The UK’s heating system stock is currently largely dependent on mains gas, oil and LPG systems. Around 85% of homes in the UK have boilers that use natural gas, giving off carbon dioxide when burnt. Within the UK, 20% of carbon emissions are being generated by heating buildings, and a national target of achieving net-zero emission by 2050, a greener way to keep homeowners warm is needed.
Heat pumps are seen as the solution from the UK Government and homeowners; these renewable systems work by utilising electricity to extract heat from the air or ground and use this warm water in radiators or underfloor heating systems.
How Do Heat Pumps Work?
A heat pump is a device that transfers heat from an external source, such as the heat in the air or ground to another location, such as your homes central heating system. For example, air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems and hot water in the property, whether it be a home, building or school.
An Air source heat pump (ASHP) works a bit like a refrigerator in reverse. The process consists of an evaporator, a compressor and a condenser. The ASHP absorbs heat from the outside air into a liquid at a low temperature, then the heat pump compressor increases the temperature of that heat. In the condenser, the hot liquid’s heat is transferred to your heating and hot-water circuits so you can use it to warm up your premises or home.
What Are The Benefits Of Heat Pumps?
- Lower running and fuel costs, particularly if you are replacing a conventional fossil fuel system
- Lower carbon emissions, giving a better environmental impact
- Increased safety when compared with combustion-based systems
- High reliability, heat pumps offer a long-life span and a steady source of heat
- Minimal maintenance required
- Eligible for grants and incentives
Our in-house engineers install market-leading models from Mitsubishi and Mastertherm, which run more quietly than a typical domestic refrigerator. Heat pumps are fully capable of matching the same water temperatures as traditional boilers, but due to their longer-term, more efficient operating cycles, they don’t need to do so in order to keep rooms warm, particularly when combined with suitable radiators designed to perform with the lower flow rates.
Heat pump systems are an incredibly efficient means of generating heat as for every kilowatt of electricity given to a heat pump, it will create between 2-4 kilowatts of heat, making heat pumps up to four times more efficient than traditional heating systems.
What Lies Ahead For The Future Of Heat Pump’s ?
The opportunity that heat pumps present to reduce carbon emissions associated with heating is already well understood by policymakers and is reflected in buildings legislation.
The Future Homes Standard are seeking to ensure that new homes built from 2025 will produce up to less than 75% of CO2 emissions than homes delivered under current regulations. No new homes will be able to connect to the gas network from 2025 and will be required to utilise a low-carbon heating source, such as a heat pump.
Meanwhile, many homeowners of existing properties are already making the transition, with heat pump installation numbers last year already at 120% of 2019 levels. The growth of heat pumps will continue with supported government funding. The current grant is the Domestic Renewable Heat Incentive (RHI), who offers quarterly payments over a period of 7 years, based on the amount of heat generated.
This scheme will be closed to new applications on the 31st March 2022 but will be replaced by the Boiler Upgrade Scheme. This new scheme will offer grants of up to £5,000 for air-source heat pumps, and £6,000 for ground-source installations from a total fund of £450 million when it launches in April 2022.
