Abstract: 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.

Abstract: An instant hot water delivery system includes a thermal storage bin that receives hot water from a water heater via a hot water supply conduit and stores the hot water therein. The thermal storage bin is disposed adjacent a point of demand to deliver the hot water instantly to the point of demand responsive to a demand. The thermal storage bin is configured to retain a thermal energy of the hot water for a prolonged period using a phase change material. When the hot water stored in the thermal storage bin cools down below a threshold temperature, the cooled down hot water is recirculated to the water heater via a cold water supply conduit using a crossover valve. The recirculation is based on thermosiphon. Fresh hot water from the water heater replaces the cooled down hot water that is displaced from the thermal storage bin.
