Air-to-water heat pump
One efficient system supplies domestic hot water and the home's central heating.

High-end new build · Wānaka
Plumbing, heating and energy designed as one reliable, low-impact system.
The brief
Working alongside Three Sixty Architecture, Optum designed the home's plumbing, heating and energy systems as part of the architecture from the outset.
The total package covered plumbing, drainage, gasfitting and heating, with every component selected to be efficient, reliable, inexpensive to run and maintain, and low in environmental impact.
Generation, storage, heating and hot water work together instead of competing for energy.
One efficient system supplies domestic hot water and the home's central heating.
On-site generation supports the heat pump as well as the wider household electrical load.
A dual-element thermal store provides a dependable buffer for heating and hot water.
Heatmiser controls allow even low-temperature warmth to be managed room by room.
