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.
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.
