What drives the price
- Tank vs. tankless, and gas vs. electric
- Sizing for cold winter inlet water

- Gas line or electrical service upgrades
- Permits, haul-away and code updates like expansion tanks
- Access in the basement and condition of nearby plumbing
Frequently asked questions
Why do tankless conversions cost more?
Tankless units often need a larger gas line, new venting or more electrical capacity than the tank they replace.
Should I replace before it fails?
A tank that leaks in a finished basement can cause expensive damage. If yours is near the end of its expected life or shows rust or moisture, get a quote before it fails.
