How to Insulate Your Water Heater

Are you looking for quick, inexpensive ways to save money on your home energy bills? One of the easiest ways you can save money (besides keeping the lights off for the next month) is by insulating your water heater. Save energy; keep money in your wallet.

Water Heater

Check the Tank

If you’re unsure whether or not your water heater's tank is currently insulated depends on its age and R-value. Newer tanks are almost always insulated, but any that are more than just a few years old with an R-value that’s less than 24 - insulate the tank. Doing so will save you up to 15 percent in water heating costs. Most insulation blankets can be purchased for roughly $20 and will easily save you more after the first few months.

Step-By-Step Guide

  1. Before you do anything, make sure the water heater has been turned off. For electric models, turn off that specific circuit on the main panel. For gas models, shut off the gas line leading into the fixture.
  2. Next, cut the blanket to fit the size of your water heater. However, make sure you leave the top portion open so it doesn’t cover the top of the unit (especially on gas models).
  3. Temporarily tape the newly cut blanket onto the tank so it stays in place. Cut out spaces for all of the panels, valves, pipes, and leave a space between the bottom of the blanket and the burner.
  4. Once all of the spaces have been cut out, tape the blanket in place on the tank. Make sure all of the valves and panels have enough room to breathe and then you can turn the water heater back on.
