Talk:Thermostatic mixing valve

thermostat preference
the following is internally inconsistent;

Quote: "The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static mixing valve, provides increased safety against scalding, and increased user comfort, because the hot-water temperature remains constant."

The use of a thermostat (which controls the tank water temperature) for increased safety would require storage of the water at a lower temperature that is safe for legionelia. I question whether the water temperature fails to remain constant with a mixing valve. That is its job to keep the temperature lower by mixing. Constant inputs mean constant outputs whether controlled by the mixing valve or the shower valve.

How does it work, though?
The articlere-states what it is - a mixing valve, what it's for - to mix hot with cold fluid: but it says nothing about how it does it. It's not clear to me -- is there electricity involved or not? Is it the mechanical design? The properties of the materials used? If I already knew, I wouldn't be looking it up. — Preceding unsigned comment added by 109.151.212.24 (talk) 13:20, 22 August 2014 (UTC)

What does it really do, though?
I came here with the single question - does a mixing valve mix only, or does it also have a regulatory element to maintain a constant temperature of the outflow water? This article does not answer that basic question. Tedtoal (talk) 15:00, 10 October 2016 (UTC)
 * A "mixing valve" need not. A thermostatic mixing valve does. It contains a self-contained element, typically a wax motor, as the article states.
 * It could use some copyediting though. Andy Dingley (talk) 16:07, 10 October 2016 (UTC)

Everything you ever wanted to know about it
It's really quite a neat little invention, and it does serve some important purposes. If anyone wants to expand on this article, check out the paper below. It looks pretty detailed!
