Water heater replacement cost by type
These are installed prices, meaning the unit plus labor. Each guide uses its own data, so the ranges do not match exactly. Use them to judge whether a quote is in a normal range, not as a fixed price.

What drives the price
A same-for-same swap is the cheapest job. A 50 gallon gas tank replaced with another 50 gallon gas tank in the same spot needs little extra work. Costs climb when anything changes.
Fuel type and conversions
HomeGuide puts a switch from electric to gas at $400 to $2,000 or more, depending on whether a gas line is already there. Going from gas to electric runs $250 to $1,000 or more for a new circuit and wiring.
Venting
Gas units must vent safely. HomeGuide lists $100 to $600 to replace existing vents and $500 to $1,500 for first-time venting. This Old House puts power venting at $300 to $600, plus $300 to $500 for electrical work.
Gas line and electrical upgrades
HomeGuide puts a larger gas supply line at $350 to $2,000. A new dedicated electrical circuit runs $250 to $900 in its data. Many electric tankless units need one.
Expansion tank, drain pan and code upgrades
Older installs often do not meet current code. A plumber may need to add an expansion tank, a drain pan or a proper relief valve line. HomeGuide lists an expansion tank at $100 to $400 and other code fixes at $75 to $500 or more. Angi puts an expansion tank at $90 to $350.
Haul-away, permit and after-hours work
- Old unit removal: $75 to $500 (HomeGuide). Many plumbers include it.
- Permit: Angi lists $25 to $300. HomeGuide lists $50 to $200 for gas or electrical permits.
- Emergency service: This Old House puts it at $200 to $500 extra.
- Tight spaces: HomeGuide adds $125 to $300 per labor hour for hard-to-reach closets and attics.
Hard water
Minerals in hard water settle in the bottom of a tank and build scale in tankless units. That can shorten service life and cut efficiency. HomeGuide notes that tankless units need regular flushing and descaling for hard water deposits. Ask your water utility for your hardness level, and ask your plumber whether a softener or a flushing schedule makes sense.
Tank vs tankless vs heat pump
Tank: The lowest upfront cost and the simplest install. HomeGuide and Fixr both list a typical lifespan of 8 to 12 years.
Tankless: Hot water on demand and a smaller footprint. It costs more to install because of gas line, venting or electrical work. HomeGuide and Fixr list a lifespan of 15 to 20 years. Gas tankless units cost more upfront than electric ones but deliver higher flow, per HomeGuide.
Heat pump (hybrid): An electric tank that pulls heat from the surrounding air. ENERGY STAR estimates a family of four can save about $550 per year on electric bills compared with a standard electric water heater, and it assumes a 13-year lifespan. Ask a plumber whether your space has the room and airflow it needs.
Permits and licensing in Texas
In Texas, plumbing work for hire must be done by a person licensed by the Texas State Board of Plumbing Examiners (TSBPE). Plumbing companies work under a Responsible Master Plumber. A water heater swap counts. The one narrow exception: Texas Occupations Code 1301.051 lets a property owner do plumbing on their own homestead without a license. Local permit rules still apply.
Many Texas cities require a permit to replace a water heater. Rules and fees differ by city, so ask your city’s building or permits office before the job starts. A licensed plumber usually pulls the permit. An inspection helps confirm the venting, gas connection and relief valve are safe.
Before you hire anyone, look up the license. Our guide on how to check a plumber’s license in Texas walks you through it.

Repair or replace?
HomeGuide suggests replacing a water heater that is over 10 years old or when a repair would cost more than half the price of a new one. It lists tank repairs at $150 to $700 and tankless repairs at $300 to $1,300.
Signs it may be time to replace:
- Water pooling around the base or a leak from the tank itself
- Rusty or discolored hot water
- Rumbling or popping sounds from sediment
- Hot water running out faster than it used to
- The unit is past the typical 8 to 12 year range for tanks
A failed thermostat, heating element or igniter can often be repaired. A leaking tank cannot. You can find the age on the serial number label, or ask a plumber to read it.
How to get an accurate quote
Step 1: Gather the basics
Note the fuel (gas, propane or electric), tank size, location and age from the label. A photo of the unit and its venting helps a plumber price the job.
Step 2: Get two or three quotes for the same unit
Compare the same type and size. HomeGuide suggests at least three estimates.
Step 3: Ask what is included
Ask whether the price covers the permit, haul-away, expansion tank, drain pan, venting and any code upgrades.
Step 4: Check the license
Look up the plumber on the TSBPE site before you sign.
Step 5: Get it in writing
Ask for an itemized quote and the warranty terms for both the unit and the labor.
Red flags
- A price given over the phone with no questions about your venting, fuel or location
- No mention of a permit when your city requires one
- No license number, or a name that does not appear in the TSBPE lookup
- A demand for full payment before work starts
- Pressure to buy a much larger or pricier unit without a clear reason
- A quote that leaves out haul-away and code items, then adds them later
Frequently asked questions
How much does it cost to replace a water heater in Texas?

Can a handyman replace my water heater in Texas?
Plumbing work for hire in Texas must be done by a person licensed by the Texas State Board of Plumbing Examiners. A homeowner may do plumbing on their own homestead without a license, but local permit rules still apply.
How long does a water heater last?
