I have developed and patented a control technique that can be attached to any hot water heating system and will protect the pipes that distribute hot water in the building from freezing. This device can also be connected to an alarm systems to provide a quick notification that the heating system can no longer deliver heat to the building, even on a warm day when the system is not running. The device is simple to use and can be easily connected to existing heating systems. The attached presentation provides additional details about the technology and products that are in the process of development based upon the technology. I would like to market or license this device and would appreciate comments.
