water heater tempering valve

[KULTULZ]

Does a water heater tempering valve negate the need for point of use thermostatic mixing valves?

Yes No Maybe . lol
Is this a private residents ?
Public buildings require tempering valves in the restrooms.

If you talking about a shower valve code, requires it to be a balance pressure valve.

Not enough info given again...

Yes, a residence. So I will still need mixing valve(s) @ point of use (shower heads) in addition to a tempering valve (personal choice to use) @ the water heater?

It makes sense.
