Abstract
A heating and hot-water supply device includes a combustion means, a heat exchanger, a circulation passage, a circulation means, a bypass passage, a distribution means, a hot-water supply heat exchanger, a water supply passage, a hot-water supply passage, and a control means. The heat exchanger heats a heating heat-medium to a target heat medium temperature. The distribution means distributes the heating heat-medium to the circulation passage and the bypass passage. The control means is capable of adjusting a distribution ratio of the distribution means to be adaptable to a heating operation, a hot-water supply operation, and a simultaneous heating and hot-water supply operation. At the time of transition from the heating operation to the simultaneous heating and hot-water supply operation, in a case where the heating terminal for performing heating is a warm air heater, the control means raises the target heat medium temperature.
