This expansive property is a 20,000 sq ft single family residence in Tuxedo Park, New York, with many heating and cooling requirements and challenges. Natural Energy Solutions assessed the home and designed a system with eleven geothermal units for heating and cooling, two geothermal units and three racks of evacuated tube solar thermal for domestic hot water, two pools, a spa, and a koi pond. Both the family and the koi now live comfortably in this beautiful home throughout the seasons.
