Ready to Begin Insulating Your Home’s Water Pipes? You’ll find all the home pipe insulation you’ll need, along with all the tools and fitting covers you’ll need to get the job done right.

Before you begin installing your home pipe insulation:
Check your owner’s manual for the required clearance from the water heater and its flue vent. Certain foams could emit toxic gases if they burn.

Determine the type of insulation to use. For electric water heaters, pipe sleeves made with polyethylene or neoprene foam are the most commonly used. For gas heaters, the safest choice is fiberglass pipe wrap if your pipes are within 8 inches from the flue.

Measure the diameter. Plumbing pipe is measured by its internal diameter (3/4 inch is common), but the actual outside diameter will be larger, depending on the material.

What you need:

  • Tape measure
  • Pipe sleeves or strips of fiberglass pipe wrap from your hardware store
  • Acrylic or duct tape or cable ties to secure the pipe sleeves or aluminum foil tape or wire to secure the fiberglass pipe wrap
  • Gloves, long sleeves and pants if using fiberglass pipe wrap
  • Scissors, box cutter or utility knife

Steps for insulating pipes:

  • Measure. Starting at the water heater, measure all accessible hot water pipes to determine the lengths of insulation needed. Insulating the first 3 feet of pipe from the water heater is especially important.
  • Cut. Using a sharp tool, cut the pipe sleeve or fiberglass pipe wrap to the lengths needed.
  • Fit. Place your cut pieces of insulation along your pipe with the seam face down.
  • Secure. Tape, wire or use cable ties to clamp your lengths of insulation every foot or two.
