<P>PROBLEM TO BE SOLVED: To provide a heat source machine for determining the use of other taps with high accuracy, while eliminating or reducing the influence of detection errors of a flow rate sensor or a temperature sensor. <P>SOLUTION: The heat source machine is provided with a heat exchanger, a water inlet pipe located in an upstream side of the heat exchanger, and a tapping pipe located in a downstream side of the heat exchanger to determine the use of other taps. The tapping pipe branches at least to a general hot-water supply pipe and an automatic bath filling pipe, and automatically supplies hot-water into a bath and supplies hot-water and cold-water to a general hot-water supply tap. At this time, the heat source machine acquires or calculates temperatures, flow rates, and heating values of hot-water and cold-water flowing through the water inlet pipe and the tapping pipe, and the automatic bath filling pipe, and calculates a ratio of the heating values of hot-water and cold-water flowing through the tapping pipe and the automatic bath filling pipe. Any of the heating value of the hot-water and cold-water flowing through the tapping pipe and the heating value of the hot-water and cold-water flowing through the automatic bath filling pipe is corrected based on the calculated ratio of the heating value. A value to be used for determining the use of other taps is calculated based on the corrected heating value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
