About Us

ReTherm Energy Systems has been a premier manufacturer of drain water heat exchangers since 2004. Our mission is to provide home and business owners with cost-effective solutions that substantially reduce domestic water heating costs by focusing on waste heat energy. By reducing the energy that is wasted the amount of energy needed is also lowered. Energy savings and lower energy bills are just that simple.

ReTherm - A Green Business that's getting even Greener
When ReTherm started making drain water heat exchangers we wanted not only to be making green products, but we also wanted to be running a green business. We wanted to be working towards a cleaner, healthier, and sustainable environment for us and future generations. In early 2007 we began sourcing 25% of the electrical power used at ReTherm Energy Systems from clean, renewable wind power.
