Water Heater Replacement Cost (2026) — Typical US Range

Replacing a common 40- or 50-gallon tank water heater in a US single-family house — gas or standard electric, in the same closet, basement, or garage, on the same fuel, with the old tank hauled away — often clusters around $1,400–$2,800. The wider national spread, about $1,100–$8,500, covers a basic electric swap on an easy slab at the low end and a tankless unit, a heat-pump water heater, a move to another room, or a tight install at the high end. A new electrical service, or a gas line run the length of the house, can clear that spread. This is a planning range, not a quote.

This page is a residential water heater. A boiler that also heats the house, a commercial rack of tanks, and a solar thermal system are different products. A heat-pump water heater, sometimes called a hybrid, heats water. It is not the ducted heat pump priced on the furnace guide or the central air guide.

The carton price is not the job. A tank at a home center can look like several hundred dollars. The bid is the permit, the pan, the expansion tank, the discharge pipe, the connectors, and the trip to haul the old tank out without flooding the floor. A 50-gallon tank is not a small step up from a 40 in labor. Price the heater and the room you have, not a shelf tag.

Use the typical band when you are swapping a tank for a tank in the same spot. Use the wider spread when someone is proposing a heat-pump model, a new vent, or a different room. Price a tankless unit on the tankless guide.

What the range includes

The typical band assumes an existing single-family house, one 40- or 50-gallon tank, gas or standard electric resistance, set where the old heater sits, on the same fuel. It includes the new heater, haul-away, reconnecting the water lines and either the gas connector or the electrical whip, a new temperature-and-pressure discharge pipe, and a permit where the city requires one. An expansion tank, a drain pan, and seismic strapping, where those are required, belong on the bid. If they are missing from a low price, they were omitted.

A basic electric tank on a garage slab the truck can reach, in a lower-cost area, sits toward the floor of the wider spread and the bottom of the typical band. A gas tank with a short, sound flue sits in the upper half of the typical band. A closet on a second floor, or a flue the inspector will not pass, leaves that band.

The floor of the national spread, near $1,100, is a basic 40-gallon electric tank, same location, easy access, in a lower-cost market. It is not a tankless unit that someone discounted. The top, toward $8,500, is where a hard gas tankless conversion with a larger gas line and a new vent, a heat-pump water heater that needs a condensate drain and a new circuit, a move to another room, and a tight closet or crawl space usually land together. Price that tankless case on the tankless guide. A panel upgrade for an electric tankless unit, or a gas line trenched the length of the house, can clear that top. Treat a number above it as a different scope and ask which driver caused it.

None of the bands include a kitchen remodel, a bathroom remodel, a new furnace, a roof replacement, a main sewer line, or a whole-house repipe. A tankless unit added while the kitchen walls are open is the tankless guide, and it often pulls in the panel guide as well. Weak hot water in a bath is not a reason to hide a heater inside the tile allowance. A tub converted to a shower in the same season is the tub to shower conversion guide. A shower that is already a shower is the shower remodel guide. Do not fold the heater into that shower price. Scale from hard water is the water softener guide. Do not fold the softener into the heater price. If the furnace and the water heater share a chimney, and the new furnace will no longer use that flue, the water heater’s vent is part of this job. If water stains start at the vent flashing, price that leak on the roof guide before you blame the tank.

As a cross-check, not a bid: a standard electric tank in the same spot is often discussed around $1,200–$2,200, and a gas tank in the same spot is often discussed around $1,500–$2,800. A heat-pump water heater is often discussed around $2,500–$5,500 before any utility or state rebate. A whole-house gas tankless unit on an adequate gas line is typically $2,500–$5,500 on the tankless guide. A straightforward vent is inside that band. A gas-line upsize is extra, on that page. Ask for a tank price and a tankless or heat-pump price as two proposals if you are deciding between them. The planning numbers are before rebates. A federal credit that used to apply to some heat-pump water heaters ended after 2025. Ask what your utility still pays, and do not subtract a credit the bid assumed is gone.

What moves the price

Driver	How it changes the bid
Fuel and type	A standard electric tank is the simpler swap. A gas tank adds the flue. Tankless gas is a gas-line and vent job. A heat-pump water heater needs space, a condensate drain, and often a different circuit.
Size	A 40- or 50-gallon tank is the typical band. A 75-gallon tank, or two tanks, is more equipment and sometimes a larger gas line.
Location and access	A garage slab or an open basement is the planning job. A second-floor closet, a crawl space, or a unit above a finished ceiling is labor, and a move to another room is a different project.
Venting	Reusing a sound flue keeps a gas swap in the typical band. A failed metal flue, a switch from an atmospheric draft to a power vent, or a water heater left alone in a chimney the furnace no longer uses changes the job.
Code items	Pans, expansion tanks, ball valves, seismic straps, and a proper discharge pipe are small parts with real labor. A price with no permit, in a city that requires one, is not comparable.
Water and the house	Very hard water shortens tank life. It can justify a different anode. It does not, by itself, force tankless. A recirculation loop is its own line.

If the heater sits in a tight closet, say so. Gas units need combustion air. A heat-pump water heater needs room air to pull heat from, often on the order of a large closet or a basement, not a sealed cabinet. A unit that cannot get that air is the wrong product, not a bargain.

Electric tankless equipment often needs a large 240-volt load the panel may not have. Price the heater on the tankless guide and that service on the electrical panel guide. Do not fold the panel into the heater bid, and do not fold the heater into the panel bid.

DIY or hire

A confident owner can sometimes replace an electric tank like for like, in the same spot, where the city allows an owner to do it and a permit is pulled if one is required. The risks are water on the ceiling below and a connection that overheats. If you are not sure the joints will hold, hire the tank swap. The equipment is the cheaper part of a leak.

Hire for gas. Combustion air, the connector, a sediment trap, and the vent are where a small mistake becomes carbon monoxide. Hire for tankless, for a heat-pump water heater, and for any job that changes the vent path, the gas pipe size, or the room the heater sits in. A heat-pump model also needs a condensate drain that actually reaches a drain, and a circuit sized for that unit.

Changing a temperature setting, testing the temperature-and-pressure valve on the schedule the manufacturer prints, and keeping the area around the tank clear are ordinary owner tasks. They are not a replacement.

Repair or replace

Replace when the tank is leaking from the vessel. That leak does not get repaired in a way that is worth trusting. Also replace when the tank is past about 8–12 years and the repair is more than a valve or a thermostat, or when rusty water and a loud popping sound show the tank is full of sediment and the warranty is gone. Do the replacement on your schedule. A tank that fails on a Sunday night is the same equipment plus an emergency fee and wet drywall.

Repair elements and thermostats on a younger electric tank, and replace a temperature-and-pressure valve or a shutoff that weeps, as long as the tank wall is dry. Flushing a tank that was never maintained helps a little. It does not restore a tank that has already started to fail. A new thermostat does not fix a vessel leak.

No hot water is not automatically a dead tank. A tripped breaker, a failed ignitor, or a gas valve that will not open can be a repair on a younger unit. If the furnace and the water heater share a flue, and only one of them is being replaced, ask who is resizing the vent that remains. A new tank on a flue that is now too large is still a venting problem.

How to use this number

Ask for a written price that names the gallon size or, for tankless, the gallons-per-minute rating, the fuel, whether the heater stays in the same spot, the vent plan, whether an expansion tank and a pan are included, who hauls away the old tank, and whether a permit is pulled. Compare a 40- or 50-gallon tank bid with the typical band. Compare a heat-pump water heater, a move, and a tight location with the wider spread. Compare a tankless unit with the tankless guide, and make the type an option so you can see the tank versus the vent and the gas line.

A very low bid on a gas tank is a reason to ask whether the pan, the expansion tank, and the permit are included, not a reason to celebrate. A tankless quote near a tank price usually means the gas line and the vent were assumed to be adequate. Confirm that in writing. A high bid should point at tankless or heat-pump equipment, a new vent, a relocation, access, or a panel. Two or three local bids on the same fuel and the same location are the number that matters.
