A house is maintained at a temperature of 25oC by a reversible heat pump powered by an electric motor. The outside air at 10oC is used as the low-temperature TER. Determine the percent saving in electrical power consumption if the house is kept at 20oC instead. Assume that the heat loss from the house to the surroundings is directly proportional to the temperature difference.
