The cost to replace a water heater is typically $900 to $3,000 installed, with a national average of about $1,400 for a standard tank ^[1]. HomeAdvisor reports a similar $1,333 average ^[2]. A like-for-like gas or electric tank swap usually lands near the low end; tankless and heat pump models, or any job that changes fuel type or location, push the bill toward $3,000–$4,700 ^{[1] [4]}.

Cost breakdown: what you’re actually paying for

Every hot water heater replacement cost has three parts: the unit, the labor, and the extras (permit, haul-away, code upgrades).

The unit. Big-box shelf prices for name-brand units, checked on November 9, 2026:

• 50-gallon electric tank (Rheem Performance): $599 ^[9]
• 40-gallon natural gas tank (Rheem Performance): $649 ^[10]
• 50-gallon hybrid heat pump (Rheem Performance Platinum): $1,699 ^[11]
• 199,000 BTU indoor gas tankless (Rinnai RE199iN): $1,280.79, on sale from $1,423.10 ^[12]

Labor. Plumbers charge roughly $45–$200 per hour ^{[1] [2]}. HomeAdvisor estimates labor alone at $150–$450 for a standard tank, $600–$1,900 for a tankless unit, and $150–$2,500 to convert from tank to tankless ^[2]. Fixr says labor ranges from 18% to 50% of the total project, or about $300–$1,500 ^[1]. The spread is mostly about complexity. A straight swap of the same size and fuel in an open basement is quick. A new vent run, gas line, or electrical circuit is not.

Extras. Removing the old tank costs $75–$500 when it’s billed separately ^[1]. Permits usually run $25–$300 ^[2]. Depending on local code, an inspector may also require an expansion tank ($90–$350 plus labor) ^[2].

Unit price vs. labor: our combined estimate

Aggregator ranges are wide because they mix cheap and premium units, easy and hard installs. To make them more useful, we paired a real retail unit price with the labor estimates from the sources above. This table is our own calculation. It excludes permits and removal, so add $100–$800 for those ^{[1] [2]}.

Two takeaways. First, labor is often as big as the unit itself, or bigger. ENERGY STAR’s rule of thumb is that installing a heat pump water heater may roughly equal the unit’s cost ^[5]. Second, the combined figures line up with the aggregator ranges. Our heat pump estimate of $2,699–$4,699 sits close to Angi’s normal range of $3,200–$4,700 ^[4], which suggests the published ranges are realistic, not inflated.

Tankless conversions can also add installation materials ($130–$280, plus about $10 per linear foot of piping), a vent kit ($40–$100), and up to about $1,000 to adapt or add a gas line ^[3].

Tank vs. tankless

A tank installed costs about $600–$2,500, compared with $1,000–$4,000 for tankless ^[1]. The tankless premium buys a longer life (about 15–20 years vs. 8–12 for a tank) and endless hot water ^[1]. The catch is installation. A whole-house gas tankless unit usually needs more gas supply than an old tank. It may also need new venting, and that is where the “up to $1,000” gas line work comes in ^[3]. Electric tankless units can require a power source conversion ($200–$400) or a larger circuit ^[3].

If your current tank is working and you’re only weighing a switch, the tankless math depends on how long you’ll stay in the home. Plan to stay long enough for the extra lifespan to count.

Gas vs. electric

The installed ranges for gas and electric tanks overlap: $700–$2,700 for natural gas and $500–$3,500 for electric ^[1]. Electric tanks generally need no venting ^[2]. Gas tanks may need a power-vent system ($300–$1,100) if they can’t vent through an existing flue ^{[1] [2]}.

The real cost jump comes from switching fuels. Going from electric to gas means running a gas line and venting. Going from gas to electric may mean a new 240-volt circuit or even more panel capacity ^[5]. HomeAdvisor notes that switching fuel types significantly increases the cost of the job ^[2]. For the cheapest replacement, stay with the fuel and size you already have.

Heat pump water heaters

A heat pump (hybrid) water heater moves heat from the surrounding air into the tank instead of making heat directly. It is the most efficient electric option. ENERGY STAR estimates a family of four saves about $550 a year compared with a standard electric tank, assuming $0.146/kWh electricity. A two-person household saves about $270 a year ^[6]. Rheem’s own listing claims up to $315 a year for its 50-gallon hybrid ^[11]. Savings vary with household size and local power rates, so treat any single figure as a ballpark.

Installed cost is about $3,200–$4,700 in Angi’s normal range ^[4], with Fixr and HomeAdvisor reporting lower floors of $1,200 ^{[1] [2]}. ENERGY STAR lists the unit at $1,500–$3,000 and installation at $1,000–$3,000 ^[5]. Before you buy, check three site requirements ^[5]:

• 240-volt power at the install location, with a new circuit if it isn’t there.
• About 450 cubic feet of surrounding air, roughly an 8×8 ft room, or a louvered door on a smaller closet.
• A condensate drain. A floor drain in a garage or utility room is easiest. Elsewhere, the contractor has to route it.

Is the federal 25C tax credit still available?

No, not for water heaters installed in 2026. The Energy Efficient Home Improvement Credit (Section 25C) used to cover 30% of the cost of a qualifying heat pump water heater, up to $2,000 a year ^[7]. The One, Big, Beautiful Bill (Public Law 119-21, signed July 4, 2025) ended it early. The IRS confirms that “the credit will not be allowed for any property placed in service after December 31, 2025” ^[8]. The IRS credit page now describes eligibility only for property placed in service from 2023 through 2025 ^[7].

If you installed a qualifying unit in 2025, you can still claim it on your 2025 return, subject to the IRS rules, including the manufacturer identification number requirement for 2025 property ^[7]. For 2026 installs, look instead to utility and local programs. ENERGY STAR notes that utilities and municipalities often offer $300–$1,000 ^[5], though amounts and availability change frequently.

Some contractor and aggregator pages still advertise the federal credit. If a quote subtracts a “30% federal tax credit” from a 2026 install price, ask the contractor to remove it.

Worked example: replacing a 50-gallon electric tank, family of four

Say a four-person household’s 50-gallon electric tank has failed, and the heater sits in a garage with a floor drain and an existing 240-volt circuit. Here are the two common choices, built from the figures above:

At the midpoints, the heat pump costs about $2,200 more up front. ENERGY STAR estimates this household saves about $550 a year ^[6], which pays back the difference in roughly four years. That’s longer than ENERGY STAR’s own 2.7-year figure, which assumes a smaller $1,503 price gap ^[6]. Higher electricity rates shorten the payback.

Two notes. No federal credit applies in 2026. Under the old 25C rules, this install would have earned up to 30% back, capped at $2,000 ^{[7] [8]}. And if this home lacked a 240-volt circuit or a nearby drain, the heat pump total would rise. That is exactly what pushes real quotes toward the top of the range.

Ways to save

• Replace like-for-like. Same fuel, same size, same spot is the cheapest job, because it avoids gas line, venting and electrical work ^[2].
• Ask whether haul-away and the permit are included. Removal alone can be $75–$500 when it’s itemized ^[1].
• Get at least three quotes, and compare the unit model and warranty as well as the total. A 6-year and a 12-year tank are not the same product.
• Check utility rebates before you buy a heat pump unit. Local programs are now the main incentive ^[5].
• Don’t wait for a failure. If your tank is near the end of the 8–12 year range ^[1], replacing it on your schedule avoids emergency rates, which can run $100–$500 per hour ^[3].

Hiring a pro

Water heater replacement involves gas connections, 240-volt wiring, or both, plus a pressure relief valve that has to be installed correctly. Hire a licensed plumber for the job. For heat pump or electric tankless conversions, the plumber may also need a licensed electrician ($50–$100 per hour) ^[2]. Make sure the quote states who pulls the permit and whether it covers code-required parts such as an expansion tank. Those items explain most of the gap between two quotes for the same water heater.
