1.3.10 Installation of low-flow showerheads


One of the solutions to save water and energy consists of the placement of an aerator at the exit of the showerheads. These devices are screwed into the output of the showerhead, reducing the flow of water and they are compatible with most showerheads since they are available in different sizes and different types of thread.


  • Easy to install

  • Energy saving due to pumping (around 50%) and the derivative of the water heating (around 30%)

  • Anti-calcareous and do not become clogged

  • The use of low-flow showerheads allows 50% of water savings


  • Occupant acceptance

  • Operation and Maintenance (O&M) staff size, skill level, and budget need to be considered

Economic assessment

Initial investment: low. 4 € per low-flow showerhead
