摘要： PROBLEM TO BE SOLVED: To perform operation such that a heat insulation function to insulate the heat of water in a heat exchanger to a value within a heat insulation temperature range in preparation for supply of hot water by effecting combustion of a burner in no water flow state is brought into an ON or an OFF state at a proper timing. SOLUTION: When some operation for variation of a set temperature and the like is effected by a remote control unit 60, it is estimated that this apparatus has a will to supply hot water and a heat insulation control part 51 brings a heat insulation function into an ON-state. Further, after preparation operation coping with the operation is completed, the heat insulation function is brought into an ON-state. For example, control for automatic operation is effected, after boiling of bath water, from a point of time when a bath is brought into a heat insulation state, the heat insulation function is brought into an ON-state. When a given time commencing from the starting of heat insulation operation elapses or given control is received, or based on detecting information of a given sensor, the heat insulation function is brought into an OFF state.

摘要： PROBLEM TO BE SOLVED: To accurately detect a circulation flow rate of a heat medium in a non-hot water supply side circulation path such as reheating circulation path. SOLUTION: When temperature detected by a temperature sensor 33 for hot water to be supplied by heat exchange exceeds OFF temperature, combustion with a burner is stopped by a single reheating operation combustion control section 45, and the combustion with the burner is restarted when it falls below ON temperature. The circulation flow rate of hot water of a reheating circulation path is detected by a reheating circulation flow rate detecting means 48, based on the temperature detected by the temperature sensor 33 for hot water to be supplied by heat exchange as varying with the burner combustion, a flow rate detection data previously applied and the temperature detected by a bath temperature sensor 37. The presence of supplied hot water leaked during the single reheating operation is judged by a leaked hot water supplied detecting section 49. When any leak of the supplied hot water is detected, the flow rate detected by the reheating circulation flow rate detecting means 48 during the single reheating operation before the detection of the leaked hot water supplied is decided as circulation flow rate of hot water in the reheating circulation path, by a reheating circulation flow rate deciding means 46.

摘要： PROBLEM TO BE SOLVED: To detect a flow rate in a reheating circulation passage without providing the reheating circulation passage with any flow rate sensor. SOLUTION: In a single boiler/two water feed pipe water heater which performs a heating by combustion with a burner common to a hot water supply heat exchanger and a rehating heat exchanger, temperature of hot water in the hot water supply heat exchanger is detected by a temperature sensor 31 for detecting the temperature of hot water to be supplied by heat exchange. During single operation of reheating, the combustion of a burner 5 is stopped when the temperature of the hot water to be supplied by heat exchange exceeds OFF temperature or the combustion is started when it falls below ON temperature. In this manner, the burner 5 performs an intermittent combustion. A circulation flow rate detecting section 34 detects the time t to the start of the subsequent combustion from the stopping of the combustion with the burner 5 by a time measuring means 33 and collates the detected time t1 and the temperature of a reheating circulation flow detected by a bath temperature sensor 21 with a data indicating a relationship with the time t1 the temperature of the circulation flow and the circulation flow rate applied in a data memory 35 to determine the circulation flow rate.

摘要： PROBLEM TO BE SOLVED: To provide a hot water supply unit in which a burner can be extinguished based on the temperature of hot water actually detected by a temperature sensor when the hot water in a heat exchanger is held at a temperature within a specified range before being delivered by burning a burner without conducting water. SOLUTION: A heat exchanger 30 is switched back at a part exposed from the side of casing thereof and a temperature sensor 44 is disposed at a part where the water tube arranged on the lowermost stage among water tubes 31a, 31b arranged on a plurality of stages is switched back. When a burner 20 is burnt without conducting water, temperature of hot water in the water tube 31a on the lower stage close to the burner 20 rises steeply depending on the amount of heating after firing. Consequently, the burner 20 can be extinguished based on the temperature detected by the temperature sensor 44.

摘要： PROBLEM TO BE SOLVED: To block a gas solenoid valve at the time of pilot firing control by opening a valve when water does not flow through a heat exchanger and isolating the valve forcibly at the time of combusting a burner. SOLUTION: When a flow rate sensor does not detect a flow rate of a specified level or above at the time of pilot firing control, a main valve 7 is required to be opened and the operation of a main valve interrupting circuit 61 is required to be disabled. The main valve interrupting circuit 61 is thereby connected, at the node thereof, with a Tr 3 for turning the main valve interrupting circuit 61 on/off. The transistor Tr 3 is applied, to the base terminal thereof, with a pilot firing signal S2 from a microcomputer 50. At the time of pilot firing control, an H level pilot firing signal S2 is fed to the transistor Tr 3 and the node has L level regardless of the level of an input voltage Vin. Consequently, a transistor Tr 2 is nonconducting at all times and when an H level main valve drive signal S1 is delivered to a transistor Tr 1, the transistor Tr 1 is conducted even if water does not flow through a heat exchanger and the main valve 7 is opened.

摘要： PROBLEM TO BE SOLVED: To prevent the discharging of high-temperature hot-water at hot-water supplying side due to independent operation of re-heating by a method wherein the increase of flow rate of hot-water, circulating through a re-heating circulation passage, and the temperature of off are set variably toward continuously and stepwisely increasing direction to set the temperature of off variably from the data of variable control of the flow rate of circulation of hot-water and the temperature of off. SOLUTION: A re-heating independent operation combustion control unit 45 detects a hot-water temperature in a hot-water supplying heat exchanger by a hot-water supplying heat exchanger hot-water temperature sensor 33 and compares the heat exchanger outlet side hot-water temperature with the temperature of off from the temperatures of on and off of a data storing unit 44 and the information of a re-heating independent operation monitoring unit 43. The re-heating independent operation is detected by the information of the monitoring unit 43 and when the hot-water temperature of the heat exchanger is decided that it is higher than the temperature of off, the combustion of a burner is stopped to stop the heating of the heat exchanger while the amount of heat of staying hot-water in the heat exchanger is reduced by the air supplying ventilation of a combustion fan. According to this method, the condition of staying hot-water, approached to boiling, is avoided whereby high-temperature hot-water discharging due to re-heating independent operation can be avoided.

摘要： PROBLEM TO BE SOLVED: To provide a hot-water supply burning equipment for effectively trans ferring to a normal hot-water operation from output hot-water temperature stabilizing control in starting hot-water supply. SOLUTION: When hot-water supply is started from the state that delayed water temperature rise occurs in a hot-water heat exchanger 1, valve openings of a first flow control means GM1 and second flow control means GM2 are controlled in a delayed water temperature rise eliminating direction to control a flow ratio of hot water side flow passing the means GM1 to mixing water amount passing the means GM2 to supply hot water in which the delayed water temperature rise is eliminated. When a difference of the hot water side flow to the total flow of the hot water side flow and mixing water amount becomes a set flow or less during the mixing operation, the means GM2 is stopped. It is prevented the means GM2 from remaining open, and transferred to a normal hot water supply operation state for performing maximum ability of the apparatus after the means GM2 is stopped.
