Abstract

A hot-water storage type boiler having a vortex guide portion is proposed. Since the present invention includes a spiral portion inside a casing, water supplied into the casing is moved to the upper side of the space part, while being in contact with fire tubes for a long time by moving spirally along the spiral portion, thereby improving heat exchange efficiency of the fire tubes. In addition, since the water supplied into the casing is moved spirally along the spiral portion to form a vortex, the flow of water moving in the direction of a hot-water discharge portion collides with a firebox lower surface part at a high speed, thereby having an effect of preventing scale from accumulating on the firebox lower surface part.
