What are Ground-Source Heat Pumps

Ground-source heat pumps, often called geo-thermal heat pumps, tap into the earth or a source of water for residual heat. There are all kinds of ways to connect the heat pump with the ground. In most cases, loops of plastic tubing filled with a nonfreezing fluid are buried in trenches that may stretch hundreds of feet around a building site. Tubing can also be dropped into one or more vertical walls, a technique that takes a lot less room but can be quite costly. Tubing can be placed at the bottom of a nearby pond, or water from a well can be the source of latent heat.

Types of Ground-Source Heat Pumps

Horizontal Ground-Linked Heat Pump

Tubing filled with antifreeze absorbs heat from the ground and carries it to a ground-source heat pump. Even in winter, underground temperatures are high enough to allow the system to work, but hundreds of feet of tubing must be buried and excavation can be extensive.

Open-Loop System Where Water is Abundant

With an open-loop system, water is pumped from a well through the heat pump and returned to earth. It passes through the system only once. If the well produces enough water, it can be used for both domestic supplies and the heat pump.

Closed-Loop Vertical System Recirculates Same Fluid

Tubing can be placed in one or more vertical wells if there isn't enough room for horizontal trenches. The number and depth of the wells depends on a variety of factors. A closed loop of nonfreezing liquid absorbs heat from the earth and moves it to the heat pump inside, where it is concentrated and distributed around the house.

Comparing Heat Pump Performance

The highest performing ground-source heat pumps on the market offer excellent energy savings over their lifetime-at least on paper. In one simulation from the U.S. Department of Energy, the most efficient heat pump was expected to use only about one third of the energy for heating as a standard air-source heat pump, 10,900kWh vs. 29,800kWh. Savings for cooling were not quite as dramatic, but overall the simulation estimated that annual energy savings were better than 2 to 1 with the ground-source heat pump.

However, anecdotal evidence suggests that ground-source heat pumps can be finicky and disappointing. Efficiency is described as a coefficient of performance (COP) which is the heating capacity  of the device in Btu divided by the electrical input.

A heat pump with a COP of 4 produces 4 units of energy for every 1 unit of electrical energy it co...
