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.

Why Hybrid Heat Pumps Deserve Their Moment In The Spotlight
Why Hybrid Heat Pumps Deserve Their Moment In The Spotlight

With the UK committed to reducing greenhouse gas emissions to zero by 2050, drastic action is needed by the government. For new-build homes, there’s a gas boiler ban coming in less than five years’ time. And for older properties, it’s likely that gas prices will continue to rise, to encourage homeowners to switch to a more sustainable alternative. Renewable heating market With this in mind, the renewable heating market is growing rapidly, albeit from a very small base – but with targets in place to keep the momentum up. The government has committed to install 600,000 heat pumps into new homes by 2028. The government has committed to install 600,000 heat pumps into new homes by 2028 People who are already living in (old and new) properties heated by renewable technology should be applauded for pioneering it – but understandably, not everyone has the confidence to give up a solution they’re familiar with, and to step into the relative unknown. And that’s why the value of transitional technologies cannot be over-estimated– both to homeowners who want to live more sustainably and to installers looking to adapt and future-proof their businesses. But the role that hybrid heat pumps can play in accelerating progress on the road to zero has been somewhat overlooked to date. Hybrid heat pumps Hybrid heat pumps combine the power of a heat pump with the familiarity of a high-efficiency boiler. The two appliances work together to provide heating and hot water, providing the ideal replacement for a combi boiler as a first step towards introducing renewable heating technology into the home. Compared to a traditional gas boiler, hybrid heat pump systems can reduce CO2 emissions by as much as 55% and have been proven to deliver up to a 50% reduction in energy bills in homes in the UK. Our Daikin Altherma hybrid heat pump’s smart programming helps to save up to 35% more energy than a traditional condensing boiler by automatically determining the most economically and energy-efficient operating combination based on energy prices, outdoor temperatures, and indoor heat capacity. Heat pump share The hybrid system’s operating mode can be shifted to more electric heat pump share As well as being quick to install, hybrid systems are designed to look and operate like a conventional boiler system and deliver like-for-like performance and comfort levels. And to give homeowners peace of mind, the heat pump can act as a back-up for the boiler, and vice-versa – meaning they’ll never be caught short. Hybrid systems are best-suited to smaller homes in urban areas, that are likely to have a combi-boiler, and where the shell of the building is not energy-efficient enough to rely on electricity alone. But as the efficiency of the building is improved and upgraded over time, the hybrid system’s operating mode can be shifted to more electric heat pump share. And while there’s a lot of talk about new homes in the renewable heating debate, hybrid technology is ideal for renovations and boiler replacements. Heating system replacements We estimate that there are 1.1 million homes across the country that would be well-served by a hybrid system. That, combined with the benefits of hybrids for both installers and consumers, is why we firmly believe in hybrid heat pumps’ potential to support a faster, easier, and more affordable transition to low carbon heating in this country. Every homeowner who buys a Daikin Altherma hybrid system gets a high-efficiency boiler for free When consumers are looking at heating system replacements, we know that complexity and disruption are barriers to purchase. Fortunately, neither is an issue with hybrids. While hybrid heat pump systems can be installed with a household’s existing boiler, to help increase uptake, we’re running a special offer at the moment whereby every homeowner who buys a Daikin Altherma hybrid system gets a brand-new, high-efficiency boiler for free. Low carbon technology And there’s no need to lose valuable floor space to a hot water cylinder or to make changes to the radiators. Hybrids aren’t just good news for homeowners; they represent a real opportunity for installers, too. At the moment, there are 1,000 heat pump installers in the UK and around 125,000 gas boiler installers. We need to transition these boiler installers towards low carbon technology – not just to drive progress on the road to net zero, but to help their businesses stay relevant and competitive. This year, in partnership with 11 of our Daikin Sustainable Home Centres across the UK, we’re running a free nationwide training program to help installers enter the renewable heating market with hybrid heat pumps. eco-Friendly hybrid solution Reducing electricity prices isn’t enough to encourage people to change the way they heat their homes Installers who complete the day-long course can expand their portfolio and gain the skills to upgrade customers to an eco-friendly hybrid solution. Reducing electricity prices isn’t enough to encourage people to change the way they heat their homes; more needs to be done to make new, clean technologies accessible and appealing. We’re doing what we can to incentivize homeowners – and installers – to embrace the possibilities of a hybrid heat pump system, but a clear funding mechanism from Government is needed as well, specifically to help with the upfront cost of upgrading (free boiler or no free boiler). While the now-closed Green Homes Grant explicitly included hybrid heat pump technology, there’s a big question as to whether the same hybrid solutions will be included in the Clean Heat Grant – the details of which are expected later this year. The answer to that question needs to be ‘yes’.

The Role Of Next Generation Refrigerants In Economic And Environmental Recoveries
The Role Of Next Generation Refrigerants In Economic And Environmental Recoveries

A landmark UN scientific study has once again highlighted the short window available to prevent irreversible climate change. Businesses are coming under pressure to dramatically accelerate their net-zero carbon initiatives. This comes at a time where market dynamism is returning across a range of key sectors following a downturn triggered by the pandemic. Businesses are also being pressured by stakeholders to recover revenues lost during the pandemic and to start rebuilding commercial activity. Typical supermarket products With refrigeration sitting at the heart of some of the biggest industries across the globe, including food commerce, healthcare, manufacturing and technology, decisions on refrigerant technology tap into the heart of the debate around environmental credibility, consumer expectations and economic recovery. So how can businesses balance the need to adopt more environmentally-preferable refrigerants with the urgent need to boost revenues? The technology factors into many of the most important facets of modern society Often when you think of refrigeration, you instantly think of cold storage and supermarket refrigeration. Without refrigerants, we wouldn’t be able to extend the life of many typical supermarket products or have the convenience of home storage. However, that isn’t the only role refrigeration play in our daily lives. In fact, the technology factors into many of the most important facets of modern society. The healthcare sectors, for example, would struggle to reduce the spread of infection without the use of modern air-conditioning, while the pharmaceutical industry requires refrigeration to store life-saving medications. Preserving human life On top of this, the digital revolution would not be possible. Without coolants, the data centers run by companies such as Amazon, Facebook and Google would overheat, resulting in system failures and service outages. And finally, with temperatures rising across the planet because of global warming, and heatwave events becoming more common, refrigeration is increasingly important to preserving human life. Without refrigerants, recent extreme weather events would have been even more devastating. However, although refrigeration has been a solution for many human challenges, finding a refrigerant that is both safe and environmentally preferable is a challenge. In fact, before recent breakthroughs, many of the chemicals used as refrigerants, such as ammonia, sulphur dioxide, carbon dioxide and methyl chloride, were poisonous, corrosive and even explosive. Non-Flammable alternative CFCs were found to be extremely harmful to the ozone layer and were therefore phased out In the 1930s, a compound called chlorofluorocarbons (CFCs) was commercially introduced as a non-toxic, non-flammable alternative to established refrigerants and was in widespread use for a variety of applications by the mid-20th Century. However, CFCs were found to be extremely harmful to the ozone layer and were therefore phased out in favor of hydrofluorocarbons (HFCs). The story wouldn’t end there, however, as HFCs were found to be potent greenhouse gases with high global warming potential (GWP). EU regulators therefore demanded their phase-out from 2016. By 2024, HFCs must be phased out so industries have been scrambling to find alternative low-global-warming-potential solutions. Unique chemical bonds The answer came in the form of hydrofluoroolefins (HFOs), developed by renowned chemist, Rajiv Singh. HFOs are known for their unique chemical bonds, which allow them to break down in just a few days, so they don’t linger in the atmosphere if released and therefore don’t meaningfully contribute to global warming. Since launching its Solstice line of HFO refrigerants in 2012, Honeywell has averted the production of more than 200 million metric tons of greenhouse gases, equivalent to emissions from more than 42 million cars, more than all passenger cars in Germany. Honeywell has averted the production of more than 200 million metric tons of greenhouse gases The automotive industry was one of the first sectors to recognize the strengths of HFOs. During the past 10 years, nearly 75 million cars made in Europe have been fitted with HFO-based air conditioning systems. Supermarkets have also been reaping the benefits; more than 30,000 grocery stores currently use Honeywell’s non-flammable HFO refrigerant, Solstice N40, reducing their energy consumption by 10% and their global warming potential by a factor of three. Residential heat-Pumps HFOs are on the brink of being adopted for domestic use as well. New Honeywell HFO solutions are ideal for residential heat-pumps which enable the elimination of fossil fuel burning in our homes, for heating and for hot water generation. HFOs superior performance deliver ‘best-in-class’ energy efficiency, hence enabling heat pumps to generate more renewable energy from the waste heat vs. alternative solutions. As enablers for energy efficient solutions and systems, HFOs also offer unique opportunities for future developments such as domestic air conditioning, cooling of electronic vehicle batteries and the fast growth of data center cooling. The ‘Green Deal’ is EU flag ship regulation on climate and economy recovery. Overall, buildings are responsible for about 40% of the EU’s total energy consumption, and for 36% of its greenhouse gas emissions from energy. Greenhouse gas emissions These new regulations and the corporation sustainability goals create a range of new opportunities To make it specific, heating and cooling, in the EU is responsible for 80% of energy consumed in residential buildings. Rapid adoption of Heat pumps and improved energy efficient solutions; are key contributors for Europe to reach the ‘Green Deal’ goal of being carbon neutral by 2050 and the recently adopted accelerated ‘fit for 55’ goal to reduce net greenhouse gas emissions by at least 55% by 2030. Adopting Low Global warning refrigerant, safe & energy efficient cooling solutions and replacing fossil fuel burners with heat pump systems to generate heat; are also key contributors to corporations’ sustainability goals (ESG). These new regulations and the corporation sustainability goals create a range of new opportunities for HFO solutions. As the popularity of HFOs grows, they’ll have a major role in mitigating climate change and enabling a carbon neutral economy. Pharmaceutical supply chains Happily, what’s good for the environment is also good for the economy. HFO production is already creating thousands of long-lasting jobs. The global pandemic stopped many people from enjoying a range of everyday pleasures such as visits to sporting events, restaurants and cinemas; activities at venues that are often reliant on some form of air conditioning and refrigeration, a sharp reminder of the role played by modern refrigerants. The technology continues to develop and evolve ensuring that a range of activities can continue to happen. From protecting the food and pharmaceutical supply chains to ensuring the continued operation of modern communication technology, next generation refrigerants will support some of the most important parts of the modern economy and a better environment.
