Water heaters are an important feature in many homes, accounting for about 20 percent of most energy bills. When it comes to setting the temperature, there are several factors you should consider to prevent the need for water heater repair. Here’s a closer look to help you determine the optimal temperature level. 

How to Set the Temperature on a Water Heater

What’s the Optimal Level? 

For traditional and tankless water heaters, the U.S. Department of Energy recommends keeping the temperature at or above 120 degrees. This will reduce the risk of bacteria growth and ensure that the water is hot enough for everyday use. If you prefer warmer water, try raising it in minor increments until you locate the optimal setting. 

What Factors Might Affect Where You Set the Temperature? 

Dishwashers that don’t pre-heat the water may require a higher temperature setting. Bumping it up to 140 degrees will allow for a more thorough cleaning and ensure your dishes come out looking pristine. 

On the other hand, if small kids live in the house, you might want to remain closer to the recommended 120 degrees. It can be tough to teach your young children how to keep faucets at a temperature that won't burn their sensitive skin. 

Are There Risks to Having it Too High or Too Low? 

Water heaters use energy to produce warmth. Setting the temperature too high will naturally cause your utility costs to spike. This could also cause the system to overheat and may require an emergency water heater repair. 

Temperatures that are set too low could also create the ideal environment for bacteria, which can jeopardize the cleanliness of the water supply and encourage the spread of disease.
