What Am I? Mystery Object.

[thor]

One thing I forgot to mention is that these shower heads have no on-off switch. You just open the cold water faucet and the water heats as it passes through the electrical resistance held in the head. When you finish showering you just close the faucet and the showerhead disconnects itself.

The passing water acts as a conductor and closes an otherwise "open" electrical switch? A pressure switch? I guess the first option is more plausible, these are very simple devices.

Controls on Broad Side.. It was a very cheaply built complex, also imho i think that ones behind could turn the water off very easy. The reason i think:
Its cheper. One hot water line run straight and one cold water line run straight. Plus if everyone on that "block" or "tower" uses a single gas fired water heater (which is very common here and in some citys like detroit) than thats a major savings not having to use mult. water heaters, etc.

My new apartment has its own little 30 gallon hot water tank, which is uncommon here, and its something i really love.

shower heads

Well normally you do not install TWO shower heads of course!!
We had only one and that was nice.
It is a tankless water heater installed in the shower head and with a pressure switch it switches itself on and off.
Usually theres also a switch for the plug arround - mostly at the wall in or outside the bathroom or next to the socket like in the UK. But these showers have a switch too! It switches from summer to winter setting (half and full heat).
But the one I wanted wasn't the shower but the one for under the sink in the kitchen as we have only a tank heater with one gallon there!
The price was about 8-15 Euros!
