Tepid Tap   (+6, -3)  [vote for, against]
This tap is too hot! This tap is too cold! But this tap...

AARGH! Why is it that almost every time you go to use the sink, the two taps are of extreme and opposite temperatures?

I only want to wash my hands! I don't want to get third degree burns or have hands like a cold-blooded lizard. I only want some nice, lukewarm water.

This is why I think every bathroom in the world should be fitted with a third, 'tepid' tap - Not too hot, and not too cold, but just right for everyday use.

while the idea is to have one tap devoted to tepid water, I think the fact that this technology is widely known to exist puts your idea into the "wibni" or "let's all" category [ato_de, May 08 2005]

This is good. There should also be a way to retrofit existing taps so that turning the knobs until you feel the thump of the preset position automatically gives you a tepid temp. (+)

Would it be that those motion detectors used to trigger faucets were preset to prime the faucet according to a preset tepid temperature, say 30C in northern climates to 37C in southern climates, your skin temperature would trigger an adjustment of water temperature within limits of the environment.

Surely this is a mixer tap, and thus widely known to exist? Some continental friends of mine were ranting to me on this subject the other day, demanding to know what this British obsession with limiting ourselves to having 'hot' and 'cold'.

the Brits don't *do* comfort - we're hard and anyway, hot is for washing and cold is for - well, you know!

Baked. Big time. Walk into a bathroom showroom - you'll see.

How about the tap randomizer? Is it going to be hot? Or cold! I know not!

Even better the "OCD Tap" which spews out boiling water for those who need to cleanse their hands of its horrible contamination.

A third tap specifically for tepid water? I doubt that.
-- NickTheGreat, May 09 2005

No, not a third tap but the same tap as all of the other temperatures--an even more amazing idea. An added benefit is that use of the single extended thermal range, or "wide-band," tap reduces the tap landfill waste by fully 66%!

[NickTheGreat], have you actually walked into a bathroom showroom as I suggested? Do so and you will find third, tepid taps gallore.

The third tap has a tempering valve that mixes hot and cold water to give the required temperature. In my country, newly installed hot taps also require a tempering valve to limit the temperature to somewhere around 50°C. I guess the tepid tap is a similar set up, only with a lower target temperature.

I had this same idea. In New Zealand, where I live now, for some silly reason mixing taps are rare in public places. Even lot of new buildings are fitted with two separate taps, Left hand is washed with burning hot water and right one with freezing cold, or was it visa versa? Having a third tap with tepid water would be the answer if they don't want to install mixing taps. Weird people those Kiwis ;)

Having warm water as a mixture of hot and cold is inefficient, and having a warm water tank would be a breeding ground for bacteria. What is needed is a gas-fired warm water on demand tap.

One could easily address this problem by having one hot tap, but allowing it to raise to variable heights. Perhaps the pressure of the water itself could be used to telescope the tap higher as desired. As hot water falls through the air it will cool. It will, of course not get any colder than room temperature. Room temperature water might require a tap high enough to splash a fair bit, and so one might want to make the basin deep - more of a barrel on the ground I think, with the drain at floor level.
