I ran some models comparing a building with Gas_WaterHeater vs HeatPump_WaterHeater. I expected a difference mainly in the Water Systems energy use. However I also notice the change in SHW also impacting space heating and cooling energy use. I’d assume that it shouldn’t affect space heating/cooling if I set the loss_coeff to 0. Is there any information on what other factors go into the SHW setup and how it may impact space heating/cooling?
