Price

Cost to install a tankless water heater:

  • Low$4,500
  • Average$7,000
  • High$10,000

What affects cost?

The cost to install a tankless water heater depends on several factors, including:

  • Gas vs electric. A natural gas tankless water heater costs more to install than an electric one. But gas units typically offer lower monthly costs.
  • Whole-home vs "POU" units. A whole-home tankless unit costs more than a single "point of use" unit that only provides hot water for a single appliance.
  • Size of the water heater. Tankless water heaters are sized by their "flow rate" (gallons of hot water it provides per minute). The higher the flow rate, the more expensive the unit.
  • Company you hire. You’ll pay more for skilled, experienced plumbers who know how to properly install your tankless unit.
