Here are a few of the most energy-efficient ways to keep your home warm and toasty:
Heat Pumps - Not only do they heat and cool, but they do so while consuming much less energy than a standard furnace.
Geothermal Heating - Geothermal systems, which take advantages of the Earth's underground temperatures to control your home's climate, can cost up to 70% less than a regular heating system.
Ductless Mini Splits - These units are set up in individual rooms or zones, so if you choose you can only heat the spaces you're actively using. Plus, their lack of ductwork means you won't be subject to energy loss through leaks.
