- 75 % of the energy is taken from the environment i.e. from air and transferred to the heat pump.
- 25 % of the energy is sourced from regular electricity. This is used to operate the heat pump, not to heat the water.
- The energy from air is transferred to the refrigerant inside the heat pumps evaporator. This causes the temperature of the refrigerant to rise and change state from liquid to gas.
- The refrigerant gas then compressed, using an electrically driven compressor, reducing its volume but causing its temperature to rise significantly.
- A heat exchanger (Condenser) then extracts the heat energy from the hot refrigerant to heat water.
- After giving up its heat energy, the refrigerant turn back into a liquid and is able to absorb energy from the environment, allowing the cycle to begin again.
The efficiency of heat hump is measured in terms of “coefficient of performance” (COP). Approximately 75 % of the energy needed for heating comes from the ambient. This means for every 1KWh of electrical input used to power the heat pump, up to 4 KWh of heat energy is simultaneously produced, resulting in phenomenal COP.
