Insulate your water heater tank

Why? If you have an older water heater, additional insulation can cut standby heat losses by 25-45% and reduce water heating costs by 4-9%, saving energy and money. Specially designed water heater "jackets" can pay for themselves in a year or less.
How it works: A typical water heater creates and keeps hot water in a storage tank. When the tank loses heat over time, additional energy is expended to keep the water hot. A specially designed water heater jacket helps keep the water warm and reduces energy costs.

Step by step:
  1. Determine the size you need. Measure the girth of the water heater or consult the label to see how many gallons it holds.
  2. Buy the cover. Find the jacket at your local home improvement store.
  3. Check for more information. Check your water heater owner's manual, warranty, and any instructions included with the jacket before adding it.
  4. Install the cover according to instructions.

Good to know: Insulating a gas-fired water heater can be difficult and improper installation could cause safety hazards. The easiest and safest solution is to have a qualified professional install the insulation.
