A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.

The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank.

A hot water pulsating alarm system and method for electric or gas-fired water heaters is described. A sensor senses the water temperature in an upper region of the water tank of the water heater and feeds temperature signals to a controller. The controller operates an electromechanical valve connected to the pressurized cold water supply line of the water tank. Upon detecting a low temperature value stored in the memory of the controller, the controller causes a shut-off electro-mechanical valve to close and open in a predetermined sequence and during a predetermined time period. This causes interruptions of hot water being drawn from the upper region of the water tank to feed a hot water supply conduit and creating a pulsating water temperature change in hot water being discharged through fixtures connected to the hot water supply conduit. The pulsating temperature change is detected by a user person having a body part in contact with water dispensed from fixtures secured to the hot water supply conduit and indicating to the user person that the water heater will be shut-off.
