You can also see how they could help save you money, reduce your carbon footprint, and why thousands in the UK are already making the switch.
Heat pumps in a nutshell.
Find out what a heat pump is, how they work and why they're better for the environment than older heating systems.
How you can benefit and save with an air source heat pump.
Air source heat pumps (ASHPs) are the latest in home energy tech, taking warmth from the outside air, or ground, and using it to heat your home or provide your hot water.
Heat pumps are typically 3 to 4 times more efficient than older heating systems so they can reduce your carbon footprint and your heating costs.
Find out more including the different types available, if they're right for you, what's involved in installation, and how much you could save if you switch to an air source heat pump.

Grants for heat pumps.
Did you know you could get a government grant to help make getting a heat pump more affordable?
Grants for heat pumps are easy and simple to apply for:
The Boiler Upgrade Scheme (BUS): In England and Wales.
The Home Energy Scotland grant: If you're in Scotland.
The Northern Ireland Sustainable Energy Programme: For Northern Island.
Find out if you're eligible, how you can apply, and whether you could claim a £7,500 (BUS) grant for an air source heat pump for your home.
How do heat pumps work?
Air source heat pumps might sound complicated but they're actually quite simple.
They take air outside your home and extract the heat from it to heat your home and provide your hot water. The process is called 'air pump heating' and the cycle works like this:
Absorb. The heat pump's outdoor unit soaks up heat from the air.
Boost. The heat is "boosted" to make it even warmer.
Transfer. This boosted warmth is sent to your home's heating system.
Repeat. The cycle continues all year round (yes even in winter).

Heat pumps vs boilers, find the right solution for you.
Choosing the right energy tech for your home is important.
And comparing air source heat pumps and boilers can be tricky.
To help you make an informed choice, we've weighed up all the key factors you need to consider. Whether it's reducing your heating costs, increasing energy efficiency, or lowering your carbon footprint - we can help find the right solution for you.
Ground source vs air source heat pumps.
Broadly speaking, there are two main types of heat pump.
Air source heat pumps (ASHPs) harness natural energy from the air outside to heat your home and provide you with hot water.
Ground source heat pumps (GSHPs) work in similar ways, harnessing natural energy from the ground.
To help you choose the right one for you, we've compared and explored their efficiency, installation costs, and suitability for different homes. Read more about ground source vs air source heat pumps.
