Heat from domestic waste water, including residential and commercial washing machines, showers, dishwashers, and other appliances, can be recovered using a variety of heat exchangers. The most common, a gravity film heat exchanger (GFX), takes advantage of water’s surface tension. In these units, warm drainwater clings to the interior of a copper center pipe, around which a smaller-diameter copper pipe is coiled.
