How Air Source Heat Pumps Works

An air source heat pump uses the outside air and extracts heat from it, which is then used to warm the inside of the house, regardless of the temperature outside. The current system comprises an external unit, which takes heat from the surrounding air, and an internal unit, which circulates the heat.

It is then circulated to the outdoor unit, where it takes heat and evaporates, turning into a gas that is compressed to heat up. This hot gas is then circulated to the indoor unit, which distributes heat to the home heating solutions like radiator or floor heating.

Cost of Installing an Air Source Heat Pump

The installation cost of the air source heat pump will depend on various factors, such as the size of the house, the type of heat pump, and the installation peculiarities. Based on the market, the installation cost of air source heat pumps in the UK is between £7,000 and £13,000 on average. Some of the factors that influence the cost are discussed below:

  • System Type and Size

    It should also be noted that in order to supply large houses, you need more powerful systems, and they are much more expensive. This means that in a typical three-bedroom dwelling, an Air Source Heat Pump might cost between £7,000 and £11,000. Bigger systems that are appropriate for large homes can go for over £13,000, depending on the size of the house.

  • Installation Complexity

    The installation capacity can greatly affect the total cost of the air source heat pump. It is also important to note that depending on the type of heating system that has been used in your home, there might be some additional charges required to modify the heaters for the new system, for instance, from radiators to under floor heating.

  • Location

    Installation costs can also depend on the area in the UK where the installation is to be done. In some instances, installing the equipment in remote or hard to reach locations may attract extra charges.

Cost of Running an Air Source Heat Pump in the UK

Air source heat pumps indeed have some amazing features, among which efficiency is inarguably one of the most prominent. Normally, an Air Source Heat Pump can directly output 3 to 4 units of heat for one unit of electricity, which is as high as 300-400% thermal efficiency more than the ordinary hot water boiler.

However, running costs will depend on several factors, such as:

  • Electricity Prices

    One primary consideration to understand about Air Source Heat pumps is that they depend on electricity; therefore, the running cost will depend on the electricity tariffs in your region. However, in some cases, electricity is comparatively costlier than gas.

  • System Performance

    There are a number of things that can influence the efficiency of an air source heat pump; these include the climates outside and the layouts of the building. It explains how good insulation coupled with draught-proofing boosts the efficiency of the system and, consequently, the overall working cost.

  • Maintenance

    Just like any other heating equipment, an air source heat pump requires a routine maintenance so that it will last long and function effectively. The annual costs of servicing vary from £100 to £200 depending on the condition, where it is located, and other factors.

  • Replacement of Parts

    which includes rectification of the parts that may wear down over time and replacement of other components that may well be required over the useful life of the system, which ranges between 15 to 20 years nationally.

Potential Savings on Installing Air Source Heat Pumps in the UK

The costs of incorporating an air source heat pump system in the building may at first appear more costly than other systems because it may require a high initial investment but, on the other side, may lead to low energy power bills in the future.

Energy Saving Trust mentions that UK homeowners can save between £475 and £735 per year if they replace their old electrical heating devices with air-source heat pumps.


The process of considering the costs and benefits of an air source heat pump and then making a decision to install the device improves the eligibility of the residence for energy efficiency and enhances environmentalism in a positive way.

There is nothing wrong with saving on energy bills in the long run, not to mention helping the environment by adopting air source heat pumps as a strategic step for homeowners in the UK.
