Save 4-9% water heating costs by
insulating your hot water heater to prevent standby losses.2
Water heating can account for
14%–25% of the energy consumed in your home. You can reduce your monthly water
heating bills by selecting the appropriate water heater for your home or pool
and by using some energy-efficient water heating strategies.1
Unless your water heater's storage tank already has a high R-value of insulation
(at least R-24), adding insulation to it can reduce standby heat losses by
25%–45%.2 This can save you up to 9% in water heating costs. Adding additional insulation to your water heater can
substantially reduce your energy costs.
Install a radiant barrier insulation blanket which is considered a green building product.
The radiant barrier blankets are
manufactured of at least 40% recyclable materials. A radiant barrier
foil-foam-foil blanket eliminates standby losses by keeping heat from escaping
which keeps the water hotter longer and prevents unnecessary start and stop
operation or the water heater. Flexible foam and aluminum
materials are used by consumers routinely and are safe for the environment.
Insulating your storage water heater tank is fairly simple and inexpensive. Choose one with an insulating value of
at least R-8.

Shield Radiant Hot Water Heater Blanket has a larger piece of material to fit water heaters
up to 26 inches in diameter and 60 inches in height. Kit includes
a top panel for electric heaters to enhance energy savings.
Installer may attach one side of the foil tape to the tank blanket
vertically after cutting to size. During installation, the blanket is
wrapped around the heater and joined together where the other side of
adhesive liner can be removed to join the blanket ends together. The
kit includes 96 inches of scrim-reinforced (has fiberglass strands
embedded in tape for strength) tape with acrylic adhesive that includes
a split back liner to aid in ease of installation. Acrylic adhesive
strengthens with age and resists degradation in temperature extremes.
blanket fits tanks 23.75 inches in diameter or less. Kit does not
include a top panel for an electric tank. Tape for kit includes 100 inches of
foil tape with rubber based adhesive.
tapes with rubber-based adhesive have quick adhesion properties but can
lose its adhesive abilities with age and do not adhere well in higher
than ambient temperatures indoors. Separation between the foil tape and
