Special Considerations

Plan Ahead (For Replacement)
Don't wait until your existing water heater fails before you look into replacement. It often makes good economic sense to replace an old inefficient model with a high-efficiency one even before the old one fails. With storage water heaters, read the Energy Guide labels and buy an efficient model.

Life-Cycle Costs for Water Heaters
When you're choosing a water heater, don't be tempted to simply buy the lowest-cost model available. Water heating uses too much energy to make the decision lightly. The unit's initial cost is a small fraction of the money that will be spent operating it over its lifetime.
