Disclaimer & Accuracy Margins: This simulator provides an indicative engineering estimate. The Total Active Pipe Length for horizontal loops relies on general soil profiles and represents only the active heat exchange area; it does not include the runout pipes connecting the trench or bore to the mechanical room. The Vertical Bore Depth is calculated using the VDI 4640 standard for medium-conductivity geology (approx. 50 W/m) and indicates the drilling depth required. For a standard out-and-back U-tube, you must purchase twice this depth in pipe (indicated in parentheses). The vertical calculation has an estimated error margin of ±15% to ±20%, as deep-earth temperatures remain relatively stable regardless of surface climate extremes.

The HVAC thermodynamics and latent cooling coefficients are derived from ASHRAE Fundamentals. These results are NOT a final installation blueprint. A local certified geothermal engineer or driller MUST recalculate and verify exact bore depths and loop lengths based on site-specific Thermal Response Tests (TRT), local groundwater flow, and regional building codes before purchasing materials or drilling. GHT Solutions assumes no liability for system sizing or performance.
