Most commonly, geothermal systems are used to provide forced air heating and forced air cooling to the home. Traditional ducting is used to deliver the warm or cool air throughout the home. In existing homes, care must be taken to ensure that the existing ductwork was designed properly and can deliver the right amount of air to each room.
Geothermal systems are able to be used to produce hot water for radiant in-floor heating. Since baseboard radiant heating applications require water temperatures in the 160 – 180 degree range, geothermal systems are not suitable for a direct replacement of a boiler. In some instances, however, geothermal may be used to supplement the boiler.
In some homes, there are two methods of delivering heat. For example, some homeowners like to heat the lower level of tile areas with radiant heat and provide forced air heating and cooling through the rest of the home. In this type of application, a Combination Geothermal System can be used. These systems have the ability to produce hot water for radiant heating areas and forced air for the rest of the home. In some cases it is better to use two separate units to accomplish this. Our expert designers will assess your situation and recommend the best design for your home.
Do you have a newer furnace but want to reduce your energy bills? This is where a Geothermal split system can help. If your current furnace is relatively new, a geothermal system can be added onto the furnace much like an air conditioner gets installed. Geothermal split systems consist of two pieces: the compressor section and the “A” Coil. The compressor section is located in the home, usually in the vicinity of the current furnace. The “A“ coil is installed above the furnace in place of the existing air conditioning coil if you currently have A/C. The two sections are connected by copper refrigerant lines called a line set. From here, the geothermal system operates and provides the first stage of heating to the home. During colder weather, the furnace takes over for the geothermal system. The geothermal system will also provide all of the cooling during the summer months. This application will not save you as much energy as a complete “package” geothermal system that replaces the furnace, but it will have a slightly lower upfront cost.
Outdoor or indoor swimming pools can consume a tremendous amount of energy over the course of a swimming season. Geothermal systems – the same ones used for radiant in-floor heating – can be used to provide economical pool heating. On average, you can save 50% - 70% on pool heating over natural gas and propane.
