1 An electric water heater can cost $400-$3,000 or more for complete installation of a conventional storage-tank model and $1,800-$4,500 or more for a tankless model (including a 220V/240V outlet). 2  Electric water heaters typically cost less than gas units but are more expensive to operate.
The total installation cost may vary depending on the type of tankless water heater that is installed and the professional who installs it. 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. For example, a Noritz gas tankless hot water heater of 199,000 BTUs is sufficient for an average household with several bathrooms. Factors such as installing proper ventilation to prevent carbon monoxide poisoning and completely changing the size of gas lines and fittings will take an average of 10 hours.
