What Is the Minimum Power Required for a Heat Pump to Maintain 20°C?

[samirnasri]

Hello,
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?

You get an A+.
The + is for brevity.
