[Equest-users] How to get GLHP Supp. HW Heat to Register on Energy Summary

[Kathryn Kerns]

Everyone, I am trying to create a model for a hybrid GLHP system where
the ground loop system cools and a boiler system heats. I started in the
Wizard by modeling a GLHP system with baseboard hot water heaters. So
with all of the elements present, I switched over to DE and limited the
size of baseboard heat down to -10 Btu/h per zone, and added a hot water
supplemental heating section to each GLHP. The supplemental hot water
coil has a capacity of -30,000 btu/h per zone. I think I also allowed
the supplemental heat to start below 70 F and turned off the heat pump
heating below 70 F. At least that is what I interpret the 2 variables in
the heat supplemental heating screen to be. I think this system working
and heating is taking place because I see supplemental heating
consumption showing up in the detailed heat pump reports. However, I
don't see any supplemental heating showing up in the energy consumption
graph, and I think there should be some, correct?

 

If someone has some time, can anybody figure out why the supplemental
heat is not showing up on the energy consumption graph?

 

I have attached the starting file and input file.

 

Thanks.
