The temperature at which your hot water heater is set plays a key role in your overall comfort and safety. The ideal setting for your water heater should be around 120 degrees Fahrenheit (49 degrees Celsius).
Health and Safety:
Keeping the temp at 120 degrees helps prevent bacterial growth and minimizes scalding risks.This temperature is considered safe for daily activities such as showering, washing dishes, and doing laundry. This is also hot enough to kill harmful bacteria such as Legionella which thrives in cooler temps.
Too Low or Too high:
Setting the temperature too low can not only leave you shivering, it will take longer for the heater to heat to the desired temperature. Setting the temperature too high can lead to mineral buildup in the tank, causing damage over time.
Energy Savings:
Higher temperatures require more energy to maintain, so by setting your water heater at a lower temperature, you can reduce energy consumption and heat loss through the pipes. The ideal temperature of 120 degrees Fahrenheit can help you save energy and reduce your monthly bills. It is also a good idea to insulate your hot water pipes to further improve energy efficiency and reduce heat loss.
Appliance Considerations:
Some appliances like dishwashers may need a higher setting temporarily for optimal performance. In such cases, it is recommended to adjust the temperature setting accordingly and then lower it back to 120 degrees Fahrenheit once the appliance has finished its cycle.
Preventative maintenance is key to keeping your hot water heater running smoothly. Inspect your hot water heater periodically for any leaks or signs of damage and check that the dial is still at the proper setting.
