<P>PROBLEM TO BE SOLVED: To provide a boiler device capable of stably feeding water and measuring a flow rate without reference to the amount of fed water when the water is supplied to a can body by a proportional control type pump. <P>SOLUTION: The boiler device includes a can body, a combustion part which heats the can body, a water feed unit which supplies water to the can body, and a control unit. The control unit has a continuous mode in which the water is fed continuously from the water feed unit when the amount of water fed from the water feed unit to the can body is larger than a threshold and an intermediate mode in which the water is intermittently fed from the water feed unit when the amount of water fed from the water feed unit to the can body is equal to or less than the threshold while the combustion part heats the can body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
