What does HSPF mean?
Heating Seasonal Performance Factor
Heating Seasonal Performance Factor (HSPF) is a heating efficiency rating for heat pumps. The higher the rating, the more efficient the heat pump. 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 heat pump.
How important is HSPF?
When it comes to heating devices, there is no single specification more important than the HSPF rating. HSPF rating is the key metric for all heating devices; be it heat pumps, furnaces, or water heaters. Understanding it gives you the fundamental insight into all heating devices.
What is the difference between COP and 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. Since both numerator and denominator are in joules, COP is unitless.
What is a SEER?
SEER stands for Seasonal Energy Efficiency Ratio. This is the ratio of the cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in Watt-Hours. It may also be called a Seasonal Energy Efficiency Rating.
How do I get HSPF?
The HSPF is calculated by taking the total heating required during the heating season, in British thermal units (BTUs), and dividing it by the total electricity consumed during the same time period.
What is HSPF and SEER?
SEER stands for Seasonal Energy Efficiency Ratio and applies only to cooling. (It’s not a great measure of efficiency, but that’s the topic of another article.) HSPF stands for Heating Season Performance Factor and is basically the SEER rating for winter.
How do you find the HSPF?
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).
What is HSPF IV?
The HSPF is a single value that is intended to represent the overall efficiency of the heat pump for the entire heating season, and is the ratio of output capacity in BTU/hr (Btuh) to power input in watts.
What is a female SEER called?
In Germanic paganism, a seeress is a woman said to have the ability to foretell future events and perform sorcery.
What is SEER in the Bible?
“A seer is one who sees with spiritual eyes. He perceives the meaning of that which seems obscure to others; therefore he is an interpreter and clarifier of eternal truth. He foresees the future from the past and the present.
How is HSPF tested?
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 EER HSPF?
The SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations. Both ratings are important when choosing a product. Heat Seasonal Performance Factor (HSPF) is the most commonly used measure of a heat pumps heating efficiency.
What is HSPF and how is It measured?
HSPF is a metric of energy-efficiency measured throughout the winter heating season. Every winter, we can measure: Electricity we spend on heating; the power use in kilowatt-hours. Heating effect we get; the heating capacity in BTUs. Example: To heat out 1500 sq ft home during the 3-winter months (December, January, February), we spent 20,000 kWh.
What is the difference between HSPF 8 and 10?
HSPF 8 = $2,638 per heating season in electricity costs. HSPF 10 = $2,110 per heating season in electricity costs. You can see that (in our example) higher HSPF 10 device produced $500 fewer electricity costs than lower HSPF 8 device.
Is a higher HSPF rating better for my heat pump?
Higher HSPF rated heat pumps are more energy efficient, which is a good thing for both the environment and your wallet! Heat pumps with higher HSPF ratings can run more efficiently while using less energy, so they may cost you less each month in utility bills.
How many cops are in a HSPF?
