Do-It-Yourself Project: Insulating Your Water Heater
Your attic isn't the only thing that needs insulation. Wrapping the tank and hot water pipes on an older water heater can significantly reduce the amount of "standby" heat loss, saving you money on your energy costs.
A tank wrap is a thick fiberglass blanket, secured around the tank by waterproof tape. You can find water heater insulation kits at your hardware store or home center for about $20. This cost can be paid back in energy savings in just a few months.
Newer water heaters (less than seven years old) don't need a tank wrap, but can benefit from pipe insulation, which can be purchased separately. Pipe insulation comes as either a foam tube slit lengthwise, or as a small roll of fiberglass wrap.
Step 1
If your water heater is electric, shut off the power at the circuit panel or fuse box.
Step 2
Clean off the top of the water heater - it needs to be free of dust and debris for the tape to stick.
Step 3
Measure the position of the thermostat at the bottom of the tank, and mark the appropriate position on the tank wrap with a permanent marker.
Step 4
Use strong scissors to cut out the area for the thermostat.
Step 5
With a helper, hold the wrap around the tank and secure with the vinyl tape included in your kit.
Step 6
Double-check the position of the cut-out around the thermostat and burner access, making sure there's plenty of clearance.
Step 7
Install the pipe insulation on both the cold and hot water pipes connecting to your water heater, and on any hot water pipes accessible throughout the house.
