Air source heat pumps are the most flexible option and suitable for most property types, including terraced houses as they don’t require a large amount of outdoor space.
If you are opting for a ground source heat pump, you will need sufficient garden space for either a borehole or ground array to be installed. Equally, water source heat pumps mean your home needs to be located within a certain distance of a body of water such as a lake, stream, or pond.

Although underfloor heating works well with a heat pump, it is not a requirement. With underfloor heating, the heat pump can operate at a low flow temperature thanks to a large transfer area.
The same applies to radiators, however, you may need to upgrade them to a bigger output. This is because heat pumps operate more efficiently at a lower temperature. Your Vaillant heat pump installer will support you by choosing the best option for you and your property .
Heat pumps can be more expensive to install compared to traditional gas boilers, however, there is government support available to support you with the initial upfront cost.
The Boiler Upgrade Scheme (BUS) provides a grant of up to £7,500 for air source and ground source heat pumps (water source heat pumps are included in the ground source criteria). Available to homeowners in England and Wales, your installer will apply for BUS on your behalf and deduct the voucher from your final bill.
If you live in Scotland, there is alternative funding available through the Home Energy Scotland (HES) grant which also offers up to £7,500 off the cost of installation. If you live in a more remote area, homeowners may be eligible for the rural uplift £9,000.
