Several sights have these. Here is one with PEX fittings.

Looks similar to the one that came on my new Isotherm water heater.

I think the ABYC standards may have recently been updated to require thermostatic mixing valves. I should have installed one the first time I realized how hot engine heated hot water could be.

So, These valves all reside in the potable side, not on the engine water side. Seems to be different information than what was presented in some posts. I guess it really does't need throttling of the engine coolant in the HWT as much as the potable tempering.

If it make the hot water last longer, the inventor should get a Nobel.

There are two type of valves with the same concept but different operation.

A 'Tempering valve ' will attempt to modulate the water to a preset temperature.

Should it get hot water , but NO cold it will pass the hot.

An anti "Scald valve" will shut off the hot if it can not maintain the temperature.

Difference in price as well as operation. CAVIAT EMPTOR!

AS to weather the HW heater that is installed has an engine coolant slowing feature , google the mfg literature, there are many different units.
