1. Examine the Water Heater
The first step is to examine whether your water heater needs any type of adjustment or not. Whenever you install a new water heater, they are mostly set to 120 °F temperature which is normal and should not exceed for safety reasons.
Moreover, in order to protect yourself and your family members from different unpleasant accidents, better leave it alone.
If you witness cold water then the issue might be due to any damaged water heater elements or the problem might be due to poor insulation. In such a case, a plumber can guide you to the actual cause because you are not a pro at it.
Turn the Knob of the Water Heater
There are two different types of water heaters including a gas water heater and an electric water heater. If you are using a gas water heater it will be easy for you to set the temperature just by turning the knob that is located at the bottom.
If you turn up the water heater knob counterclockwise, it will heat up the water and if you will do it clockwise, the water will cool down. Normally the lowest temperature of a gas water heater is 90–110 °F and the highest temperature is 140–150 °F.
The knob or a dial doesn’t contain any numbering so it will be difficult for you to set it at the required temperature. For this purpose, you can examine the temperature a few times after changing the settings as it will give you a clear idea.
Increase the Temperature
There is nothing more soothing than being able to enjoy warm water at a cold temperature. Not only for bathing but you also need warm water for cleaning purposes. Your dirty appliances that need a good wash can be thoroughly cleaned with warm water.
Hot water can better deal with bacteria and let you get rid of them as compared to cold water. Hence, never enhance the temperature above 120 degrees because it can be dangerous, especially for your kids.
Decrease the Temperature
Have you experienced high heating bills but don’t know the exact reason? It is mainly due to the high temperature of your water heater that resulted in high bills. It is always great to set them at the normal range especially if no one is using water.
2. Adjust the Temperature
Now you have fully examined the water heater, if there is any adjustment needed, follow the below steps.
Turn off the Power
Before jumping into any electrical work, the first task is to turn off the main supply to avoid unpleasant accidents. Once you have tuned it off, double-check because you can not take any risk.

With the help of a flat-blade screwdriver, loosen the two screws that will be located at the bottom and top of the panel in order to access it. Once you are successful at it, carefully place the panel and do not misplace the screws otherwise you will be in a trouble.
Eliminate the Insulation
In order to reach the water heater thermostat controls, you have to remove the insulation that is placed inside the water heater to cover the thermostat. This insulation comprises styrofoam material.
Change the Settings
You will clearly see the settings of the water heater once you reach the thermostat control. If you want to decrease the temperature, you can turn the screw counterclockwise but if you want to increase the temperature, you can turn it clockwise.
Once you are done, put everything back at the right pace including the panel and screws, and double-check whether everything is tightly fixed or not. Once done, turn on the heater.

Before adding hot water to a glass, ensure you have already prepared the cooking thermometer because the water might cool down if you let it wait for even some seconds.
Once you have checked the temperature, do not forget to note it down in order to get the perfect temperature setting. If the temperature is 120 °F, you do not need to change the settings but if it is above or below this rating, repeat the above-mentioned process.
Retest the Temperature
After making the changes, you have to retest the temperature after at least 3 hours. While doing this work, be concerned about all the safety precautions in order to fully protect yourself.
The Correct Temperature Range
There are numerous reasons that depict why you should pay special consideration to adjusting the water heater temperature.
