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.
