Average Delta [°C]
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 PUFFER 1 T of 1000 liters Capacity with a water flow of 3 m 3/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 34 KW.
Output of the lower heat exchangers PUFFER 1 depending on the average DeltaT between primary and accumulation considering flow rate 3 m3/h.
