BOILER CAPABLE OF STABLY SUPPLYING WARM WATER

摘要

A boiler capable of stably supplying warm water according to the present invention comprises a main heat exchanger which heats heating water by using combustion heat of a burner; and a hot-water supply heat exchanger which supplies warm water through heat-exchanging between heating water heated in the main heat exchanger and direct water, wherein the boiler comprises: a flow control valve which is provided at a direct-water supply pipe to allow direct water to be supplied to the hot-water supply heat exchanger, so as to control the flow rate of direct water supplied thereto; a mixing valve which is provided at a direct-water mixing pipe, so as to mix warm water, having passed through the hot-water supply heat exchanger, with direct water, wherein the direct-water mixing pipe is branched from the direct-water supply pipe and is connected to another direct-water supply pipe through which warm water heated through heat-exchanging with heating water in the hot-water supply heat exchanger passes; and a direct-water/warm-water water-pipe module which provides fluid channels of direct water and warm water, and a fluid channel of direct water mixed with the warm water, the fluid channels passing through the hot-water supply heat exchanger.
