    Answer:

    Q_{H}=6.4kJ/s

    Explanation:

    Given data

    Coefficient of performance of a residential heat pump=1.6

    Electrical power P=4kW

    Required

    Heat Q

    Solution

    The rate of heat produced is given as

    Q_{H}=COP_{HP}Win\\

    Substitute the given values

    So

    Q_{H}=4kW*1.6\\Q_{H}=6.4kJ/s
