<P>PROBLEM TO BE SOLVED: To provide a hot-water supply gas usage diagnostic system which measures exact gas usage without changing piping by including a flowmeter as an adapter at a faucet of the existing gas hot-water heater, and measuring temperature of hot-water supply to calculate the gas usage to be consumed by the gas hot-water heater by calculation. <P>SOLUTION: A hot-water supply gas usage diagnostic system 50 is constituted by including: a water supply temperature sensor 3 which detects temperature of water to be supplied to a gas hot-water heater 4; a hot-water supply temperature sensor 5 which detects temperature of hot water to be supplied by the gas hot-water heater 4; a flow sensor 10 which detects a hot-water supply amount from the gas hot-water heater 4; and a control part 9 which calculates the gas usage used by the gas hot-water heater 4 on the basis of water supply temperature data 10 detected by the water supply temperature sensor 3, hot-water supply temperature data 11 detected by the hot-water supply temperature sensor 5, flow data 12 detected by the flow sensor 10, and total gas usage data 13 acquired from a gas meter 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
