As the autumn chill sets in (and winter’s just a skip away) people tend to use more hot water. Because you’re cold, you may take an extra long shower. You may use hand washing as a way to warm up a little.
First of all, pay attention to your water habits in the cold months. Secondly, you can save energy and cut costs by simply adjusting the temperature setting of your hot water heater. According to the U.S. Department of Energy, for each 10ºF reduction in water temperature, you’ll save between 3%–5% in energy costs. Many water heater thermostats come set at 140ºF, but most families are fine with them set at 120ºF.
Other benefits include less chance of a scalding burn and reducing your water temperature helps to slow mineral buildup and corrosion in your water heater and pipes. This means your water heater will work longer, better. Check out your water heater owner’s manual for instructions about how to turn down the thermostat.
