Air Source Heat Pumps


Air source heat pumps provide heating and hot water in a cost effective and sustainable way.

A heat pump can save you a significant amount on your fuel bills. It will also greatly reduce your carbon footprint, as heat pumps generate heat from the natural air, which is continually in plentiful supply.               

How an air source heat pump could benefit you

Energy Bill Savings

Air source heat pumps are extremely efficient and much cheaper to run than traditional heating systems. You will be generating your own heat using just a small amount of electricity and taking free heat from the air around the heat pump.

Protection from rising energy costs

Energy costs are anticipated to rise considerably in the next few years - you can protect yourself against rising costs by producing your own heat from a renewable source.

Get paid for the heat you generate 

With the UK Government's Renewable Heat Incentive scheme, you will be paid for all of the heat your air source heat pump generates. Renewable Heat Incentive payments are made to you quarterly for 7 years and are tax-free and increase in line with inflation. The Renewable Heat Incentive ensures your system pays for itself in typically under 7 years.

Preserves the environment   

Switching to renewable energy helps to reduce pollution, lessen our dependence on finite fuels and reduce your CO2 emissions.

Fuel Independency

Heat pumps eliminate the need to have fuel delivered to your property and you won't need to worry about running out of fuel. This makes air source heat pumps a much more convenient renewable option than a biomass boiler.

Highly Efficient

An air source heat pump can convert 1 kilowatt of electricity into 2.5 kilowatts of heat, by taking 1.5 kilowatts of electricity from the air. For comparison, an A-rated combined boiler can only turn 1 kilowatt of gas or oil into 0.9 kilowatts of heat.

Anticipated Return on Investment over 20 years for an Air Source Heat Pump

Figures are based on the generation of 18,000 kWh of heat and a previous fuel type of oil. Read more about the installation here.

How they work

An air source heat pump will extract heat from the outside air, converting it into high grade heat by passing it through a compressor where its temperature is increased. The heat is then used for space heating and hot water. An air source heat pump will work at temperatures as low as -20°C. 

Air source heat pumps are very efficient; they can convert 1 kilowatt of electricity into 2.5 kilowatts if heat, by taking 2.5 kilowatts of electricity from the air. For comparison, an A-rated combined boiler can only turn 1 kilowatt of gas or oil into 0.9 kilowatts of heat.

Air source heat pumps are installed outside of your home and can be fitted to a wall of placed on the ground. To get a good flow of air, they need plenty of space in front of them. You air source heat pump installation must be specified and designed for your home by an experienced professional like Solarwall, to ensure the maximum efficiency of the system.
