摘要： PROBLEM TO BE SOLVED: To perform a positive sensing of a reverse flow of discharged gas at a hot water generating equipment by a method wherein when a temperature of the discharged gas detected by a discharged gas temperature sensor placed at a non-operating side is more than a reference temperature under a state in which either a heating or a hot water feeding is being simply carried out, it is judged as an inverse-flow of the discharged gas. SOLUTION: A discharged gas pipe passage 1m of a hot water feeding side is provided with a discharged gas temperature sensor S1, and a discharged gas pipe passage 2h of a heating side is provided with a discharged gas temperature sensor S2. Operating state of each of hot water generating device at a hot water feeding side and a hot water generating device at a heating side is checked. When only the hot water generating device at the hot water feeding side is being simply operated, the discharged gas temperature at the heating side is detected by a discharged gas temperature sensor S2 so as to check if the discharged gas temperature is more than a discriminating reference temperature of the inversed flow of the discharged gas. When the discharged gas temperature is more than a reference temperature irrespective of the fact that only the hot water generating device at the hot water feeding side is being simply operated, it is judged that the discharged gas from the heat exchanger 1b at the hot water feeding side is reversely flowed to the hot water generating device at the heating side through either a discharged gas confluent box 1g or a discharging gas port of the gas supplying or discharging cylinder 1h. With such an arrangement as above, when the discharged gas is being reversely flowed to the hot water generating device, it can be positively detected.

摘要： PROBLEM TO BE SOLVED: To provide a heating and hot water feeding device in which a piping installation work against a gas feeding or discharging pipe can be easily performed and its outer appearance can be improved. SOLUTION: There are provided a gas feeding distribution box 1f and a discharged gas merging box 1g, thereby both gas feeding and gas discharging can be performed by one gas feeding or gas discharging cylinder 1h, a heating and hot water feeding device can be mounted only through the pipe installation work for the gas feeding or gas discharging cylinder 1h and at the same time the number of pipes to be installed can be reduced and its appearance can be improved. In addition, dampers d1, d2 for releasing only the gas feeding passage at an operation side are arranged within the gas feeding distribution box 1f and then when the hot water producing device placed at either the heating side or the hot water feeding side is operated independently, discharged gas flowed from the hot water generating device at the operation side can be prevented from being flowed back to the hot water producing device at non-operation side through the discharged gas merging box 1g.

摘要： PURPOSE:To obtain a warm water circuit system for preventing corrosion of a boiler and efficiently fusing snow. CONSTITUTION:A pump 12 and a first passage 151 of a heat exchanger 15 coupled in series with one another are coupled between a brine outlet 11a of a boiler 11 and a brine inlet 13a of a snow fusing radiator 13, and a second passage 152 of the exchanger 15 is coupled between a brine inlet 11b of the boiler 11 and a brine outlet 13b of the radiator 13. Brine directed from the boiler 11 toward the radiator 13 is heat exchanged with brine directed from the radiator 13 toward the boiler 11 in the exchanger 15. Thus, a temperature of the boiler 11 is not extremely lowered to prevent dew-condensation in the boiler 11, to prevent a trouble due to a low temperature corrosion and dew- condensation of the boiler 11 and to extend the life of a warm water circuit system.

摘要： PURPOSE:To prevent occurrence of trouble caused by mixing of air during subsequent heating operation by a method wherein a trial operation is carried out at a higher temperature level than the maximum heating temperature level and separation of air in circulating water is promoted. CONSTITUTION:A changing-over switch 19 is set to its trial operation side in order to perform a trial operation. An operation switch 15 is turned on, combustion is started and a water temperature is increased. As the water temperature increases up to an increasing temperature of 90 deg.C, the combustion is stopped. As the temperature is decreased down to a lower limit temperature 88 deg.C due to the stopped combustion, combustion is started again. The combustion and stopped combustion are repeated and a mean value of water temperature becomes about 89 deg.C. At this temperature, an amount of air resolved in water is a low value of 1% or less and the circulation water and air are sufficiently separated within a short period of time. During this trial operation, as a safety valve 7 is repeatedly opened or closed, the separated air is discharged. Upon completion of the trial operation, the changing-over switch 19 is returned to a setting of heating operation.

摘要： PROBLEM TO BE SOLVED: To simplify the circuit constitution regarding an impact detection, and perform the stop of burner combustion based on the impact detection under a high reliability. SOLUTION: Since one impact detector 17 is jointly owned by a control circuit 11 on the hot water supply side and a control circuit 12 on the heating side, and the circuit constitution can be simplified compared with a case wherein an impact detector is separately provided on the hot water supply side and the heating side, and the cost can be reduced as well. Also, even when both burners on the hot water side and the heating side are burning, the combustion, of both burners can be stopped by the same timing, based on the impact detection by the impact detector 17, and the reliability of the combustion stop can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a panel radiator on which a cover body can be simply fitted and which can output a relatively large power for the small size. SOLUTION: In a panel radiator 10 in which heatexchange pipes 12 set between a pair of headers 11a, 11b oppositely arranged are covered with heat- radiating bodies 15a, 15b from the front and rear sides and cover bodies 16a, 16b are attached to the radiating bodies 15a, 15b to cover respective headers 11a, 11b, since the heat radiating bodies 15a, 15b are extended to cover front and rear sides of respective headers 11a, 11b, these headers are hidden by the extended part 15e of the heat radiating bodies 15a, 15b. Further, the heat radiating space is widened by the extended part 15e and the height of the cover bodies 16a, 16b attached to the heat radiating bodies 15a, 15b is shortened as much as the length that the bodies are extended.

摘要： PROBLEM TO BE SOLVED: To provide a heating water heater for improving an external appearance by easily executing a piping of supply and exhaust pipes. SOLUTION: An air supply branch box 1f and an exhaust combining box 1g are respectively provided at a supply and exhaust cylinder 1h and a water heater unit 1. Thus, both air supply and exhaust can be conducted only by one cylinder 1h. The heating water heater can be installed only by executing piping of the cylinder 1h, and number of pipes to be executed for the piping is reduced to improve an external appearance. And, dampers d1, d2 for opening only an air supply passage of an operation side are provided in the box 1f. Thus, when a water heater of a heating side or hot water supplying side is solely operated, an exhaust gas from the water heater of the operation side is effectively prevented from being reversely supplied to the water heater of non-operating side via the box 1g.

摘要： PROBLEM TO BE SOLVED: To independently perform a heating and a hot water supply, and in addition, improve the loadability and the installability. SOLUTION: A hot water supply unit 1 for which a heating-exchanger (1b) for hot water supply, a burner (1c), a blower (1d), and a fuel pump (1e), etc., are housed in a box body (1a), and a heating unit 2 for which a heat-exchanger 2b for heating, a burner 2c, a blower 2d, and a fuel pump 2e, etc., are housed in a box body 2a, are respectively prepared, and the box bodies of both units 1, 2 are bonded to each other to constitute a heating-hot water supply device. Therefore, a hot water supply and a heating can be independently performed by using a hot water generating appliance of the hot water supply unit 1, and a hot water generating appliance of the heating unit 2 individually, and even when either one of the hot water generating appliances for hot water supply and heating fails, the hot water supply or the heating can be performed by making the other hot water generating function display normally.
