Nashville's price band
Nashville is pricier than 95% of the 195 US metros we price for water heater work.
Expect $910–$2,850 for an electric tank swap, $1,250–$3,550 for gas, $1,350–$4,450 for a 75–80 gal tank and $2,200–$6,150 to switch to whole-home tankless gas. A repair, if the tank is sound, is $170–$795.
Nashville is a high-cost metro for plumbing work. Tanks cost about the same at every store in the country; what changes here is the plumber's hourly rate, the permit and how hard the old tank is to get out.
Prices on this page include the tank, a licensed plumber, standard water and gas or power connections and hauling the old tank away unless the row says otherwise. Most areas require a permit for a water heater swap; in Nashville budget $55–$320 for it.

Real-World Water Heater Costs in Nashville
Here's what common water heater jobs cost in Nashville in 2026, installed, with standard connections and haul-away.
Electric 50-gal tank, same spot — 2–3 hours
Drain, disconnect, carry out, set the new tank, new connectors, test. With the haul-away included, most Nashville plumbers land here. Add $110–$445 if the inspector wants an expansion tank.
Gas 40–50 gal tank with code fixes — 3–4 hours
The tank plus a new vent connector, gas flex line, drain pan and expansion tank. A plain gas swap starts at $1,250; each code fix adds a line to the quote. A power-vent conversion is another $335–$1,650.
Gas tank to whole-home tankless — half to full day
New wall-hung unit, new venting through the wall or roof and often a bigger gas line. Expect a yearly descale at $115–$400, more if the water is hard.
Electric tank to heat pump water heater — 2–8 hours
Same 240V circuit, plus a condensate drain. After a typical utility rebate the net is about $2,900. Switching from gas usually needs a new circuit and runs $2,500–$8,200.
Leaking tank, replaced the same day
After-hours and same-day calls bill at a premium. Shut the cold-water valve at the top of the tank and turn off the gas or breaker, then compare two quotes if you can wait until morning.
How much does water heater replacement cost in Nashville?
Between $900 and $3,550 for a 40–50 gal tank, installed, and $2,050 is the price most Nashville homeowners pay. The tank itself is $455–$2,050 at a store; the rest is labor, fittings, the permit and haul-away. Gas tanks cost more than electric because of venting and the gas connection.
Waiting for a leak costs money: a same-day emergency swap runs $1,150–$4,100 against $900–$3,550 booked ahead. Re-checked against 36 sources in November 2026.
Water heater prices in Nashville (2026): tank, tankless and heat pump

|---|---|---|---|
| Electric tank, 40–50 gal | $910 | $1,700 | $2,850 |
| Gas tank, 40–50 gal | $1,250 | $2,300 | $3,550 |

Gas vs electric in Nashville: a gas tank costs about $600 more to install than an electric one, but runs for about $275 a year against $645 at the US average rates. If you have gas, stay on gas unless you're going heat pump.
What moves a water heater quote in Nashville:
- Fuel — gas tanks need venting and a gas connection; electric tanks are the quicker swap ($1,700 vs $2,300 typical).
- Size — moving from 50 to 75–80 gal adds about $600 to the typical bill.
- Access — attic, crawlspace and tight-closet tanks take longer than garage tanks.
- Code fixes — expansion tank $110–$445, venting $335–$1,650, seismic straps where required.
- Timing — a same-day emergency swap costs $400 more than a booked one at the typical price.
Ask every Nashville plumber for the same five things: tank brand and size, what's included (haul-away, permit, connectors), any code fixes, the warranty on parts and labor, and the start date. Compare those, not the headline price. Get a quote for your water heater job →
Water Heater Cost in Nashville by Household Size
One or two people: a 40-gal tank at $910–$2,300. Three or four: a 50-gal tank at $900–$3,550. Five or more: a 75–80 gal tank at $1,350–$4,450 or tankless gas at $2,200–$6,150.
Worked example: a family of four in Nashville replacing a 50-gal gas tank pays about $2,300 installed and about $275 a year in gas at the US average rate. Over 10 years that's about $5,050. The same family on an electric tank pays about $1,700 up front and $645 a year — about $8,150 over 10 years.
A heat pump water heater at $2,900 after a typical rebate runs about $215 a year — about $5,050 over 10 years, far below the electric tank and close to gas, so it pays best in an all-electric home.
Nashville Water Heater Costs by Type
| Water heater type | Cost | Best for |
|---|---|---|
| Electric tank (40–50 gal) | $910–$2,850 installed | Homes without gas. About $645 a year to run at the US average rate; lasts 8–12 years. |
| Gas tank (40–50 gal) | $1,250–$3,550 installed | Homes with a gas line. About $275 a year to run; lasts 8–12 years. |
| Large tank (75–80 gal) | $1,350–$4,450 installed | Five or more people or a big tub. A big household on gas spends about $425 a year; lasts 8–12 years. |
| Whole-home tankless gas | $2,200–$6,150 installed | Endless hot water in less space. About $185 a year to run; often lasts 20 years or more with yearly descaling. |
| Whole-home tankless electric | $1,100–$4,950 installed | Small homes with spare electric capacity. About $605 a year; needs heavy circuits; often lasts 20 years or more. |
| Heat pump water heater (50 gal), switching from gas | $2,500–$8,200 installed | Gas homes going electric: usually adds a new 240V circuit. About $215 a year to run. |
| Heat pump water heater (50 gal) | $2,150–$5,950 installed | Electric homes with a garage or basement. About $215 a year to run; stores water in a tank, so it needs the same anode and flush care. |
| Solar with backup tank | $2,700–$9,750 installed | Sunny areas. Backup heat about $255 a year; the storage tank lasts about as long as a standard tank. |
| Point-of-use electric (one sink) | $445–$1,650 installed | A far bathroom or kitchen sink that waits too long for hot water. Pennies a day to run; tankless units often last 20 years or more. |
Tank price vs installed price — the Nashville water heater bill
A 50-gal tank costs $455–$2,050 at a big-box store, but the installed price in Nashville is $900–$3,550. The difference pays for a licensed plumber's two to four hours, new connectors and valves, the permit ($55–$320) and haul-away ($85–$450).
Buying your own tank rarely saves much. Many plumbers won't warranty a customer-supplied tank, and some charge more for labor-only. A quote for a tank they supply, at $2,050, usually includes a labor warranty you won't get otherwise.
What's included in a Nashville water heater quote (and what costs extra)
A standard installed price covers the new tank, a licensed plumber, draining and removing the old tank, new water connectors and a new gas flex line or electrical hookup, and a test run. The headline price often leaves out:
- Permit and inspection — $55–$320, required for a water heater swap in most of the US
- Expansion tank — $110–$445, often required when the home has a pressure regulator or check valve
- Venting or a power-vent conversion — $335–$1,650 on older or relocated gas installs
- Fuel switch — $340–$2,250 for a new 240V circuit if you go from gas to electric or heat pump
Ask whether haul-away of the old tank is included; most plumbers include it, some charge extra.
Gas or electric
An electric tank swap costs $910–$2,850 in Nashville; a gas tank $1,250–$3,550. Gas needs venting and a gas connection, both licensed work, and that is most of the gap.
Where the tank sits
A garage tank is the cheapest swap in Nashville. Basements with narrow stairs, crawlspaces and small closets add labor, and moving the tank to a new spot costs more again.
Code upgrades
The most common add-ons at a Nashville swap are an expansion tank ($110–$445) on homes with a check valve or pressure regulator, a drain pan where a leak would cause damage, and new venting on older gas installs.
Water hardness
Hard water shortens tank life everywhere it occurs. Ask your plumber about local water hardness; an anode rod ($170–$400) and a yearly flush keep a tank going 8–12 years.
Cold inlet water and tankless sizing
A tankless unit has to heat cold incoming water on demand, so size it for winter, not summer. Whole-home tankless gas runs $2,200–$6,150 installed in Nashville.
Is a heat pump a good fit here?
A heat pump water heater pulls heat from the room. The US Department of Energy says the space should stay between 40°F and 90°F with about 1,000 cubic feet of air; a Nashville basement or garage that stays above 40°F works, and the unit will cool the space a little.
Planned vs emergency
A booked swap costs $900–$3,550; a same-day emergency job $1,150–$4,100. Tanks give warning signs — rusty water, rumbling, a damp base — so replacing at 10–12 years saves the premium.
- Replace before it fails.A planned swap at $2,050 costs less than an emergency one at $2,450. If your tank is past 10 years, get quotes now.
- Stay with the same fuel and size.A like-for-like swap is the cheapest job in Nashville. Changing fuel adds $340–$2,250 for a new circuit, and gas lines or venting add more.
- Check for a utility rebate before you buy.Many utilities pay toward a heat pump water heater, some only through approved contractors or with a permit on file. The federal 25C tax credit ended for equipment placed in service after December 31, 2025, so check your utility and state instead.
- Ask for an itemized quote.Haul-away ($85–$450) and the permit ($55–$320) should be on the quote, not a surprise on the invoice.
- Repair if the tank is young.A failed element, thermostat or igniter on a tank under eight years old is a $170–$795 fix, not a new tank.
- Get two quotes.Prices for the same tank swap in Nashville spread from $900 to $3,550. Two written quotes is the easiest way to land near $2,050.
Nashville plumbers often quote by phone. Before you pay a deposit, get these in writing:
- Tank brand, model, size and fuel type
- What the price includes: removal and haul-away, new connectors, gas line or electrical hookup
- Permit and inspection, and who pulls the permit
- Any code fixes: expansion tank, drain pan, venting, seismic straps where required
- Tank warranty and the plumber's labor warranty
- Whether same-day or after-hours fees apply
- For tankless or heat pump: venting, gas line size, new circuits and condensate drain
- Start date, time on site and payment terms
How much does it cost to replace a water heater in Nashville?
$900–$3,550 for a 40–50 gal tank, installed, and $2,050 is typical. Electric tanks run $910–$2,850, gas tanks $1,250–$3,550.
How much is a tankless water heater in Nashville?
$2,200–$6,150 installed for whole-home tankless gas when replacing a tank, about $3,850 typical. The price includes new venting and often a bigger gas line.
What does a heat pump water heater cost in Nashville?
$2,150–$5,950 for a 50-gal model replacing an electric tank, or $2,500–$8,200 when switching from gas and adding a 240V circuit. After a typical utility rebate, about $2,900.
Is there still a federal tax credit for a new water heater?
No. The federal 25C credit for heat pump water heaters ended for equipment placed in service after December 31, 2025, and the 25D credit for solar water heaters ended for money spent after that date. Utility and state rebates still exist in many areas; check yours before you buy.
How much does water heater repair cost in Nashville?
$170–$795 to replace an element, thermostat, igniter or gas valve. An anode rod is $170–$400. If the tank itself is leaking, it has to be replaced.
Do I need a permit to replace a water heater in Nashville?
In most cases, yes. Water heaters involve gas or high-voltage power and pressure relief, so most US cities require a permit and inspection. Expect $55–$320; your plumber usually pulls it.
How much is an emergency water heater replacement in Nashville?
$1,150–$4,100 for a same-day swap of a 40–50 gal tank, against $900–$3,550 booked ahead. After-hours rates are the main difference.
Should I pick gas or electric in Nashville?
Stay with what you have unless you're switching to a heat pump. A gas tank costs about $2,300 installed and $275 a year to run; electric about $1,700 and $645 a year at US average rates.
How long does a water heater last?
A tank water heater lasts about 8–12 years, and a tankless unit often 20 years or more with yearly descaling. A heat pump model stores water in a tank, so it needs the same anode and flush care. Hard water shortens all of them.
What's included in a Nashville water heater quote?
The tank, a licensed plumber, removal of the old tank and new connections. Often extra: the permit ($55–$320), an expansion tank ($110–$445) and any venting or electrical work.
