Are you happy with the temperature of your hot water? Adjusting it might be simpler than you think! Hotter water has its advantages and disadvantages, the same holds true for cooler water temps. If you’re uncertain, do some research to learn what’s best for you and yours.
IMPORTANT – Read and follow the printed Installation Instructions that came with your water heater. The printed Instructions and product labels contain model-specific information, important warnings and safety notices. If you lack the necessary skills to install, troubleshoot or repair the water heater, get help from a qualified person.
Gas Water Heater Adjustment:
If you have a gas water heater you are in luck as far as adjusting the temperature! There’s nothing to remove or replace. Simply turn the dial located on the front of the gas control valve.
The warm setting will be in the 90 to 110 degree range. The hot setting will average 140 to 150 degrees.
Electric Water Heater Adjustment:
Turn off the water heater breaker. If you have a double-element water heater, remove both access panels (upper & lower).
For single element water heaters, remove the lower panel.
Pull the insulation to the side or remove it so you can see the thermostat.
Remove the plastic cover if it doesn’t have an access hole for the adjustment screw.
The thermostat adjusting screw is located at the bottom of the thermostat, just above the element. As you can see you’ll need a small flat blade screwdriver.
***Remember: if you have a dual element electric water heater (the vast majority) make sure both thermostats (top & bottom) are adjusted to the same temperature.***
Replace the plastic cover. Place the insulation back over the thermostat and element. Replace the access panels and turn the power back on.
