Benefits of the HSPF Energy Calculator
How efficient thinking adds up to big savings.
Heating and cooling can account for more than half of your home’s total utility bill.* So when looking for ways to cut your energy costs, be sure to think about a high-efficiency system. High-efficiency systems are easily identified by reading the yellow-and-black Energy Guide label found on the equipment.

Frequently Asked Questions
HSPF, or Heating Seasonal Performance Factor, is incredibly important when it comes to assessing the energy efficiency of your heating system, particularly heat pumps. It measures the ratio of heat output to electricity consumption over an entire heating season. The higher the HSPF rating, the more efficient the heat pump is, and the more you can save on your energy bills. Investing in a heat pump with a high HSPF rating can lead to substantial long-term energy savings, making it a critical factor in making informed heating system decisions.
The calculation of HSPF involves determining the total heat output of the heat pump during the heating season (in British Thermal Units - BTUs) and dividing it by the total electricity consumed over the same period (in watt-hours). To be more specific, the formula for calculating HSPF is:
HSPF = (Total heat output in BTUs) / (Total electricity consumed in watt-hours)
It's worth noting that the HSPF calculation takes into account the seasonal variations in weather and considers the heating demands during milder and harsher climates. This way, you get a comprehensive understanding of the heat pump's efficiency across various conditions.
HSPF, Heating Seasonal Performance Factor, is a metric used to determine the energy efficiency of heat pumps. It's similar to SEER (Seasonal Energy Efficiency Ratio) for cooling systems but specifically tailored to assess the heating performance of heat pumps during the colder months. HSPF measures how effectively a heat pump can convert electricity into heating power, taking into account both the electricity consumption and the heat output over an entire heating season. A higher HSPF rating indicates that the heat pump can produce more heat while consuming less electricity, making it more energy-efficient and cost-effective in the long run.

HSPF is calculated based on the heat pump's performance during the entire heating season, which typically spans from fall to spring when outdoor temperatures range from 10 to 60 degrees Fahrenheit (-12 to 15.5 degrees Celsius). This range allows for a comprehensive evaluation of the heat pump's efficiency under different weather conditions, from milder autumn days to colder winter nights. The HSPF calculation ensures that the heat pump's energy efficiency is assessed across the full spectrum of temperatures it is likely to encounter during the heating season.
The Heating Seasonal Performance Factor (HSPF) is expressed in a unitless value. Unlike other energy efficiency metrics that have specific units, such as SEER in BTU per watt-hour, HSPF is a ratio of heat output (BTUs) to electricity consumption (watt-hours) and, therefore, does not have any units. The unitless nature of HSPF simplifies its interpretation, making it easy for homeowners to compare the energy efficiency of different heat pumps and make informed decisions about their heating systems.
