Abstract (en)

Disclosed is a heating water flow circulation and hot sanitary water supply apparatus in a combi-boiler which preheats cold water during heating and instantaneously supplies hot water when turning a tap on for use in the kitchen and bath room, etc. The apparatus comprises a water-to-water heat exchanger, in which sanitary water layers and heating flow layers are alternately multilayer-formed to perform heat exchange between heating flow and sanitary water, and a heating flow diverting unit controls the five direction of the heating flow circulation according to a heating mode or a hot sanitary water supply mode. Also, the apparatus rapidly supplies the hot sanitary water by circulating part of the heating flow to the heating flow layers of the water-to-water heat exchanger during the supplied heating flow is circulated for heating. Accordingly, the heating water flow circulation and instantaneous hot water supply apparatus of the present invention can shorten a outflow time of cold water when using hot sanitary water and simplify many components in a boiler including a heating flow bypass valve, which is integrated in a single module. <IMAGE>
