WULFE® heat pumps
energy efficient water heater

WULFE® hot water heaters use heat pump technology that offers up to 71%* energy savings compared to conventional water heaters. Produced by the world's largest appliance manufacturer, they have been proven in temperatures as low as -7°C.

The system has been certified by the Australian Government Clean Energy Regulator, which allows customers to claim government rebates and reduces their investment.

The WULFE® HP series has an advanced control system that is easy to use and can be programmed to maximise the use of solar power systems while ensuring a constant supply of hot water. It also features an automatic sanitisation function to keep your family safe from waterborne bacteria.

With its quiet operation, smart controls, UV protection, and government rebates, WULFE® is the perfect choice for an energy-efficient home.
