I'm not going to lie and say I don't love a hot, hot shower. And, I'll admit, I fancy myself a long, hot shower sometimes, too. But I pay for it, and so does the environment. Unfortunately, every time I shower, that hot water disappears down the drain, instead of being harnessed for another purpose. Thanks to the EcoDrain, that needn't any longer be true. The unique heat exchanger transfers the heat from hot shower waste water to cold incoming water, cutting water heater use down by 25 to 40 percent. This small handy device is easy to install directly in the shower drain line, and separates the fresh water from the waste water to prevent them from mixing. Unfortunately, it's currently only available in Canada, but I hope one day to see it in homes worldwide.
