Glossary: HSPF Rating - Energy Efficiency Terms
Learn about HSPF Rating and how it relates to energy efficiency and rebates in Ontario.
HSPF Rating
Definition: Heating Seasonal Performance Factor - measures the heating efficiency of heat pumps during the heating season.
HSPF ratings typically range from 7 to 13, with higher numbers indicating better heating efficiency. Cold climate heat pumps often have HSPF ratings of 10 or higher.
Understanding HSPF Ratings
HSPF measures how efficiently a heat pump heats your home over an entire heating season, including defrost cycles and varying outdoor temperatures.
HSPF Rating Categories
- 7-8 HSPF: Standard efficiency
- 8-9 HSPF: High efficiency
- 9-10 HSPF: Very high efficiency
- 10+ HSPF: Ultra-high efficiency (cold climate models)
HSPF vs SEER
While SEER measures cooling efficiency, HSPF measures heating efficiency. Both are important for Ontario homeowners who need year-round comfort.
