Disclosed herein is a method of automatically cleaning boiler pipes. The provision of a pipe-cleaning tank on one side of a casing to store a cleaning solution therein and a tank supply valve in the pipe-cleaning tank allows 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.

The present invention provides a hot water storage-type boiler having both a heat amount proportional control function and a backflow prevention function to prevent a backflow of exhaust gas with a simple structure. In the present invention, since a check valve is integrally coupled to a burner duct, there is an effect of convenient assembly. In addition, since the check valve is built in the burner duct, the check valve does not protrude to the outside, thereby having an effect that a separate space is not required.

The present invention relates to an apparatus and method for detecting an earthquake using an accelerometer. More particularly, the present invention relates to an apparatus and method for detecting an earthquake using an accelerometer, the apparatus and method being capable of improving reliability of acceleration data obtained from the accelerometer and reliably determining whether an earthquake has occurred on the basis of a change between current acceleration data and previous acceleration data.

Apparatus and method for detecting earthquake using accelerometer

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.

Hot water boiler with vortex guide

The present invention relates to an instantaneous water heater having a guide part. The instantaneous water heater having the guide part is configured to allow direct water to stay around a heater for a long time, so that direct water is efficiently heated into hot water at a preset temperature desired by a user.

Instantaneous water heater having guide portion

The present invention relates to a boiler with a heating blower, the boiler being able to improve heat exchange efficiency without an additional boiler. According to the present invention, there is provided a heating blower that supplies high-temperature hot wind to a flame guide tube outside a storage tub, so it is possible to improve heat exchange efficiency of the flame guide tube and flue tube without an additional boiler.

A storage type electric water heater provides hot water and hot air. A large amount of hot water can be instantaneously tapped by a hot water generating means, and hot air can be generated by a hot air generating means.

Storage type electric water heater with hot air generating function

The present invention relates to a boiler having a gas sensing and an earthquake sensing function and a control method thereof, in which a gas leakage and an earthquake occurrence are automatically sensed and thus the boiler is forcibly stopped by causing fuel supply thereto to be cut off. The present invention is configured to cause fuel supply to the boiler to be cut off by comprehensively determining whether gas is leaking from the boiler and whether an earthquake has occurred at the present time, thereby minimizing loss of life due to the gas leakage and the earthquake occurrence.

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.

Hot water storage boiler having scale prevention function

The present invention relates to a combined heat and power system with an energy control module. The system can easily increase the temperature of waste heat generated by a power generator or can easily increase the temperature of recovered heat recovered to the power generator.
