Using the "Patented" Reflective Foil Hot Water Heater Jacket stops 97% of Radiant Heat loss! Heating the Water in your Hot Water Tank at home is the second largest energy consumption next to Heating and Cooling Air. Your Hot Water Tank continues to work even when you are at work, sleep or on holidays. As the water cools down due to the loss of heat, your Hot Water tank starts up again to maintain a desired temperature. The cost savings using a Hot Water Heater "Reflective-Foil Jacket" are immediate and also helps prolong the life of your Hot Water Tank. The Patented "Reflective Foil" is 3/16" thick which has a single layer of polyethylene bubbles sandwiched between two highly reflective surfaces. It is specifically designed to reduce the amount of radiant heat transfer.
