Homeowner guideAlexandra is a Central Otago town, and its heat pump installers lean on the big brands and on people who also do refrigeration and electrical work. Six businesses serve the area: four work from Alexandra, one from Cromwell and one from Ranfurly. The Central Otago District Council is the building consent authority for the town.
Inland and southern New Zealand towns see colder winters than the coast, and frost can occur anywhere on clear, still nights. That gives heating work in Central Otago a different feel from the north of the country, where the same units are mostly used to cool a room.

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.
