An air to air heat pump is a specific type of air source heat pump that absorbs heat from the outside air to distribute in your home, usually via a ventilation fan system.
Air source heat pumps are often considered a renewable energy system as they use significantly less energy than a conventional system. As with all heat pumps, it is able to provide both heating and cooling for your home.
This type of heat pump is not only sustainable and efficient but also one of the most affordable heat pumps on the market. In the long run, it will allow you to cut your heating bill by £290 yearly compared to an old G-rated boiler, and furthermore:
If you’d like to replace a gas boiler with a heat pump, you’re well on your way to significantly lowering your energy bills, with heat pumps being an excellent alternative for your home in light of any eye-watering energy prices.
Air source heat pumps essentially work by using the principles of vapour compression refrigeration to absorb heat in one place and release it to another. In this case, it means extracting heat from the outside air and using it to warm the inside of a building via fans.
The efficiency of ASHP depends on the size of the building, the specific model, and the type of technology used.
The video below illustrates how the process works.
The air to air heating process can also be reversed in the summer to cool the building.
The average air to air heat pump cost in the UK is £5,000–£10,000. And for households of 2-4 people the installation and running costs range from £6,900–£8,700.
|Installation cost||Avg. annual running cost||Annual maintenance cost|
The larger the house, the larger the heat pump required to maintain the indoor temperature, and the more expensive the installation cost will be. Here are the approximate air to air heat pump costs based on the house size.
|Household size||Avg energy/gas consumption (kWh)||Installation cost||Running costs*|
Just as with any energy system, there are different pros and cons of air to air heat pumps that change per household. Together with the air to air heat pump efficiency, here are some factors to consider that will affect the running costs:
A gas boiler will incur annual costs of £1,250 for the typical UK household. In contrast, a highly efficient heat pump will result in annual heating expenses of around £1,360.
Yet let’s not forget boilers provide heating options only. If you cool your home during summer with an air conditioning system, prepare to pay another £400 for it.
Overall, when it comes to the “air to air heat pump vs air conditioner” debate, the former offers both heating and cooling capabilities, making it a versatile choice for climate control.
|Heating system||Yearly running cost|
|Gas boiler + Air conditioning unit||£1,650|
|Air to air source heat pump||£1,360|
By transitioning to the air to air heating system, in the long run, you will incur lower expenses with it compared to the combined costs of a gas boiler and an air conditioning unit, enjoying yearly savings of £290 for an average household.

The installation process of an air to air heat pump is considered to be fairly straightforward, especially when compared to other heat pump types. This means the air to air heat pump installation is also cheaper.
|£5,000–£10,000||£1,600 – £3,100|
Unlike an air to water heat pump, an air to air heat pump only needs the outdoor unit that extracts ambient air, and the indoor unit to expel that air as heating (or cooling). You will not need to have radiators or extensive pipeworks installed, as you would with the air to water system.
The efficiency of any type of air-source heat pump is measured by the Coefficient of Performance (CoP). The CoP value, the better: for example, the CoP of air to air source heat pumps typically ranges from 2.5 to 4.
A CoP of 4, for instance, means that the heat pump produces 4 units of heat energy for every 1 unit of electricity it consumes.
In simpler terms, for each kWh of electricity used, 4 kWh of heating energy is created. You can calculate the air source running costs using the following formula:
(Average yearly heating requirement (kWh)/CoP) x27p*
* Electricity price as of October 2023
For example, an air to air heating system with a CoP of 2.5 can result in the following running costs for various properties in the UK:
|Household size||Avg yearly heating requirement (kWh)||Estimated air to air heat pump running costs|
Keep in mind these numbers are rough estimates and a personalised calculation is highly advisable. Seek professional advice to get a clearer picture of how much running an air to air heat pump at your property will cost you.
CoP is very dependent on the outside air temperature. Usually, the CoP of air source heat pumps is fairly stable between 2–3, if the outside temperature ranges between -3°C to 10°C.
What this means is that, in very mild weather, the heat pump CoP is higher and the machine works efficiently. On colder days it is quite the opposite: it will take the heat pump more work to transfer the same amount of heat, hence the CoP will be lower.
Air source heat pumps are considered an efficient heating option in the UK. If properly installed and combined with the right components, it can be just as efficient in warmer as well as colder UK regions. For instance, most of the modern air to air heat pumps use inverters to reduce wear and tear of the heat pump and to increase the CoP.
Yes, the Boiler Upgrade Scheme (BUS) is just one of the many heat pump grants eligible to be used with an air to air source heat pump. With the Boiler Upgrade Scheme (BUS) you may be eligible to receive up to £7,500 to assist with the upfront costs of an air to air source heat pump. This means getting an air to air heat pump in the UK has become more accessible and affordable.
The eligibility criteria for this grant are as follows:
*Homeowners with outstanding recommendations for loft or cavity wall insulation may still apply if the installation of these forms of insulation was completed during the voucher validity period, as indicated by a newly generated EPC at the voucher redemption stage.

✘ Seasonal dependency. Air to air heat pumps are dependent on the outside air temperature. They work most effectively if the outdoor temperature is between -3°C and 10°C. When the temperature drops to -10°C or below, the electric power consumption of the pump increases. Luckily, UK temperatures don’t usually drop this low.
✘ Dust. Due to using fans to distribute heating/cooling, the dust contained in the air may move throughout the room.
✘ Lower supply. It provides a lower heat supply compared to oil or gas boilers, meaning that you would need bigger vents.
✘ Extra expenses. If you live in colder parts of the country, you would need to invest in some additional elements, to ensure optimal results and electricity usage of the heat pump. However, the additional parts are not high in cost, hence it is not a huge disadvantage – and they pay off in the long run.
An air to air heat pump is a great choice for heating and cooling your home. It is suitable for most homes, but to install an air to air source heat pump, you should consider several criteria.
