A safety and energy saving improvement to a hot water heater whereby water can be heated to a high temperature (scalding hot) required for sanitizing and energy storage, but then is is internally cooled to a lower, non-scalding temperature before it leaves the heater. This is accomplished by means of a low-cost internal heat exchanger. In its simplest form, the internal heat exchanger is a vertically oriented tube structure one end of which is open to the hottest water at the top of the tank and the other end of which exits the tank. By sending the hottest water downwards through this tube, the hot water passes through the cooler layers of water in the tank and so gives up heat energy resulting in a lower water exit temperature. To maximize heat transfer where high storage temperature is preferred, the heat exchanger includes a larger outer sleeve which surrounds the vertical tube structure and into which sleeve the cold feed water is made to flow through the annular space therebetween. Also disclosed are means to automatically move the sleeve and/or deflect the cold water flow path to automatically vary heat transfer in response to the seasonal change of temperature of the cold feed water.
