What if we could recapture this untapped source of wasted energy by transferring the heat from that shower waste-water to cold incoming water? The EcoDrain, a simple heat exchange unit, does just that, saving water heater use by up to 40%.As one who loves a long hot shower, I need one of these pronto.
Showering is “likely your most energy-intensive daily household activity. Although hidden on your energy bill, heating water for showers represents a significant portion of the total.” The EcoDrain is a simple heat exchange unit with no moving parts that is “easy to install” and needs no maintenance.
