2. TECHNICAL FEATURES
2.1 Operating principle
The heat pump water heater does not directly heat water using electrical energy, but makes a more rational use of the
latter to obtain the same result in a more efficient
manner, namely by consuming approx. 2/3 less water.
The efficiency of a heat pump cycle is measured by the Coefficient of Performance (COP), i.e. the ratio between the
energy supplied to the appliance (in this case, the heat transferred to the water to be
heated) and the electrical energy
used (by the compressor and the appliance's auxiliary devices). The COP varies according to the type of heat pump
and to its relative conditions of operation.
For example, a COP value equal to 3 indicates that for every 1
electrical energy used, the heat pump supplies 3 kWh of heat to the medium to be heated, of which 2 kWh are
extracted from the free source.
