Answer:

$187.61

Step-by-step explanation:

Data provided:

Temperature of the heat exchanger, Tc = 2° C = 273 + 2 = 275 K

Temperature of the base board radiators , Th=47° C = 273 + 47 = 320 K

Cost of heating the house = $1000

Coefficient of performance of the heat pump = 75% = 0.75

Now,

Actual performance = 75% of performance of heat pump

Actual performance = 0.75 × $\frac{\textup{Th}}{\textup{Th-Tc}}$

Actual performance = 0.75 × $\frac{320 K}{320-275}$

Actual performance = 0.75 × $\frac{320}{45}$

Actual performance = 5.33

Therefore, the cost = $\frac{\textup{1000}}{\textup{5.33}}$

cost = $187.61
