Water saving shower head
If you've still got one of those massive shower heads that wastes truck loads of water, then it's time for an upgrade. You can pick up a water saving shower head these days for as little as $20 from Bunnings and they're a cinch to install. Most of the time you can just unscrew the old water waisting shower head and screw on the fab new water saving shower head. So what's stopping you?
Old style inefficient showerheads can use as much as 20 to 30 litres of water every minute while a AAA rated water saving one will only use around 9 litres of water per minute. You won't just be saving water either, you'll save energy as you'll be heating less hot water.
Go on, go buy a water saving shower head now!
So how much will we save on this then? Waterwise as well as moneywise?
I think these water saving shower heads are a stupid idea. If we were dumb enough to waste all our water then we should suffer. NO WATER FOR ALL.
If you save 20 Litres a day, per person in your household, and let’s say you have (on avaerage) 3 people in your home, over a year you’d save around 22,000 Litres of water which equates to about $50 (based South East water’s pricing).
That would basically pay for your water saving shower head. Not a lot of money, but it’s more about the saving water. Imagine if every household did this.
There is also, of course, the energy saving as you’re not having to heat as much water for every shower. I’m not too sure how to calculate this cost – so if anyone has any ideas, let us know.
Shower science
Shower science: scientific research or empirical study to discover all the laws governing the operation and practical use of any showering system being domestic, commercial, military, aerospace, hybrid or other.
The practical laws that govern “extreme waste” in contemporary showers were perhaps radically investigated for the first time by Michael Vittorio Collalto who in the period during 1986 and particularly from 1994 onwards, set about materializing what has become one of the worlds first “hybrid shower” system.
Gradually incorporated as a research facility, the “hybrid shower” facility built over a period of twenty years was used to test the hypothesis amongst others that the domestic shower seemed to be no better than an efficient “cooling tower”, in disguise, that is amazingly adverse to the aim of providing a warm or hot showering environment.
(used to cool water in order to improve the efficiency of the refrigeration cycle in larger applications. e.g. commercial buildings.)

The problem has persisted that according to this discovery, although it is desirable to recover heat from any showering system and other systems like the kitchen sink, most of the thermal potential in thermally primitive showering systems is removed well before the water reaches the drain where any substantially meaningful recovery can occur.
Typically, most of the thermal energy is lost to the surrounding air and absorbed by various physical masses well before reaching the drain and is difficult if not impossible to recover. (Tiles, concrete shower base, glass, metal fixtures)
An environmentally catastrophic misunderstanding of the “shower science” that has thus far been involved, and continues to be pathologically connected to the attempts that are characterized, often quite vigorously with trying to improve the shower head.
A “water saving shower” can categorically, not, be elaborated unless also working on an “energy saving shower” as well.
After this, comparatively vast savings of water (and of course energy) occur because conversely, in a normal showering system of the primitive variety, those vast quantities of hot water are required to merely “replace” the loss of thermal potential that typically occurs throughout the shower enclosure.
Truly a disaster of “bad science” and very poor empirical scientific work resulting in very poor outcomes for global warming, and saving water and energy respectively

Heat exchanger technology is still very desirable for applications that are not subject to the considerable thermal losses occurring before the waste water reaches the drain. The kitchen sink for instance.
Other means can be used as a “first step” to optimize the shower to function hydraulically, thermally, and pneumatically, as efficiently as possible, and then heat exchanger technology is very desirable and should be employed to increase efficiency further still if resources or emissions are still a concern.
Combinations such as these are a very powerful, and ultimately deliver a better shower system!
