WebAn air source heat pump is designed to have a HSPF of 7.8 btu/Wh. If the heat pump is to utilize 2,700 kWh of electricity during the winter season, how many btu's does the heat pump need to provide? Select one: O a. 21,060,000 btu's b. 5,775,000 btu's O c. 21,000 btu's O d. 10,000,000 btu's O e. 42,120,000 btu's. WebA Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius). One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu. A typical window air conditioner might be rated at 10,000 Btu.
