Typical installed cost (standard tank heater)
$1,200 – $2,500
Most homeowners replacing a standard 40 to 50 gallon tank heater fall in this range. Tankless and heat pump models cost more upfront. Your price depends on your home, your city and local code requirements.
Water Heater Replacement Cost by Type
These are general estimates for a typical single-family home. They include the unit and installation, but not every extra your home might need.
| Type | Typical installed cost | What changes the price |
|---|---|---|
| Tank, electric (40-50 gal) | $1,200 – $2,500 | Simple swaps are on the low end; tight spaces and wiring changes add cost |
| Tank, gas (40-50 gal) | $1,300 – $2,800 | Venting, gas connections and code updates affect labor |
| Tankless, electric | $2,000 – $5,000 | May need an electrical service upgrade |
| Tankless, gas | $2,500 – $6,500 | May need a larger gas line and new venting |
| Heat pump (hybrid) | $2,500 – $5,500 | Needs space and airflow; some utilities offer rebates |

What Affects Your Water Heater Replacement Cost
Type and size
A larger tank or a tankless unit costs more than a standard 40 or 50 gallon tank. Choose capacity based on household size and hot water use.
Fuel and venting
Switching between gas and electric, or changing the vent route, adds labor and materials.
Location and access
A heater in an attic, crawlspace or tight closet takes more time to remove and install than one in a garage.
Permits and code updates
Many cities require a permit. Older installs may need an expansion tank, a drain pan, updated venting or seismic strapping where required.
Removal and disposal
Hauling away the old heater is often included, but ask so it does not show up as an extra charge.
Warranty length
Longer parts and labor warranties usually cost more upfront but can protect you if a part fails early.
What a Good Replacement Quote Should Include
When you compare quotes, make sure each one lists the same items so the totals mean the same thing.
- The make, model and capacity of the new heater
- Removal and disposal of the old unit
- New shutoff valves, connectors and a relief valve if needed
- Permit costs and who pulls the permit
- Any code upgrades such as an expansion tank or drain pan
- Parts and labor warranty terms in writing
Compare apples to apples. A quote that looks cheaper may leave out the permit, the expansion tank or disposal. Ask each plumber to price the same capacity and warranty.
Repair or Replace Your Water Heater?
Tank water heaters often last somewhere around 8 to 12 years, and tankless models can last longer with regular care. If yours is older and leaking, rusty or failing repeatedly, replacement usually makes more sense than another repair. For newer heaters with a single failed part, water heater repair may be the better value.
If you are weighing a bigger upgrade, read about tankless water heaters, and see what regular upkeep costs in our water heater maintenance cost guide.
Ways to Lower Your Water Heater Replacement Cost
- Get three written quotes before you decide
- Ask your electric or gas utility about rebates, especially for heat pump models
- Right-size the heater instead of buying more capacity than you need
- Schedule a non-emergency swap if you can, since rush jobs often cost more
- Maintain your next heater so it lasts longer

Do I need a permit to replace a water heater?
Many cities require one, and the plumber usually handles it. Ask each plumber whether the permit is included in the price so you can compare quotes fairly.
