Hot water temperature
Everything is working fine but I'm curious why my hot water changes temperature. Sometimes it's too hot to use full on and other times it's about medium hot full on.
Is this perhaps an indication that it's getting old and can't hold a steady temperature, or is it normal to vary? |
It sounds like the thermostat located on the heating element for an electric water heater.
No it is not normal for the temperature to vary. Realistically, though, it is 15 years old. You really should consider replacing it. |
The temperature should be consistent. Most electric water heaters have two heating elements. You can remove the two metal plates on the water heater and adjust the temperature with a screw driver. Both elements should be set on the same temperature. I think the builder sets the temperature at 120 degrees, but I increased mine to 125. Be careful when you remove the metal plates because the edges are sharp. It could be that one of the elements is not working, which may provide an inconsistent temperature.

Also, we notice some difference in temperature with the cold weather, the incoming water is colder...
|
If you are really into this you can test the resistance of the elements to see if they need to be replaced.

Thanks for the advice, everyone.

As to your second point a new 40 gallon heater provides 28 gallons. Not because 28 gallons is forty, rather 28 gallons of cold water displacing 28 gallons of hot makes it so cold that it's not effectively functional as the heating elements cannot over come the temperature loss quickly enough. At 28 gallons the tank is full of 85 degree water which feels cool. |

Although it was "gas" I replaced my last HWH at approx. 16 years (still worked fine) because I wanted something more efficient and TECO gave me a $400.00 rebate to do it. The 40 gal. gas HWH that I purchased cost only a little more than that and had electric flue dampener and electric ignition. I would like to add - I have always flushed my HWH twice a year. I write dates down on the side of the heater with a pencil. :thumbup: |
Ever open you’re 10 to 15 year tank and see the build up?

:ohdear: No.....I have a life! :1rotfl::1rotfl::1rotfl: I put it to the curb and make the call to have it picked up. :rolleyes:
