Heat Pump Hot Water Systems

Midea Heat Pump Hot Water Systems extract warmth from the surrounding air, making them efficient for both energy and spatial requirements. Similar to a reverse cycle air-conditioner, heat pumps use a refrigerant gas to transfer heat to the water storage tank.

Did you know?


According to Sustainability Victoria, hot water contributes 16% to the energy costs of an average household.

Heat pumps are an ideal low-cost hot water solution in a wide variety of circumstances:

  • An existing electric storage hot water system requires replacing
  • Unsuitable roof space for solar collectors
  • Reticulated gas is not available (i.e. regional areas)
  • Excess power from solar panels is being fed into the grid rather than being utilised

How it works

  1. A fan draws warm air into the top of the system and across the evaporator
  2. The evaporator turns a liquid refrigerant into a gas
  3. The compressor pressurises the refrigerant into a hot gas
  4. The hot gas inside the condenser coil heats the water inside the coil-wrapped tank
  5. The refrigerant reverts back to a liquid after heating the water

Built for efficiency

Despite resembling a traditional hot water storage unit, heat pumps require much less energy because the only elements that require electricity are the fan and compressor.

Figures from Sustainability Victoria (see below) illustrate that heat pumps are comparable to electric boosted solar hot water systems for operating costs, and out-perform traditional hot water storage systems.
