[Equest-users] Ground source heat pump supplemented by boiler

[Frink, Brandon]

Hello,
I am trying to model a building with ground source heat pumps in eQuest. The project is in Maine so a boiler is required to supplement the ground loop in the winter. I have set up a water loop HP type circulation loop and attached a ground loop heat exchanger and a boiler. When I run the program an error occurs saying that it is not allowed to use a ground loop heat exchanger and boiler in the same loop. Is there some type of work around to approximate a water loop HP that uses the ground loop heat exchanger as a heat sink or source when it is above a certain outside air temperature and switches to the boiler as a heat source below a certain temperature?
Thanks,
