Save Money with a Water Heater Wrap

To save on energy costs and ensure a longer hot water supply, consider enclosing the body of your water heater with a tank wrap, a thick fiberglass blanket that's sold at most hardware stores. Secure the ends of the blanket with waterproof tape. Experts recommend wrapping older water heaters; newer heaters that are less than seven years old don't need an entire wrap but can still benefit from pipe insulation.
