Homeowner guideCambridge sits on a short run of towns in the Waikato, and the heat pump installers who work from it also serve Tīrau and Putāruru to the south, Te Awamutu to the west and Hamilton. Waipā District Council is the building consent authority for Cambridge itself. Several of the businesses are in Leamington, the part of Cambridge where Pratts Cambridge has its showroom on Albert Street and Sparky Direct is based.

As a rough guide, allow about 120 watts per square metre in a well-insulated room, 140 in an average one and 160 in an older, draughty one. A 30 m² lounge works out at about 4.2 kW with average insulation and 4.8 kW if it loses heat. Heat pumps come in set sizes, so both round up to a 5 kW unit. Use the calculator above for your room, then have an installer confirm it.
