How much does it cost?

The real cost of a tankless water heater

Your up-front costs to purchase and install a tankless water heater will range from about $2,500 to $3,800, depending on the size of your home and the model you choose.  We are committed to giving you the most competitive price as well as helping you select the most appropriate equipment for your family’s lifestyle.


Our customers don’t consider those costs alone — the total cost of ownership is what really matters.  With its energy efficiency and durability, you can expect your tankless water heater to pay for itself within two to three years.  In fact, it should pay for itself at least ten times during its long life, depending on your usage habits.
