[EnergyPlus_Support] Re: Central Heat Production vs terminal units

["anarui.oliveira" <anarui.oliveira@xxxxxxxxx>]

In Water Heaters group:

- Water Heater:Mixed
+
- Heat Pump:Water Heater
   - which in turn requires the definition of:
     - Coil:DX:HeatPumpWaterHeater
     - Fan:Simple:OnOff

You might want to check the Engineering Reference (pages 774, 779).
