Frequently Asked Questions
about Air Source Heat Pumps

What is an Air Source Heat Pump?

In short, ASHPs work by transferring air from one place to another. Heat from the air is gathered up and taken into a loop of refrigerant fluid, followed by being transferred to a compressor, providing you with hot air.

The pump is extremely clever and will transfer all this heat through different pipes, whether this being multiple radiators throughout your home or underfloor heating.
The air source heat pump is not just for heating up your home either, during the warmer months your pump will grab onto heat in the air within your home and release it back outside, leaving you with cooler summer months and warmer winter nights.

What are the pros of using an Air Source Heat Pump?
  • Less space is required internally for an Air Source Heat Pump. Although external space is still required, if you find yourself limited to space inside, this could be an ideal solution for you.
  • No groundworks or external collector pipework is required, meaning an Air Source Heat Pump can be more affordable than a Ground Source Heat pump.
  • A cheaper alternative for heating your home and can be even cheaper with access to government grants.
  • An ASHP has an excellent life span.
  • It can be used for both heating and cooling of the home.
  • Great effective use of using natural energy to power your home.
What are the cons of using an Air Source Heat Pump?
  • For an ASHP to work effectively, you must first have an already well-insulated home. For example underfloor heating or well-insulated loft space and walls.
  • There can often be a small noise when using an ASHP.
Are grants available for installing the Air Source Heat Pump?

The Green Energy Grant enables you to receive payments for generating your own heat through the Renewable Heat Incentive. This scheme has been extended until March 2022, meaning that if you have your heat pump installed during this period, you could be eligible to receive payments for each unit installed for a period of time. These payments are calculated via the Renewable Heat Incentive tariffs.

How long will it take for my Air Source Heat Pump to be installed?

The ASHP is much easier to install than the Ground Source Heat Pump as, unlike the GSHP, no digging is required. As a result of this, the installation process is much simpler and often quicker.

What are the types of properties an ASHP is and isn't suitable for?

To begin with, your home must already be well insulated. Air Source Heat Pumps typically have a lower heat supply than boilers, therefore an already well-insulated home will work best.

Smaller properties are ideal for this pump, however, space must be available for the external unit. If you live within a larger property, more external units can be installed, however, this will have an overall effect on the costs.

Comparison of traditional heating methods

Compared to a gas or electric heating system, an air source heat pump is a renewable alternative to heating your home; lessening your carbon footprint and allowing you to save money on your utility bills.
