Assume that you heat your home with a heat pump whose heat exchanger is at tc=2∘c, and which maintains the baseboard radiators at th=47∘c. if it would cost $1000 to heat the house for one winter with ideal electric heaters (which have a coefficient of performance of 1), how much would it cost if the actual coefficient of performance of the heat pump were 75% of that allowed by thermodynamics?
