All You Need To Know About Air Source Heat Pumps

With the advent of new revolutionary technologies, the products we use keep improving for the better. This can be seen in the new air source heat pumps that offer an eco-friendly way to heat indoors through the use of a low-carbon heating mechanism.

The technology of this heat pump is different from that of a gas boiler. It takes the warmth from the air outdoors and uses a little amount of electricity to heat your house and provide hot water.

When you install an air source heat pump in your well-insulated and energy-efficient house, you will be ensuring a greener future because these heat pumps are much more eco-friendly than gas boilers.

In this way, you will not only be heating your house in an energy-efficient way but also lowering your carbon footprint. So let’s look at how they work.

How do air source heat pumps work?

Air source heat pumps work on the same technology as that used by refrigerators to keep cool but in the opposite way. This heat pump takes in the outdoor air to heat the refrigerant liquid that, when warm, converts into gas.

This gas, in turn, is compressed to elevate the temperature and thus provide your indoors the heat needed to keep warm.

When the heat leaves the gas and it cools down, it will convert to its liquid state again, and then the cycle continues. Air source heat pumps require little amounts of electricity and thus lower Utility Bidder costs as compared to their counterparts, and they can even work in harsh cold temperatures.

What are the benefits of an air source heat pump?

Air source heat pumps are:

  •         Affordable and more cost-efficient than boiler systems,
  •         Better for the environment because they reduce carbon emissions and improve the air quality,
  •         Easy to use with solar panels.

Are there other types of heat pumps as well?

Yes, there is one more type of heat pump in addition to the air source heat pump. These two operate in the same way but the source from which they extract heat is different.

So it’s essential that you know which one is best for you. Here is some difference between the two types of heat pumps that will help you decide.

1)   Air source heat pumps

These require little space to install as the external heat pump unit is small. They are also more affordable and easy to install as compared to ground source heat pumps.

They can work in low temperatures and can work fine for around 20 years. On the other hand, they have higher costs of operating than ground heat pumps.

2)   Ground source heat pumps

These heat pumps have lower costs of operation, but they are more costly than air source heat pumps. They are also more complex in terms of installation since a large area outdoors needs to be excavated to lay down the pipework. Ground source heat pumps work more efficiently in lower temperatures and can also last around 20 years.

In addition to these two, there is another type that is a hybrid of these heat pumps. The hybrid heat pumps are either air source or ground source ones in combination with a gas boiler as a backup for when extra heat is required.


Air source heat pumps are a good way of heating your indoors and ensuring sustainability. Even if you go for any other type of heat pump, you will have a much more efficient heating system as compared to the traditional gas boiler system.
