I'm modeling a GSHP loop, with secondary loops for radiant heating and cooling. I'm using the water-to-water heat pump component to transfer heat from the GSHP loop to the secondary loops. Right now there is no flow in the radiant loops and I can't figure out why.
GSHP loop is set up like this, with the water-to-water heat pump on the demand side.
Radiant hot water loop is set up like this
I am really stuck on this. If anyone has any insights please let me know. Thank you!
