Emerging Technologies: Drain Water Heat Recovery PDF

Energy consumption for water heating accounts for 17% of residential and 7% of commercial site energy consumed. A study conducted by the U.S. Department of Energy found that approximately 350 billion kWh of energy is sent down the drain in the form of used hot water annually.
