A heat pump is to be used for heating a house in winter. The house is to be maintained at 78°F at all times. When the temperature outdoors drops to 25°F, the heat losses from the house are estimated to be 70,000 Btu/h. Determine the minimum power required to run this heat pump if heat is extracted from (a) the outdoor air at 25°F and (b) the well water at 50°F.

Question
A heat pump is to be used for heating a house in winter.
The house is to be maintained at 78°F at all times. When
the temperature outdoors drops to 25°F, the heat losses from
the house are estimated to be 70,000 Btu/h. Determine the minimum
power required to run this heat pump if heat is extracted
from (a) the outdoor air at 25°F and (b) the well water at 50°F.
