| 摘要 |
The present invention relates to a boiler which simultaneously performs heat exchange between heating water and hot water and waste heat recovery to reduce fuel consumption, prevents heat loss in heated pipe water, secures stability in use by a pressureless operation method, and improves space efficiency. According to the present invention, the boiler comprises: a boiler body to heat water using combustion heat combusted by a combustion device; a heat exchange unit positioned on an upper portion of the boiler body and connected to the combustion device to receive waste heat combusted by the combustion device to heat supply water supplied from the outside to supply heated water as heating water or hot water; and a convection unit which is connected and installed in the boiler body and the heat exchange unit, and convects the heated water of the boiler body. |
