Abstract
A water heater (10) is suitable for point-of-use applications. The water heater includes a first temperature sensor, a second temperature sensor, and a controller connected to the first and second temperature sensors. The controller is configured to receive the signals generated by the first temperature sensor and the second temperature sensor and to detect a flow condition of water within the heat without using mechanical flow detection means and without supplying stand-by heating by adding an absolute value of the sensed change in temperature of water at the first temperature sensor to the absolute value of the sensed change in temperature of water at the second temperature sensor to yield a sum and then comparing the sum to a reference temperature.
