Recapturing some of the energy going down your shower drain could save you some money. The EcoDrain is a unique patent-pending heat exchanger which transfers heat from hot shower waste water to cold incoming water. The folks at EcoDrain estimate that this will cut water heater use by 25%-40%. The unit is installed directly in the shower drain line and features a double wall of separation between fresh and waste water; to eliminate the possibility of mixing, it’s lined with a non-stick coating to prevent soap, hair or debris from collecting inside.The device works primarily with the shower where hot water runs uninterrupted and doesn’t work with baths or dishwashers where water flow stops and starts. The company says the device is small, easy to install and has no moving parts. (see diagram).
