What Should a Water Heater Replacement Cost?
A water heater usually fails without warning, which makes it the quote homeowners are least able to shop around for. Here are the published national numbers, what actually moves the price, and how to check the quote in front of you.
The national numbers
| Job | Low | Typical | High |
|---|---|---|---|
| Water heater replacement (tank-style, installed) | $881 | $1,348 | $1,826 |
Source: Angi, "How Much Does Water Heater Replacement Cost? [2026 Data]" (page updated October 16, 2026; fetched November 3, 2026). Angi puts the national average at $1,348, with most homeowners paying between $881 and $1,826 for a tank-style replacement.
Going tankless is a different job with a different price: the same guide puts tankless systems at $1,400–$3,900. Note that this is a range without a published national average — if your tankless quote is being compared against the tank numbers above, the comparison itself is wrong.
What moves the price inside that range
- Like-for-like vs. conversion. Swapping a tank for a similar tank is the cheapest version of this job. Changing fuel type, size, or switching to tankless moves you up the range or out of it entirely.
- Code upgrades. An older installation may predate current code. Work required to bring the new install up to code is a legitimate cost — but it should appear as its own line, so you can see it.
- Access and location. A heater in an open garage is not the same job as one in a tight closet or attic.
- Timing. A no-hot-water emergency on a weekend is the worst negotiating position there is. If the heater is aging but still working, getting quotes before it fails is the single cheapest move available.
What a complete quote should include
- The new unit — make, model, tank size, and warranty.
- Labor for removal of the old unit and installation of the new one.
- Disposal or haul-away of the old heater.
- Permit fees, where required.
- Any code-upgrade work, itemized separately rather than folded into one lump sum.
- Parts the job needs — valves, venting, pans, fittings — listed, not bundled into a mystery line.
Worked example: a $1,600 quote for a like-for-like tank replacement sits inside the $881–$1,826 range, 19% above the $1,348 national average. Nothing about that number alone is a red flag — what matters is whether the lines above are all there.

They are not a guarantee of what your replacement should cost locally; tank size, fuel type, code requirements, and access all move the real price.
