This problem is supposedly easy but I just can't figure out how to do it.(adsbygoogle = window.adsbygoogle || []).push({});

A heat pump is used to heat a house and maintain it at 24°C. On a winter day when the outdoor temperature is -5°C, the house is estimated to lose heat at a rate of 80,000 kJ/h. Determine the power required to operate this heat pump

Only two equations I know are: COP = Qh/(Qh-Ql) = Qh/W

where W is the net work done (what I'm looking for).

In the book, they have an example just like it except the COP is given so all I gotta do is plug numbers in the equation and get the answer but I don't know how to do it when the temperatures are given instead of the COP.
