Calculation Steps

1

Calculate HSPF

Formula:

HSPF = \frac{Heating Output (BTU/hr)}{Energy Input (W)}

Calculation:

HSPF = \frac{36000.00}{3000.00}

Result:

12.00 \text{ BTU/W·hr}

2

Calculate COP (Approximate)

Formula:

COP \approx \frac{HSPF}{3.412}

Calculation:

COP = \frac{12.00}{3.412}

Result:

3.52 \text{ }

3

Calculate Annual Energy Cost

Formula:

Cost = \frac{P_{W}}{1000} \times Hours \times Price_{kWh}

Calculation:

Cost = \frac{3000.00}{1000} \times 2500 \times 0.12

Result:

900.00 \text{ $}
