Heat pump installers in Dunedin
Dunedin's housing stock is, on average, the oldest in NZ — uninsulated villas are common. Sizing a heat pump for a leaky pre-1940 villa is a different exercise to sizing one for a modern build, and Warmer Kiwi Homes insulation funding usually applies first.
Local climate notes
DWG-03 / DUNEDIN
Cold, damp winters (lows 0–4°C). Many homes are pre-1940 villas with minimal insulation — heat loss is the dominant variable, not heat pump kW.
