How To Insulate Your Hot Water Tank

Water tanks are storage containers usually used for storing water. Aquariums, storage tanks, and portable water tanks are some of the kinds of water tanks often used. A water tank provides storage for drinking water, irrigation, fire suppression, farming and livestock, chemical manufacturing, and food preparation as well as many other possible solutions. Portable water tank is a collapsible temporary tank used for the reserve storage of water in firefighting, emergency relief, and military applications

Water tanks are made up of various materials like polyethylene plastics , polypropylene plastics, fiberglass, concrete, stone, and steel. Most of the hot water tanks are found in basements, service rooms or garage, continuously maintaining 40 or more gallons of hot water that is always ready for use. But maintaining hot water consumes plenty of energy and becomes costly.

To save on utility bills you can reduce the temperature of the water heater. Maintaining water with a temperature of above 120 degrees is a waste of energy and there is danger that someone could by chance get burned.

Insulating your water heater is another step you can take to conserve energy and minimize cost of electricity. You can use a water heater insulating kit that consists of an insulating fiberglass blanket with strong plastic sheeting and strips of heat-resistant tape to secure in place the fiberglass blanket around your hot water tank. Some hot water tanks insulating kits include pipe insulation used to insulate hot-water pipelines.

Here’s how you can insulate your hot water tank:

  1. Clear up the space surrounding your hot water tank to facilitate movement.
  2. Remove any straps or braces attached to your water tank before you start doing your insulation and make sure that you put the straps or braces back to the water tank when you've finished insulating to secure the tank in place.
  3. Make sure that the outer part of the water tank is clean. Wash the top of the water tank well otherwise the tape won't stick on.
  4. Determine the measurements of your hot water tank.
  5. Using your service knife and based on the measurements you have, cut the insulation blanket. Put a few inch extra allowance on the insulation blanket to enable you to cover the water tank fully.
  6. Try if the blanket fits and determine where the insulating blanket should overlap.
  7. Cut the insulating fiberglass from top to bottom where the insulating blankets will overlap.
  8. Cover the water heater with the insulating blanket and secure it with tape.
  9. With your scissors cut openings to allow easy control of the pressure relief on drain valves.
  10. The insulating blanket should be secured to the top of the tank and seal the overlap ridge from top to bottom.
  11. With water pipe insulation made of foam, wrap the first 10 or so feet of the hot water pipeline streaming out of your tank.
  12. Reattach any bracing or strapping.

By reducing the amount of heat that is lost through the wall of your water heater, you will save a lot of energy and money.
