On a cold (−10◦C) winter day, a heat pump provides 20 kW to heat a house maintained at 20◦C and it has a COPHP of 4. How much power does the heat pump require? The next day, a storm brings the outside temperature to −15◦C, with the same COP and the same house heat transfer coefficient for the heat loss to the outside air. How much power does the heat pump require then?
