HOTWATERMANAGEMENT.ORG

natural Devices is a business started by Glenn C. Koenig in 2009, after he installed a solar heat and hot water system in his house and changed out his old toilets for new low flow models. In the process of working on these projects, he came up with a number of ideas to go further, to save both energy and water. Rather than just install them in his own house, he decided to share them with the rest of the world.
