Heat pump types
Air source. Confirm the model and complete system scope.

Before you appoint an installer
Check the exact contracting business and its current certification for the proposed technology. Ask for a room-by-room heat-loss calculation, system design, an itemised quote and written aftercare terms. Compare more than one quotation.
