stopping consumption of water from the gewh thus reducing or stopping energy consumption associated with heating newly introduced water into 10 water flow from inlet 15 to outlet 16 having a temperature below desired minimum hot water supply temperature causes water flow to become reduced on inlet 15 and increased on inlet 14 thus maintaining desired minimum hot water supply temperature to outlet 16 referring to fig3 the third temperature controlled water distribution valve 18 provides water distribution to be via the gewh when the desired activation temperature is reached the third valve serves to prevent water over a certain temperature typically approx 130 u00b0 f or that of just over the gewh from bypassing the water heater and will cause water to again flow through gewh once a temperature over 130 u00b0 f is reached thus allowing the hot flow via gewh to aid in storage of hot water the temperature adjustment 22 of third temperature controlled water distribution valve 18 must be set for a desired activation temperature based on thermostat temperature setting of gewh typically 130 u00b0 f upon water flow from either of inlets 20 or 19 to outlet 21 having a temperature above the desired activation temperature will cause water flow to.
