SCOP Calculation
Seasonal Performance
Heat pump COP varies throughout the year based on outdoor temperature conditions.
Understanding SCOP
COP vs SCOP: COP is a single measurement. SCOP averages across entire season.
Realistic Picture: SCOP predicts annual costs better than COP alone
Calculation: SCOP = (Winter×3 + Spring/Fall×6 + Summer×3) ÷ 12
Example: Winter 2.8 + Spring 3.8 + Summer 4.8 = SCOP 3.73
Example: SCOP Calculation
1
Winter COP (3 months): 2.8
2
Spring/Fall COP (6 months): 3.8
3
Summer COP (3 months): 4.8
4
SCOP = (2.8×3 + 3.8×6 + 4.8×3) ÷ 12 = 3.73
