To understand the concept of how an Enviroheat heat pump works, imagine your refrigerator / freezer working in reverse. While a refrigerator removes heat from within the closed box and expels that heat to the surrounding air, a heat pump takes the heat from surrounding air and transfers it to water in an enclosed tank.

Enviroheat heat pump technology makes the efficient use of heat in the surrounding air, even at temperatures as low as -7C. In fact the Enviroheat heat pump hot water system is so efficient that it can convert 1kW of electricity into over 4kW of heat.

  1. The fan draws in the air containing heat energy, across an evaporator

  2. The evaporator turns the liquid refrigerant into gas

  3. The Enviroheat compressor pressurises the refrigerant liquid into hot gas

  4. The hot gas inside the condenser coil heats the water inside the tank

  5. The refrigerant reverts back to a liquid after expansion & continues back to the evaporator for the process to start all over again
