The Earth absorbs almost 50% of all solar energy and remains a constant temperature of 50°F to 70°F depending on geographical location. A geothermal unit utilizes this constant temperature for heating and cooling your home. You can save up to 60% on your power bills compared to a traditional system. There is no flame, no flue, no odors and no loud outdoor equipment. Heating, air conditioning, and hot water can all be attained from a single compact unit.
