How much does a tankless water heater cost in Kitsap?
Answer first: Eagle Pipe’s published installed range for tankless water heater installation is $5,437–$7,300. Gas line capacity, venting, condensate, and permits often matter as much as the unit itself — dual-licensed HVAC + plumbing coordination helps when mechanical rooms share systems.
