[Equest-users] Heat Pump Efficiencies

[Carol Gardner]

I also found some formulas when tooling around in the archives the other day
and could love to get comments, if any about their utlity:

EIR=(1/EER-0.012167)/((1/3.413)+0.012167)
and
EIR=((1/SEER*0.778+1.4)-0.012167)/((1/3.413)+0.012167)

Anyone remember these that knows the source and utility? Is there one for
HSPF?
