Use an installed-price benchmark, then compare the scope that makes your own replacement quote higher or lower.

Start with installed cost, not the appliance shelf price.
$1,600–$2,400
A starting reference for a basic replacement.
$2,400–$5,400
Conversion work can change the total substantially.
$2,500–$5,000
Check the site requirements and electrical scope.
Source: The Home Depot’s U.S. installation cost guide, checked October 9, 2026. These are one provider’s published ranges, not a Field 52 price survey or a quote for your home. The provider lists equipment, installation, permits and removal in its estimates. Confirm those inclusions in your own written quote.
A difficult site or a system conversion can fall outside these ranges. Do not use the low end as a promise, or add a separate appliance price to a quote that already includes the heater.
Compare the work before comparing the totals.
Ask whether the new model fits the existing location and whether the quote includes any required connection changes. The same gallon rating does not guarantee identical dimensions or connections.
A tankless conversion, a change of fuel, or a heat pump installation needs its own site assessment. Request separate line items for electrical work, venting, drainage and other enabling work that applies.
Tell the estimator about stairs, tight doors, attic or crawlspace access and any move to another room. Ask who repairs disturbed finishes.
Have the installer identify applicable permits and inspections. Ask which required changes are included and which could become a change order.
Ask both bidders to price the same outcome.
Record the exact model, fuel, delivery rating and equipment warranty. Compare an equivalent hot-water service level, not just nominal tank volume.
Request labor, removal, permit handling, required connections, commissioning and site cleanup. Identify exclusions explicitly.
Keep an elective relocation or added convenience feature distinct from required work. Ask for the reason behind each proposed upgrade.
Separate the contracted price from any potential rebate. Verify a program’s current eligibility and funding before treating it as money received.
If the heater is repairable, compare both paths.
A replacement quote is only half the repair-or-replace decision. Ask for a diagnosed repair scope, its warranty and whether it addresses the reported problem. Then compare that with the complete replacement scope.
If switching systems is the goal, use Tank vs. Tankless before committing to a price. A lower quoted cost is not useful if the proposed system cannot meet the household’s peak demand.
Cost questions worth asking.
Is the cheapest unit the cheapest replacement?
Not necessarily. Compare the complete installed job and the expected service, not equipment price alone.
Are incentives included in these ranges?
Do not assume so. Keep incentives separate until the program administrator confirms eligibility and the payment conditions.
Should I request an exact price online?
An online figure can help with planning. A binding scope should account for the actual equipment, access and installation requirements.
