What does HSPF measure?
The HSPF is a heat pump’s heating version of SEER* or Seasonal Energy Efficiency Ratio. HSPF measures heat pump efficiency in heating mode SEER measures heat pump efficiency in cooling mode.
How is HSPF calculated?
HSPF ratings are calculated by dividing the total heating output during the fall and winter months (measured in BTUs or British Thermal Units) by the total watt-hours of energy consumed during these months (measured in kWh or kilowatt-hours).
How much does a heat pump unit weigh?
Regardless of your need to know how much a heat pump weighs, you can see from the data below that a residential heat pump is going to weigh anywhere from about 135 to 280 pounds depending on the BTU’s.
What is heat pump efficiency measured by?
When in heating mode, a heat pump’s efficiency is measured as HSPF, which stands for “heating seasonal performance factor.” It is measured in an almost identical way to SEER: the ratio of heat provided in BTUs to the energy consumed in watt-hours, as measured over a season.
What is HSPF and COP?
Heating seasonal performance factor (HSPF) and coefficient of performance (COP) are both ways you can measure the efficiency of a heat pump. HSPF compares the output in British thermal units or BTU to the input in watt-hours.
What temperature is HSPF calculated?
In the standard HSPF calculation procedure, the capacity and power input curves are generated using measured data from three points. These points are at outdoor temperatures of 47 F (the high temperature test), 17 F (the low temperature test), and 35 F (the frost accumulation test).
What is SEER and HSPF?
The Seasonal Energy Efficiency Ratio (SEER) measures cooling efficiency over the cooling season, while the Heating Seasonal Performance Factor (HSPF) measures heating efficiency over the heating season.
How much does a 3 ton HVAC unit weigh?
between 200 and 215 pounds
A 3-ton unit will be a little bit larger than a 4-ton unit. The normal weight for a 3-ton unit is between 200 and 215 pounds, sometimes less, but keep in mind that the weight also depends on the brand that you buy and the materials that the manufacturers use to build the unit.
How much does a 2 ton heat pump weigh?

What is the difference between a COP and an HSPF?
HSPF compares the output in British thermal units or BTU to the input in watt-hours. You can find the COP, by contrast, by dividing the amount of heat extracted from the cold reservoir by the amount of work it took to transport this heat.
How do you calculate heat pump kW?
It uses the formula BTU/EER = watts, which the calculator then divides by 1,000 to give you kilowatts. For example, if you have a 24,000 BTU AC and it’s EER rating is 8, our calculator gives an answer of 3kW. If its EER rating is 10, then it uses only 2.4 kW of energy per hour.
