A water heater rarely gets attention until it fails — usually at the worst time. Replacing one costs $900 to $3,500 installed in 2026, averaging around $1,500, with the type you choose driving most of the difference.
What you’re paying for
The unit is one piece; the rest is labor (30–50% of the bill), permits, and any venting, gas-line, or code upgrades your install triggers. A straightforward like-for-like tank swap sits at the low end. Switching fuel types or moving to tankless pushes you up.
Cost by type
The biggest decision is tank vs. tankless — and within each, fuel type. The table below shows typical installed pricing so you can match a unit to your household and budget.
Tank vs. tankless vs. heat pump
A standard tank is cheapest to install and fine for steady, predictable use. A tankless unit costs more (especially gas, which often needs venting and gas-line upgrades) but lasts ~20 years, never runs out, and saves space. A heat-pump (hybrid) electric tank costs more upfront but slashes operating cost — the best long-run value where there’s room and a rebate.
Don’t wait for the leak
Tanks usually fail by leaking, which can flood a utility room or finished space. If yours is past 10 years and showing rust, noise, or lukewarm water, replacing it on your schedule is far cheaper than an emergency call plus water damage.
How to save on a water heater
- Match the type to your use instead of automatically upsizing.
- Stay with your current fuel and location to avoid venting/gas upgrades.
- Consider a heat-pump model for the lowest running cost, and check utility rebates.
- Flush it annually to get full life from whatever you install.
| Item | Typical range | Notes |
|---|---|---|
| Water heater unit | $400 – $2,500 | Tank cheaper; tankless higher |
| Installation labor | $150 – $1,900 | 30–50% of the project |
| Permits | $25 – $300 | When a plumbing project needs a permit on Permit Notebook, our sister site |
| Gas line / venting upgrades | $300 – $1,500 | Common when switching to tankless |
| Expansion tank & fittings | $40 – $350 | – |
| Option | Typical range | Notes |
|---|---|---|
| Electric tank (40–50 gal) | $900 – $2,200 | – |
| Gas tank (40–50 gal) | $1,200 – $3,100 | – |
| Tankless — electric | $1,400 – $3,500 | – |
| Tankless — gas | $2,500 – $5,600 | Often needs venting/gas upgrades |
| Heat-pump (hybrid) tank | $2,000 – $4,500 | Lowest operating cost |
What affects the price
- Tank vs. tankless Tankless units cost more to buy and install but last longer and never run out of hot water.
- Fuel type Gas units cost more than electric upfront but are usually cheaper to run; heat-pump models cut electric use sharply.
- Capacity Larger tanks (50–80 gallons) and higher-flow tankless units cost more.
- Venting & gas line Switching to a gas tankless often requires a larger gas line and new venting — a major cost add.
- Code upgrades Expansion tanks, seismic strapping, and pan/drain requirements vary by jurisdiction.
Water heater replacement cost by state
Where you live can change the price as much as the options you pick. Labor is a big part of the bill, and construction workers are paid more in some states than others. A typical water heater replacement job costs about $1,100 to $4,100 in Hawaii (17% above the U.S. average). In Arkansas, it costs about $770 to $3,000 (15% below the U.S. average).

Common questions
- Is tankless worth the extra cost?
- Tankless units cost more upfront but last ~20 years (vs. 8–12 for a tank), never run out of hot water, and save space and standby energy. The payback is best for households with high or variable hot-water use.
- How long does a water heater last?
- Standard tanks last 8–12 years; tankless units last about 20 years. Annual flushing extends the life of both.
- Gas or electric — which is cheaper?
- Electric units are cheaper to install; gas units cost more upfront but are usually cheaper to operate where natural gas is available. A heat-pump (hybrid) electric model has the lowest running cost of all.
- Why is tankless installation more expensive?
- Beyond the pricier unit, a gas tankless often needs a larger gas line, new stainless venting, and electrical work — which is why installed costs reach $2,500–$5,600.
- Is a heat-pump water heater worth it?
- Heat-pump water heaters use 60–70% less electricity than standard electric tanks. They cost more upfront but pay back through lower bills, and some utilities still offer rebates.
- What are the signs I need a new water heater?
- Rusty or lukewarm water, popping or rumbling noises, pooling water around the base, and an age past 10 years all point to replacement.
- Can I install a water heater myself?
- A like-for-like electric tank swap is possible for skilled DIYers, but gas, venting, and permits make professional installation the safer choice — and a bad install can void the warranty or fail inspection.
