Quick answer
The cost of replacing a water heater depends mostly on the type (tank or tankless), fuel (electric or gas), capacity, how hard the location is to work in, and any updates needed to meet current code. Repair is usually the better value when the tank is sound and the failed part is replaceable.
The biggest cost factors
- Tank vs. tankless — tankless costs more up front
- Electric vs. gas, and whether venting or gas lines need changes
- Size/capacity for your household
- Location — garage, closet, attic, or exterior
- Code-required parts like expansion tanks, pans, or valves
- Haul-away of the old unit
Repair or replace?
Repair: tank isn't leaking, unit is mid-life, a single part failed. Replace: tank body is leaking, repeated repairs, rusty water, or it no longer keeps up. See water heater repair & replacement.
