Going to a Heat-Pump System? Weigh the HSPF Ratings

Posted on: October 6, 2011

Since the climate in Charlotte, North Carolina requires only moderate heating and cooling, a heat pump is an energy-efficient way to keep your home temperature the way you want it. However, not all heat pumps are created equal. You can figure out which heat-pump system is your best choice by weighing the HSPF ratings.

Why are HSPF ratings so important?

HSPF ratings tell you how efficient a heat pump is. A more efficient heat pump will result in less energy use and increased energy savings over the life of the system compared to a less efficient one.

What does HSPF stand for?

HSPF is short for Heating Seasonal Performance Factor.

What do HSPF ratings measure?

HSPF ratings measure the heating efficiency of a heat pump system by dividing the amount of heating required during a heating season with the amount of the total electrical energy used. Ratings are based on the following factors:

  • The efficiency of the heat pump system’s compressor
  • The efficiency of the electric-resistance elements of the heat pump system
  • The number of BTUs (British thermal units) of heat that the heat pump system moves for every watt-hour of electrical energy used

What is considered a good HSPF rating?

The higher the HSPF rating, the more efficient a heat pump is. Generally, you should look for heat pumps with a HSPF rating of between 8 and 10. Heat-pumps with a rating of at least 7.7 HSPF are awarded the Energy Star label by the U.S. EPA. However, for a heat pump to have the Energy Star label, it must also have a SEER rating of 12 or greater. SEER, short for Seasonal Energy Efficiency Ratio, measures the cooling efficiency of a heat pump.

How do I find the HSPF rating of a heat pump system?

All heat pump systems sold in the U.S. have an EnergyGuide Label. Check a product’s label to find its HSPF rating as well as its cooling efficiency performance rating.
