I would like to model a SHW system for a multifamily apartment building under two different setups:

1. A central system with a gas boiler and central storage tank, and,
2. In unit gas tank water heaters for each apartment.

As part of this I would like to model the losses from the piping and tanks for each system.

Is there any easier way to do this than by using the WaterHeater:Mixed object and calculating the On/Off Cycle Loss coefficient to Ambient Temperature externally in an excel sheet with some assumptions about piping/tank length, diameter, etc.

Is the WaterHeater:Mixed object currently the only option for ambient temperature losses?
