Heat Regain from Down the Drain

Every day, our money and energy is wasted as we pay to heat up our shower water and then waste it down the drain. My innovation, the SHIFT (Shower Heat in Floor Tiles) system extracts the heat from shower waste water using a heat exchanger and uses that heat to power a hydronic heating system beneath the bathroom floor. The colder waste water would then come into contact with a second heat exchanger which would send the remaining heat to the incoming water in the hot water boiler.
