Potenza [KW]
Output [KW]
Thermal output is given in both KW or kcal/h in terms of average
temperature difference between primary and secondary circuit, all
for a range of primary 3 m3/h.
For example, a 1000 liters ECOCOMBI 2 with a water flow of 3 m3/h
at 80 °C inlet and outlet at 70 °C, has on the storage of water an
average temperature of 60 °C, the mean difference of temperature
will be:
(80 +70) / 20-60 = 15 °C and therefore you can exchange up to
approximately 32 KW.
