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