Power-Pipe Drain Water Heat Recovery Unit

A Drain Water Heat Recovery (DWHR) system, such as the Power-Pipe, captures thermal energy from falling warm wastewater (such as shower drainage) to pre-heat incoming cold fresh water before it enters the water heater or fixtures.

The leading brand of this copper falling-film heat exchanger technology is Power-Pipe, originally developed and manufactured by RenewABILITY Energy Inc. headquartered in Kitchener, Ontario, Canada. These systems are commonly installed in energy-efficient homes across North America to significantly reduce residential water heating energy consumption.
