Dux D2FHG4HW0C Airo-Heat 250Litre Heat Pump

If your home doesn’t offer suitable roof space and orientation for installing solar collectors, Dux D2FHG4HW0C Airo-Heat 250Litre Heat Pump is the next best choice in environmentally friendly water heaters, without the need for solar panels.

Working like a refrigerator but in reverse, it takes air in from outside the tank and uses it to heat water. Its patented in-tank heating coil ensures direct heat transfer, eliminating exposure to heat loss issues often associated with other styles of heat pump.

  • Single piece design allows for faster installation
  • Composite condensation tray is designed for rapid drainage in high rainfall areas
  • Dual anodes provide greater protection against tank corrosion
  • Patented in-tank heating coil to improve heat transfer
  • Improved thermal efficiency minimises heat loss due to a fully insulated storage tank and a robust refrigeration system
  • Water connections on both sides of tank provide easy installation
  • Eligible for Small-scale technology certificates
  • 5-year tank warranty, 2-year refrigerant components, 1-year full parts and labour*
