Add this cool looking water heat recovery device to your shower drainpipe. It reduces your carbon footprint and cuts water heating costs by about half, by re-using your water heat energy to preheat the incoming cold water. There are also commercial sizes available, that are installed in buildings that use a lot of hot water like hospitals, hotels, seniors’ residences, and food manufacturing plants. The more hot water being used, the faster these devices pay for themselves.
