I'm modeling a Water Heater:Heat Pump in Openstudio and am having trouble with the attached tank doing ALL of the water heating. I've tried a couple of things like adjusting the capacity and volume of the tank down to 1, but that just seems to remove that load completely. I've also tried to increase the capacity of the DX Coil in the HPWH, but that had no effect. Any ideas??

Solved my own problem!

Had to raise the compressor setpoint temperature higher than the tank setpoint.
