Based in Saint Henry, Ohio, Waterless™ DX Geothermal manufactures patented direct-exchange geothermal heating and cooling systems that move heat through buried copper loops rather than water. The Total Green Manufacturing team brings DX experience dating to the early 1990s, and its equipment is made in the USA for residential and commercial properties, including retrofit projects that can reuse existing DX ground loops. Its compact loop designs can reduce the amount of yard disruption while providing heating, cooling, and optional hot water from one system.
