A hot water faucet system can include a housing, an outlet, a heating chamber, a valve assembly, and a handle. The valve assembly can include a valve assembly inlet, a valve body, a flow selector, and a valve cap. A handle is connected to and can rotate the flow selector within the valve body. The valve body includes a valve body aperture and the flow selector includes a notch. As the handle is rotated from zero degrees to approximately 90 degrees, the alignment of the notch, the valve body aperture, and the valve assembly inlet increases so that the flow of water from the valve assembly inlet increases. As the handle is rotated from approximately 90 degrees to approximately 160 degrees, the alignment of the notch, the valve body aperture, and the valve assembly inlet decreases so that the flow of water from the valve assembly decreases.
