Last updated: October 2026
Replacing a standard tank water heater usually costs $600 to $3,100 installed. Most homeowners pay about $1,300 to $1,950 on average for the unit, labor, permit and haul-away. A tankless unit runs $1,400 to $5,600 installed, and a hybrid heat pump water heater $2,000 to $4,600. The biggest swings come from fuel type (gas or electric), tank size, and any code upgrades your home needs to pass inspection.
Below you’ll find current price tables from national cost databases and retailer data, the add-on charges that turn a $1,200 quote into a $2,500 one, how prices vary by region, and when repairing your old unit is the better call.

How much does a new water heater cost by type?
The type of heater you choose is the single biggest driver of your total. Here’s what the unit alone typically costs versus the installed price.
| Type | Unit only | Installed | Typical lifespan |
|---|---|---|---|
| Standard tank (gas or electric) | $400 – $2,100 | $600 – $3,100 | 8–12 years |
| Tankless (on-demand) | $600 – $2,600 | $1,400 – $5,600 | 15–20+ years |
| Hybrid heat pump | $1,500 – $3,000 | $2,000 – $4,600 | About 13 years (ENERGY STAR estimate) |
| Indirect (boiler-fed) | $1,500 – $3,000 | $1,200 – $4,500 | Varies with boiler |
| Solar | $1,000 – $6,000 | $1,700 – $9,000 | Varies |
Unit-only and installed ranges come from HomeGuide (January 2026), with installed indirect and solar ranges cross-checked against Fixr and Angi. Lifespans are from Rheem and ENERGY STAR.
If you’re weighing an upgrade rather than a straight swap, our guides to tankless water heater cost, heat pump water heater cost and tankless vs tank water heaters go deeper.
Water heater replacement cost by tank size
Bigger tanks cost more to buy, and 75- and 80-gallon units are heavier and may need a second installer or floor reinforcement. Sources differ a little, so we show the overlap.
| Tank size | Best for | Unit only | Installed |
|---|---|---|---|
| 30 gallons | 1–2 people | $300 – $900 | $500 – $2,100 |
| 40 gallons | 2–4 people | $400 – $2,000 | $550 – $3,000 |
| 50 gallons | 3–5 people | $500 – $2,100 | $700 – $3,100 |
| 65 gallons | 4–6 people | $700 – $2,400 | $900 – $3,400 |
| 75 gallons | 4–6 people | $900 – $2,600 | $1,100 – $4,000 |
| 80 gallons | 6+ people | $1,000 – $3,000 | $1,200 – $4,000+ |
Ranges blend HomeGuide, Fixr and Angi data. Angi’s upper figure for 80-gallon installs reaches $7,500, which reflects premium heat pump or high-efficiency gas models.
The 50-gallon tank is the most common size in American homes. For model-by-model pricing see our 50-gallon water heater replacement cost guide. If you’re unsure whether to size up or down, read what size water heater do I need. Buying too small means running out of hot water, and buying too big means paying to keep extra water hot.
Gas vs electric water heater replacement cost
A like-for-like electric tank swap is usually the cheapest replacement. Gas units cost a bit more to install because the plumber also has to reconnect the gas supply, check the venting and test for leaks and proper draft.
| Fuel | Installed cost (tank) | Labor | Estimated yearly running cost |
|---|---|---|---|
| Electric tank | $600 – $1,900 | $150 – $600 | $530 – $720 |
| Natural gas tank | $700 – $3,100 | $200 – $1,000 | $250 – $575 |
| Propane tank | $700 – $2,500 | Similar to gas | Higher than natural gas |
| Hybrid heat pump (electric) | $2,000 – $4,600 | $500 – $1,600 | $160 – $190 |
Installed costs come from HomeGuide, Fixr and Angi. Running costs are estimates from HomeGuide and Fixr and depend heavily on local utility rates and how much hot water you use.
We cover fuel choice, conversion costs and running costs in our gas vs electric water heater replacement cost comparison.
Full cost breakdown: what’s in a water heater replacement quote
A good quote lists each of these items. If yours shows a single lump sum, ask the plumber to break it down so you can compare it with other bids.
1. The water heater itself
Expect to pay roughly $400 to $2,100 for a standard 40- or 50-gallon tank. Big-box retailer shelf prices for basic 50-gallon electric tanks currently start in the mid-$500s, and natural gas models start in the $700s. Longer warranties (9–12 years instead of 6), higher efficiency ratings and smart features push the price up.
2. Labor
Plumbers typically charge $45 to $200 per hour, with most tank swaps taking 2 to 4 hours. Total labor for a standard tank replacement usually lands between $150 and $1,000. Gas units sit at the higher end because of venting and gas work. Emergency, weekend and after-hours calls often add a 25% to 50% premium (HomeGuide).
3. Permits and inspection
Most US jurisdictions require a permit to replace a water heater, especially a gas unit. Fees usually run $25 to $300, but jobs that involve new gas lines or electrical work can need several permits. Fixr notes combined permit costs can reach $1,500 in some cases. Your plumber should pull the permit and schedule the inspection.
4. Removal and disposal of the old unit
Draining, disconnecting and hauling away the old tank costs $75 to $500 when it’s billed separately. Many plumbers, as well as Home Depot’s and Lowe’s installation programs, include haul-away in the base price.
5. Code upgrades
Codes have changed a lot over the life of a 10- or 12-year-old heater, so your replacement may need upgrades to pass inspection:
| Code item | Typical cost | When it’s needed |
|---|---|---|
| Thermal expansion tank | $40 – $450 installed | Homes with a pressure-reducing valve, check valve or backflow preventer (a “closed” water system). Many local codes now require one. |
| Seismic/earthquake straps | $100 – $300 | Required statewide in California and in many other seismic zones |
| Drain pan and drain line | $50 – $200 | Required by many codes when a leak could damage the building, such as attics, upper floors and finished spaces |
| Temperature and pressure (T&P) relief valve and discharge pipe | $20 – $200 | Every tank must have one, piped to a safe location |
| Venting corrections (gas) | $100 – $600 to modify, $500 – $1,500 for new venting | Undersized, damaged or non-compliant flue |
| Chimney liner (gas) | $500 – $700 | When the water heater vents into an old masonry chimney |
| General code compliance | $75 – $500+ | Shutoff valves, gas sediment trap, bonding, and similar items |
Ranges come from HomeGuide, This Old House (Home Depot data) and Angi.
6. Gas line and electrical work
- Gas line upgrade or new run: $260 to $2,000. A short extension is at the low end, and a new line from the meter is at the high end. Tankless gas units often need a larger 3/4-inch line.
- New dedicated 240V circuit: $250 to $900. You’ll usually need one when switching from gas to an electric tank or a heat pump unit.
- Electrical panel upgrade: $850 to $3,000. This only applies if your panel can’t handle the extra load, which is common with whole-home electric tankless.
7. Relocation or conversion
Moving the heater to a new spot costs $150 to $3,400, depending on how much pipe, venting and wiring has to be rerouted. Fuel switching typically costs $400 to $2,000+ for electric-to-gas and $250 to $1,000+ for gas-to-electric (HomeGuide). It can climb past $3,500 if you need a new gas service. Tank-to-tankless conversion adds $600 to $2,500 in labor on its own.
What makes water heater replacement cost more (or less)
- Like-for-like vs change: Same fuel, same size and same location is always the cheapest job. Changing any of those adds labor and materials.
- Access: Attic installs add $200 to $1,000. Tight closets and crawlspaces add time, and basement installs with stairs may need two people for an 80-gallon tank.
- Venting type: Atmospheric (standard) gas venting is cheapest. Power-vent units cost $300 to $600 more and need an outlet nearby. Direct-vent units need an exterior wall penetration.
- Age of the home: Older homes are more likely to need expansion tanks, new shutoff valves, flue repairs or gas line corrections to meet current code.
- Brand and warranty: Basic retail brands start around $350 to $1,000 for the unit. Contractor-grade lines from Rheem, A.O. Smith and Bradford White range up to $2,300 to $3,500 (Angi).
- Timing: A burst tank on a Sunday night costs more than a planned replacement on a Tuesday morning.
- Water damage: If the old tank leaked, drywall and flooring repairs can add $500 to $5,500+. Check our water heater leaking guide for what to do right away.

Labor rates and permit fees track local cost of living, so the same 50-gallon gas swap can cost hundreds more in a coastal metro than in the Midwest. Home Depot’s installation data, as reported by This Old House in 2026, puts regional prices relative to its ~$1,950 national average like this:
| Region | Versus national average | Approximate installed cost |
|---|---|---|
| Pacific Northwest | Up to 45% higher | Up to ~$2,800 |
| Gulf Coast | 10% – 20% higher | ~$2,150 – $2,350 |
| Mid-Atlantic and Midwest | 5% – 10% lower | ~$1,750 – $1,850 |
| South Florida | About 20% lower | ~$1,550 |
City-level averages compiled by Angi/HomeAdvisor and published by Bob Vila show the same pattern:
| City | Average replacement cost |
|---|---|
| Austin, TX | ~$1,300 |
| Phoenix, AZ | ~$1,300 |
| Dallas, TX | ~$1,400 |
| Philadelphia, PA | ~$1,500 |
| Chicago, IL | ~$1,600 |
| New York, NY | ~$1,800 |
| Los Angeles, CA | ~$1,900 |
| San Diego, CA | ~$1,900 |
These city figures date from 2024 data, so treat them as relative guides and add a few percent for inflation. HomeGuide notes that San Francisco, New York and Seattle are among the most expensive markets. Rural areas can also run higher than you’d expect because of travel time and fewer contractors.
Ways to save on a water heater replacement
Check rebates, and know the federal tax credit has ended
The federal 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, and up to $600 for a qualifying high-efficiency gas, propane or oil water heater. The One Big Beautiful Bill Act, signed in July 2025, ended the credit for property placed in service after December 31, 2025, and the IRS describes it as applying to property placed in service from 2023 through 2025. A water heater installed in 2026 does not qualify. If yours was installed and working by December 31, 2025, you claim it on your 2025 return using Form 5695.
Other savings are still available:
- State home electrification rebates (HEEHRA/HEAR): These are funded by the 2022 Inflation Reduction Act and run by individual states. They can pay up to $1,750 toward a heat pump water heater for households earning up to 150% of area median income. Availability varies widely by state. Some programs are open, some have waitlists, and some states haven’t launched. Check your state energy office’s website.
- Utility rebates: Many electric and gas utilities offer rebates, often $100 to several hundred dollars and sometimes more for heat pump units. Search your utility’s website or the ENERGY STAR rebate finder.
- Manufacturer and retailer promotions: Seasonal sales and installation promotions at big-box stores can cut the unit price.
Other practical ways to cut the bill
- Replace before it fails. A planned replacement avoids emergency rates and water damage.
- Get at least three written quotes that list the unit model, permit, haul-away and code items.
- Stick with like-for-like unless an upgrade pays for itself. Switching fuel or moving the heater adds hundreds to thousands of dollars.
- Size correctly. A 40-gallon tank may be enough for a couple, while a family of five may need 50 to 65 gallons.
- Ask about price matching. Home Depot and Lowe’s both advertise installation price-match guarantees, with conditions.
- Maintain the new heater. Annual flushing and anode checks help it reach the long end of its lifespan. See how to flush a water heater.
Repair or replace your water heater?
Typical water heater repairs cost about $230 to $1,000, with many simple fixes (thermostat, heating element, gas valve or anode rod) at the low end. Our water heater repair cost guide has the details. Use these rules of thumb, drawn from Rheem’s guidance and the cost data above:
| Repair is usually worth it if… | Replace if… |
|---|---|
| The unit is under 6–8 years old | The tank is 10+ years old (8–12 years is a normal tank lifespan) |
| The problem is a part: element, thermostat, igniter, thermocouple, gas valve, T&P valve | Water is leaking from the tank body itself |
| A fitting or valve is leaking, not the tank | You see rust-colored hot water or corrosion at the base |
| The repair costs well under half of a new unit | The repair costs 50% or more of a replacement |
| It’s the first problem in years | You’ve needed several repairs in a short period |
A leaking tank can’t be repaired. Once the steel lining corrodes through, replacement is the only fix. To estimate how much life your unit has left, see our water heater lifespan guide. Your heater’s age is usually encoded in the first characters of the serial number on the rating label.
DIY vs professional water heater replacement
Doing it yourself can save $150 to $1,000 in labor, but it’s not a casual weekend project, particularly with gas.
- Permits still apply. Most jurisdictions require a permit and inspection even for homeowner installs, and some only let licensed plumbers do gas work.
- Gas safety: Incorrect gas connections or venting can cause leaks or carbon monoxide backdrafting. If you’re not experienced with gas fittings, leak testing and draft testing, hire a pro.
- Electrical safety: Electric tanks run on 240V circuits. Turning on the power before the tank is full will burn out the heating elements instantly.
- Weight: A 50-gallon tank weighs over 100 pounds empty, and old tanks often hold sediment.
- Warranty and insurance: Some manufacturers require professional installation for full warranty coverage, and an unpermitted install can cause problems with insurance claims or when you sell the home.
A competent DIYer with plumbing experience can handle a like-for-like electric swap. For gas, tankless and heat pump units, or anything requiring new venting, wiring or gas lines, a licensed plumber is the safer and often legally required choice.
How to hire a plumber for water heater replacement
- Check the license. Verify the plumber’s state or local license online, and confirm general liability insurance.
- Get three itemized, written quotes. Each should list the exact make, model, capacity and warranty of the heater.
- Read recent reviews on several platforms, looking specifically for water heater jobs.
- Confirm who pulls the permit. It should be the contractor.
- Get the labor warranty in writing. One year is common, and some installers offer more.
Questions to ask before you sign
- Does the price include the permit, inspection, haul-away and disposal?
- Will my home need an expansion tank, drain pan, seismic straps or venting changes to pass code? Are those in the quote?
- What brand and model are you installing, and what’s the tank and parts warranty?
- How long is your labor warranty?
- Will you set the thermostat to 120°F (the setting recommended by the DOE for most homes) and show me the shutoff valves?
- How soon can you do the work, and is there an extra charge for same-day service?
- What happens if you find a problem, like a corroded gas line or bad shutoff valve, once you start?
FAQs
How much does it cost to replace a water heater?
Most homeowners pay $600 to $3,100 to replace a standard 40- or 50-gallon tank water heater, with national averages reported between about $1,300 and $1,950. Tankless replacements cost $1,400 to $5,600, and hybrid heat pump units $2,000 to $4,600 installed.

A 50-gallon tank typically costs $700 to $3,100 installed. The unit alone is about $500 to $2,100. Electric models are usually cheaper to buy and install than gas, and heat pump models cost the most upfront.
Is it cheaper to replace a gas or electric water heater?
An electric tank is usually cheaper to replace ($600 to $1,900 installed) than a gas tank ($700 to $3,100), because there’s no venting or gas connection. Gas is often cheaper to run each month, though, depending on local utility rates.
How long does it take to replace a water heater?
A like-for-like tank replacement usually takes 2 to 4 hours. Home Depot quotes 2 to 3 hours for a tank-to-tank swap. Switching to tankless or changing fuel can take a full day or more.
How often should a water heater be replaced?
Tank water heaters typically last 8 to 12 years, and tankless units 15 to 20+ years. Hard water, lack of flushing and high thermostat settings can shorten that.
Does homeowners insurance cover water heater replacement?
Standard homeowners policies generally don’t pay to replace a heater that failed from age or wear. They may cover sudden water damage the leak caused. Policies vary, so check yours, and note that home warranty plans are separate products with their own limits.
Is there a tax credit for a new water heater in 2026?
No federal tax credit is available for water heaters installed in 2026. The 25C credit, worth up to $2,000 for heat pump water heaters, ended for property placed in service after December 31, 2025. State rebates and utility incentives may still be available.
Do I need a permit to replace a water heater?
In most US cities and counties, yes, especially for gas water heaters. Permits typically cost $25 to $300, and a licensed plumber will usually pull it for you and arrange the inspection.
Should I replace my water heater before it breaks?
If your tank is past 10 years old, planning a replacement is often smart. You avoid emergency service premiums, water damage and days without hot water, and you have time to compare quotes.
Why do water heater quotes vary so much?
Quotes differ by the brand and warranty of the unit, local labor rates, whether permit and haul-away are included, and whether the plumber has priced in code upgrades like an expansion tank or venting changes. Itemized quotes make the differences clear.
