What Are Heat Pumps and How Do They Work?

Could You Ditch Your Gas Boiler for Good?

Energy prices aren’t what they used to be and for many UK households, the question isn’t just “how do we save money?” but “is there a better way to heat our home altogether?” That’s where air source heat pumps come in.

What Exactly Does a Heat Pump Do?

An air source heat pump takes heat from the air outside and uses it to warm your home. It works a bit like a fridge in reverse. A refrigerant absorbs outdoor heat, which is then compressed and transferred indoors. This heat can be used for central heating, underfloor systems or hot water tanks. Even when it’s cold outside, the system can still draw in heat. And because it transfers rather than generates heat, it’s significantly more efficient than a boiler, often producing three times more heat than the electricity it consumes.

Is It Worth It?

Here’s what you stand to gain:

• Lower energy bills, particularly over the long term
• Less dependency on gas or oil
• A more sustainable way to heat your home
• Eligibility for support through schemes like the Boiler Upgrade Scheme
• Some models offer cooling as well, helpful in warmer months
