<p>PURPOSE:To prevent a temperature of applied water from being decreased under a replenishing of water by a method wherein a boiler is comprised of a plurality of heating chambers having a heating means therein and arranged continuously in sequence, a water supplying port, a water discharging port and water passages alternatively arranged at either an upper part or a lower part of a heating chamber along a water flow direction CONSTITUTION:As a valve is opened, heated water is discharged out of a heating chamber 23 through a pipe in a direction of arrow E and then hot water is consumed, a liquid surface sensor detects a consumption of water and the cold water is fed into the heating chamber 20 in a direction of an arrow A. Water corresponding to an amount of fed water is sent in sequence in directions of arrows B, C and D through water passages disposed in each of the partitions 14 to 16 toward heating chambers 20 to 23 and then when a specified amount of water is detected by the liquid surface sensor in the heating chamber 23, the water feeding is stopped. Cold water supplied to the heating chamber 20 is not directly mixed with water of high temperature stored in the heating chamber 23, but water supplemented to the heating chamber 23 is a well-heated water in the heating chamber 22, so that the water in the heating chamber 23 does not drop its temperature rapidly and the water reaches to a predetermined temperature within a short period of time under a light supplemental heating.</p> |
