Water Heater - Electric
Homeowner Care and Maintenance
Carefully read the manufacturer's literature and warranty for your specific model of water heater.
Drain Tank
Review and follow the manufacturer's timetable and instructions for draining several gallons of water from the bottom of the water heater. This reduces build-up of chemical deposits from the water, thereby prolonging the life of the tank as well as saving energy dollars. Also drain the tank if it is being shut down during periods of freezing temperatures. Carefully follow the instructions in the manufacturer's literature.
Element Cleaning or Replacement
The heating elements in the water heater will require periodic cleaning. The frequency is determined in part by the quality of the water in your area. Again, refer to the manufacturer’s literature for step-by-step instructions and drawings, or contact an authorized service company.
Pressure Relief Valve
At least once each year, manually operate the pressure relief valve. Stay clear of the discharge line to avoid injury. See manufacturer's literature for diagrams and detailed instructions.
Safety
Keep the area around a water heater clear of stored household items. Never use the top of the water heater as a storage shelf.
Temperature
Temperature settings on an electric water heater will produce approximately the temperatures listed below:
Hot 120 degrees F
A 130 degrees F
B 140 degrees F
C 150 degrees F
Very Hot 160 degrees FThe recommended setting for operation of a dishwasher is B, or 140 degrees. Higher settings can waste energy dollars and increase the danger of injury from scalding. Hot water will take longer to arrive at sinks, tubs, and showers that are farther from the water heater.
