[Equest-users] How to model HP with supplemental heat?

[Syed, Fareed]

I am facing the same issue. Electrical supplemental heat is working but not gas.

Can you please elaborate on post-processing item....how do you do that?


Thanks,

Fareed

I have found problems with the supplemental heat for heat pumps for all supplemental heat types excepting electricity.  In the past I have post-processed hourly results in order to get an approximation of gas supplemental heat use.

Hello All,

I am trying to model heat pump with supplemental heat supported by a gas fired boiler.

I connected hot water loop to the Supplemental Heat under Systems-->Heating-->Supp Heat/Defrost but the boiler is not turning on. The start point for the HW loop to support the HP was modeled at 45F.

Can anyone please advice on how to model this heat pump with hot water coil?
