Abstract: A reverse combustion type combustion apparatus (1) includes a combustion section (2) that combusts fuel in a downward direction, heat exchangers (4, 5) disposed under the combustion section (2), and an exhaust box (6) disposed under the heat exchangers (4, 5). The exhaust box (6) is a molded product made from a synthetic resin material; the exhaust box (6) includes an opening portion (30) for introduction of combustion exhaust gases generated by an upper portion, a fixing portion (33) for fixing the heat exchanger (5), and an inclined bottom portion (35) that collects condensed water generated by the heat exchanger (5); and, at the lower end portion of the exhaust box (6), at least three legs (40) are integrally formed and make the exhaust box (6) stand up by itself.

Abstract: A process executed by a mobile communication terminal and water heaters and, which are capable of performing near field wireless communication, includes: a step in which the mobile communication terminal scans a BLE device (S215); a step in which a list of water heaters are displayed (S225); a step in which the mobile communication terminal generates connection data (S240); a step in which the mobile communication terminal transmits the connection data to the water heaters (S245); a step in which the water heaters receive the connection data (S250); a step in which the mobile communication terminal displays an operation screen for the water heater to which the connection has been completed (S285) when the connection data transmitted to the water heater and the input connection data match (YES in step S270); and a step in which the mobile communication terminal communicates with the water heater (S290).

Abstract: A hot water supply device 1 includes a fin-and-tube type heat exchanger (b 21) that applies heat to fresh water with combustion gases, and a heat exchanger casing (b 22) for housing the heat exchanger (b 21), and in order to be able reliably to determine by a simple method whether the hot water supply device is clogged by lime scale, there are provided a temperature detector (b 31) for detecting the surface temperature of the heat exchanger casing (b 22) and a control unit (b 7) that determines that scale has built up in the heat exchange tubing (b 27) of the heat exchanger (b 21) when the temperature detected by this temperature detector (b 31) is greater than a set temperature.
