Hot Water Tank Temp's

I am trying to determine what the temp settings are on my HWT dial. See image included. What is each bar adjustment 5 or 10 degrees etc. Thanks for any feedback.

Model of Tank: John Wood GSW Superflue

Is the thick red vertical mark right after the work temp 120 Degrees

Yes the red mark should be 120 deg. One way to find out is try it. 120 is all your need in a home.

Set it this am up to the thick bar, just curious what the bars were. Thankyou for taking the time to post back.

Just a guess, 120 divided by 6 = 20.

Well i picked up a kitchen cooking thermostat and let the water run for a couple of minutes in a sink closest to the hot water tank and it got up to 138 degrees (ouch). Turned it down and will check the new setting tomorrow.

Lots of things can effect the temp. The way your checking it will be fine.

Do you have kids in the house? If so...set it down a notch or so.....

Remember, most dishwashers use the heater to heat of the water if it's not hot enough...but you don't want to get the kiddo's too hot....

Yes, that's the only adjustment you need to make, the dishwasher will have a setting for a high temp wash. My hot water was scorching when I bought my house. When I replaced my water heater I set it at 120 deg. I had to learn to adjust the faucets when I used a lower hot water heater setting but no there is no scalding water from the faucets unexpectedly. And there actually is a difference in my electric bill.:thumbsup:
