Set your water heater temperature no higher than 12 degrees for maximum efficiency. A higher value can reduce efficiency and increase the chance of sunburn.
Wrap your water heater in an insulating blanket to help improve performance and reduce heat loss in standby mode.
Be sure to keep 2 feet of space around the unit.
Use the "vacation" setting on your water heater when you're out of town, which keeps the pilot light on without heating the water.
This helps prevent unnecessary wear and tear on the water heater caused by mineral deposits.
Replace the pressure and temperature(PT) valve on your hot water heater every three years to protect it from extreme pressure and temperature.
Don't forget to schedule your water heater's annual tune-up. Your plumber should check the pressure relief valve, drain the tank to remove any sediment if necessary, inspect the tank and connections for rust, wear or corrosion, and replace the worm gear anode rods.
If any of these Tips occur, contact a professional water heater technician. Trying to manage repairs yourself can incur unnecessary costs if something goes wrong.
