$1,300 to $1,800 is the range most sites quote as the national average for water heater replacement, but that figure almost always describes a basic tank swap alone. Add a tankless or heat pump unit and published ranges span $881 to $6,000 installed, which is why one average rarely fits one job.
Hot Water Brief is an independent cost-research site. We are not a contractor and do not perform the work ourselves.
That $1,300 to $1,800 band is not wrong, it is just narrower than the question sounds. Three of the pages that rank for this exact search each publish their own single average, and none of them agree, because each is quietly built on a different scope. The table below shows what each one actually measured, with its own date.
| Publisher | Published range | Published average | What the headline actually covers | Dated |
|---|---|---|---|---|
| Angi | $881 to $1,826 | $1,346 | General replacement headline; tankless is quoted separately at $1,400 to $3,900 | Updated July 20, 2026 |
| Fixr | $900 to $3,000 | about $1,400 | Stated in the same paragraph to price a natural gas, tank water heater | Updated January 27, 2026 |
| Homewyse | $1,586 to $1,843 | about $1,715 (midpoint) | A 40 gallon gas tank swap only, no other type priced on this figure | May 2026 |
None of the three headline numbers is pricing tankless, heat pump, or a large tank against a like-for-like swap. That is not an error in any one source, it is a mismatch between the question people type and the answer a headline gives them.

They disagree because each headline number quietly narrows the question. Angi's opening average of $1,346 is the same range, $881 to $1,826, that the same article later labels tank-style only. Fixr's $900 to $3,000 headline is stated, in the same paragraph, to price a natural gas, tank water heater. Homewyse prices one specific 40 gallon gas tank swap.
None of the three publishes a stated blend ratio of tank to tankless, or gas to electric. What gets called the average cost of water heater replacement is, in practice, the average cost of the single most common job, a tank replacing a tank. Tankless, heat pump and any size upgrade sit outside that number.
The published tank-only averages leave out tankless and heat pump equipment, both of which cost substantially more installed. A gas tankless install runs $3,293 to $3,859, and a heat pump water heater runs about $2,500 to $6,000 fitted, against $1,586 to $1,843 for a like-for-like 40 gallon gas tank swap, all sourced separately below.
Those figures reuse this site's already sourced data: Homewyse's tankless gas estimate, dated May 2026, and ENERGY STAR's heat pump guidance, dated February 2, 2024, pricing equipment at $1,500 to $3,000 and installation at $1,000 to $3,000. Neither appears in a headline average built from tank jobs, and Angi's own article notes about 90 percent of households have a tank-style unit, which is why a blended average gravitates toward the tank price.
It is close only if your job is a straightforward, like-for-like tank swap with no permit, no expansion tank, and no vent or electrical change. Homewyse's own national tank estimate of $1,586 to $1,843 excludes permit and inspection fees, sales tax, and contractor overhead of 13 percent to 22 percent.
Move outside that narrow job, a tankless conversion, a larger tank, a fuel switch, an aging panel, and the published average stops applying, because none of the three headline figures priced those variables in. It answers what the most common job costs, not what your specific job will cost.
The number that matches your job depends on the type of unit and fuel you are replacing. The full cost breakdown covers tank, tankless, heat pump, gas and electric pricing with sourced ranges for every combination, and three dedicated guides go deeper on the most searched segments below.
Each page sources its figures the same way this one does, so once you know your job, it gets you closer to a real number than a single average can.
Every figure above is listed here with its publisher and date. If a number is not traceable to this list, it is not on this page.
Prices move. The dates above are the point of the exercise, so check them against the day you are reading this rather than assuming any figure above still holds.
Published national averages cluster between $1,300 and $1,800. Angi states $1,346, range $881 to $1,826, updated July 20, 2026. Fixr states about $1,400, range $900 to $3,000, updated January 27, 2026. Both price a basic gas tank swap, not tankless or heat pump equipment.
Because each blends a different set of jobs without saying so. Angi's headline number matches its own tank-style figure quoted later in the article. Fixr's $900 to $3,000 headline prices a natural gas tank water heater. Homewyse prices one 40 gallon gas tank swap at $1,586 to $1,843, dated May 2026.
No. A gas tankless install runs $3,293 to $3,859, and a heat pump water heater runs roughly $2,500 to $6,000 fitted, per Homewyse and ENERGY STAR, dated May 2026 and February 2, 2024. Neither sits inside the $1,300 to $1,800 headline averages, which price tank jobs only.
Not fully. Homewyse's national tank estimate of $1,586 to $1,843, dated May 2026, excludes permit and inspection fees, sales tax, and contractor overhead of 13 to 22 percent. Removal is priced separately at $84.87 to $267, so scope, not price alone, decides the comparison.
Start with the full cost breakdown at /cost/, covering tank, tankless, heat pump, gas and electric pricing with a source and date on every figure. Dedicated guides linked above go deeper on tank swaps, gas-specific pricing, and tankless unit versus installed pricing.
Not necessarily, it depends on scope, not price alone. Homewyse's figures exclude permit fees, sales tax and 13 to 22 percent contractor overhead. A lower quote excluding those items is not automatically the better deal, nor is a higher one that includes them automatically worse.
