Drain water heat recovery - Récupérateur de la chaleur des eaux de drainage

Drain water heat recovery (DWHR). ThermoDrain is a drain water heat recovery unit that recovers energy from waste water and transfers this energy to potable water before entering a water heater. It is different from other heat exchangers in that it has dual walls vented to the atmosphere so that cross contamination between wastewater and potable water is not possible. The heat transfer occurs only when wastewater is flowing down the drain while there is a demand on the hot water heater. This technology can save the homeowner up to 40% on their water heating bills. It can also triple the capacity of a hot water tank for showering. It is considered a comfortable green technology designed for shower lovers who also want to save energy. ThermoDrain is a superior drain water heat recovery technology that is manufactured in North America and comes with an industry leading 10 year warranty.
