A ground source heat pump (GSHP) extracts heat directly from the ground. The sun heats the earth every day, meaning the rock or soil beneath the surface can offer a natural source of consistent low-grade heat.

Property owners can install a vertical or horizontal ground source system. The former uses deep drilled boreholes, and the latter uses shallower trenches. The system circulates a solution through pipes or loops, which absorbs the underground heat and passes it through a heat exchanger into the pump.

A ground source heat pump is a super-efficient heating system, delivering year-round heat to residential and commercial properties.
