A water heater tank is designed to be installed within a wall to provide substantially instantaneous and continuous hot water when the faucet is activated. The tank maintains water at a hot temperature to be mixed, if necessary, with standing water from the main hot water line. The tank includes a narrow channel through which the water traverses as it proceeds through the tank. A controller calculates the appropriate mixing ratio of the water sources depending on the desired water temperature.
