A faucet with a diverter is a device that combines two functions. Primarily, it functions as an electric heating faucet, which means it has a built-in heating element that can instantly heat flowing cold water. Thanks to this, it is not dependent on an external hot water source, such as a boiler. However, the key element of this type is the "diverter," which is a mechanical component, usually a lever or a rotary knob, that allows for changing the flow direction of the already heated water. In practice, this means that water can flow either through a standard spout, for example into a sink or washbasin, or the flow can be redirected to a second outlet after switching. This second outlet is most commonly a connection for a hand shower. This solution is used in places where it is necessary to serve both a sink and a shower head from a single water supply, typically in workshops, garden houses, or small bathrooms.
