Typical HSPF ratings range from 7 to 10 for air source heat pumps and 8 to 11 for geothermal (ground-source) heat pumps. The minimum HSPF for Energy Star-certified heat pumps is 8.2. What is HSPF2? HSPF2 is the new metric adopted by the DOE in 2023 to represent real-world efficiency and performance of heat pumps.

HSPF stands for ‘Heating Seasonal Performance Factor’. It is a metric that determines the overall energy-efficiency of heating devices in much the same way as the SEER rating for cooling devices. It gives you an idea of how significantly will running such …

Here is how we can calculate both HSPF and HSPF2 rating for the same heat pump: HSPF Rating = 10,000 BTU / 1,000W = 10 HSPF. HSPF2 Rating = 8,500 BTU / 1,000W = 8.5 HSPF2. What is the reason for this sudden difference between HSPF and HSPF2? These energy efficiency rating are very useful when you want to determine which heat pump to buy.

2024年9月29日 · According to Mark Woodruff, Senior Product Manager of Ducted Outdoor Products for Trane Residential and American Standard Heating & Air Conditioning, HSPF is “a ratio of the heat output to electricity use over an average heating season, and the higher the HSPF the greater the energy efficiency.”

HSPF, or Heating Seasonal Performance Factor, measures how efficiently a heat pump can heat your home during the cold weather months. The Department of Energy (DOE) has recently refined the testing procedure for determining HSPF, resulting in the creation of HSPF2, a more accurate scale to measure heat pump efficiency.

2022年1月5日 · HSPF is a metric used in the evaluation of air source heat pumps when in heating mode. It stands for Heating Seasonal Performance Factor and it measures how well your heat pump will perform during the heating seasons. HSPF measures heat output over a heating season to the electricity used.

With an HSPF savings calculator, you can determine your average energy cost each year to come up with the approximate annual savings generated by the more efficient device. Consider the HSPF rating chart below: The above example uses an electric rate of $0.121 per kWh and a lifetime usage of just over nine years.

You can use this heat pump sizing chart or consult the heat pump size calculator here to roughly estimate the size of the heat pump you need. Once you know the size of heat pump you need, you should focus on energy efficiency; that means SEER and HSPF ratings.

2022年9月28日 · HSPF stands for Heating Seasonal Performance Factor and is calculated by dividing the total heating output of the season (BTUs/hour) by the total energy consumption during that time (Watt/hour). The higher the HSPF rating, the more energy efficient a …

2023年8月5日 · HSPF2 is the Heating Seasonal Performance Factor, version 2. The new heat pump heating efficiency rating replaced the original HSPF rating that expired on December 31, 2022. The Department of Energy (DOE) put this new metric in place in order to make HVAC testing procedures more accurate to real-life conditions. What is HSPF2?
