The local climate helps. Mount Gisborne records mean daily solar exposure of about 15.1 MJ/m², which is roughly 4.2 kWh/m² per day across the year.

In postcode 3437 there are more than 3,900 dwellings, most of them larger separate houses with three or four bedrooms, so hot water demand is steady – from kids’ baths to evening showers after a commute. Many properties already have solar PV, and we are seeing more homes match that with efficient hot water installation to make the most of daytime generation. Brands like Rheem, Rinnai and Chromagen are common choices for a solar hot water installation, while Sanden and other premium systems are popular for those chasing the best heat pump hot water system and the most efficient hot water system overall.
