Air Source Heat Pumps
Air Source Heat Pumps - What Are They & How Do They Worl?
Air source heat pumps (ASHPs) absorb heat from the outside air to heat your home and hot water. They can still extract heat when air temperatures are as low as -15°C.
Air source heat pumps need electricity to run, but because they are extracting renewable heat from the environment, the heat output is greater than the electricity input. This makes them an energy efficient method of heating your home

How Do Air Source Heat Pumps Work?
Air source heat pumps (ASHP) is a process that by using the principle of vapour compression, transfers the hot air from a place to another exactly in the same way as the system of a refrigerator does.
An air source heat pump works much like a fridge operating in reverse to heat your home. Outside air is blown over a network of tubes filled with a refrigerant. This warms up the refrigerant, and it turns from a liquid into a gas.
This gas then passes through a compressor, which increases the pressure. Compression also adds more heat – similar to how the air hose warms up when you top up the air pressure in your tyres.
The upfront cost of an air source heat pump is something to consider. The pump itself can cost around £9000, with installations costs to be added. However, it’s by far the most efficient and green long term option to heat your home. Consider this: for every 1kw of energy an air source heat pump uses, it can create 4kw of heat energy. That makes it 400% efficient compared to oil and gas, which is 90% efficient at best.
You will always make your money back with an air source heat pump, in two ways:
- Fuel costs will be dramatically lower, forever
- With the RHI scheme, you will be able to claim back quarterly payments totalling thousands of pounds over the following seven years.

Advantages of Air Source Heating
There are numerous benefits to using air source heat pumps to heat your property. Air source heating is a great alternative to traditional heating methods and could save you money, particularly if you live ‘off grid’ and have a well insulated property. Here are some of the advantages to air source heating:
Whilst there are many positives, there are also other factors to consider when investing in an Air Source heat system:
Most frequent questions and answers
If you have radiators in your home, and you’re switching from a gas-fired heating system to an air source heat pump, you’ll probably need to buy some bigger radiators to keep your house warm
It looks a bit like an air conditioning unit, but sits on the floor outside your house. So you’ll need to have some outdoor space preferably in a sunny area – for it to be located. You will also need to consider space for a water tank inside your home. If you don’t have room for a water tank then a hybrid heat pump might be the way to go
Yes, quite possibly. Please bear in mind that for the best energy efficiency you may need to consider upgrading your home’s insulation. Our retrofit co-ordinator would be able to advise you on the best solutions for your property.
