を防止することを特徴とす水加熱器。 In a water heater in which two circulation circuits are connected to one heating heat exchanger via a switching valve, and forced circulation is performed by a circulation pump, a water flow switch is installed in the water passage to control the flow of water in both circulation circuits. Detects the presence or absence of water,
When water exists in both circulation circuits, the switching valve is operated at regular intervals to allow water to flow through both circulation circuits alternately, and when water in one circulation circuit runs out, water is passed through the other circulation circuit. A water heater characterized by allowing water to flow only through the parts to prevent connection.
