Sanitary system for supply of hot and cold water, and thermostatically controlled valve for such system

A sanitary water distribution system for supplying hot or cold water or mixtures thereof of any desired proportion from a central location to a plurality of tapping locations, said system comprising:

• a plurality, equal to the plurality of tapping locations, of thermostatically controlled water mixing valves located at the central location and remotely from respective of the tapping locations;
• a hot water storage heater connected to supply hot water to each of said mixing valves;
• means for supplying cold water to said hot water storage heater and to each of said mixing valves;
• each said mixing valve including valve means for varying the proportion of hot and cold water mixed and discharged thereby;
• each said mixing valve having extending therefrom to a respective tapping location a respective single pipeline for the supply of water from said mixing valve;
• each said pipeline having connected thereto, at the respective tapping location, a respective manual tapping valve for controlling the quantity of water discharged therefrom;
• manually operated means at each tapping location for selecting a desired temperature of water to be discharged by the respective said mixing valve through the respective said pipeline and tapping valve;
• display means at each tapping location and responsive to the respective said manually operated means for displaying the respective selected desired temperature;
• and
• processor control means, responsive to a respective said manually operated means and operatively connected to said valve means of a respective said mixing valve, for adjusting the proportion of hot and cold water mixed and discharged by said mixing valve in response to and as a function of the desired temperature selected by said manually operated means.
