For the past month, I’ve examined various home energy improvements for which one can earn a 30% federal tax credit. The last of these opportunities I’ll cover is ground-source heat pumps. A ground-source heat pump (GSHP) is also referred to as a “geothermal” heat pump, though I prefer the former terminology, to avoid confusion with true geothermal energyHot water or steam extracted from reservoirs beneath the Earth's surface; can be used for heat pumps, water heating, or electricity generation. The term may also mean the use of near-constant underground temperatures by ground-source heat pumps to provide heating and cooling. systems that rely on elevated temperatures deep underground from the Earth’s mantle.
