The heat pump: how does it work?
A heat pump is a thermodynamic machine that takes heat from the outside (air and ground) to transfer it using a compressor to heat or cool the home, and produce hot water.
The heat pump only consumes the electricity required to operate the compressor and its accessories. This is why its requirements are 3 to 4 times lower than the energy its recovers.
The Coefficient of Performance (COP) measures the ratio between the energy supplied and the energy used: for instance, a heat pump with a COP of 3 will consume 1 kWh of electricity and supply 3 kWh for the heating system.
Heat pumps enable savings of up to 70% on a heating bill. In comparison with a fuel oil boiler, heat pumps can reduce CO2 emissions by more than 70%.
What is thermodynamism?
Thermodynamism is a closed and waterproofed circuit in which a refrigerant fluid in its liquid or gaseous state circulates according to the elements through which it has to flow.

Operation principle of the heat pump water heater
Tha ambiant air* is pulled in by the fan (1), heats the gaseous refrigerant fluid in the evaporator (2). The fluid then goes into the compressor (3) where its temperature increases further. In the condenser (4), the fluid transfers its heat to the water in the tank. Its cools down and transfers from gaseous to a liquid state. The expansion valve (5) initiates the fluid's transfer to a gaseous state and enables the fluid to begin a new cycle in the evaporator. The electric heating (6) turns on only when required.
