Zero Maintenance

ReTherm is 100% maintenance free

 

Many products claim to be zero maintenance, but in reality still require some maintenance. ReTherm drain water heat exchangers are designed to operate decade after decade with absolutely zero maintenance. When it comes to saving energy they are as simple as insulation: install it and let energy savings accumulate.

With no moving parts or valves to seize, break or wear-out it shouldn't come as a surprize that there is no maintenance involved. Older style drain water heat exchangers built in the 70's and 80's required yearly cleaning to maintain top performamce, but ReTherm never requires cleaning. The rapidly flowing vertical water film self-scours the inner wall of the heat exchanger preventing any build-ups that would reduce heat transfer and energy savings.
