PURPOSE: A hot water boiler with a three-phase motor is provided to reduce noise, and to generate eco-friendly thermal energy with a simple structure. CONSTITUTION: A hot water boiler comprises a three-phase motor, first to third heat exchange chambers(50.51,52), and a damper(100). The three-phase motor is driven by AC(Alternating Current) power. The first, second and third heat exchange chambers comprise first to third heated hot water discharge passages(50a,51a,52a) and first to third heat generating fans(50b,51b,52b). The first, second and third heat exchange chambers are rotated by a shaft(30), and heat the water. The heated water is discharged through the first to third heated hot water discharge passages, respectively. The damper is installed in a feedback pipe(53b), and adjusts the feedback amount of the heated hot water. The damper feedbacks the hot water and circulation water to the first heat exchange chamber according to a pump(90) so that the circulation water in a second water discharge pipe and the water heated in the third heat exchange chamber are heated again. |
