    I own a Rheem gas hot water heater; temperature control dial is set to the lowest setting; water temperature still rises to a dangerous 150 degrees farenheit; Can the temperature control valve be recalibrated or replaced.

    Yes it can and probably should be. Of course all of the electronics should be tested before just sticking new parts on and hoping for the cure. A plumber would be able to test everything and then make whatever repairs are necessary.

    Depending on the age, it might be under warranty. I'd give them a call. I'd also review the troubleshooting guide in the manual. If you don't have that, you can probably find it on their website.

    For adults this is a 3rd degree burn in 2 seconds.

    This is also why my city requires all new WH installations/replacements to have a tempering valve on the outlet. Now, those can go bad, too, but it's a secondary safety measure.

    Having the water that hot has some advantages IF you have a tempering valve...it makes it look like you have a bigger tanks, and will kill any bacteria that may be in the water. It costs more to keep it hot, though.

    valve

    IT can be replaced, but should NEVER be recalibrated.

    Thanks everyone for the information provided. Since the unit is 8 years old, I've decided to install a new HWH.
