摘要： Provided is a hot water tank attached to a boiler. Water flows along a buffer tank as well as a hot water coil by providing the buffer tank and the hot water coil in an outer tank. Heat source applies heat water between the outer tank and the buffer tank while flowing therebetween. A significant amount of hot water IS supplied, and the temperature variation of the hot water is reduced.

摘要： Disclosed herein is a system for automatically cleaning boiler pipes, which includes a pipe-cleaning tank provided on one side of a casing to store a cleaning solution therein and a tank supply valve provided in the pipe-cleaning tank, so as to allow the cleaning solution stored in the pipe-cleaning tank to automatically flow into a heat exchanger and various pipes inside the casing by means of only a simple operation of manipulating the tank supply valve, thereby making it easy to eliminate scale that has accumulated in the heat exchanger and the pipes.

摘要： 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.
