Efficient heating, hot water and cooling.

Three families of proven systems — each designed around your real demand and site, then installed and maintained to keep performing.

Solar thermal

Solar Water Heating

Hot water from the sun with a backup that never leaves you cold.

Explore Solar Water Heating

Indirect solar water heaters that harvest the sun for the bulk of your hot water and quietly top up on electricity only when the weather won't cooperate. Because they are indirect systems, the collector fluid and your domestic water never mix so they work with any water quality and hold high pressure.

  • Cut your water-heating electricity bill dramatically
  • Continuous hot water, backed up for cloudy days
  • Works on any water quality — borehole, hard or municipal
  • Split option hides the tank indoors for a clean roofline

Air-source

Heat Pumps

Up to three-quarters less electricity for the same hot water.

Explore Heat Pumps

Air-source heat pumps move heat instead of making it, delivering several units of heat for every unit of electricity they draw. For hot water and heating, they are the most efficient electric option available and they keep working through the night and the cold.

  • 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
  • Quiet operation, suitable for tight installations
  • By-product cool air can be ducted to a store, server room or bathroom

Solar cooling

Hybrid Solar Air Conditioning

Cool your space on sunshine by day, the grid by night.

Explore Hybrid Solar Air Conditioning

Hybrid solar air conditioners run directly off solar panels during the day and seamlessly switch between solar, grid, or both. No additional batteries, separate inverter or complex wiring required. In good sun they can cut cooling electricity by 60–90%.

  • 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
  • Smart-app control with solar and grid power metering
