An air source heat pump works by using the outside air to heat a refrigerant, which then transfers the heat to water in a tank. Heat pumps deliver water at lower temperatures that conventional gas boilers. Usually between 35 – 45ºC as opposed to 75ºC from a gas boiler, this is still more than adequate to heat your home.
A fan sucks in air and passes it over a refrigerant. The refrigerant used boils at a very low temperature, so even very cold air as low as -25ºC has enough energy to be heat the refrigerant. The pump also compresses the air to heat it further. The heating and hot water is controlled from in the house using a thermostat and timer, the same as a standard heating system.
Absolutely! Although heat pumps run on electricity, they generally have a 300% power output. This means that for every 1 unit of electricity used the heat pump will give 3 units of heat, making them 300% efficient and much cheaper to run than a standard gas or electric heating system.
You can also use solar panels to provide free electricity to power your air source heat pump making them even more efficient.
As well as saving money with an ASHP, you may also be eligible to receive funding from the government via the Renewable Heat Incentive (RHI). To be eligible for the RHI scheme you must have your appliance installed by an accredited supplier. Click here for more information in Air Source Heat Pump installation.
Our surveyors are able to answer any questions you may have over installation and suitability.
Because heat pumps don’t heat the water as high as a conventional boiler, they work best with underfloor heating. Heat pumps do work with radiators, but they may need to be larger than your current radiators to compensate for the lower temperatures.
By using a heat pump, you could lower your carbon emissions by up to 70% compared to electric storage heaters. Compared to a conventional gas boiler the carbon emissions can be reduced by up to 60%. By combining your heat pump with a green energy provider and/or with other renewable sources you could reduce your emissions by 100%.
Some houses will be eligible for a grant of up to £7000 paid quarterly by the government. This is being replaced with a single up-front payment of £5000 in April 2022 (but this will no doubt go quickly).
