Heating* — Heat Loss KW x Heating Degree Days x “C” x Cost Per KWH = Operating Cost
Outdoor Design Temperature Difference
* The above formula is for electric resistance heating only. Power consumption using the Zoneline Heat Pumps should be adjusted by Seasonal Performance Factor (SPF).
The local power supplier should be consulted for recommended value of “C.” This factor will vary between 17 and 24.
Cooling — Calculated Heat Gain (BTUH) x = Unit Cooling Watts x Cooling Hours x Cost per KWH = Operating Cost
Installed unit capacity (BTUH)
1000 Watts/KW
