Water saving shower

from Wikipedia, the free encyclopedia

Water saving showers are shower heads that can lead to less water consumption when showering . With water-saving showers, the water flow rate is reduced, but at the same time an attempt is made to hide this reduction by adding ambient air. Water-saving showers reduce the energy consumption for heating the shower water due to the reduced water flow rate .

advantages

  • Emissions that occur when the water is heated are reduced.
  • The consumption of the resource water is reduced.
  • Significant cost savings are possible with the use of water saving showers.

disadvantage

  • Partly stronger fogging in the bathroom due to water vapor (depending on the model)
  • Slightly louder noise when showering

Structure and functionality

Jet shower

With this technique the water accelerates to a very high degree without atomization due to the geometry. First the water is fed through a nozzle. This water pushes through the shower head with the air it contains. The water then flows through the jet disc. A vacuum is created for milliseconds, which chops off the resulting water droplets. The negative pressure is too great and the shower draws in air again. This is a cycle that repeats itself over and over again. The resulting jet pattern is characterized by a slight pulsation and large droplets. The high water acceleration and the vacuum impulses are intended to counteract the formation of limescale.

Vortex chamber technology

This type of shower head traps a small air bubble in the water droplets . The drops appear larger and the shower jet full, even with a low water flow. The water is passed through a vortex chamber. This vortex chamber creates a rapidly rotating water vortex in the shower head through the incoming water. The suction effect of the vortex sucks air into the shower head. Water and air are mixed in the vortex to form a foam. This foam then emerges from the shower holes in the form of water bubbles.

Nozzle technology

Here, water is passed through one or more nozzles, accelerated and finely distributed. This creates a feeling of greater volume and leads to a slight massage effect when showering. At the same time, however, the drops are greatly reduced in size, resulting in increased splashing and fogging of the panes.

Flow reducer

Closely related to water saving showers are simple flow reducers. These are components that narrow the pipe cross-section and thereby reduce the flow rate. However, since no measures are taken to conceal this reduction, a flow reducer leads to a weak shower jet.
