How To Change The Temperature On Your Electric Water Heater





If you are running out of hot water when taking a shower, you may want to turn the temperature on your electric water heater up. Increasing the temperature on your water heater will increase your electric bill but only in the slightest. For each 10° degrees you go up (meaning hotter), your electricity usage may go up 3% to 5% percent. For each 10° degrees you go down (meaning cooler), your electricity usage may go down 3% to 5% percent. So consider the cost benefits when increasing or decreasing your water heater temperature.

Step 2:
Remove thermostat/element covers.
(usually 2 covers – one on the top for the top element and one on the bottom for the bottom element.)
After removing the covers, save the screws in a safe place.
Pull out insulation to access the thermostat control.
Don’t touch or move wires.

Step 3:
Use a flat tip screwdriver to adjust the top and bottom thermostats to about 120° degrees.
The temperature of 120° degrees is good for most homes however if you are running out of hot water frequently, adjust the temp higher.
For homes that use more hot water, set only the top thermostat 5° to 10° degrees higher.

Turn power back on to the water heater and enjoy your new water temperature settings.

I found the easiest solution to this problem was to go with a tankless hot water heater.
My old traditional hot water heater finally bit the dust and, reluctantly, my husband talked me into a tankless unit.
After reading a ton of reviews I finally found a great one.
This was spot on and the temperature control is sooo simple.
I even talked my hubby into buying a remote for the unit.
Now I know exactly what my temperature is on my water.
The tankless unit is wonderful.

The water running out of my faucet doesn’t feel hot, even when I turn up the hot water tab all the way. Knowing how to change the temperature of the water coming out of my water heater will help me fix the problem. The first step seems like it would help to prevent any injuries. I always forget that the circuit breaker is connected to my water heater, so I should remember to turn off both the circuit breaker and the power to my house before adjusting my water heater temperature.
