In this case, the blowing device is operated to the maximum extent, and the combustion smoke generated in the combustion chamber 20 is easily discharged to the outside, so that the risk of explosion due to flammable smoke can be reduced.

Since the combustion smoke is generated when the combustion material is incompletely combusted, the combustion chamber temperature regulator 25 operates the blower until the combustion material reaches a temperature at which the combustion material can sufficiently combust, so that the combustion material is completely burned The generation of combustion smoke is suppressed to the maximum.

Here, the combustion chamber temperature regulating unit 25 can be operated under the control of the controller 80.

The exhaust and hot water generator 40 exhausts the combustion smoke to the outside and generates hot water by combustion heat generated by combustion of the combustion material.

A large amount of combustion smoke is generated due to incomplete combustion at the initial stage of ignition. Therefore, the controller 80 controls the combustion chamber temperature regulator (not shown) so that the temperature of the combustion chamber 20 is quickly reached to a temperature 25). .

The control unit 80 controls the operation of the combustion chamber temperature regulating unit 25 to be stopped when the temperature of the combustion chamber 20 reaches a temperature at which the combustion smoke does not sufficiently occur (about 380 ° C).

In addition, the controller 80 controls the hot water temperature of the hot water tank 50 to be faster than a predetermined temperature, and controls the hot water to be supplied to the outside when the temperature of the hot water reaches a predetermined temperature or more.

For example, when the temperature of the hot water is below a predetermined temperature, the controller 80 controls the combustion chamber temperature controller 25 to control the temperature of the combustion chamber 20 to rise so as to increase the temperature of the hot water. The hot water in the hot water tank 50 is controlled to be discharged to the outside through the hot water supplying lake connecting portion 56 by using a circulation pump or the like.
