It's hard to be a better steward of the natural environment than with WaterFurnace. Just ask the EPA — they confirmed geothermal energy is the most environmentally conscientious heating and cooling system. Or ask the U.S. National Renewable Energy Laboratory - they also determined that geothermal energy is more efficient and inexpensive than classic residential systems. Or ask the federal, state, and local governments and utilities - they're offering many rebates and tax incentives that will go hand in hand with your investment in geothermal. Or, most importantly, you can speak with your neighbors - more and more people are switching to geothermal and love it! Energy and cost savings will vary by region and depend on the type of old system your new geothermal is replacing. However, geothermal will always be smarter, cheaper and eco-friendly.
