Air Source Heat Pumps – What Are They?

Are you looking for an eco-friendly, cost-effective way to heat your home or business? An Air Source Heat Pump could be an ideal solution. 

In this article, we’ll dive into the benefits of air source heat pumps and explore how they work to keep your space comfortable while reducing your carbon footprint and energy costs. So, let’s get started!

What Are Air Source Heat Pumps?

Air source heat pumps are a modern type of low-carbon, renewable heating technology. They extract heat from the outside air and use it to heat buildings and water for domestic or commercial use. 

How Do Heat Pumps Work? 

Air source heat pumps work by pulling in air from outside and using it to heat a special refrigerant liquid. As it warms up, the liquid turns into a gas which is compressed to increase its temperature. This gas works to heat your property.

Once the gas cools, it becomes liquid again, allowing it to be re-used at the start of the next heating cycle. The whole process uses only a small amount of electricity, making it a fantastic renewable option. 

Will Air Source Pumps Work In The Cold?

Yes, air source heat pumps can work in cold weather. Even when the day cools down, there is still enough heat in the ground and air for the pumps to absorb and use. 

What Are The Benefits Of Air Source Pumps?

There are a wide variety of benefits to getting an air source heat pump for your property. Some of the key benefits include:

  • They are cheaper to install than other types of heat pumps (for example, ground source heat pumps)
  • They have lower running costs than other types of pumps
  • They can work in temperatures as low as -15°C
  • The external heat pump unit is compact & doesn’t take up too much space on your property
  • They help you to reduce your carbon footprint 

Overall, there are many reasons you might choose to install an air pump at your home or business. 

Are There Government Grants For Heat Pumps?

Yes, there are a range of government grants available to help you afford heat pumps for your property. Replacing gas boilers across the UK with clean energy alternatives is a part of the UK Government’s plans to help reach Net Zero for 2050, and as such, a range of grants and loans exist to help with the cost of a heat pump and its installation.

England and Wales

The ‘Boiler Upgrade Scheme’ can help you to afford a new air source heat pump for your property. The scheme provides homeowners with £5,000 to help them with the initial cost of upgrading from a gas or fossil fuel boiler to a low-carbon alternative.


In Scotland you can apply for a £7,500 grant from Home Energy Scotland. You can also get a £1,500 top-up if you live in a rural area.
