Tankless water heater cost with installation — Lewisville, TX
Last updated: September 24, 2026
What affects the price
When you are shopping for a new water heater, the final cost depends on a few moving parts. First, consider the fuel source—switching from electric to gas or vice versa involves more labor. The capacity you need, measured in gallons, also changes the price tag, as does the physical footprint of the unit in your home. If your current plumbing or venting needs updates to meet modern safety codes, that adds to the work involved. We help you sort through these variables, with exact pricing confirmed free on the call.
