How Much Does It Cost to Replace a Water Heater? (2026)
Your water heater is the appliance you never think about until the morning it hands you a cold shower. Then the quotes start arriving and it's hard to know which one is honest. Here are the real numbers for 2026 — by type, by tank size, and the line items that move your price.
Typical range
$1,000–$2,000
Most homeowners pay around
$1,500
Standard 50-gallon tank, like-for-like replacement, U.S. national average.
Cost by water heater type
Standard tank (gas or electric)
The most common job — and the cheapest
$600–$3,100
Tankless (gas or electric)
Higher up front, 20+ year life
$1,400–$5,600
Hybrid heat pump
Most efficient; needs space and airflow
$2,000–$4,600
Indirect (runs off your boiler)
Only if you have a boiler
$2,000–$4,500
Solar
Usually paired with a backup unit
$3,000–$9,000
Cost by tank size
40 gallon
1–3 people
$600–$3,000
50 gallon
3–5 people — the most common size
$700–$3,100
75 gallon
5+ people or high demand
$1,100–$3,600
Going one size up is usually a modest add and worth it if your old unit kept running out of hot water. Switching types — tank to tankless, for instance — costs more than switching sizes, because it usually means new venting, gas line, or electrical work.
What moves your price
Labor
A standard tank swap runs $200–$1,000 in labor. A tankless conversion is more involved at $600–$2,500. Tight or awkward installs add more.
Venting
Changing fuel type or moving to tankless often requires new venting: $500–$1,500.
Code upgrades
An expansion tank is required by code in many areas ($100–$400), and permits run $75–$500+ depending on your city.
Relocation
Moving the unit — out of a closet, into the garage — adds $500–$2,500 in piping and venting.
Piping
New or rerouted water lines run roughly $12–$15 per linear foot.
Old unit disposal
Hauling the old tank away typically runs $75–$500. It should be a line item, not a surprise.
Common questions
Is there still a tax credit for a water heater in 2026?
Not a federal one. The Section 25C credit — up to $2,000 for a qualifying heat pump water heater — was terminated after December 31, 2025 by the One Big Beautiful Bill Act. The unit had to be installed and in service by that date. Some state and utility rebates are still available, so check locally before you buy.
How much does it cost to replace a water heater?
A standard tank replacement typically runs $1,000–$2,000 installed. Tankless and heat pump units cost more up front but last longer and use less energy.
How long does the job take?
A straightforward tank swap is usually a few hours. A tankless conversion or a relocation can take most of a day.
Tank or tankless — which is worth it?
Tankless costs more up front, lasts longer, and only heats water on demand. If you're staying long-term and use a lot of hot water it can pay off. For a fast, budget-friendly replacement, a standard tank is hard to beat.
Can I repair it instead of replacing it?
Sometimes. A bad heating element or thermostat is a cheap fix. But a leaking tank, or a unit past ten years old, is usually a replacement rather than a repair.
How do I know it's time to replace it?
Rusty or cloudy hot water, water pooling under the unit, rumbling or popping sounds, running out of hot water faster than it used to, or simply age — most tanks last 6–15 years.
Why is my quote higher than these ranges?
Usually venting, permits, code upgrades, or relocating the unit. Ask for an itemized quote so you can see exactly which of those apply to your house.
