[Equest-users] Indirect Fired Domestic Hot Water Heaters

[Eddie Corwin]

I am curious to know how you (the community) have modeled indirect DHW heaters 
in the past. There are two methods that I know of, and have employed in the 
past. 

1. Model the DHW load as a process load on you boiler loop. When done this way, 
you get the actual DHW energy consumption because the boilers will be at the 
proper point on the efficiency curves. The down side is that you don't get the 
proper energy breakdown in the eQuest results summary. 

2. Model the DHW heater with the same curves as your boilers. When done this 
way, the results may be off because your boiler and DHW heater will be at 
different points on the efficiency curves, but you will have the proper 
breakdown in the summary.

Does anyone have a better solution for modeling an indirect fired domestic hot 
water heater?
