Is HSPF and SEER the same?
An HSPF rating, also known as Heating Seasonal Performance Factor, is the same efficiency rating as SEER. The only difference is that it measures the energy efficiency of heat pumps. It measures the ratio of heat energy delivered to your home to the amount of electrical energy needed to create it.
What is the HSPF of the most efficient air to air heat pumps?
The most-efficient Energy Star-rated heat pumps are 18 to 27.5 SEER and 8.5 to 12.5 HSPF.
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.
What is a good HSPF?
What is considered a good HSPF rating? Generally, you should look for heat pumps with a HSPF rating of between 8 and 10. Heat pumps with a rating of at least 8.2 HSPF are awarded the ENERGY STAR® label by the U.S. EPA.
What is a good HSPF rating?
What is a high HSPF rating?
A high HSPF rating is anywhere between 9 HSPF and 10 HSPF. In 2015, the Department of Energy set a minimum HSPF standard of 8.2, but this number is expected to increase to a mandatory minimum of 8.8 HSPF for all heat pumps by 2023.
Can you convert HSPF to COP?
Some heat pump systems use a different efficiency rating known as COP, or coefficient of performance. If you want to compare, you can convert HSPF to COP by multiplying the HSPF number by 0.293. An HSPF of 10, for instance, would be roughly equal to a COP of 2.93.
Is 9.5 HSPF good?
Generally, you should look for heat pumps with a HSPF rating of between 8 and 10. Heat pumps with a rating of at least 8.2 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 Seasonal Energy Efficiency Ratio (SEER) rating of 12 or greater.
Do heat pumps work below 20 degrees?
Do heat pumps work below 20 degrees? Yes, air source heat pumps work below 20 degrees Fahrenheit—in fact, they can perform well below -10! If you’re worried—or if you live in Antarctica—you can get a heat pump with a supplemental heating system in case of emergencies (the vast majority of people never need it).
What is a good efficiency rating for heat pump?
High cooling efficiency heat pumps: Generally speaking, models rated at 18 SEER and above should be considered highly efficient heat pumps. Some of the highest efficiency air-source heat pumps are rated at up to 20.5 SEER.
What is a HSPF model?
HSPF incorporates watershed-scale ARM and NPS models into a basin-scale analysis framework that includes fate and transport in one dimensional stream channels. It is the only comprehensive model of watershed hydrology and water quality that allows the integrated simulation of land and soil contaminant runoff processes…
What is the heating seasonal performance factor rating for HSPF?
Nevertheless, here are some common Heating Seasonal Performance Factor ratings with their COP: 1 8 HSPF = 2.34 COP 2 9 HSPF = 2.64 COP 3 10 HSPF = 2.93 COP 4 11 HSPF = 3.22 COP 5 13 HSPF = 3.8 COP
What does 10 HSPF mean on a heat pump?
Heat pump with 10 HSPF will give us 10 BTU’s of heat for every kWh. Obviously, it’s much better to have a heat pump with a higher HSPF rating (in this case 10). Such a heating device will draw less energy for the same heating effect, and you will pay less in heating expenses.
When was the HSPF published?
pre-release April 2014 for internal peer review. Hydrological Simulation Program – FORTRAN (HSPF) is a comprehensive package for simulation of watershed hydrology and water quality for both conventional and toxic organic pollutants.
