Water Heater Replacement Cost in Eau Claire: Tank vs Tankless Prices

Water Heater Replacement Cost in Eau Claire: The Short Answer

Water heater replacement cost runs $600 to $3,100 installed for a standard tank and $1,400 to $5,600 for a tankless unit, according to national figures from HomeGuide. HomeAdvisor’s national average is $1,348. No published price survey covers Eau Claire, so use these as national starting points and ask the plumbers in Eau Claire on our directory for itemized written quotes.

Like-for-like swaps cost the least. HomeGuide says replacing a tank with a similar tank is typically cheaper than a retrofit that needs plumbing or electrical changes, and HomeAdvisor estimates labor at about 50% of the total. Inside the City of Eau Claire, the 2026 fee schedule adds a $50 plumbing fee for a water heater replacement.

Water Heater Replacement Cost by Type: Tank, Tankless, Heat Pump

HomeGuide’s national prices, before tax incentives or rebates:

Type	Unit only (HomeGuide, national)	Installed (HomeGuide, national)
Standard tank (40 to 50 gallon)	$400 to $2,100	$600 to $3,100
Tankless	$600 to $2,600	$1,400 to $5,600
Hybrid heat pump	$1,500 to $3,000	$2,000 to $4,600
Indirect	$1,500 to $3,000	$2,000 to $4,500
Solar	$1,000 to $6,000	$3,000 to $9,000

HomeAdvisor’s national installed ranges are narrower: $600 to $2,500 for a tank, $1,400 to $3,900 for tankless, and $1,200 to $3,500 for a hybrid heat pump.

How much does a tank water heater cost by size?

Bigger tanks cost more, with HomeGuide’s national installed price rising from $500 to $1,900 for 30 gallons to $1,200 to $4,000 for 80 gallons.

Tank size	Installed (HomeGuide, national)
30 gallon	$500 to $1,900
40 gallon	$600 to $3,000
50 gallon	$700 to $3,100
65 gallon	$900 to $3,400
75 gallon	$1,100 to $3,600
80 gallon	$1,200 to $4,000

HomeGuide suggests 40 gallons for 1 to 2 people with low usage and 50 gallons for 3 to 4 people with moderate usage.

How much does a tankless water heater cost?

HomeGuide’s national installed range is $1,400 to $5,600, and HomeAdvisor’s national average is $2,641. By fuel, HomeGuide lists electric at $1,400 to $3,000 installed, propane at $1,600 to $4,500, and natural gas at $2,100 to $5,600. If you are choosing between fuels, our propane vs natural gas guide covers the tradeoffs.

Switching from a tank adds labor. HomeGuide puts a tank-to-tankless upgrade at $600 to $2,500 in labor and half to a full day of work, while replacing tankless with tankless keeps labor at the lower end.

Operating costs narrow the gap. HomeGuide’s national annual estimates are $220 to $480 for gas tankless and $340 to $540 for electric tankless, against $250 to $420 for a gas tank and $530 to $600 for an electric tank. Focus on Energy says natural gas tankless units save 25% to 50% in water heating costs over a standard tank.

Water Heater Replacement Cost Add-Ons: Venting, Gas Lines, Permits

HomeGuide’s national add-on prices:

• Venting: $500 to $1,500 if the home has never had it, or $100 to $600 to replace existing vents. Power vent models cost $350 to $500 more than direct vent (HomeAdvisor says power venting adds $600 to $1,100).
• Larger gas supply line: $350 to $2,000.
• Dedicated electrical circuit: $250 to $900, and $850 to $1,700 if the panel must be replaced. That part of the job may need electricians in Eau Claire.
• Expansion tank: $100 to $400.
• Code compliance updates: $75 to $500 or more.
• Moving the water heater: $500 to $2,500.
• Difficult installs: $125 to $300 per labor hour, plus extra charges for emergency or after-hours work.

Do you need a permit to replace a water heater in Eau Claire?

Yes, and the City of Eau Claire’s 2026 fee schedule sets the plumbing fee for a water heater replacement at $50. The same schedule doubles applicable fees if plumbing work starts before the permit is obtained. The city’s plumbing inspections brochure says the permit must be obtained by a licensed master plumber or by the owner who resides in the home before any fixture is added or removed.

Wisconsin law treats this as plumbing work. Statute 145.01 defines plumbing to include water heaters and their installation, and 145.06 requires a licensed master plumber to be in charge of every installation. The exception is a property owner working in a one-family building they own and occupy as a home, unless a local ordinance requires a license.

Water Heater Replacement Cost and Eau Claire Winters

Is a tankless water heater worth it in a cold climate?

It can be, as long as it is sized for colder incoming water, which takes more capacity. An ENERGY STAR technical bulletin says a tankless unit’s output depends partly on groundwater temperature, so colder climates generally need higher-capacity units, and it recommends an experienced plumber for sizing.

Sizing comes down to flow and temperature rise. HomeGuide’s example: with 60 F ground water and a 115 F target, the unit must add 55 F, and a higher rise demands more capacity. ENERGY STAR lists typical flows of 2.5 GPM for a shower, 3.3 GPM for a clothes washer, 2.2 GPM for a sink, and 1.3 GPM for a dishwasher. HomeGuide suggests at least 3.5 GPM for 1 to 2 fixtures at once, 5 GPM for 2 to 3, and 7 GPM or higher for 3 to 4.

Fuel and venting matter here. HomeGuide says gas tankless units perform better in cold climates, while electric models have limited cold weather performance. The Department of Energy’s Building Science Education program says cold climates require sealed-combustion, direct-vent, or power-vented equipment, with intake and exhaust vents placed sufficiently above the expected snow line and the intake kept apart from the exhaust to prevent frost buildup.

Can a heat pump water heater work in a Wisconsin basement?

It can, if the space stays between 40 and 90 F year-round and has 1,000 cubic feet of air around it, according to ENERGY STAR. It names a furnace room as a good spot and notes the unit can cool the space it sits in. In colder months, with colder incoming water, a heat pump model may temporarily switch to backup standard electric mode and use more energy, though ENERGY STAR says hybrid models keep making hot water below 40 F. If the basement or garage gets close to freezing, our guide on how to keep pipes from freezing applies to the water lines too.

ENERGY STAR estimates a certified heat pump model can save a household of four about $425 per year compared with a standard electric water heater. If the furnace is also near the end of its life, our furnace replacement cost guide can help you plan both, and HVAC contractors in Eau Claire handle that side.

Water Heater Replacement Cost After Rebates

Focus on Energy offers instant discounts through participating distributors, passed through your Trade Ally contractor and taken off the invoice, with no forms. The minimum discounts are $300 for a qualifying heat pump water heater, $200 for an indirect water heater paired with a boiler of 90% efficiency or higher, and $100 for a qualifying tankless unit. Ask the Trade Ally whether they work with a participating distributor and whether your model qualifies. Our Focus on Energy rebates guide covers the rest of the program.

Income-qualified households under 150% of area median income may also qualify for up to $1,750 toward an ENERGY STAR electric heat pump water heater through the HEAR program. As of September 1, 2026, Focus on Energy can no longer accept retail post-purchase or instant discount coupon requests for equipment replacing fossil fuel appliances, so a store purchase that replaces a gas water heater no longer qualifies through the retail path. HEAR still lists a registered contractor path for heat pump water heaters.

Is there a federal tax credit for a water heater in 2026?

No, the federal 25C credit does not apply to a water heater installed in 2026. The IRS says the Energy Efficient Home Improvement Credit is not allowed for property placed in service after December 31, 2025.

Water Heater Replacement Cost vs Repair: How Long a Water Heater Lasts

How long does a water heater last?

A tank water heater lasts 8 to 12 years and a tankless unit 15 to 20 years, according to HomeGuide. HomeGuide says regular maintenance can stretch a tank to 15 years: flushing every 6 to 12 months, replacing the anode rod every 3 to 6 years, and adding an expansion tank.

When should you replace a water heater instead of repairing it?

Consider replacing once it is more than 10 years old or when a repair would cost more than 50% of a new unit, per HomeGuide. National repairs run $150 to $700 for a tank and $300 to $1,300 for tankless. ENERGY STAR lists the warning signs: visible corrosion, leaks, rust in your water, running out of hot water, and rumbling noises from sediment. In some cases the manufacture date is printed on the tank label near the serial number. ENERGY STAR adds that waiting for a sudden failure risks a tank rupture and water damage, and an emergency replacement can cost more and limit you to less efficient models.

What happens to the old water heater?

Water heaters are banned from Wisconsin landfills, according to the DNR. HomeGuide puts removal and disposal at $75 to $500 nationally and says most plumbers include it in the replacement estimate. Eau Claire County residents can also drop one off free at First Choice Computer Recycling, under drop-off pricing sponsored by Eau Claire County Recycling. Our appliance repair vs replace guide covers other large appliances.

Water Heater Replacement Cost: Comparing Quotes

HomeGuide suggests at least 3 estimates for the same type and size of water heater, from licensed, insured, and bonded installers, with removal of the old unit and permits included. Get an itemized estimate, contract, and warranty in writing, and never pay in full before work starts. ENERGY STAR suggests asking whether the installer will pull the local permit and, for a gas tankless unit, how the combustion gases will be vented.
