The disclosed technology includes an on-demand water heater which uses a heat pump to heat the fluid. The on-demand heat pump water heater can have a low fluid capacity heating chamber which has an inlet and an outlet, a heat pump for heating the fluid, and a controller to control the heat pump and maintain the temperature of the fluid at a predetermined temperature. The on-demand heat pump water heater can include one or more temperature sensors, flow sensors, fluid mixing valves, or supplemental heat sources.

On-demand heat pump water heater

The disclosed technology includes an on-demand water heater which uses an electric heat source to heat the water. The on-demand water heater can have a low fluid capacity heating chamber which has an inlet and an outlet, an electric heat source for heating the water, and a controller to control the electric heat source and maintain the temperature of the water at a predetermined temperature setting. The on-demand water heater can be powered by a direct current power source. The on-demand water heater can also utilize a solar thermal system to provide additional heat to the water.

Direct current electric on-demand water heater

The disclosed technology includes a hose nozzle assembly with apertures sized to facilitate heating groundwater based on the expected temperature of the groundwater. The hose nozzle assembly can have a handheld enclosure having a handle portion connected to a body portion, a heating chamber having a heating element configured to heat a fluid, and a spray nozzle. The spray nozzle can include a first aperture configured to provide a first spray pattern at a first flow rate corresponding to a first change in temperature of fluid flowing through the heating chamber and a second aperture configured to provide a second spray pattern at a second flow rate corresponding to a second change in temperature of fluid flowing through the heating chamber. The second flow rate can be less than the first flow rate and the second change in temperature can be greater than the first change in temperature.

Heated hose nozzle

The disclosed technology includes a liquid storage tank having a heating element, an inlet for receiving unheated liquid, an outlet for outputting heated liquid, and a partition configured to divide the tank into a first portion and a second portion. The partition can have an aperture such that the first portion and the second portion are in fluid communication. The liquid storage tank can include an actuator in mechanical communication with the partition and configured to linearly move at least a portion of the partition based at least in part on the temperature of liquid within the tank.

Water tank with thermally insulating partition

A tankless electric water heater system including a heating chamber having an inlet at a first end and an outlet at a second end, a heating element connected to the heating chamber, a first temperature sensor disposed near the first end of the heating chamber, a second temperature sensor disposed near the second end of the heating chamber, a flow sensor configured to detect a flow of water and disposed near the heating chamber, and a controller connected to the first and second temperature sensors, the flow sensor, and the heating element. The controller is configured to have a set point temperature, to detect temperature and flow data from the first and second temperature sensors, and the flow sensor, and to provide as output a power setting to the heating element.

Tankless electric water heater

A heating unit for heating fluid is described having at least one electrical resistance heating element on an outer surface of a tube. At least one indexed groove is provided around a surface of the tube allowing for at least one retention clip to hold the electrical resistance heating element. A heating chamber is also provided to enclose a portion of the tube and to provide a flow channel therebetween. The heating chamber includes an optical sensor to detect overheating of the at least one electrical resistance heating element. Fluid is heated by flowing over the surface of the at least one electrical resistance heating element and through the tube.

Next generation bare wire water heater

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.

Systems and methods for preventing and removing chemical deposits in a fluid heating device

A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.

The disclosed technology includes a cleaning device for cleaning personal care tools, such as toothbrushes and shaving razors. The cleaning device can include a heating element configured to heat cleaning fluid received by the cleaning device and a high pressure nozzle configured to output heated cleaning fluid into the cleaning chamber.

Cleaning devices for personal care tools

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.

Valve assemblies for leak prevention

The disclosed technology includes a portable hand washing station having a sink with an atomizing nozzle that can provide an ultra-low flow of atomized liquid. The atomizing nozzle can reduce consumption of water and reduce the required supply of power for adequate operation of a heating device and a pump of the portable hand washing station. The heating device can include insulation, such that the heating device can provide heated water during an extended operation period.
