National Baseline & Scope Drivers
Replacing a standard tank water heater with a like-for-like unit, installed and hauled away. National planning range for this job sits between $900 and $3,400.
Key Price Drivers for Water Heater Replacement
- Tank versus tankless: A tankless conversion typically doubles or triples the job because it usually requires a larger gas line, new venting, or a substantial electrical upgrade.
- Fuel type: Electric resistance units are cheapest to install. Gas costs more because of venting and gas connection. Heat pump units cost the most up front and save the most to run.
- Code upgrades triggered by the swap: Expansion tanks, drain pans, seismic strapping, a new gas shutoff and updated venting are frequently required on replacement and are commonly excluded from the headline price.
- Access: A garage installation is straightforward. An attic or a finished basement with a tight stairwell adds labor, and attic installations require a pan and a drain line.
- Permit and inspection: Most jurisdictions require a permit for a water heater replacement. Budget $75 to $300 plus the contractor's handling time.
