Aerating Showers – Busting the Myths

Aerating Showers – Busting the Myths

Our blog post last month referred to an independent study that demonstrates the Kelda Technology Shower System is 20x safer than an aerating shower in guarding against harmful legionella when comparing the generation of aerosols which carry the legionella bacterium.

 

Not only are aerating showers a potential health hazard for commercial shower operators, there’s also a whiff of snake oil about them. Here’s our top reasons why when it comes to saving water and ensuring a decent shower experience, aerating showers just don’t cut the mustard:

 

1. Aerating showers are only suitable for high-flow mixer installations, applying to roughly 10% of UK housing stock which have above 8 litres per minute flow rate. Aerating showers do not work with electric showers or low flow mixers.

 

2. All known aerating showers simply restrict flow using flow restrictors to attempt to save water and energy.

 

3. Aerating showers restricts flow and aerate water to change spray ‘feel’.  Independent analysis has shown there is no measurable boost in performance.

 

4. Unlike the Kelda Technology Shower System, air is sucked in to aerate water.  Water pressure/flow is used to suck atmospheric air into flow through small venturi.  This disrupts the spray pattern as air escapes from spray plate but does not increase spray force.

 

5.  The Kelda Technology Shower System has an infinitely variable air boost control and water flow courtesy of the digital control module that drives our air module. Aerating showers have no control.
