1 Because tankless water heaters require a 220V/240V electrical outlet or larger gas pipes than found in an average home plus a stainless steel ventilation system, installation can add $1,000-$3,000 or more, bringing total costs to $1,800-$4,500.

Understanding what type of tankless water heater to install is the next step. Consumers should choose the type of tankless water heater that is best suited to their needs.
