The neighborhood where the house is located in East Amherst, NY is 50% Green Space and the first Certified Green Neighborhood in NYS. It is Energy Star "Green" certified w/Geothermal Heat & Solar Power equals LOW or NO utility bills! Geothermal systems function because of the Earth's natural heat resources. The ground will absorb about 50% of the Sun's energy and is then naturally absorbed into the pipes underground, which are about 8' below where the Earths temperature is always about 50 degrees. The Sun heats the Earth. This heat is transferred to water-filled underground pipes I took a tour of the home and the neighborhood and was quite impressed. Here is the listing to see more info. https://nys.mlsmatrix.com/DE.asp?ID=2173652648
