Abstract: The invention allows producing air flow to either inflate a self-making bedding system via a first outlet, or to heat the air exiting the apparatus via a second, optionally a third, outlet, for controlling the air flow and the temperature sent into the self-making bedding system. The 5 apparatus is operated via an interface on the outside surface of the apparatus; a smartphone or tablet, an intelligent virtual/personal assistant or a computer including an application or software for wirelessly sending instructions to the apparatus, e.g. using Bluetooth™ or Wifi; or a remote control. The invention is particularly useful for disabled persons for self-making their bed by directly controlling the apparatus via the application, with the possibility to use a 0 voice control system combined with the application, or to have the apparatus daily programmed for making the bed or controlling the temperature at specific time of the day.

Abstract: A water heater includes a tank defining an interior space adapted to contain water and a shroud over the water heater and defining a component space inside the shroud. A first pipe nipple is coupled to a spud of the water heater, the first pipe nipple and spud defining a non-collinear axis that is non-collinear with a pipe axis of a pipe to be fluidly connected to the tank. A flexible connector is connected at one end to the first pipe nipple along the non-collinear axis. A second end of the flexible connector is positioned collinear with the pipe axis. A second pipe nipple is coupled at one end to the second end of the flexible connector and coupled at an opposite end with the pipe. Fluid communication is established between the pipe and the interior space of the tank through the pipe nipple and flexible connector.

Abstract: The present invention discloses is a method for collecting a temperature of a heating pipeline, the method comprising: collecting a circuit signal of a heating resistor; calculating a current resistance value of the heating resistor according to the circuit signal; and calculating a current temperature of the heating pipeline according to the current resistance value. By using the method for collecting the temperature of the heating pipeline, measurement of the temperature of the heating pipeline can be realized by directly measuring the resistance value of the heating resistor in the heating pipeline, which may avoid the use of an additional temperature sensor, thereby reducing the number of connecting wires or other accessories.

Abstract: The disclosed technology includes a gas delivery system for controlling a target gas input rate of a fluid heating device. The system can include a sensor configured to measure a temperature of a gas flowing in a gas flow path, a modulating orifice in fluid communication with the gas flow path, and a motor in mechanical communication with the modulating orifice. The system can further include a controller configured to receive temperature data indicative of the temperature of the gas. The controller can determine a target cross-sectional area of the modulating orifice based at least in part on the target gas input rate and the temperature of the gas and, in response, output a signal to the motor to transition the modulating orifice from a first position to a second position having the target cross-sectional area.

Abstract: An integrated valve and flow sensor for a water heater can have a valve body that includes a valve and a flow sensor for measuring the flow of water through the valve. The integrated valve and flow sensor can be disposed within a fitting that can be attached to a water heater. An actuator for opening and closing the valve can be attached to the fitting. A diffuser can also be attached to the fitting.

Abstract: A dielectric fitting includes a nut having inner threads and an axial compression surface, and a hole having a first diameter. A mating component includes outer threads that engage with the inner threads including a second axial compression surface. A first fitting includes a circumferential flange captured between the first axial compression surface and the second axial compression surface, the first fitting having a first wall that extends axially and passes through the first hole and includes first fitting threads. A second fitting includes second fitting threads that engage with the first fitting threads, the second fitting having a second wall and a bulge portion that radially projects to a second diameter and includes an O-ring. The nut and the mating component are dielectrically isolated from the first fitting and the second fitting, and the second diameter is larger than the first diameter.

Abstract: A gas manifold allows each distribution chamber to be fed with fuel gas at an appropriate flow rate irrespective of an increase in the number of distribution chambers included in the gas manifold. A gas manifold distributes fuel gas flowing in through an inlet to a plurality of distribution chambers through a main channel. The main channel includes a flow guide that guides the fuel gas toward a maximum distribution chamber and reduces the fuel gas flowing into other distribution chambers. This allows fuel gas at a sufficient flow rate to be fed more easily to the maximum distribution chamber than to the other distribution chambers for a larger number of distribution chambers included in the gas manifold, allowing the plurality of distribution chambers to be fed with fuel gas at appropriate flow rates.

Abstract: In a heating and hot water supply apparatus, a heat exchanger for hot water supply includes a primary-side path and a secondary-side path. A bypass path branches from a heating circulation path and is configured such that a heat transfer medium heated by a heating device flows through the primary-side path without passing through a heating terminal when hot water supply operation is performed and then joins the heating circulation path again. A control unit controls a flow rate regulating valve so that a hot water flow rate does not exceed a reference limit flow rate when hot water supply operation is performed. The reference limit flow rate is set on the basis of the smaller one between a maximum heating capacity of the heating device and a heating capacity of the heating device at which an output temperature of the heated heat transfer medium reaches an upper limit temperature.

Abstract: In a heating heat-source apparatus having input circuits configured to receive pieces of mutually independent heating demand information, an abnormality related to an operation for setting one input circuit among the input circuits to a use state is detected and reported. Input circuits receive heating demand information. An operation part receives an operation for setting one input circuit of the input circuits to a use state. A CPU receives heating demand information transmitted from the input circuit in the use state while receiving specified information for specifying the input circuit in the use state from the operation part. Each piece of heating demand information is voltage information having a predetermined voltage range. The CPU reports an abnormality related to an operation for setting when voltage information transmitted from the input circuit in the use state deviate from a voltage range specified in the specified information.
