thermostat preference[edit]

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.

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)[reply]

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)[reply]

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)[reply]

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!
