What is the Best Setting for Longevity of the Water Heater?

The best temperature at which to set your water heater is between 120 - 130 degrees. Water heating accounts for 15% of a home’s utility bill. It seems that most homes maintain their hot water heaters at a pre-set temperature of 140 degrees, which is higher than actually needed. By lowering the water heater temperature down to 120 degrees, you can cut the cost of your utility bill. By lowering your water heater temperature every 10 degrees you will be able to save 5% of your energy costs. If you overheat your water, you have the danger of scalding yourself and your family. The US Consumer Product Safety Commission says that overheated water in homes causes about 3,800 injuries and 34 deaths per year. Most adults will suffer third-degree burns if exposed to 150 degree water for 2 seconds or 140 degree water for 6 seconds. Lower water temperatures will also save the water heater – less mineral build-up and corrosion, making it last longer and work at top efficiency. Experiment with the temperature, start out at 120 and see if the water gets hot enough for your needs.
