How Does a Geothermal System Provide Heat?

Pulling latent heat from the ground to heat your home during the winter months probably sounds like something from a Sci-fi film, but in very basic terms, that is precisely what a geothermal system does. And the method isn’t new – geothermal systems have been around since the 1940s. However, it has only been recently that these systems have become very accessible for homeowners. Geothermal systems offer a number of great benefits, but first let’s take a look at how they can provide heat for your home in Des Moines, IA.

The Components of a Geothermal System

There are three main components of a geothermal system:

  • The ground loop – this loop is buried in your yard 6-8 feet below the frost line and contains an environmentally-friendly solution that absorbs heat.
  • The ground-source heat pump – the heat pump is the driving mechanism for the system.
  • Ductwork or ductless blowers – the delivery system for the air.

The way a geothermal system heats is that the solution in the ground loop absorbs the latent solar heat that is in the ground. The temperature of the ground beneath the frost line stays a steady 55-61 degrees all year, all the time. This is one of the reasons why a geothermal system is so stable. The solution in the ground loop absorbs heat from the ground surrounding it, then transfers the heat to the ground-source heat pump. In the heat pump, the heat is concentrated and then dispersed to your home’s living spaces via ductwork or ductless indoor blowers. The heat is steady, comfortable and abundant.
