Abstract: A storage type gas water heater has two or more tanks/areas providing a primary heated water storage area from which hot water is drawn, and one or more supplementary water storage areas utilizing hot combustion gas from the primary heated water storage area generating and supplying temperate water to previous supplementary water storage areas and/or the primary water storage area. An energy recovery chamber is situated between the primary heated water storage water area and the supplementary water storage area(s), with combustion gas vented therein. A hollow diffuser, defining a diffuser cavity, or one of various heat exchangers, is provided in the energy recovery chamber over the vented combustion gas. The diffuser cavity or heat exchanger receives temperate water from the supplemental water storage area and further heated by the vented combustion gas impinging the hollow diffuser or heat exchanger before being provided to the primary water storage area.

Abstract: A heating and hot-water supply device includes a combustion means, a heat exchanger, a circulation passage, a circulation means, a bypass passage, a distribution means, a hot-water supply heat exchanger, a water supply passage, a hot-water supply passage, and a control means. The heat exchanger heats a heating heat-medium to a target heat medium temperature. The distribution means distributes the heating heat-medium to the circulation passage and the bypass passage. The control means is capable of adjusting a distribution ratio of the distribution means to be adaptable to a heating operation, a hot-water supply operation, and a simultaneous heating and hot-water supply operation. At the time of transition from the heating operation to the simultaneous heating and hot-water supply operation, in a case where the heating terminal for performing heating is a warm air heater, the control means raises the target heat medium temperature.

Abstract: A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.

Abstract: A hot water supply system includes a hot water supply device which can be connected to an external communication network via a communication repeater, and a server. The server obtains, in pairing processing of associating a mobile terminal device which can remotely control the hot water supply device with the hot water supply device, identification information of a communication repeater to which the mobile terminal device is connected, and stores the identification information along with pairing information. Besides, the server performs control to determine conditions of the remote control based on whether the identification information of the communication repeater stored in association with the hot water supply device being a remote operation destination matches identification information of the communication repeater received from the mobile terminal device in the communication, when the communication of the remote control is received from the mobile terminal device.

Abstract: A heating and hot-water-supply apparatus is provided with: a control unit that performs control on the basis of detection parameters of a plurality of detection means installed at the aforementioned locations and a setting parameter set in an operation unit. The distribution means can adjust the distribution ratio so as to correspond to a heating operation, a hot-water supply operation, and the simultaneous heating and hot-water-supply operation. The control unit prohibits the simultaneous heating and hot-water-supply operation in a case in which the required heating capacity for the hot-water supply operation calculated on the basis of the detection parameters and the setting parameter is equal to or greater than a predetermined standard capacity.
