Who We Are

Total Green Mfg. partnered with the largest direct exchange manufacturer (Earthlinked) in North America, and after a 5 year partnership, we acquired the 38 year old company. Earthlinked Technologies Inc. was originally known as ECR Industries and manufactured direct exchange geothermal equipment under both names. Today the Waterless® Geothermal equipment manufactured by us can be a direct replacement for these older direct exchange geothermal designs.
