The whole world is starting to wake up to the problems of excessive energy consumption and carbon emissions, and everywhere people are asking what they can do to reduce their own CO2 footprint. There are currently a number of devices that can make your home greener and more efficient, and air source heat pumps are among the most popular.

An air source heat pump will lower your fuel bills significantly, is easy to install and requires very little maintenance. They absorb heat from the outside air and use it to heat radiators, underfloor heating systems or hot water in your home.

How it works

They work on a similar principle as a refrigerator for households. Just as a refrigerator extracts heat from inside, air source heat pumps extract heat from the outside air, even when the temperature outside is as cold as -15c. The heat extracted from the air is absorbed in a liquid that is pumped through a heat exchanger in the heat pump. The low quality heat extracted by the cooling system is then passed through a heat pump compressor and then concentrated to a higher heat temperature which can be used to heat your home.

This type of system consistently provides an even and reasonably high heat temperature to your home, but you may find that you need to keep a standard boiler as a backup during the winter months to really keep the cold away.


An obvious benefit of installing a pump for your home is that it reduces your CO2 footprint. Unfortunately, it requires electricity to power the pump, so it will still have some environmental impact, but the heat it extracts is a completely renewable resource, so it is generally a very green system. It will give you a return on your investment especially quickly if you install it in a house to replace an existing electric or coal heating system. It also has negligible maintenance costs as it is a simple system with very few moving parts.


There are two types of air source systems you need to know about. The first is the air-to-water system, which emits heat via your wet central heating system. These are suitable for emitting heat at relatively low temperatures over a long period of time, so they are ideal for underfloor heating systems or large radiators.

The second type is the air-to-air system. This system heats your home by producing hot air, which is circulated by fans. A disadvantage of the air-to-air system is not very suitable for heating your water.

If the idea of ​​picking energy out of the air appeals to you, you may want to consider getting an air source heat pump for your own home. They may not be considered as efficient as other green heating systems such as photovoltaic systems, but heat pumps will still have a big impact on reducing your energy costs and lowering your carbon footprint.
