Heating water is the second biggest energy cost in a typical household. Choosing the right water heater can make a big difference. Natural gas water heaters are not only the faster way to heat water, they’re also significantly more efficient and economical than electric models.   
 
For example, a 40-gallon natural gas model heats as much water as a 50-gallon electric model—and does it faster and more efficiently. It’s like getting two bathtubs full of water heated with natural gas for the same cost as only one tub heated with electricity.

Upgrading to a modern natural gas boiler gives you the benefit of the proper air-to-fuel mixture without the need for constant adjustment, helping you maximize efficiency.

Homes that are well-insulated, air-sealed and have smaller spaces to heat are ideal for an integrated space- and water-heating system.

Using a single appliance for both space and water heating can give you an efficiency rating of more than 90 percent for both uses.
