Input Parameters

Imperial (°F, BTU, ft)SI (°C, kW, m)

Heating Load (BTU/hr)

Cooling Load (BTU/hr)

Ground Temperature (°F)

1,000

Borehole Length ft

Number of Boreholes

Formula:

Q_{max} = \max(Q_{heat}, Q_{cool})

Calculation:

Q_{max} = \max(50000, 40000)

Result:

50000 \text{ BTU/hr}

Formula:

L = \frac{Q_{max}}{50}

Calculation:

L = \frac{50000}{50}

Result:

1000 \text{ ft}
