GAS BOILER

摘要

PURPOSE: A gas boiler is provided to efficiently arrange a connecting position of each devices of the gas boiler, to reduce volume of the boiler by removing a copper pipe and to improve productivity by reducing a production cost. CONSTITUTION: A gas boiler comprises a cistern tank(101) storing heating water to reheat the heating water; a hot water supply heat exchanger(102) supplying hot water by heating water supplied from outside; a circulating pump(103) having a discharging pipe and a suction pipe to circulate the heating water in a heating pipe; a heat exchanger(104) supplying the heating water into the heating pipe by heating the heating water stored in the cistern tank; a three way valve(105) changing current of the heating water in using the hot water; and a hot water supply flowing switch(106) controlling the current of the hot water in supplying. Thereby, the gas boiler reduces volume of the boiler by removing a copper pipe. Moreover, the gas boiler improves productivity by reducing a production cost.
