One of the most common myths about water heaters is that they should be set at 120 degrees or less. While changing the temperature of your water heater may save you money, it could put your family’s health at risk. You may also prolong its life and put your family at risk by setting it higher. Read on to learn more about the pros and cons of changing water heater temperature.
Setting a water heater’s temperature to 120 degrees can save you money.
It’s not hard to see how setting a water heater’s temperature to 120 degrees can save you money. Most water heaters operate at a lower temperature. It will save you money and prevent you from paying for high-temperature water, but it might not be the best idea for your home. But if you are concerned about scalding and the development of pathogens, you should consider setting your water heater’s temperature to 120 degrees.
Using a thermometer to check your hot water temperature is a simple way to save money. You can do this on both electric and gas water heaters. The thermostat dial is typically located on the gas valve, and the electric water heaters have two panels containing thermostat dials. To reach 120 degrees, you must remove the cover panel. For water heaters that have two panels, you must make two adjustments.
The water heater’s temperature can also put your family’s health at risk.
While some water temperatures are acceptable, others can threaten your health. For example, changing the temperature of your water heater when it is cold can increase the risk of Legionnaires’ disease. Bacteria in stagnant water cause Legionnaires’ disease, and the World Health Organization recommends a water heater temperature of 140 degrees or higher to keep the bacteria at bay. If you’re worried that the temperature is too high or too low, you may want to install an anti-scald device.
If you have young children, raising the water heater’s temperature may be a smart way to save energy while ensuring that everyone gets a hot shower. It will also provide plenty of hot water for other uses. Although you can get away with a low-temperature setting if you live alone, you may want to raise it for a family with young children or infants. Hot water can harm children with sensitive skin. Water heated to 140 degrees Fahrenheit can cause third-degree burns in just five seconds. A water heater temperature of 120 to 130 degrees Fahrenheit is ideal for children under three.
The water heater’s temperature increases the unit’s lifespan.
Changes in water heater temperature will increase the lifespan of your unit by allowing the bottom element to run longer. This will send hot water up the tank, extending the time until the top of the heater cools down. Unfortunately, it may also result in additional gallons of hot water. These are only a few reasons why a water heater should be appropriately maintained. The Occupational Safety & Health Administration recommends maintaining water heaters at 60 degrees Celsius and 140 degrees Fahrenheit. Although the risk of Legionnaire’s disease is relatively small, it is still a concern. A high-end estimate suggests that there are about 18,000 cases of the disease each year in the United States. Nevertheless, there are other benefits to lowering the temperature, such as reducing energy bills and extending the lifespan of water heaters.
The water heater’s temperature is the most vital safety feature.
Your water temperature is one of your water heater’s most critical safety features. If it changes without reason, it’s time to replace it. Unfinished areas of the home are harder to keep hot, and water heaters wear out faster because they have to work harder. To extend the life of your water heater, make sure you have the temperature checked by a licensed plumber regularly.
