Abstract
A water heater includes a case, in which a hot source, a cold source, a thermoelectric cooling chip, and a power requiring unit are provided. The thermoelectric cooling chip has a close loop with a hot junction adjacent to the hot source; and a cold junction adjacent to the cold source, that the thermoelectric cooling chip generates a current through the close loop when a temperature at the hot junction, is higher than a temperature at the cold junction. The power requiring unit is electrically connected to the close loop of the thermoelectric cooling chip; therefore, the power requiring unit may be driven by the power from the thermoelectric cooling chip, when the main power is low or off.
