The present invention relates to a boiler, and in particular, by selectively operating the external heating device and the internal heating device that is heated by electricity to heat the heat exchanger pipe in which the fluid (cold and hot water) flows into heating to generate no smoke at all. It will not pollute indoor or outdoor air.

In general, a boiler is a device that burns fuel such as gas, petroleum, and coal and transmits the heat of combustion to water to generate steam. The heating and hot water boilers used at home are divided into a gas boiler and an oil boiler according to the fuel used. Lose. Recently, gas boilers with low air pollution and ease of use are used, and liquefied natural gas (LPG) is mainly used as the fuel. The gas boiler is a gas supplied through the gas supply pipe is to be ignited through the main burner by the ignition transformer, the heat exchanger is installed inside the gas boiler, the rooftop tank or hot water circulation pump through the water supply and heating pipes. It is installed. By the way, the heat efficiency of the gas boiler is typically about 70% to 80%, and the remaining 20% to 25% is a loss due to the exhaust gas.

In addition, the gas boiler may be classified into various types according to the control method and the sealed state, but may be classified into condensing and non-condensing types according to heat sources for heating the heating water. The condensing gas boiler configuration is a downward combustion type in which gas moves downward to supply heat and an upward combustion type in which heat is supplied upward while moving upward.

However, such a conventional boiler uses gas and petroleum as fuel, so that smoke is generated and contaminates the air, and a communication and exhaust burner for releasing it must be provided. In the case of the complex, the use of petroleum as a fuel is not easy to store because of its large size, the high cost of heating in the high oil price era, the gas has a problem such as explosion and poisoning.
