Abstract
A method and system for providing temperature-sensitive water delivery using thermostatic controls on home plumbing systems including showers, sinks, and bathtubs. A biometric device is utilized to record user fingerprints and associate the user with a desired temperature setting. An electronic temperature control component is used to accurately specify the desired water temperature for the particular water outlet and a thermostatic gauge is used to determine when the desired temperature is reached. When the desired temperature is reached, then a specified action occurs to display this indication. An output display is used to indicate the fact that the desired temperature has been reached or the flow of water is diverted back to the output of the faucet. The water is routed to an input reservoir until the desired temperature is reached for the purpose of preventing burns or too hot (or cold) water coming out.
