If you really want to lower your energy costs, you need to lower the temperature on your water heater. Your water heater is actually one of the biggest users of electrical energy in your home. One of the best ways to lower your water heater costs is by turning down your water heater; when the temperature is lowered, your water heater will not have to work as hard to hit its target temperature every time you need hot water, thus lowering your overall water heater costs.
Test Your Water Temperature
The first thing you need to do is test what temperature water your hot water heater is actually producing. To do this, you are going to want to turn one of your hot water faucets all the way on, and let the water run for a minute to ensure that you are getting the hottest water possible out of your faucet.
Then, fill up a container that is at room temperature, such as a pot or pan, with the hot water. Next, take a thermometer and find out what temperature the water is. Write down what temperature your hot water is right now. If your hot water is over 120 degrees Fahrenheit, you have room to lower your water heater temperature settings.
Lowering The Water Temperature
Second, you are going to want to lower the temperature on your hot water heater. On some hot water heaters, you can actually see what temperature your hot water heater is set to and lower it to the target temperature of 120 degrees Fahrenheit. Then, run the faucet, collect water and make sure that the temperature setting is actually correct.
However, on most water heaters, the water temperature dial is labeled with the terms hot, warm, and cold, with little indentations between each description. If you have a vaguely labeled water heater, it is going to take a little more effort to get the settings just right.
You are going to want to lower your water heater one notch or setting on the dial. Then, you are going to want to run the water out of one of your hot water faucets for a few minutes, then fill up a container again and take the temperature of the water. If the temperature is around 120 degrees Fahrenheit, you don't need to do anything else. If the temperature is above 120 degrees Fahrenheit, turn it down another notch and test the water again. Repeat this process until you hit the target temperature.
If you really want to lower your water heating costs, you need to figure out how hot your water is now, and then lower the temperature on your water heater to 120 degrees Fahrenheit, which is the lowest safe temperature you can set your water heater to.
