Geothermal Systems And Their Building Requirements

Geothermal Systems And Their Building Requirements

The geothermal system harnesses the earth’s heat to assist in both ways for various functions. The water is injected into the Earth’s crust. As Earth maintains a certain temperature, the injected water takes the heat and brings it back to the surface for the required usage.

This system is used in almost all sorts of projects. It works both ways depending upon the components and intention of the system. The system can take the heat from the earth’s crust and provide it for usage in the building. While at the same time, it can take the heat from the building and cool it down with the help of the earth’s crust depending upon the design of the system.

Building them is a task not to be trifled with. Let us have a deep look at various aspects of building these systems.

Building Geothermal Systems

Building this system is very much like other systems. There are certain components and their different capacities. Then, the internal elements of those components. Later, those elements come under various specifications. MEP contractors are hired to build them. They need all the required elements to put together the system. But before acquiring them, the information about those requirements is needed (for that, they have services like electrical estimating services). Lastly, by going through the whole procedure, the planned system is built.


Geothermal systems mainly include the components i.e., ground loop, heat pump furnace unit, a distribution unit, and the heat transfer fluid. Along with these, other optional components are used for these systems such as a desuperheater and auxiliary electrical heater.

The ground loop comes in various configurations. Thus, they are built accordingly. These configurations include:

  • Horizontal Closed Loop
  • Vertical Closed Loop
  • Well-To-Well Or Open Loop
  • Lake Or Pond Closed Loop

Working Of The Main Components

The ground loop is polyethylene pipes. These pipes carry the heat transfer fluid in a loop connected to the heat pump furnace unit. They perform the main function of carrying the heat in and out of the building.

The heat pump furnace unit is responsible for improving the heat flow in the required direction. This unit is more like an air conditioner. It performs functions of both heating and cooling. After improving it circulates the effect in the distribution system.

Finally, the distribution system. This includes the extensive duck network all around the building. For this network, duct takeoff services are the right option. This duct network often has an exhaust fan that forces the air into the ducts. As a result, the air is dispersed everywhere in the building.

Specifications Involved

The system contains pipes, ducts, an exhaust fan, a heat pump furnace unit, insulation, heat transfer material, and other elements. All these come in certain variations. Let us consider them individually:

  • Pipes are mostly used the ones made out of polyethylene. To have detailed information about them contractors can have plumbing estimating services
  • Exhaust fan comes in various electrical and mechanical capacity. Contactors need to acquire and install the right ones for the right results
  • Insulation is installed around the ducts. They need to be sufficient to ensure that the effect reaches the last place
  • The heat pump furnace unit is responsible to improve the effect and send. It needs to have the right force to get the job done


Geothermal systems hold great significance and function for all sort of buildings that resides life. To build these systems, contractors have to go through various things. These systems contain three compulsory and other optional components. Further, these components come in variations like other construction components. That is why contractors have to take care of them while building these systems.
