Geothermal systems provide an efficient and effective alternative to the more traditional “furnace and air conditioner” approach. At the core of the system is a heat pump, designed to transfer thermal energy from a “source” to a “sink”. In winter, the source is the ground, where heat is retained and sent to the building to warm it. In summer the system works in reverse.

Although geothermal has been around for more than 60 years, rising energy costs (along with government rebates) have made this system more popular, especially in commercial use.

At Delta, we’ll be pleased to specify a geothermal system for your needs, one that will save significant energy and keep you comfortable all year round.

Split Systems

Provide installation flexibility with the capability to be installed with a remote air handler. WaterFurnace geothermal splits can be used to provide comfort for the entire home, or individual zones like the second story on a large home. Using geothermal split systems in conjunction with a fossil fuel furnace “turbocharges” the system for increased efficiency.
