PURPOSE:To prevent the deterioration of a baffle body by a method wherein the baffle body, which is arranged at the upper part in a water tank, is made in a case type which cuts off combustion gas hermetically, and the inside of the baffle body and a hot air feeder are connected. CONSTITUTION:A burner 3 is arranged in a combustion chamber 2 at the inside of the water chamber 1, and the baffle body 4 in the shape of a cubic case is arranged at the upper part of the combustion chamber 2. The inside of the baffle body 4 and the hot air feeder 8 are connected with a tube 5 and 6, and the air to the hot air feeder 8 is also sent by a blower 9. As a result the temperature of the baffle body 4 is lowered, and the heat deterioration of the baffle body is prevented, and the after heating of the water in the water chamber is also prevented. And the heat is absorbed from the exhaust gas, and the saving of the energy is enabled by utilizing this heat for the heating energy in the hot air feeder. |
