Abstract
The present invention relates to a hot water storage boiler having a scale prevention function, the boiler being able to prevent scale without an additive or an ultrasonic device. Low-temperature water is sprayed toward the bottom portion of the combustion chamber using the spray pipe. This consequently lowers the temperature of the bottom portion of the combustion chamber, thereby reducing production of scale.
