<p>The present invention relates to a boiler using a heat exchange capable of heating a heat exchange pipe by making combustion gas, which is generated inside an inner combustion chamber, flow through a gap between water tube pipes connected to the combustion chamber, reversely discharging the combustion gas passing through the water tube pipes by changing a flowing direction of the combustion gas by using a blocking boiler after passing through a gap between the blocking boiler and a connection heat exchange pipe formed on the upper side of the blocking boiler, and discharging the combustion gas to a waste gas outlet (17) after discharging the combustion gas while heating the internal and external parts of the double pipe to heat water inside the double pipe. The present invention is capable of using both of the water tube pipes and the double pipe and capable of using only the water tube pipes or the double pipe for the boiler, thereby selectively forming the boiler according to the purpose of use by using both of the water tube pipes and the double pipe. In addition, the present invention heats the water in a short time to produce hot water by making the water flow through each pipe and a gap between inner and outer pipes of the double pipe. The present invention is capable of adjusting the size and the height of the boiler by forming the boiler by using the multiple heat exchange pipes as one set and connecting the boilers using the multiple heat exchange pipes. Therefore, the present invention is capable of improving spatial utilization according to a place where the boiler is installed, reducing expenses and time required for fixing and repairing, replacing the boilers respectively when an electronic heater malfunctions, and obtaining an effect of preventing accidents by avoiding the risk of an electric shock and a short circuit.</p> |
