Abstract
The disclosure provides a heating and hot water supply apparatus which includes a heating circulation path configured to circulate a heated heating medium with a heating terminal, and a bypass path branched from the heating circulation path for causing the heating medium to flow therethrough without passing through the heating terminal. A hot water supply heat exchanger is disposed in the bypass path. A division ratio of the heating medium from the heating circulation path to the bypass path is controlled by a distribution valve. The division ratio is increased from a first value to a second value when a reservation preheat control is started during the heating operation according to a start reservation time of hot water supply operation reserved by a timer, and set to a third value greater than the second value during a simultaneous operation of the hot water supply and the heating operation.
