Provided is an apparatus for automatically controlling a constant flow by considering a heating load in which a necessary request heat amount necessary for optimum heating is calculated by considering a heating load per room to find a optimum flow in proportion to the heat amount and reduce a total constant flow of the household by the optimum flow corresponding to the heating-stopped room, and thereby to save fuel cost in proportion to the heating-stopped flow and decrease tube noise due to cavitation. |
