Most people don’t think about their water heater until it suddenly dies. Then the priority becomes replacing it as quickly as possible. In the long term, this can be an expensive proposition. Water heaters vary greatly in efficiency, so know in advance which one is right for your home.
How this helps
Water heaters come in a wide variety of sizes and types. When you buy in a rush, you risk getting the wrong one for your house, which can result in a ton of wasted energy over the years. Know in advance which one you want (and if your heater is old enough, consider replacing it before it breaks).
* The U.S. Department of Energy offers great advice on choosing a water heater.
* Wrap your water heater with an insulation blanket.
* Set your water heater no higher than 120° F.
