Air source heat pumps use fresh air and a little bit of electricity to heat your home and hot water. And last time we checked, fresh air was free. That’s why they’re 4X more efficient than a gas boiler. And why they have the power to slash your energy bills.

Air source heat pumps aren’t just efficient, they’re in a league of their own. Operating at over 400% efficiency, they generate four times the heat for every unit of electricity used.
Compare that to gas boilers, which waste at least 10% of their energy through flue gases, leaving them at just 85%-90% efficiency. Even the best modern condensing boilers can’t get past 99%, making them four times less efficient than a heat pump.
While electricity costs more than gas, the supercharged efficiency of air source heat pumps means lower overall running costs. And, with Aira, you can upgrade to an air source heat pump for as little as £6,729.
Aira makes the switch to a clean energy heat pump accessible and affordable with our monthly payment options, 15-Year Aira Guarantee and energy bill savings from day one.
