    How do I determine the maximum theoretical coefficient of performance for a heat pump operating at steady state between a dwelling at 70 deg F and a pond at 40 deg F?

    For the dwelling, if heat transfer through the walls and roof is 6.5x10^5 Btu per day, how would I determine the minimum theoretical power, in hp, to drive a heat pump operating at steady state between the dwelling at 70 deg F and a pond at 40 deg F?
