the coefficient of performance of this heat pump is 8.61.
What is Heat pump ?
The air source heat pump converts heat from the ambient air into a low-temperature liquid refrigerant. The pump compresses the liquid to raise its temperature using power. To release the heat it had been holding, it then condenses back into a liquid. Your underfloor heating system or radiators get heat.
coefficient of performance -The usable heating or cooling delivered to work (energy) needed ratio, also known as the coefficient of performance, or COP, of a heat pump, refrigerator, or air conditioning system. Higher efficiency, less energy (power) usage, and thus reduced operational costs are all related to higher COPs.
temperature of cold reservoir = -14.0°C
Tc = [ 273+ (-14.0)]K = 259K
temperature of hot reservoir = 20°C
Th = [ 273+ (20)]K = 293K
therefor, formula for coefficient of performance
Cop = Th/Th-Tc
Cop = 293/34
Cop = 8.61
