Use this water heater replacement cost calculator to estimate the cost of replacing a residential water heater in 2026. Choose the heater type, capacity, replacement conditions and possible upgrades to build a preliminary project budget.
Water Heater Replacement Cost Calculator
Estimate equipment and professional installation costs for a new water heater.
Estimated water heater replacement cost
Preliminary professional-installation estimate based on your selections.
Actual prices vary by heater specifications, capacity, fuel source, existing connections, code requirements and installation conditions.
How This Water Heater Replacement Cost Calculator Works
The calculator starts with the installed price range for the selected water heater type. Standard tank, tankless, hybrid heat pump, indirect and solar systems have different baseline costs because their equipment and installation requirements differ.
Capacity and installation conditions make modest adjustments to the baseline. Additional work such as electrical upgrades, gas-line modifications, old-unit removal and permits is then displayed separately.
Average Water Heater Replacement Cost in 2026
A standard tank water heater typically costs about $600 to $3,100 installed. Tankless systems generally cost about $1,400 to $5,600 installed.
The final cost depends on heater type, capacity, fuel source and whether the project requires plumbing, gas or electrical modifications.
Water Heater Cost by Type
| Water heater type | Typical installed cost |
|---|---|
| Standard tank | $600–$3,100 |
| Tankless | $1,400–$5,600 |
| Hybrid heat pump | $2,000–$4,600 |
| Indirect | $2,000–$4,500 |
| Solar | $3,000–$9,000 |
Standard Tank Water Heater Replacement Cost
Traditional tank-style water heaters are generally among the least expensive systems to replace. A standard tank replacement costs about $600 to $3,100 installed.
The tank itself can cost approximately $400 to $2,100 for a common 40- to 50-gallon unit before installation.
Water Heater Cost by Tank Size
| Tank size | Typical installed cost |
|---|---|
| 30 gallons | $500–$1,900 |
| 40 gallons | $600–$3,000 |
| 50 gallons | $700–$3,100 |
| 65 gallons | $900–$3,400 |
| 75 gallons | $1,100–$3,600 |
| 80 gallons | $1,200–$4,000 |
Tankless Water Heater Replacement Cost
Tankless water heaters typically cost about $1,400 to $5,600 installed. Gas tankless systems can cost more when the project requires new venting, a larger gas line or other modifications.
Replacing an existing tankless unit with another compatible model is usually less complicated than converting a conventional tank system to tankless.
Heat Pump Water Heater Cost
A hybrid heat pump water heater typically costs approximately $2,000 to $4,600 installed. These systems require adequate space and airflow because they extract heat from the surrounding air.
Installation may also require electrical work and a condensate drain.
Gas vs. Electric Water Heater Cost
Angi reports broad installed ranges of approximately $600 to $3,500 for electric water heaters and $700 to $2,700 for gas systems. The exact price depends on system type, capacity and existing utility connections.
Changing from one fuel source to another can cost more because the project may require new wiring, gas piping, venting or other infrastructure.
How Much Does Water Heater Installation Labor Cost?
Labor to replace a traditional tank water heater commonly costs about $200 to $1,000. Tankless installation labor can range from approximately $800 to $3,000 because these systems may require more complicated plumbing, electrical or gas work.
The calculator does not add standard labor separately because its base ranges already represent installed prices.
Water Heater Permit Cost
Permit requirements depend on local building codes and the type of work performed. Angi reports water heater replacement permit costs of approximately $25 to $300.
Projects involving gas, plumbing or electrical changes may also require inspections.
What Can Increase Water Heater Replacement Cost?
Changing system type
A direct replacement is usually simpler than converting from a tank heater to tankless or changing fuel sources. Conversions can require new plumbing, wiring, gas lines or venting.
Electrical upgrades
Some electric tankless and heat pump systems require electrical capacity that the existing circuit cannot provide. An electrician may need to install new wiring, breakers or other equipment.
Gas and venting modifications
Gas-fired equipment requires properly sized fuel lines and safe venting. Tankless conversions can be particularly sensitive to these requirements.
Difficult access
Installation can take longer when a water heater is located in a tight closet, attic, crawl space or another difficult-to-access location.
Water Heater Repair vs. Replacement
Repair may make sense when the heater is relatively young and the problem involves a replaceable component. Replacement becomes more likely as an older tank approaches the end of its service life or develops significant corrosion or leakage.
Angi reports that tank-style water heaters commonly last about 6 to 12 years, though maintenance, water quality and equipment design affect actual lifespan.
What Is Included in This Estimate?
The calculator’s baseline represents the water heater and typical professional installation. It is intended to approximate a straightforward residential replacement using the selected system type.
Additional removal, permits and utility modifications are displayed separately to make the estimate easier to compare with contractor proposals.
What Is Not Automatically Included?
Major plumbing relocation, structural work, extensive electrical-panel replacement, major gas-service upgrades, water-damage repairs and unusual code corrections are not automatically included.
Rebates and tax incentives are also excluded because eligibility and program availability can change.
Calculator Methodology
HomeFixLedger uses current U.S. installed water heater cost ranges as its baseline. A standard tank uses approximately $600 to $3,100, tankless $1,400 to $5,600, hybrid heat pump $2,000 to $4,600, indirect $2,000 to $4,500 and solar $3,000 to $9,000.
Because these are installed prices, the calculator does not add a separate standard labor charge. Capacity, project type and access provide moderated adjustments to the baseline rather than adding another complete installation price.
Old-unit removal, permits and significant electrical or gas modifications remain separate. This reduces the risk of counting standard installation work twice.
The estimate is intended for budgeting residential projects and does not determine the correct water heater size or fuel system for a specific home.

How much does it cost to replace a water heater in 2026?
Angi reports an average water heater replacement cost of about $1,347 in 2026, while the total varies considerably according to the type of system and installation requirements.
How much does a 50-gallon water heater cost installed?
A 50-gallon tank water heater typically costs approximately $700 to $3,100 installed. Equipment quality, fuel source and installation conditions affect the final price.
How much does a tankless water heater cost installed?
A tankless water heater generally costs about $1,400 to $5,600 installed. Converting from a tank system may increase the cost if new utility connections or venting are required.
