Abstract: A free standing dispersant film is provided, including: a partially hydrolyzed polyvinyl acetate; a poly(ethylene oxide); a polyalkylene glycol; a plasticizer; a dispersant polymer; optionally, a poly(isobutylene-co-maleic anhydride) copolymer, wherein the poly(isobutylene-co-maleic anhydride) copolymer is at least partially neutralized; and optionally, an optional additive.

Abstract: A water heater system includes a water heater having a first water outlet and a second water outlet. The water heater system further includes a flow detection device coupled to the first water outlet to detect a water flow through the first water outlet. The water heater system also includes a flow control valve fluidly coupled to the second water outlet. The flow control valve is configured to control a flow of water through the second water outlet based on whether the water flow through the first water outlet is detected by the flow detection device.

Abstract: A water heating system can include a first tank-based water heater having a first inlet line and a first outlet line, where the first inlet line provides unheated water to the first tank, and where the first outlet line draws heated water from the first tank. The system can also include a first tankless water heater having a second outlet line, where the second outlet line of the first tankless water heater provides the heated water to a first heated water demand. The system can also include a first valve that controls an amount of the unheated water flowing through the first inlet line to the first tank-based water heater. The system can further include a controller operatively coupled to the first valve, where the controller controls a position of the first valve based on the first heated water demand and a first capacity of the first tankless water heater.

Abstract: A water heater with a leak detection system includes a leak sensor assembly that is disposed in an insulation cavity between an inner storage tank and an outer protective jacket of the water heater. The leak sensor assembly is configured to detect water that leaks from the storage tank. Further, the water heater includes a barrier that is disposed in the insulation cavity and wrapped around the inner storage tank to channel the water that leaks from the storage tank towards the leak sensor assembly, and prevent the water that leaks from the storage tank from flowing through an insulation material that is disposed in the insulation cavity.

Abstract: A water heater monitoring and notification method includes determining, by a controller of a water heater system, a deviation of a duration of a pre-purge operation from a pre-purge duration average value. The method further includes determining, by the controller of the water heater system, a deviation of a flame current from a flame current average value and determining, by the controller of the water heater system, a deviation of a pulse-width-modulation (PWM) parameter from a PWM parameter average value. The method also includes providing a notification related to a combustion system of the water heater system based on at least the deviation of the duration of the pre-purge operation from the pre-purge duration average value, the deviation of the flame current from the flame current average value, and the deviation of the PWM parameter from the PWM parameter average value.

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.
