Flushing an electric water heater does not require a license or any special training, and it can be completed in less than an hour. Easy-to-follow instructions are available online at HomeTips.com.
Mineral deposits gradually accumulate in water heaters, settling to the bottom of the tank and solidifying into a concentrated layer of residue. This residue eventually interferes with the heat transfer from the heating element to the water in the tank. Over time these deposits cause corrosion.
Electric water heaters need to be flushed regularly so they can operate efficiently and provide a satisfactory supply of hot water. Homeowners can save both time and money by doing this project every two years.
