As a highly efficient and effective approach to home heating and cooling, geothermal is on the rise in popularity for homeowners throughout the Midlands and across the country. If you are considering making the switch to geothermal, but still have a few questions then take a look at our FAQs below. Feel free to give us a call if you can't find the answers you are looking for.
Yes, there are two types of loops: closed and open. Both of these types function slightly differently, but still work for both heating and cooling – delivering geothermal benefits directly to your home.
Absolutely. Some available geothermal heat pumps are able to supply your home with hot water and do so at the same level of efficiency that they are already at heating or cooling your home. With the addition of a desuperheater, heat pumps can even heat your water outside of your hot water tank, easing the process and delivering savings.
Because their main goal is to work with nature, not against it. All of the hazardous gases that can be linked to global warming are not emitted through these systems. The system does not contain any chemicals or materials that are harmful to the earth, providing your home or business with a system that embraces the environment.
A closed loop is exactly what it sounds like, a sealed loop of pipes running underground. This type of loop circulates liquid to either release or capture heat from stable temperatures below ground. The heat pump forces a water-antifreeze solution through the loop and as it constantly circulates, heat is either transferred to or from these consistent underground temperatures. The size of the loop is directly related to the size of the home and its respective energy demands.
The temperature underground, 4 to 6 feet below the earth's surface, doesn't change with the seasons like outdoor temperatures; they stay relatively constant throughout the year. Geothermal systems have both an indoor unit and a buried earth loop, which uses these consistent temperatures for "free" energy to your home or business.
An open loop pulls groundwater into the heat pump, where heat is extracted, leaving water to be disposed of generally in one of two ways. First, the water can be discharged into a nearby body of water or into a ditch or drain. The second method would involve pumping the water back to the original source, likely through a second well to return the water below ground. Open loops allow homeowners to tap into groundwater that sits underground at a rather consistent temperature year round.
Geothermal systems do not burn fossil fuel in order to generate heat. Just by simply transferring heat to and from below the earth's surface, the system is able to provide more efficient and environmentally friendly heating and cooling to your home or business.
Geothermal systems are 3 to 4 times more efficient than most ordinary systems. They can provide up to 4 units of energy for every 1 unit used to power the system.
Geothermal systems are almost completely maintenance free. The loop that is buried below the earth's surface will last your home or business for years to come. The components that are housed indoors are protected from any harsh weather conditions. The occasional check from Comfort Services is all that's needed.
A geothermal system has three main parts - a heat pump, liquid heat-exchange medium, and an air-delivery system.
