A system and approach for developing a periodic water usage profile and demand for controlling a water heater. A mode may be selected for demand for a certain amount of water of a particular temperature range to be available for use from the water heater. Data on hot water usage may be collected and the usage profile and demand may be calculated from the data. The water heater may be programmed to operate in a certain fashion based on the usage profile and demand. A control knob may be on the water heater control to select a particular demand. Control of the water heater may be operated from a remote device connected in a wireless or wired fashion. An optimization program may be implemented in the control of the water heater for achieving one or more beneficial goals related to water heater performance and hot water production.

A water heating assembly, related kit, use and method make use of a temperature control near a point of use of water, so as to reduce a time response for hot water at this point of use are provided. The water heating assembly includes a tank for containing water, an inlet temperature sensor for sensing an inlet temperature of the water upstream of the tank, and a valve located upstream of the tank. The valve is actuated when the sensed inlet temperature reaches a given temperature set-point such that the water is bypassed from the tank and directly sent to the point of use. The water heating assembly is configured such that the point of use can be fed with water at the desired temperature in a reduced time, the water coming directly from the hot water source and/or the water heating assembly, thereby saving water, energy and time.

In an electric water heater having adjustable set point and differential temperatures, upper and lower heating elements, and associated temperature sensors respectively operative to sense upper and lower tank water temperatures, a specially designed control system is provided for controlling the heating elements. The control system is operative to prevent dry firing of the heating elements by measuring temperatures over time with the temperature sensors.

A fluid discharge event detection apparatus measures a change in capacitance to detect the presence of a fluid in a sensing conduit where the presence of fluid indicates a discharge event. The apparatus includes a first conduit, the sensing conduit and a control valve, coupled between the first conduit and the sensing conduit. The control valve is configured to activate and fluidly couple the first conduit and the sensing conduit to one another when the control valve detects at least one predetermined condition of a fluid within the first conduit. A sensor, configured to measure a capacitance value, is disposed about the sensing conduit. A controller, coupled to the sensor, is configured to detect a change in the sensing conduit capacitance value and assert an alarm condition upon detection of the change in the sensing conduit capacitance value.

The disclosed technology includes a non-powered valve assembly having a valve, an actuating system, and a trigger. The trigger can be in mechanical communication with the actuating system and the actuating system can be in mechanical communication with the valve. The trigger can be positioned such that the trigger can interact with liquid resulting from a leak in a plumbing assembly. Upon interaction with liquid, the trigger can dissolve or expand, causing the actuating system to be activated and the valve to transition from the open position to a closed position. In the closed position, the valve can restrict the passage of liquid through the plumbing assembly such that the leak can be mitigated.

A tank water heater assembly is provided including a tank water heater and a drain pan provided with a sensor holder for mounting a sensor. The sensor holder accommodates a leak detection sensor at predefined distance above an inner surface of a bottom wall of the drain pan. In this way the presence of harmless small amounts of water in the drain pan do not trigger an alarm. A transport assembly is presented for facilitating transportation of the tank water heater assembly to an installation site and subsequent installation. Finally, a method for installation of a tank water heater assembly is provided.

An electric clip, such as may be utilized with a leak detector, has a base which receives an insert to secure an inserted material, such as a mesh, there between. The insert has an arm with opposing hooks which pass through a first slot in a biased manner and then spring out once through to provide an assembled configuration. The clip can be secured to the material, such as by directing fingers through a second slot in a biased manner which then return once through to retain on a ledge.

An indicator generating method for generating an indicator which is suitable for maintenance prediction of a water heating system is proposed. A power state indication device generates a high power consumption signal if a heating device of the water heating system is activated. The time duration of the activation is such an indicator, if no water flow is present. Furthermore, the time interval between subsequent activations is such an indicator. A predictive maintenance method processes these condition-based indicators and determines a remaining useful lifetime according to a predictive maintenance model. The predictive maintenance device outputs a maintenance signal indicating required maintenance, if the remaining useful lifetime drops below a predetermined threshold. The methods may be performed by water heating systems or beverage makers.

The invention relates to an arrangement for detecting and locating a leakage in a water pipe system, having a water treatment system, having a pump, having a supply line and a drain, having at least one circulation line connected to the supply line and the drain, having at least one inlet valve, at least one outlet valve and at least one pressure sensor in at least one circulation line and/or the supply line and the drain, wherein the inlet valve and the outlet valve are electrically controllable, having control means for controlling the inlet valves and the outlet valves, having detection means for detecting the timewise development of the measured values of the at least one pressure sensor, with evaluation means for evaluating the timewise development of the pressure change and for comparing the amount of the pressure change with a limit value, and with output means for the output of a leakage indicating indication signal if the amount of the pressure change exceeds the limit value. This arrangement solves the technical problem of improving the detection and, if necessary, location of a leakage.
