Abstract

A heating and hot water supply system includes: a combustion means; a heat exchanger; a heating terminal; a circulation passage that connects the heat exchanger and the heating terminal; a circulation means; a bypass passage branched from the circulation passage and bypassing the heating terminal; a distribution means for distributing a heating medium to the circulation passage and the bypass passage; a hot water supply heat exchanger for the bypass passage; and a hot water supply passage; wherein the distribution means can adjust the distribution ratio so as to correspond to a heating operation, a hot water supply operation, and a simultaneous heating and hot water supply operation, and when the distribution ratio on the circulation passage side of the distribution means is smaller than a prescribed value during the simultaneous heating and hot water supply operation, the blowing operation of the blower at the heating terminal is prohibited.
