A water heater insert device positioned within an electrical showerhead or as a standalone liquids heating device. The water heater insert optimizes heat transfer by channeling water through a channel of a spiral or zigzag form where a deployed heating element supplies thermal energy. The channel maximizes water contact while minimizing the space. A temperature limiter adds protection against scalding.

The instant invention provides for a kit and method of raising inlet temperature of a water supply by utilizing thermodynamic properties associated with difference in temperatures across a gradient and friction. In particular a portion of an inlet supply pipe is disposed in a sewer line such that the opposing flow of waste water and related material interacts with the inlet piping by increasing the temperature thereof.

A sink system is provided. The sink system includes a sink basin and a discharge conduit coupled to the sink basin, which is positioned to expel fluid into the sink basin via an outlet thereof. The flow of fluid through the discharge conduit may be activated via a motion sensor or switch coupled directly to the basin or a spacer ring positioned between the basin and the countertop. Controls for adjusting the temperature and/or flow rate of fluid through the discharge conduit may also be coupled to the basin or a spacer ring positioned between the basin and the countertop, or alternatively, to a surface of the countertop. Methods of making and using sink systems are also provided.

There is proposed a water fitting having a fitting housing, having a water outlet commonly assigned to at least two water inlets, wherein at least two parallelly guided water lines are provided between one or more water inlets and the common water outlet, and wherein, in the parallelly guided water lines, there is provided in each case one control element for opening and closing the water flow path, which water fitting can be used in a flexible manner for the greatest possible number of sanitary applications, for example in kitchens, bathrooms, swimming facilities, sauna facilities, toilet facilities, abattoirs or the like, both in (semi-) public and also private areas. This is achieved according to the invention in that, when a control element in one of the parallel water lines is open, the one or more further control elements in the one or more further parallel water lines are closed.
