Do You Need a Water Heater Insulation Jacket? Hot water tank insulation saves big money with little effort. Here's a simple test to determine if the answer is YES.
A major source of energy loss at home is an uncovered water heater.
Most water heating systems constantly reheat the water in the tank while waiting for someone to use it. Not a super efficient use of resources.
A quick test to tell if you will benefit from a water heater insulation blanket is to feel the tank with your bare hand. If it's warm to your touch, heat is escaping and insulation will help.
Like putting a cozy on a teapot, covering your hot water tank with an insulating blanket can preserve the heat in your water for more than twice as long as an uncovered tank.
Keeping the water hot means that there is a longer time between heating cycles and for you that means dollars that stay right where they belong... in your pocket.
A properly installed insulating blanket can reduce your water heating cost by 25% to 45% depending on how well insulated your tank was in the first place, how much hot water you use and the ambient temperature in the room where the tank is installed.
Systems that are constantly in use, where hot water is being used as fast as the heater can heat it, will not see results as favorable as a system where the water is heated and then stored in the tank for a period of time in stand-by mode. If the water isn't sitting in the tank long enough to cool down, a water heater insulation blanket isn't going to make a big difference.
