Air Source Heat Pumps
Air Source Heat Pumps are an efficient way of heating your property, especially for systems such as underfloor heating where the heat is on low for a longer duration and for radiator heating.
Not only can you save money on fuel bills, you could also receive money from the Government’s Renewable Heat Incentive (RHI), reduce your use of fossil fuels and cut your household’s CO2 usage.
How does does it work?
Solar thermal panels use heat from the sun to warm fluid passing through them, as the diagram below shows. This is then used to heat your water, which is stored in a hot water cylinder. An immersion heater/unvented hot water cylinder might be needed as a back-up heater or to get the water to the temperature you want.
What are the benefits?
• Less space is required compared to other renewable products because the main unit is located outside.
• They are generally more cost effective to install than alternative renewable heating systems.
• On a well-designed heating system with under-floor heating and an outside air temperature of 7°C, air source heat pumps can reach efficiencies of up to 5.1kW of heat for every 1kW of electricity used. This is known as the COP (Coefficient of Performance). Electric storage heaters have a COP of 1kW of heat to every 1kW of electricity used.
• Can be used with radiators and under-floor heating systems.
• Only one fuel bill is required for your home as they only require electricity to run.
• Very reliable as there are no hot burners required.
• Applicable for Home Energy Scotland funding
