THERMODYNAMIC CYCLE

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 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.
