Homework Help: Heat Pumps - Minimum Power

  1. Aug 29, 2011 #1
    Just wondering if you could help me out with this question;

    A house is to be maintained at 20°C in winter and the heating load is 10kW. The
    outside temperature is -5°C. If a heat pump is to be used to heat the house,
    what is the minimum power required to drive the heat pump?

    Would it be

    273.15+20 / 25 = 11.73

    10 / 11.73 = 0.85 kw?
