The health risks of cooking and heating with gas

How heat pump water
heaters work
1
An air-source heat pump transfers heat from the outside air to heat your water, typically to about 55 degrees
2
A refrigerant gas is compressed to raise its pressure and temperature.
3
The heat is transferred from the hot, pressurised refrigerant to the water in the storage tank.
4
The refrigerant is sent back to the compressor and the process restarts until the temperature set point is reached.
OUR STORY
We're on a mission
Hot Water Savings was borne out of the frustration over high energy bills and underutilisation of quality technology for water heating. At present, only 5% of Australians use heat pump water heaters. We believe this is due partly to uncertainty and some outdated myths. Our vision is to bring easy to understand, data-driven recommendations to every Australian household so we can all reduce our utility bills and greenhouse gas emissions.
