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
