<p>PURPOSE:To prevent ununiform flow from developing due to air bubbles and lead the air up to the upper layer of a tank without impairing the mixing inhibitory effect of a baffle plate by a structure wherein air passage holes, which surely remove the air inflowing through a feed water pipe, are provided on the baffle plate. CONSTITUTION:A means 4 to heat the water from the lower layer of a tank 1, a feed water pipe 6 to communicate with the lower layer of the tank and a delivery hot water pipe 7 to communicate with the upper layer of the tank are provided. A baffle plate 13 having a plurality of fluid passage holes 12, which are flush with or above the water outlet 8 of the feed water pipe 6, is arranged. At the same time, air passage holes 14, the area of each of which is larger than the area of each fluid pasage hole 12, are provided near the water outlet 8 of the baffle plate 13. Consequently, air bubbles blow from the water outlet 8 so as to pass through the air passage holes 14 in order to easily reach the upper layer portion of the tank without impairing the function of the baffle plate.</p> |
