A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate, establishing a network connection between the mobile device and a server, transmitting information captured from the scannable feature by the mobile device to the server over the network connection, receiving from the server to the mobile device a plurality of water heater configurations in response to the information, receiving, with the mobile device, an input indicative of a configuration selection selected from the plurality of water heater configurations, and transmitting configuration information from the mobile device to the water heater to configure the water heater based on the configuration selection.

High intensity combustion and low intensity combustion are carried out together, to stabilize flames and to hold down the emission of carbon monoxide. An air-fuel mixture outlet member (back plate) that includes a single or a plurality of outlet(s) (air-fuel mixture outlet(s)) out of which an air-fuel mixture (GA) flows is include, and a metal fiber knitting body (metal knit) that covers the air-fuel mixture outlet member is included. Therefor, the air-fuel mixture, which is made to flow out of the outlet(s), passes through the metal fiber knitting body (metal knit) and is combusted, a flame of low intensity (flame) is generated together with a flame of high intensity (flame) by combustion of the air-fuel mixture, and the flame of low intensity holds the flame of high intensity.

A device that includes a pressure sensor that adds dynamic pressure sensing capability to a furnace. In some examples the device may include a relay and other circuitry to replace the single-setpoint pressure switch used to sense the operation of an inducer fan. The pressure sensor may measure the pressure from the inducer fan and send a signal to the other circuitry, such as a microcontroller. The other circuitry may determine when the pressure from the inducer fan reaches a predetermined threshold and allow the main gas valve of the furnace to open. The other circuitry may be configured to set the pressure sensor to a variety of predetermined pressure thresholds, and thereby replace multiple pressure switches. In some examples, the other circuitry may record pressure values received from the pressure sensor over time and provide performance data, as well as other signals or indicators.

An apparatus for managing hot water in a hot water storage tank heating system has one or more temperature sensors, a mounting bracket, a computer implemented processing arrangement configured to receive the temperature sensor signals and an interface to communicate with a user or additional processors either locally or remotely.

Dispensing of hot water having an adjustable temperature by way of a water outlet fitting that can be installed on a sink. This is achieved by a continuous flow heater and a measured value sensor arranged in a water inlet of the water outlet fitting as the hot water heater. The measured value sensor detects a measurement variable with regard to water flowing through the continuous flow heater (10). The water dispensing device has a control unit, which is designed to regulate a flow rate through the continuous flow heater as a function of measured values of the measured value sensor in order to adjust the temperature of the hot water.

The present invention relates to a sensor for measuring temperature of a fluid within a vessel, the vessel having a first region and a second region and the fluid having a temperature profile extending between the first region and the second region, the sensor comprising an array of elements, each element having a temperature-dependent parameter, the array being capable of deployment within or adjacent the vessel such that the array extends along the vessel for measuring the temperature profile, the elements of the array being coupled together between an input and an output, the input being coupled or capable of being coupled to a driving source for driving the sensors, and the output being coupled or capable of being coupled to a detector for measuring an aggregate of the temperature-dependent parameter from the array of elements. The invention further relates to a fluid temperature controller comprising a first input for receiving a first signal indicating a measurement of an aggregate of a temperature-dependent parameter from a sensor deployed within or adjacent a vessel containing a fluid having a temperature profile, a second input for receiving a second signal indicating a (preferably absolute) temperature of the fluid in the vessel and a processor configured to calculate a total thermal energy of the fluid in the vessel based on the first and second signals. The invention also relates to a combination comprising a sensing arrangement and a controller; a device; and a system.

A residential and commercial hot water and steam boiler safety system and device that includes at least one hollow pipe, with one plugged or sealed end and a fitting on the other end for connecting the pipe in a substantially vertical mounting position, and at least one two float switch disposed in the pipe and electrically connected in series with a limit switch in the boiler, where the pipe is adopted for the flow and accumulation of water, so that float switch activates as the pipe fills with water and shuts off the boiler by turning off the gas valve, promoting safer boiler and steam boiler operation. Additional float switches positioned above or below in the hollow pipe may provide additional functions, such as a warning light and sound to the owner, or a notification via a telephone or cell phone system or through the home network or Wi-Fi system.

A water heater may include a water tank, a burner, a pilot for igniting the burner, an ignitor for igniting the pilot, a thermoelectric device in thermal communication with a flame of the pilot, a controller for controlling an ignition sequence of the pilot using the ignitor, and a rechargeable power storage device for supplying power to the ignitor and the controller. The rechargeable power storage device may be rechargeable using the energy produced by the thermoelectric device. The controller is configured to selectively ran only the pilot for at least pan of a heating cycle to increase the recharge lime of the rechargeable power storage device while still healing the water in the water heater.

A water heater monitoring and notification method includes determining that an intake pressure switch of a combustion system of a water heater or an exhaust pressure switch of the combustion system of the water heater is open and shutting down a blower of the combustion system in response to the intake pressure switch or the exhaust pressure switch being open.
