US calculator
Water Heater Replacement Cost Calculator
Estimate installed US residential tank-style water heater replacement costs by capacity, fuel type, installation, and access.
How this estimate is calculated
Tank capacity scales the reviewed installed tank-style replacement range. Fuel and equipment type scale with capacity, while installation modifications, access, permits, venting, utility upgrades, and removal are separate fixed project allowances. Installation labour already represented in the baseline is not added again.
This is a planning estimate, not a contractor quote. Actual contractor quotes vary by location, specification, site conditions, labour, and project requirements.
Useful cost information
Planning assumptions
- This models tank-style replacement; tankless systems are excluded.
- The baseline assumes a normal residential replacement at the existing location.
- Select electrical or gas-line work only when additional modification is required.
