Note

Displayed temperature regime

The temperature regime which is displayed on the pipes in Hysopt, is the regime of the aggregated flow.

This is not the return temperature of one of the individual parts!

Aggregation methods

Design flow rates for heating prioritised by DHW, heating not prioritised by DHW, and DHW in the common pipe sections are calculated separately.
To calculate the installation components (pipe sections, primary pump, storage tank, boiler, ...) it is however necessary to have one design flow rate and one thermal power. Therefor Hysopt has developed two methods to aggregate the flow rates and thermal power in the common pipes as explained below.

...

  1. Maximum of central heating and diversified DHW flow

  2. Weighted average of central heating and total DHW flow
