It’s The Age Of The Aquarian –  pay 65% less on your water heating


Aquarian hot water heat pumps are highly energy-efficient :

  • they move heat (traditional water heaters cost more because they generate heat)
  • around one-third of the power usage of a standard hot water cylinder
  •  much faster ROI (returns on your investment)
  •  energy from the ambient air temperature is used to heat water
  •  energy is stored in an insulated hot water cylinder – using the same technology as heat pump air conditioners -for energy efficiency even in low temperatures
  •  powered by electricity, either from the grid or your own solar or other energy source.
