What Does Geothermal Loop System Mean?

A geothermal loop system is a heating system with underground looping pipes that are filled with a liquid such as anti-freeze that aids transfer of ground temperature to the geothermal heat pump.

There are two types of geothermal loop systems namely open loop system and closed loop system. Geothermal heating systems are gaining popularity because they are environment friendly and economical compared to other heating methods. Trenchless techniques such as horizontal directional drilling can be used to help pass the pipe under the ground without breaking open the yard or the driveway.


Trenchlesspedia Explains Geothermal Loop System

The geothermal closed loop system has continuous looping pipes that are filled with anti-freeze to help temperature transfer. It can be installed vertically or horizontally depending on the available space in a property. T

he vertical loop is preferred because it requires minimum space. An open loop system requires an adequate ground water source making the system somewhat uncommon.

The system is connected to a well or a pond and directly pumps the water to the heat pump located at the building for heating or cooling. The water is disposed by surface drainage to a low lying pond or river or by pumping it back to the water source.
