A Shower in the Air Force: It’s all about function, not fashion.

A Shower in the Air Force: It’s all about function, not fashion.

When the Royal Australian Air Force wanted to save water, electricity and money, the obvious place to look was the amenities block. Why? Because that’s where soldiers, after a hard day defending us, go to relax in a long hot shower.

Trouble was, our men at arms really like long, long showers.. so shower timers were out of the question. So were flow controllers that choke off the strength of a shower, and misting showers that our men thought were for ..er.. lesser than 100% men.

That’s why after a long and intense tendering process, the RAAF chose e-Shower heads.

e-Shower’s inventor Richard West reckons he went through a thousand prototypes before he perfected the unique Venturi system in his e-Shower. It delivers nanobubbles of water in a  strong stream. They I like a water wasting shower.. but they save a whopping 70% of the water and the electricity it took to heat it.

The soldiers were happy and the bean counters were happy. The bean counters saved on the installation cost of extra heating systems to supply the demand of full flow showers. They also saved heaps on plumbing costs for all of the callouts the old overstressed heating system created. A real win-win.

But there was another big gain they didn’t even bargain on. The old full flow showers regularly blocked up with calcium accretion in the hard water of their army base. This meant constant maintenance and regular shower head replacement.

Here’s what the bean counters had to say:

“A showerhead which had been installed in the initial stages of energy management, has just been removed and tested for efficiency and calcification of the orifice and shower rose. No deposits of foreign matter were detected due to the aeration action of the E-Shower unit and efficiency standards have been maintained.
The utilisation of E-Shower showerheads will not only deliver the designed reduction in energy consumption, operating costs reduction and greenhouse emissions but also provide secondary quantifiable reductions.”

Richard attributes this amazing lack of calcium buildup to his high turbulence venturi system. Research now validates his theory, showing that high turbulence water will convert ‘sticky’ calcium carbonate to a different form of calcium known as Aragonite, which has a different ionic charge, meaning it not only doesn’t stick to metal and block shower rose holes, but it also slowly removes previous accretions. It’s like having a mini-cleaner installed – but it’s a totally natural process!
