Cop And Spf For Heat Pumps Explained Seer stands for seasonal energy efficiency rating. the seer number lets you know how energy efficient the heat pump is at cooling your home. by law in the usa and canada, a heat pump has to have a seer rating of at least 13, but the rating scale goes as high as 21. the higher the number, the more efficient the cooling provided by the system. Seasonal performance factor (spf) of heat pumps. where cop gives us efficiency of a heat pump at any given time, spf gives us the same but for annual performance of the heat pump. air source heat pumps use heat energy from the outside air and ground source heat pumps use heat energy from the ground. the heat pump needs to raise the temperature.
What Is The Cop вђ John Cantor Heat Pumps In mathematical terms, the cop is calculated by dividing the heat energy output by the input energy. the resulting number is the cop rating. as an example, if for every one kw unit of electricity used you achieve 4 kw units of heat, then your heat pump has a cop rating of 4, or a 400% cop. the higher the cop number, the more efficient your heat. The spf of a heat pump is the ratio of annual heat generated to the annual electricity consumed for the operation of the heat pump. as a formula this is calculated as: spf = total heat output per annum total electricity consumed per annum. spf tells how efficient a heat pump is on average. article cop and spf for heat pumps explained. Check. heat pump coefficient of performance (cop) is a measure of your heat pump’s efficiency based on energy output vs energy consumption. the higher the cop, the better, as this means you get more energy out of your heat pump than what you put in. a cop of 4 means your heat pump produces 4x more energy (heat) than it consumes (electricity). A well designed ground source heat pump installation should achieve an spf of 3.5, or over 5 if linked to a solar assisted thermal bank. [6] example: for a heat pump delivering 120,000,000 btu during the season, when consuming 15,000 kwh, the hspf can be calculated as : hspf = 120000000 (btu) (1000) 15000 (kwh) hspf = 8.
