Heating EIR = (1/(COP*3.413)-0.012167)/((1/3.413)-0.012167)
and
Heating EIR = (1/((HSPF*0.28+1.13)*3.413)-0.012167)/((1/3.413)-0.012167)
 
Hope this helps,

Subject: [Equest-users] Converting Heat Pump COP to EIR



Everyone, is there a relationship written down somewhere that removes fan energy from a heat pump COP value to develop a heating EIR?  Something like the DX cooling EER equation that removes fan energy from EIR  cooling values? It looks like the eQuest wizard is doing something like that when a heat pump heating COP is entered, but I am not sure what.
