Because a fixed heat pump is connected to the supply by a licensed electrician, the paperwork matters. WorkSafe says electricians must issue a Certificate of Compliance for fixed wiring work, and you should keep it for insurance claims or a sale. The Electrical Workers Registration Board has a public register where you can check a licence by name or number. Auckland Council is the building consent authority for the area, and the installers here name Auckland, Riverhead, Waimauku and Helensville as the places they work. Helensville, Silverdale, Whangaparāoa and Warkworth have their own pages nearby.

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.
