Quick answer
Tankless (on-demand) water heaters heat water as you use it. They can free space and reduce standby loss, but they need correct gas capacity or electrical service, proper venting, and water-quality planning. Eagle's published tankless install range is $5,437–$7,300 — final price follows on-site diagnosis under the No Price Change Guarantee.
- Gas line size and venting drive many tankless scopes — not just the unit price.
- Hard water and sediment shorten heat-exchanger life without flush maintenance.
- Published install range: $5,437–$7,300 (transparent pricing).
- Dual-licensed HVAC + plumbing shops can coordinate shared gas/mechanical work cleanly.
When tankless is on the table
Your tank is failing, you're remodeling a mechanical room, or a quote pushed tankless without explaining gas upsizing. Compare against tank and heat-pump water heater paths before you decide.
How it works
Install realities
A proper tankless job confirms fuel delivery, combustion air/vent path, condensate (for condensing units), isolation valves for flushing, and code permits through the correct AHJ (city vs Kitsap County vs Jefferson County).
Unit-only pricing
A bid that prices only the heater and ignores gas, vent, or permits is not comparable to a complete licensed install. Use the quote checklist before you sign.

Common questions
Do I need a recirculation line?
Not always. Recirc improves wait times in larger homes but adds complexity and energy use. We discuss demand vs comfort before adding it to scope.
