The disclosed technology includes a fluid heating device that can include a heating chamber in communication with a heating element, and an ultrasonic transducer in communication with the heating chamber and for transmitting ultrasonic sound waves. The disclosed technology includes an ultrasonic transducer system that includes an assembly configured to attach to a fluid heating device, and an ultrasonic transducer affixed to the assembly. The disclosed technology also includes a method for ultrasonic cleaning within a fluid heating device that can include a controller configured to receive flow data from a flow sensor; based on the flow data, determine that fluid is flowing through a heating chamber; and output instructions for an ultrasonic transducer to output ultrasonic sound waves.

The present disclosure includes arrangements, systems, and methods for removing mineral deposits. Disclosed is an aqueous solution within a container, with the container containing mineral deposits. The aqueous solution submerges the mineral deposits and may include at least one acid, or a combination of an organic acid and an inorganic acid in percentages that allow the replacement of toxic dangerous chemical ingredients. Disclosed also is a cathode and an anode within the container that are at least partially submerged within the aqueous solution. A direct current power source is configured to direct a voltage across the cathode and the anode to generate an electrical charge gradient within the aqueous solution.

An isolation valve including a main body including a fluid passage, a first port connected to the fluid passage, a second port connected to the fluid passage, a third port including an openable and closable valve, the valve connecting the third port to the fluid passage, and a plug removably coupled to the second port.

A drain valve comprising a body, an inlet for fluid to enter the drain valve, an outlet for fluid to exit the drain valve, a piston member having a piston head and a piston shaft, a seat against which the piston head seats in a closed condition of the drain valve, and a rotatable member that is rotatable relative to the body. The rotatable member is rotatably retained with the piston shaft, such that rotation of the rotatable member in one direction causes the piston member to move in a first linear direction away from the inlet such that the valve head is unseated from the seat to open the drain valve and, in use, allow fluid to enter the drain valve via the inlet and discharge via the outlet. Rotation of the rotatable member in the opposite direction causes the piston member to move in a second linear direction toward the inlet to seat the valve head on the valve seat to close the drain valve and, in use, prevent fluid from entering the drain valve via the inlet.

A tankless water heater including a water inlet, a water outlet, a conductivity sensor, a temperature sensor, and a heating chamber connected to the water inlet and the water outlet wherein the heating chamber is configured to heat a flow of water received from the water inlet and output the flow of water to the water outlet. The water heating system can further include a controller communicably coupled to the conductivity sensor and the temperature sensor, where the controller calculates an adjusted conductivity of a flow of water through the water heater.

A tamper-proof fluid sediment trap including a central body portion having a central longitudinal axis, an outlet leg portion, a drip leg portion, and a supply leg portion. The outlet leg portion extends upward from the central body portion parallel to the central longitudinal axis and is configured to operably couple to an appliance. The drip leg portion extends downward from the central body portion and defines a shape being resistant to threading or tapping of an outer surface or an inner surface of the drip leg portion. The supply leg portion is configured to couple to a fluid supply line, extends radially outward from the central body portion, between the outlet leg portion and the drip leg portion, and has a central longitudinal axis extending perpendicular to the central longitudinal axis of the central body portion. The portions of the tamper-proof fluid sediment trap are monolithically formed.

An isolation valve including a main body including a fluid passage, a first port connected to the fluid passage, a second port connected to the fluid passage, a third port including an openable and closable valve, the valve connecting the third port to the fluid passage, and a plug removably coupled to the second port.

Improved steamblow commissioning of a steam plant with steam discharged to the condenser and increased use of permanent piping instead of temporary piping with quenching/desuperheating and providing a low back pressure environment to enable aggressive steam blow cleaning.

The present disclosure includes arrangements, systems, and methods for removing mineral deposits. Disclosed is an aqueous solution within a container, with the container containing mineral deposits. The aqueous solution submerges the mineral deposits and may include at least one acid, or a combination of an organic acid and an inorganic acid in percentages that allow the replacement of toxic dangerous chemical ingredients. Disclosed also is a cathode and an anode within the container that are at least partially submerged within the aqueous solution. A direct current power source is configured to direct a voltage across the cathode and the anode to generate an electrical charge gradient within the aqueous solution.

An automatically flushing water heater maintenance system may be provided, the system including a water heater and a water heater controller. The water heater may include an inlet, an outlet, and a flush outlet having a first control valve in flow communication therewith. The first control valve may be configured to control a flow of water and sediment through the flush outlet out of the water heater. The water heater controller may be configured to communicate with the first control valve by transmitting a first control signal to the first control valve, the first control signal configured to cause the first control valve to open or close as part of an automatic flushing process. As a result of the flushing, the useful life of the water heater may be extended, and/or water heater leakage alleviated. Insurance discounts may be provided based upon using the automatic water heater flushing functionality.
