Air Source Heat Pump Technology

Air Source Heat Pumps (ASHP) extract energy from the air outdoors and convert it into heat, enabling you to heat your home and water without the use of fossil fuels, even in the depths of a UK winter.


Similarly to how your fridge works, only in reverse, ASHPs use a combination of refrigerants, an evaporator, a compressor and a condenser to convert energy from the air into renewable heat for your property.


Heat pumps do use a small amount of electricity to run, but they output up to 4 times that amount of energy in the form of free renewable heat, making them a 300-400% efficient heating solution.

Renewable Heat Incentive (RHI)

By installing an Air Source Heat Pump, you will likely qualify for the Government’s Renewable Heat Incentive. The Government incentivises renewable heating systems to encourage people to choose a green heating option over a polluting, fossil fuel system. Our free quotations will provide you with a detailed breakdown of what you might expect to receive from the RHI, which could be up to £12,710 over 7 years. Find out more about the RHI.
