Did you know that the temperature setting you choose for your water heater impacts its longevity, efficiency and other factors? If you are like most Lakeland residents, you probably wonder what temperature to choose. The U.S. Department of Energy recommends 120 degrees Fahrenheit in most cases. This is usually ideal for energy efficiency, comfort and safety. This guide will explain why this is an ideal temperature and address concerns about using other temperatures.
Understanding the Dangers of a Default Water Heater Temperature
Water heaters usually have a factory setting of 140 degrees Fahrenheit. However, this does not mean it is ideal. If you use 140-degree water without adding cool water, it is more likely to scald your skin. This is important to consider if you have elderly people or small children in your home. Reducing the temperature to 120 degrees can also help you save as much as 10% on your heating costs. Studies show that 120 degrees is a suitable temperature for preventing most harmful bacteria growth as well. However, water heaters should be maintained well at this temperature to minimize risks.
The American Burn Association says that turning your water heater down from 140 to 120 degrees can reduce the risk of burns. It only takes a few seconds for 140-degree water to burn your skin. For 120-degree water to burn you, it would take about five minutes of continuous exposure.
Importance of an Efficient Water Heater
A considerable portion of your home’s energy use goes to heating water. As a result, turning down the temperature can reduce usage. The Department of Energy says that lowering the temperature from 140 to 120 degrees can help you save up to $60 every year on energy costs. Many people do not realize that water heaters run frequently. They must use energy to keep the water in the tank at a certain temperature until it is used. If you turn down the temperature, your water heater does not need to run as much. A lower temperature can reduce mineral buildup in the tank, which helps your water heater last longer. There is also less strain when your water heater goes through fewer heating cycles. That reduction can decrease repair needs as well.
Why Lower Temperatures Are Risky
Some homeowners consider turning their water temperature lower than 120 degrees. However, this is not ideal. One concern that exists with water heaters is the growth of Legionella bacteria, which can cause Legionnaires’ disease. For this substance to grow, the maximum temperature is 108 degrees Fahrenheit. Maintaining your water heater and monitoring the temperature reduces the risks of Legionella bacteria. If you are concerned about this, you may consider installing a hot water recirculation system. It keeps water moving to reduce bacteria risks.
Factors That May Affect Water Heater Temperature Settings
Some factors may affect your personal choice of temperature. In some cases, a higher temperature may be better. These are some examples of such situations.
Occupants With Compromised Immunity
Some older people or those who have certain health issues may have weakened immune systems. If this is the case, it is better to set the temperature between 130 degrees and the factory setting. Doing this can further decrease bacteria risks. However, it is also important to use anti-scald components on all showers and faucets.
Heatless Dishwashers
If you have a dishwasher, check to see if it has a heating element. Although most modern dishwashers have one, older ones may not. A temperature closer to the factory setting is better if you use a dishwasher frequently and do not have a heating option. Be sure to read your owner’s manual for your dishwasher before you select a temperature setting for your water heater.
How To Change the Temperature on Your Water Heater
Changing the temperature is a simple process that most people feel comfortable doing on their own. However, if you are uncomfortable, call a professional. You may also find instructions in your owner’s manual. The instructions vary for electric and gas water heaters.
Electric Water Heater
If you have an electric water heater, start by turning off your power. Do this on your electrical panel. Your water heater may have separate thermostats for the upper and lower elements. Adjust both thermostats with a screwdriver, and they should be the same temperature to ensure consistency. Turn on the power. Let the water warm up for a few hours, and test the temperature from a water source in the house. Make adjustments if needed.
Gas Water Heater
For a gas water heater, turn the control knob to the pilot setting. Look for the thermostat, which is usually near the bottom of the tank. Turn it to your desired temperature. After a few minutes, ensure the system is stable before you turn the control knob back on. Wait a few hours for the water to reach the right temperature. Next, test the temperature of the water from a faucet. If it is incorrect, make additional adjustments using the right steps. Always be careful with gas appliances. Follow the correct safety steps if a pilot light goes out.
