A water heater can be the second largest energy user in your home, after your
heating and cooling system. That’s why it’s important to make a wise choice
when you are replacing an existing water heater or purchasing a new home with
a choice of equipment.
To determine the actual costs of using a water heater, you should compare
the purchase prices of the models you are considering and their lifetime operat-
ing costs. In most parts of the country, a natural gas water heater can operate for
about half the cost of an electric water heater, although the natural gas unit may
cost a little more to buy. Natural gas water heaters come in a wide range of sizes
and features so you can easily select one that meets your family’s needs.
This publication will help you find the natural gas water heater that is right
for your home and your budget.
