I´m modelling a hot water plant loop with several Water use connections.

Heat source is district heating, var. speed pump is in supply side. Set Point Manager is Scheduled.

When I run the simulation everything is fine, requested mass flows are met in each node, as well as setpoint temperatures.

But when i add indoor Pipes in front of the water use connections, to simulate the heat loss of circulating the hot water, there is no mass flow at all through them, even though the requested mass flow is the same as before.

Does anyone have an idea how i can model the plant loop with water use connections and indoor pipes for calculating the heat loss? I couldn´t find any special Requests for Pipe:Indoor in the documentation.

Mass Flow is there as it should be until node 229. In every other node before the pipes is no mass flow at all, but in inlet node of supply side is the mass flow back agian.
