No on-site fuel storage needed for air source systems
The basics
What heat pumps actually does
A heat pump moves heat from the air or ground into your home. It works differently to a gas boiler and usually runs at lower temperatures over longer periods.
This is likely to suit you if…
- Your home is reasonably well insulated
- You have outdoor space for a unit or land for ground loops
- You are off the gas grid or replacing an old fossil-fuel system
- You want lower-carbon heating and hot water
Your options
Types of work an installer may recommend
Which option suits you depends on your property's construction, age and condition. A survey confirms what is possible.
Air source heat pump
An outdoor unit that draws heat from the air.
Ground source heat pump
Pipework in the ground, suited to properties with land.
Hybrid systems
A heat pump paired with an existing boiler.
Design is everything with a heat pump
Performance comes from a proper heat-loss calculation, correctly sized emitters and a sensible flow temperature. Always ask to see the design before you commit.
