How Does a Geothermal System Provide Heat?

When looking at a combustion heating system like a furnace or boiler, it’s pretty clear how heat is generated for your home. But when you look at the components and layout for a geothermal system, you can be left shaking your head. Rest assured that a geothermal system can more than adequately heat your home in Hendersonville, NC, but understanding how this system does so can go a long way toward giving you peace of mind about it.

Transfer of Heat

One of the key components of a geothermal system is the ground-source heat pump. Heat pumps work by transferring heat from one location to another using refrigerant or environmentally-friendly anti-freeze to facilitate the process. The way a geothermal system provides heat for your home during the winter months is by allowing the solution in the ground loop (which is usually eco-friendly anti-freeze) to absorb the latent heat in the ground below the frost line. The solution transfers the absorbed heat to the ground-source heat pump where it is concentrated, and once the heat reaches the right temperature, it is dispersed to your home via ductwork or ductless indoor blowers.

Will It Provide Enough Heat?

In a word, yes. One of the reasons geothermal HVAC systems are so reliable is because of their source of heat: the ground beneath the frost line. You may be thinking that the ground at this level would be awfully cold, but the temperatures stays in a steady range between 55-61 degrees. This give the geothermal system plenty of heat to draw from for your home, and you never have to worry about running out of soil!
