Retrofit to an existing geyser
In most cases the existing cylinder is retained. We fit the heat pump, route flow and return, install sensors and a timer, and keep the element as backup for peak demand.

Heat Pumps
Heat pumps move heat instead of generating it, typically delivering three to four units of heat per unit of electricity. For households and guest houses with heavy hot-water use, they are the fastest payback we install.
Sizing and siting
Sizing follows daily hot-water volume and recovery requirement. Siting needs free airflow and consideration for the condensate the unit produces, as well as noise relative to bedrooms and neighbours.
Commercial hot water
Guest houses, laundries and kitchens are sized on peak-hour draw-off with buffer storage, so hot water does not run out during service.
