FollowPower Pipe is a brilliant, easy-to-install heat exchanger that can save a bundle on home energy costs by using hot drain water to heat incoming cold water. Statistics from the U.S. Environmental Protection Agency show that 20%-30% of all household energy goes toward heating water, so lessening this energy draw can have a large effect on homeowner utility bills. The system works by wrapping your bathtub drain pipe with layers of highly conductive copper coils, which effectively transfer heat from the waste water draining down the pipe.
