How much does a tankless water heater cost?

Tankless water heaters produce hot water on demand when you turn on a faucet, which is why they are also called on-demand water heaters or instantaneous water heaters.

While tankless water heaters may cost more up front than tank water heaters, they tend to last longer. Therefore, the cost of a tankless water heater, if maintained properly, could be less over the life of the unit.

See this explainer on how tankless water heaters work.

    Cost will vary depending on the contractor and type of system you're installing. Contact a local, licensed plumber for an estimate.

Additional Costs for Installing a Tankless Water Heater

  • A 200 AMP electrical outlet may be needed for an electric tankless water heater to work in your home. This will add to the total cost of installation.

  • If you're installing a tankless water heater in a new home, the appropriate pipes and ventilation can be installed prior to or during the time that your tankless water heater is being installed. If your tankless water heater needs to be retrofitted into a home that originally had a tank water heater, the installation effort is greater, and therefore, the cost will be higher.
