Pros and Cons of Air Source Heat Pumps

What Is an Air Source Heat Pump?

Heat is transferred from the outside air to an indoor room via an air source heat pump (ASHP). Domestic hot water is produced and radiators are heated by using wet central heating systems. Heat is absorbed by heat pumps, which then transfer that heat to another medium, much like a refrigerator does.

Some air source heat pumps can function in the summer as a cooling system as well. The majority of the time, they are installed outside a building where there is enough room.

Measuring-Pros and Cons

There are two main types of air source heat pumps:

Before making the switch, consider both advantages and disadvantages of air source heat pumps.

10 Pros of Air Source Heat Pumps

  • Low Carbon Footprint
  • Save Money on Energy Bills
  • Eligible for RHI
  • Can Be User for Heating and Cooling
  • Can Be User for Space Heating and Hot Water
  • High Seasonal Coefficient of Performance(SCOP)
  • Easy Installation Process
  • Low Maintenance
  • Long Lifespan
  • No Fuel Storage Needed

6 Cons of Air Source Heat Pumps

  • Lower Heat Supply Than Boilers
  • Extra Spending to Install Underfloor Heating
  • You Home Must Be Well-Insulated Already
  • Lower Efficiency Below 0 degree Celcius
  • Lower Savings Compared to Low Price Mains Gas
  • ASHPs Can Be Noisy

The UK government wants to install 19 million heat pumps in new construction to reach Net Zero by 2050. The UK government's heat pump incentives make this renewable energy source even more affordable to use and lighten the financial strain of air source heat pumps as the deployment of heat pumps rises.

In its most recent special study, the International Energy Agency emphasizes that no new gas boilers should be sold after 2025 if Net Zero targets are to be met by 2050. In the near future, heat pumps are anticipated to be a superior, low-carbon option for heating homes.

Advantages of Air Source Heat Pumps

The use of heat pumps has many advantages. Comparing an air source heat pump to a gas or electric heating system, you can save money on energy costs and lessen your carbon impact. The adaptability and affordability of air source heat pumps are two of its main benefits. An ASHP can be used for space heating or water heating, and can function for both heating and cooling.

The most important advantages of purchasing an air source heat pump are the following:

Disadvantages of Air Source Heat Pumps

You should be aware that air source heat pumps have a lesser heat supply than other options, which is a significant drawback. You would therefore make the most of your ASHP, according to this. In addition to having underfloor heating, your home must be well-insulated. In addition, air source heat pumps can be noisy, which is another typical issue. This means that where you place those matters a lot.

These are the main air source heat pump disadvantages:

Factors to Consider Before Installing an ASHP

When thinking about installing air source heat pumps, one must consider three main factors:


An air source heat pump installation typically costs £8,000 to $18,000. Depending on the system type chosen (and whether you need cooling in addition to heating), the size of your house, and your particular needs, additional fees can be spent. Compared to ground source heat pump costs, which range from £20,000 to £45,000, these expenses are significantly less expensive.


It is critical to have a well-insulated home, especially one with loft insulation, to have substantial returns on savings. This makes sure that the heat produced inside the house stays inside, keeping it continuously warm throughout the winter.


To guarantee that the heat pump is installed properly, choosing the right installation is crucial. You should use due investigation, including confirming that the installation is being charged a reasonable price and has the required certifications.
