Determine minimum power required to operate heat pump

A heat pump is used to heat a house and maintain it at 20 °C. On a winter day when the outdoor air temperature is -5 °C, the house loses heat at a rate of 75000 kJ/hr. Determine the minimum power required to operate this heat pump in kJ/hr. How much work would be required to provide the heat from a 100% efficient electric heater instead of a heat pump?
