Ground source heat pumps (GSHPs), often called geothermal heat pumps, tap into the heat naturally generated many meters below the surface of the earth.  Just a little ways down, the earth's temperature is warm and relatively stable, so these systems can bring controllable and effective heating, cooling, and hot water to residential and commercial buildings.  Best of all, they allow people to do all this without having to use expensive and carbon-producing fossil fuels such as oil and gas.

   There are two types of ground source heat pump systems: those with closed loops and those with open loops.  In closed loop systems, liquid (usually with some sort of antifreezing/antiboiling agent mixed in) circulates through pipes buried beneath the earth's surface.  During the winter, when the goal is warming a house, the fluid absorbs heat from the earth and carries back to the building.  This very hot liquid can be effectively used to heat a home, and also quite obviously becomes a free-flowing source of useable hot water.  During the summer, the system is designed to actually draw heat out of the building, and either use it to heat water for household use or deliver it back into the ground.  Open looped systems are similar, except that the water supply within the pipes is continually refreshed.
