PROBLEM TO BE SOLVED: To provide a stove with a built-in hot-water heat exchanger preventing the generation of boiling sound due to the heating of the hot-water heat exchanger to a high temperature even at the time of the single operation of the stove. SOLUTION: This stove is provided with a burner part 1 producing combustion gas by combustion, a main heat exchanger 13 circulating the combustion gas produced by the burner part 1 to generate heat for space heating by radiation and convection from the surface, a bypass 19 bypassing the main heat exchanger 13 from the burner part 1 to bring the combustion gas into communication; and a hot-water heat exchange chamber 24 storing a hot-water heat exchanger 23 inside to allow it to perform heat exchange with the combustion gas. A damper chamber 20 communicating with an exhaust path 25 and having a damper for switching paths is provided among the main heat exchanger 13, the bypass 19, the combustion gas and the hot-water heat exchange chamber 24. At the time of the single use of the stove, a communication is provided between the main heat exchanger 13 and the exhaust path 25, and the communication on the bypass 19 side is shut off. Thus, the stove capable of preventing boiling sound securely and used at ease is provided.
