Le powers of heat pumps are varied and meet the needs from small to large systems, in proportion to the power of the machine, change the power consumption.
The correct choice of a machine takes account of two main elements: heating requirements building to be heated (the heat demand is the highest demand for heat when the outside temperature is reached minimum design) and the maximum temperature for the plant (Underfloor heating, fan coils, radiators, etc.)..
For example, considering a building in Rome with 10 kW / h of heat demand, in which it is installed a radiant floor dimensioned to operate at maximum 35 ° C flow, the heat pump will consume about 2,8 kW / h .
In principle, by dividing the heat requirement (eg 10kW / h) by the COP of the machine (about 3,5 for radiant systems), an estimate of the instantaneous consumption of the heat pump can be obtained.
If you want to calculate the cost of running a heat pump, using the computer on-line consumption of the heat pump.
