That Offer Spot Cooling And Supplemental Air Conditioning
Portable Technology Brings Cooling Solution To HVAC Market That Offer Spot Cooling And Supplemental Air Conditioning

Traditionally, portable cooling technology has been seen as a quick fix to immediate cooling needs. If a customer’s air conditioner went out in the busyness of summer, portable cooling could keep the customer comfortable until a technician could arrive at their home. Such needs and uses for portable cooling still exist, but over the past few years, portable cooling has increasingly developed as a solution for unique cooling needs. Manufacturers are saying this trend will continue. Misty Wilburn, Marketing Manager for Portacool, said that the market’s renewed interested in employee safety and productivity is driving further demand for portable cooling solutions. portable evaporative cooling From a safety standpoint, employers are looking for solutions that reduce heat stress and keep their employees cool" “From a safety standpoint, employers are looking for solutions that reduce heat stress and keep their employees cool,” she said. She explained that the industry is seeing a large shift surrounding employee safety. The California Division of Occupational Safety and Health (Cal/OSHA) has led this charge by putting regulations in place regarding indoor and outdoor working conditions and will likely be followed by other states. “For operations that can’t use conventional a/c because of cost or efficiency, portable evaporative cooling - in setting up cool-down stations - can be key to meeting a lot of those regulations,” she said. In addition to this, she said that companies will be able to attract and keep the best employees if they provide a great work environment. open or closed environment “Offering those portable cooling areas can keep up focus and morale, which overall increases the profitability of your workforce,” she said. Wilburn explained that contractors can offer this solution as one that will do the most for their customers while also being conscious of cost. When choosing portable systems for their customers, Wilburn advised contractors to take note of the size of the space that needs to be cooled, the number of employees, electrical options, presence of a water supply, and whether it is an open or closed environment. multiple large coolers “By strategically positioning multiple large coolers, you can cool an entire area where you have lots of employees working,” she said. “If you want to spot cool an area and take the product wherever the work takes you, using one single smaller cooler might be the better option.” In agriculture, portable cooling has been used to cool individual stalls, especially for show animals All in all, she told contractors that it is important to choose a product that is as versatile as possible for the work environments the customers will find themselves in. Contractors should ensure the cooler is a plug-and-play model that can be set up with little technical skill needed. The degree of maintenance required is also important, as well as the expected lifespan of the equipment. Contractors should widen their view of portable cooling applications, too. Portable as Supplemental Cooling “Evaporative cooling is effective in other applications such as farm agriculture, patios, gyms, outdoor venues, events, sports sidelines, offshore platforms, retail stores, rental car pickup facilities, airports, beer gardens, and fast food lines for outdoor employees,” she said. In agriculture, portable cooling has been used to cool individual stalls, especially for show animals. “Is it dependable?” said Brittany Calderon, Product Manager for Friedrich Air. “Is it quiet? Is it energy-efficient? Those are the three main things that we hear our customers looking for. And of course, cost is always a factor.” Portable cooling can be used to keep areas of a home comfortable when the main air conditioning unit goes out. Applications for Portable Cooling “We recommend that contractors all keep a portable in the back of their truck to allow for supplemental cooling,” she said. “If somebody’s a/c goes out and they need to order a part, it’s going to take a few days. They can leave one of those portables at that customer’s house and everybody’s happy.” She said that portable cooling is often used to supplement other cooling systems Calderon said that a dual-hose portable air conditioner offers a really good solution for customer’s needs; it’s designed to cool areas faster, more efficiently, and without a complicated installation process. She said that portable cooling is often used to supplement other cooling systems. For example, 2019 had a relatively mild summer in the Northeast, and Friedrich saw interest grow in portable cooling - equipment that people could stow away in a closet when not in use. electrical equipment rooms Mike Renier, Vice President of Sales for KwiKool, said that customers are realizing that portable cooling can be used for specific, unique applications, and contractors should keep that in mind. “As the market has evolved, customers have gotten more demanding and not less,” he said. “And what that boils down to is that they’re looking for tailor-made solutions to application problems.” Some examples of this, he said, include server rooms, electrical equipment rooms, and other high-tech areas where heat-generating equipment needs to be kept cool. These rooms generally have permanent systems in place to cool the equipment; however, these mechanical systems run the risk of occasional failure when components break. redundant permanent systems The technology, called Biocool, is designed for use in laboratories and hospitals “Customers don’t want to have to spend a tremendous amount of money having redundant permanent systems in place,” Renier said. “As an alternative, they can look to portables to supply the duplicated air conditioning.” To operate as intended, such portable equipment will need to have high-efficiency, sensible capacity that can match the heat load, which contractors should look for. A portable cooler with a 1-ton heat load, he explained, will not be able to cool a room with a 5-ton heat load. Portable technology should always be used with the end goal in mind. For example, KwiKool has developed a portable cooler with a hospital-grade HEPA filter and UV light system. The technology, called Biocool, is designed for use in laboratories and hospitals. temporary air conditioning In other applications, cooled air must be moved long distances before it can be exhausted. Portable coolers, when properly designed to pump air further distances, can be temporarily installed in attics. On hot summer days, when attic temperatures can exceed safe temperatures, a portable cooler can be used to keep the heat tolerable for any employees working in that space. Renier reminded contractors that there is a big division between residential and commercial portable cooling products. “If all you want is some cheap, temporary air conditioning for a bedroom, those personal air conditioners are great,” he said. “But if you want to bring the serious capacity for a high-profile application, don’t buy the cheap stuff. It won’t work. You’re getting what you pay for.”
