Water Heater Sizing, Installation, Maintenance and Operation Tips

Are you looking at buying a new water heater? Make sure it’s the right size first. Then, become familiar with tips for installing, maintaining and operating your water heater for long-term savings.

Water Heater Sizing

Even if your last tank seemed to do its job well, don’t assume it was the ideal capacity. To size a new water heater, add up how much hot water your household consumes during the busiest hour of an average day. This is your peak-hour demand. Find a water heater with a comparable first-hour rating (FHR) printed on the yellow Energy Guide label.

Different fuel sources deliver different FHRs in relation to the tank size. As a general rule of thumb, one- to two-person households need about a 40-gallon electric or gas water heater while a four-person household may need a 50-gallon gas water heater or up to an 80-gallon electric water heater.

Installation

To maximize efficiency, install the following items along with your new investment:

  • Aerating, low-flow showerheads and faucets

  • Water heater and piping insulation

  • Drain-water waste recovery system to preheat cold water entering the water heater

Maintenance

Neglect your water heater and it may last less than a decade. Take good care of it and it could last 20 years or more. Follow these maintenance tips to lengthen the life of your investment:

  • Flush the tank twice a year.

  • Inspect the pressure relief valve and have it replaced if you spot corrosion or rust.

  • Remove and inspect the anode rod and replace it if six inches or more of the core wire is exposed.

  • Inspect the combustion chamber and flue vent on gas- and oil-fired units.

  • Remove and check the heating elements on electric units.

Operation Tips

Save energy and money with these tips:

  • Set the water heater to 120 degrees instead of 140 degrees.

  • Repair leaky faucets promptly.

  • Take shorter showers.

  • Only run the dishwasher and clothes washing machine with full loads.

  • Set the water heater to vacation mode when you leave town.
