TECHNICAL FEATURES

2.1

Operating principle

The electric hybrid water heater uses electrical energy rationally, achieving the same result as an electric water heater
much more efficiently. This is possible due to the heat pump unit which allows an electrical energy savings of
approximately 50% compared to an electrical water heater.
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 kWh of 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.
