During cold or winter season, there is really no need to scald yourself with hot water from the shower. In fact, you can simply turn your water heater to 120 degrees. You will not only save your skin from scalding, you are also doing a big favor in your pocket.
You can save from the electric bill up to about 10% compare if you heat up your water to 140 degrees. Your water heater will also serve you much longer as well as the pipes in your water plumbing because there will be a decrease in mineral build up and corrosion.
You are also helping the environment because you will help eliminate around 200 pounds of emissions each year. It will be a great help for Mother Earth too!
