Service hot water heating system

1 post / 0 new

Hi All,

In Table 7.8 (Performance for water heating equipment) Page 72 of
90.1-2010(ASHRAE) for electric water heater

it mentions EF as = (0.97-.0.00132V) where EF is energy factor.

But in equest input tab under DHW its asks for EIR . Is EIR=1/EF?

Also it says for electric heater > 12KW standby loss =20+35sqrt(V) in btu/hr

where can we enter this stand by loss in equest in DHW tab?

Regards
Sambhav
