Power-Pipe™ is a grey water heat reclaimer. By wrapping it directly around the wastewater pipe, the Power-Pipe™ transfers the calories from greywater to the cold water arriving at the hot water heater inlet and shower mixer tap. Power-Pipe™ was specially designed to reduce hot water production costs for residential, institutional, service and industrial uses (individual and multi-occupancy dwellings, hotels, healthcare establishments, swimming pools, etc.).
