Abstract

A hot water supply and heating system 1a includes a heating flow rate changing valve 44 that changes the flow rate of hot water flowing through a heating pipe 46 and a priority controller 53a that carries out hot water supply priority control whereby to reduce the flow rate of the hot water flowing through the heating pipe 46 by the heating flow rate changing valve 44 in the case where the total of the amount of heat consumed in a heating operation and the amount of heat consumed in a hot water supply operation is equal to or more than a maximum amount of heat that can be applied by the heat source machine 10 during a simultaneous operation of the heating operation and the hot water supply operation.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a hot water supply and heating system that supplies hot water and performs heating by using hot water generated by heating with a heat source machine.

[0003] 2. Description of the Related Art

[0004] Conventionally, there has been proposed a hot water supply and heating system, which uses a heat source machine connected to a water supply pipe and a hot water supply pipe to heat water supplied from the water supply pipe and output hot water to the hot water supply pipe, and which is adapted to perform a heating operation for heating by using the hot water output to the hot water supply pipe from the heat source machine and to perform a hot water supply operation for supplying hot water to a hot water outlet tap connected to a downstream end of the hot water supply pipe (e.g. Japanese Patent Application Laid-Open No. 2008-82633).

[0005] The foregoing hot water supply and heating system is provide...
