Introduction

During the compute design flows action, we propagate power, design flow and temperature regimes.

When two branches come together, we first propagate propagate the individual parts :

1. domestic hot water (DHW)

2. heating prioritised by DHW (e.g. when HIU’s are applied)

3. heating not prioritised by DHW (e.g. when electric heaters are applied)

On top of these propagated individual parts, we will apply aggragation, as explained in Step 6 : aggregation of the DHW flow/power with the CH flow/power
