I am modeling a multifamily building retrofit. Existing building has a central gas water heater, retrofit has individual HPWH in each unit. I keep getting this error when I try to run the model. I've tried different HPWH options and different distribution options and always get the same error. Has anyone seen this before? Is it not possible to switch from a central system to a distributed system?

The "Water Heating > Distribution" category is for the hot water pipes within each unit, so you need to pick an option that isn't None if you have a water heater (both individual and central).

The "Water Heating > Central Distribution" category is for the hot water pipes between units, so you only need to pick an option that isn't None if you have a central water heater.
