Why should I Consider an Air Source Heat Pump

Air Source Heat Pumps work by transferring heat taken from the outside directly into an indoor space (home, office, etc.) via the wet central heating systems, which therefore provides heated radiators, and hot water.  Not only that, but in the warmer summer months, air source heat pumps can be used to cool down internal buildings.

If you are searching for an air source heat pump on a building, 9 times out of 10 you will find them on the outside as this usually provides the adequate amount of space that they require to operate properly.

There are generally two types of air source heat pump to choose from:

  • Air to Heat Pump – Takes air from the outside and then transfers that directly into your home via a fan system. This is used to heat a room or other indoor space.
  • Air to Water Heat Pump – Takes the heat from the air outside, and transfers it via the central heating system to give both hot water heating and heating for indoor spaces.

So now that we have that cleared up, let’s have a look at the pros and cons of air source heat pumps…..


  • Low Carbon footprint
  • Can be alternatively powered (using wind or solar energy, for example)
  • Hot water heats up immediately and can be used straight away or saved for later
  • They can last for up to 20+ years if treated correctly
  • No fuel storage required
  • They have a high SEER (Seasonal Energy Efficiency Rating)


  • This type of air source heating actually lowers heat supply when you compare it to oil and gas boilers. Due to this, larger radiators are usually required.
  • If you live on gas mains, then air source heat pumps are not the best option for you, meaning to get the best you will have to look elsewhere.
  • If there is no access to solar energy or wind power, the downside is that they require electricity to work.
  • When they are working they have a similar sound to a running air conditioner, which can be quite loud on occasion.
  • Efficiency is hit during the winter and / or cold periods. This is because they have low COP (Coefficient of Performance) levels.

As always, there are plenty more pros and cons out there for you to read about, but the ones listed above are the most critical for you in the first stage of deciding exactly what you want and need.
