Replacing a tank water heater costs $1,361 on average in Georgia, and Atlanta-area installations range from $800 to $2,000. The final price depends on the tank size, the fuel type and the installation location.

The Georgia average comes from HomeServe (September 2025), and the Atlanta range comes from Angi (accessed October 2026). Our water heater replacement service in Marietta covers the full installation process.
How Much Does a Water Heater Cost by Size and Fuel Type?
A 50-gallon water heater costs $1,300 to $1,800 installed for electric and $1,300 to $2,000 installed for gas in the Atlanta area. Larger tanks cost more. The table shows Atlanta prices from HomeBlue (January 2022).
| Tank size | Electric, installed | Gas, installed |
|---|---|---|
| 30 gallons | $1,000 to $1,300 | $1,100 to $1,400 |
| 40 gallons | $1,100 to $1,400 | $1,100 to $1,500 |
| 50 gallons | $1,300 to $1,800 | $1,300 to $2,000 |
| 60 gallons | $1,500 to $2,100 | $1,500 to $2,300 |
| 75 gallons | $1,700 to $2,300 | $2,000 to $2,500 |
| 80 gallons | $2,000 to $2,600 | $2,100 to $2,700 |
These 2022 figures set a baseline. Equipment and labor prices change each year, so a current written quote gives the exact price.
Does a Gas Water Heater Cost More Than Electric?
Yes. A gas water heater costs slightly more to install than an electric model of the same size. A gas model needs a gas connection and a vent, which add labor. Switching from electric to gas adds a new gas line and venting, which raises the price further.
What Does a Water Heater Replacement Price Include?
A water heater replacement price includes 6 parts: the new unit, removal of the old tank, labor, connection parts, safety parts and the permit.
- New water heater. The tank, sized to the household’s hot water use.
- Old tank removal. Draining, disconnecting and hauling the old unit away.
- Labor. A licensed plumber sets, connects and tests the new heater.
- Connection parts. Water lines, fittings, and gas or electrical connections.
- Safety parts. A temperature and pressure (T&P) relief valve discharge line, and an expansion tank where the system requires one.
- Permit. Cobb County or the City of Marietta issues the permit, depending on the address.
Ask the plumber which of these 6 parts the quote covers. A low quote that leaves out removal or the permit costs more in the end.
What Raises or Lowers the Cost of a New Water Heater?
Tank size, location, fuel switch and timing raise or lower the cost of a new water heater. HomeBlue lists these price factors for Atlanta installations:
| Raises the price | Lowers the price |
|---|---|
| Tanks larger than 60 gallons | Tanks of 50 gallons or less |
| Tight or hard-to-reach locations | Easy-to-reach locations |
| Upper-floor or basement installation | Main-level or garage installation |
| Switching fuel type, such as electric to gas | Same fuel type as the old heater |
| Emergency installation | Replacement scheduled in advance |
When Is Replacement Better Than Repair?
Replacement beats repair when the tank leaks, the tank is 10 years old or older, or the repair costs close to half the price of a new heater. The US Department of Energy places the life of a tank water heater at 10 to 15 years.
A water heater diagnosis costs $104 on average in Georgia, and a repair costs $404 on average, according to HomeServe (September 2025). A leaking tank cannot be repaired. Our guide Water Heater Repair or Replace walks through the full decision.
How Do You Lower the Cost of a Water Heater Replacement?
Lower the cost of a water heater replacement by scheduling the job before the old tank fails, keeping the same size and fuel type, and comparing written quotes.
- Plan ahead. A tank near 10 years old is due. Scheduled replacement avoids emergency rates.
- Keep the same size and fuel. A like-for-like swap needs the least labor.
- Check rebates. Utility rebates for ENERGY STAR water heaters change each year. Ask your gas or power company.
- Compare written quotes. Confirm each quote includes removal, parts and the permit.
