Efficient Heating & Cooling
The following Home Heating Cost Comparison identifies the most efficient heating source as a heat pump, specifically a geothermal heat pump. The most expensive way to stay warm is by a propane gas furnace. The costs reflect the dollar amount to heat your home during the winter season.
An average efficiency heat pump would save you $400 compared to an average efficiency gas furnace. Federal tax credits to install heat pump systems are available to homeowners.
Spotlight on Geothermal
Geothermal relies on the Earth's natural thermal energy to heat and cool water underground. The system can operate very efficiently because the temperature underground is about 57 degrees. As a result, geothermal uses 40-60% less energy than a standard heat pump and reduces harmful greenhouse gas emissions. Many Nashville-area organizations, businesses, and communities are looking to geothermal as an alternative energy option, including:
The first low-income housing development in the state to go geothermal
Installed a geothermal heat pump during renovations to the Burton School of Pharmacy
Replaced the home's electrical system along with other energy efficient improvements
