How a Heat Pump Hot Water System Works
Unlike a resistive electric heater that converts electricity directly to heat, a heat pump moves heat — making it 3–4× more efficient.
Air Intake
The heat pump draws in ambient air from the surroundings — even in cool weather, air contains useful heat energy.
Heat Extraction
Refrigerant in the evaporator coil absorbs heat from the air, turning from liquid to gas in the process.
Compression
A compressor raises the refrigerant temperature significantly — the same principle used in reverse-cycle air conditioning.
Water Heating
The hot refrigerant transfers its heat to the water in the storage tank, then cools and returns to start the cycle again.
The Efficiency Advantage
A conventional electric storage system uses 1 kWh of electricity to produce 1 kWh of heat (COP = 1.0). A quality heat pump produces 3–4 kWh of heat per kWh of electricity (COP = 3.0–4.0+). For a typical Australian household, this translates to annual hot water bill savings of $400–$1,200 compared to electric storage — with no change to comfort or convenience.
