PROBLEM TO BE SOLVED: To provide a heat source device capable of preventing a liquid from boiling in a heat exchanger for liquid heating without reference to heating devices such as connected hot water mats etc., and a number thereof.SOLUTION: In a liquid circulation passage for circulating a liquid through driving of a liquid circulation pump, the passage on a discharge side of the liquid circulation pump is branched, one thereof is a passage for introducing the liquid in the liquid circulation passage on a heat exchanger side for heating the liquid, and the another is a heating-side liquid supply passage for supplying the liquid to the heating devices such as hot water mats to be connected to the liquid circulation passage. The heating-side liquid supply passage is provided with a liquid flow rate control means 2 of controlling a flow rate of the liquid to be supplied to one or more heating devices to be connected thereto. A liquid boiling suppressing means 3 controls the liquid flow rate control means 2 to adjust the flow rate of the liquid to be supplied to the heating devices, and consequently, the flow rate of the liquid to be introduced into the passage on the heat exchanger side from a liquid circulation pump 6 is adjusted to prevent the liquid in the heat exchanger from boiling. |
