The present invention relates to a heat exchanger of a hot water boiler having an excellent heat exchange efficiency, and more particularly to a heat exchanger using an electric heater and a sparking material as heating means. Not only can the general use of the apparatus be ensured but also the refrigerant fluid filled in the heating tank through the heating means is heated and vaporized and circulated to the heat exchange pipe to heat the heat exchange pipe and exchange heat with the water. The present invention relates to a heat exchanger of a hot water boiler which is excellent in energy use efficiency as well as possible.

Generally, a hot water boiler is a device that supplies hot water to the outside by forcedly discharging water that has been forced into a container through a pump through a heat exchanger after being pumped through a pump, and is widely used in houses, agricultural and livestock industries.

However, the conventional heat exchanger for a hot water boiler uses any one of heating means, which uses an ignition material such as an electric heater, coal, briquette and kerosene, as a heating means, so that when the supply of electricity or ignition material is stopped, There was a problem that it was difficult.

The conventional heat exchanger for a hot water boiler is configured to heat a heat exchanger pipe filled with water or distilled water through a heating means to circulate the heat to exchange heat with water in contact with the heat exchanger pipe, Since much time and energy are consumed to heat all the water filled in the heat exchange pipe at the time of initial operation, not only the supply of the hot water at the time of initial operation is slow, but also energy utilization efficiency is low.
