***During operation, a DHW temperature below 60 °C does not accord to DVGW 551 (German association for gas and water). The compliance with water

quality standards must be observed.

70 °C / 60 °C / 10 °C flow temperature 70 °C / Hot water temperature 60 °C / Cold water temperature 10 °C

Basis of calculation is the DHW demand of max. 12 l/min and the simultaneity factor according to DIN 4708

Dimensioning Friwa

The performance of Friwa primarily depends on the temperature in the buffer tank, which delivers the energy to heat up the DHW.

The demand of hot water depends on the flow and on the number of consumers. In larger apartment buildings, a statistic distribution of withdrawals can be

detected. The following table shows a basic overview of the application range of Friwa module variants.
