When a water heater comes straight from the manufacturer, the setting on the thermostat is typically right around 140°F. This has been typical of the industry for many years. And yet, it’s not necessarily the best way of doing things.
Many people keep their water heaters set to the original manufacturer settings throughout the lifespan of their units. But lowering the temperature could actually save you money, as it helps the system to work more efficiently.
So Why Is 140° Still the Norm for Manufacturers’ Settings?
There are a couple of explanations for why your water heater may have come preset to an extremely hot temperature of 140°F. You don’t need your water heater to be this hot to be comfortable, and it uses a lot of energy at this temperature setting. But this isn’t necessarily the concern of your manufacturer. After all, it’s easier to prove a water heater’s effectiveness if, soon after you turn it on, the water coming out of the faucet is very hot, which may help to boost sales.
In addition, some people believe that warmer temperatures help to fight off legionella, a form of bacteria responsible for Legionnaire’s disease. However, legionella is sterilized at about 113°. A higher temperature may still serve as a safeguard.
Bring the Temperature Down to 120° for Safety and Efficiency
Lowering the temperature on your water heater will help your system to run more efficiently and will provide the right amount of heat for your showers. It also helps to prevent scalding, although anti-scald devices are also available for your shower.
For more information, talk to a local contractor. They can help you to make the right decision for your home and family, and provide a maintenance visit that may help the unit to run more efficiently regardless of temperature setting.
