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.
