Air Source Heat Pumps are a very efficient way of providing heat for your hot water or heating system by extracting heat from the air outside and transferring it into a building. They work in a similar way to refrigerators, but in reverse. They are similar in appearance to air-conditioning units and are fitted to the outside of a building.
HOW DOES AIR SOURCE HEAT PUMPS WORK?
An air source heating system absorbs low grade heat (not very warm air) from the atmosphere and transfers it into high grade heat (hot air) to heat radiators, under floor heating and water systems. They are so efficient that they can continue to extract heat from the air in temperatures as low as -15°C!
HOW MUCH HEAT CAN I GENERATE?
Heat pumps are around 300% efficient. This means that for every unit of energy used by the heat pump in operation, three or more units of heat are generated for use in a building. They are suitable for properties which are well insulated such as newer homes and those renovated to a high standard.
A well designed heat pump system will provide all your heating and hot water requirements. It is essential that a design survey is carried out on your building to establish the heating requirements of the building and therefore the size of heat pump required
WHAT ARE THE FINANCIAL BENEFITS AND INCENTIVES?
As well as the savings on your annual energy bills, heat pump installations benefit from the Renewable Heat Incentive (RHI). This means that the government will pay you to generate your own heating and hot water.
Provided your home meets certain scheme requirements you can receive around a third of the cost back over 7 years subject to scheme terms. We can work out an estimate of this cost from your Energy Performance Certificate or via the OFGEM online portal.
Air Source Heat Pumps, like most renewable energy systems are subject to the lower VAT rate of 5%.
