For your home

Comfort that costs less to run.

Endless hot water and efficient cooling for houses and apartments — designed around how you actually live, installed cleanly, and looked after for the long run.

What we install at home

Three ways to save

Solar Water Heating

  • Cut your water-heating electricity bill dramatically
  • Continuous hot water, backed up for cloudy days
  • Works on any water quality — borehole, hard or municipal

Heat Pumps

  • Around 70% less electricity than a standard electric water heater
  • Hot water day and night, independent of sunshine
  • All-in-one units with the tank and pump integrated

Hybrid Solar Air Conditioning

  • 60–90% less cooling electricity in good sunshine
  • No battery bank and no extra inverter to buy or maintain
  • Cool rooms during the day even when the grid is down
