Geothermal Ground-Source Heat Pumps: 30% Federal Tax Credit & ROI Analysis

Geothermal ground-source heat pumps move heat between your home and the earth, where temperatures remain a steady 50°F to 60°F year-round. This subterranean thermal stability provides steady COP efficiencies exceeding 4.0 even in harsh freezing winters.

Under Section 25D of the US Internal Revenue Code, homeowners installing qualified geothermal heat pumps can claim an uncapped 30% federal clean energy tax credit covering total equipment, loop drilling, and installation costs.

Vertical borehole loops are ideal for tight suburban lots, while horizontal ground loops work well on larger acreage. Desuperheater options harvest excess compressor heat to supply up to 70% of your household's domestic hot water for free.

While upfront drilling increases initial investment, lower operating costs and 50+ year loop lifespan deliver impressive long-term return on investment.
