# Water heater replacement costs: compare the full scope

Use a dated US cost reference, then get a local written quote that covers the full job.

Updated 2026-11-10. Also on the [web page](https://plumberpros.fyi/guides/water-heater-replacement-costs).

A water heater price can mean the appliance alone or a complete installed job. Ask which one the quote describes. Do not compare a unit price with an installed price.

## A dated reference, not a quote

This Old House, in its water heater installation cost article accessed 2026-11-10, reports a US average of $1,950. It gives installed tank costs of $1,200 to $2,300 and tankless costs of $2,100 to $4,000. These amounts are US dollars. The article attributes its cost estimates to national averages from The Home Depot. They are broad editorial estimates, not a price offered by any plumber in this directory. Do not add the article's separate component ranges together as if they form a quote.

These figures do not establish a Canadian price. Ask a local contractor for a quote in Canadian dollars for a Canadian job. Do not turn a US range into a Canadian estimate with an exchange rate.

## Give each contractor the same brief

Send the existing model label, fuel type, location and photos of the access route. Ask the contractor to inspect the site before treating a quote as final. Say whether you want a direct replacement or a change in fuel or location. Ask for the proposed model and its capacity rating.

## Compare these lines

- Appliance model and supply cost.
- Removal and disposal of the existing unit.
- Water connections, shutoff valves and required fittings.
- Any gas, electrical or venting work.
- Permit and inspection arrangements for your address.
- Work needed to protect floors and provide safe access.
- Tax, payment schedule, warranty and exclusions.

Do not assume a short quote includes all these items. Ask the contractor to mark each as included, excluded or subject to inspection.

## Control changes

Ask for a written change process before work starts. If the contractor finds a hidden problem, ask for a description, photos where practical, and the price before approving extra work. Keep the original scope and each approved change together.

## Compare operation as well as installation

DOE's Energy Saver guide recommends looking at the EnergyGuide and ENERGY STAR labels when choosing a replacement. Ask the installer to explain how the proposed model fits your use and site. Do not assume a lower equipment price gives the lowest operating cost.

## Questions

### Is this a quote for my home?

No. The dated US figures are background only. Ask a contractor for a written quote for your address and scope.
