[Equest-users] Tank less DWH

[Morteza Kasmai via Equest-users]

Hello, everyone

I am trying to model a new DWH (Intelli-hot system Gen-II-iQ1501) for a
mid-rise residential building. This is a high-output, on-demand water
heater, which eliminates storage tank, standby losses, and mixing valves.
Per the manufacturers and the project’s engineer notes, expected savings on
hot water for this type of WH compare to a regular storage tank WH is 30%
to 40%. I am wondering what type of WH should I select for the Baseline
Case in order to comply with ASHRAE/LEED energy modeling protocol.


Your thoughts and suggestions would be highly appreciated,
Morteza
