Geothermal Heating and Cooling Systems

Posted on: 1 February 2022

The temperature below the ground's surface is typically much warmer than the temperature aboveground. Geothermal energy is a term that refers to the heat that is trapped within the Earth's crust. A geothermal heating device can be used to supply a home or business with a renewable energy source. A ground level heat pump is used to transfer heated air into a structure.

How a Geothermal System Works

An HVAC contractor can install geothermal heating equipment. Some equipment is used to provide a home or business with heated and cooled air. The direction of the heat exchange that occurs while air is moved through a heat pump's pipes will dictate whether a heating or cooling action is performed. A contractor will need to install a heat pump on a parcel of land where geothermal energy will come from.

A heat-conveying liquid is used to transport heat from point-to-point. Heat can be transferred from the ground and into a home or business. It can also be transferred from a home or business and into the ground. 

Installation Essentials

A heat pump will be installed along the ground's surface. A series of pipes will be installed underground. Pipes can be laid out in a vertical or horizontal fashion. If heat will be obtained from deep in the ground, deep holes will be dug into the earth. The pipes will be set inside of the holes. Accessing heat that is deep within the earth will usually result in obtaining a large abundance of heated air that is at a high temperature.

If a horizontal piping format is going to be used, a contractor will access how long the piping sections will need to be. An excavator may be used to dig a narrow trench along the area where the pipes will be located. Once the pipes are connected and hooked up to the heat pump, dirt will be used to bury the pipe sections. With either type of piping layout, an end user will not be able to see any of the equipment that is working to transfer heated air.

The only component that will be visible is the heat pump. A heat-conveying liquid will be introduced into the piping. Water may be used as the liquid that will transport the heat. An end user will be supplied with programming features that will allow them to regulate the temperature of the heat that is supplied within the confines of their home or business.
