How to pay for a water heater replacement.
If there is water on the floor right now, you are buying today, and you are choosing between whatever two options an installer can get on a truck. Here is the price, the money, and the decision you can make in an afternoon.
The number you are actually financing
Water heaters get replaced under pressure, which is exactly when people stop asking what the price is made of. It is worth five minutes.
A heat pump water heater runs $3,600 to $6,500 installed. The spread is not random. Replacing an existing electric tank lands at $3,600 to $4,800, because the 240V circuit the new unit needs is already there. Replacing a gas tank lands at $4,300 to $6,500, because a gas swap usually needs a new 240V circuit run from the panel, and that means an electrician on the job alongside the plumber. Angi reports an average installed price of $4,200 across all scenarios, with a range of $2,800 to $8,000.
The cheapest version of this job. The 240V circuit is already there, the unit goes back in the same spot, and the room has the space, the headroom, and the drain the new unit needs.
A gas swap usually needs a new 240V circuit run from the panel, and the old gas line and vent have to be capped and closed off properly. That electrical work is most of the difference between this band and the one above.
Angi's average installed price, with a reported range of $2,800 to $8,000. Averages hide the drivers, so read the two bands above before you decide which end of that spread your house sits at.
Within those bands, five or six specifics do almost all the work:
What pushes you to the low end
- You are replacing an electric resistance tank, so the 240V circuit already exists.
- The new unit goes in the same location as the old one, with no re-piping.
- The space is big enough and open enough for the heat pump to pull air from, with the headroom the taller cabinet needs.
- There is a usable floor drain or an existing condensate route nearby.
What pushes you to the high end
- A gas-to-electric conversion, which usually means a new dedicated 240V circuit run from the panel.
- No gravity drain, so the job needs a condensate pump.
- A closet or other confined space, which needs ducting to bring in and exhaust air.
- An 80-gallon unit instead of a 50 or 65, for a bigger household or a longer recovery window.
- A high-labor metro market, where the plumbing and electrical hours cost more than the equipment.
One thing we will not publish: a national installed price for a conventional gas or electric-resistance tank. Our cost research does not carry a verified figure for either, and a made-up comparison number is worse than none. The comparison you want is not a national average anyway. Ask your installer for the delivered, installed, all-in price of both options on your job, quoted the same day, in writing. That number reflects your electrical panel, your space, and your local labor rates, which is the only version of the question that matters when you are the one paying.
For the full cost breakdown by scenario, read the heat pump water heater cost guide. To see what the operating-cost difference is worth over the life of the unit, run the heat pump water heater savings calculator with your own electric rate. If the gas-conversion route puts you in front of an electrician anyway, the electrical panel upgrade cost guide covers what a panel-only swap versus a full service upgrade runs, in case your panel is the real constraint.
The cheapest measure to electrify well
Water heating is the one appliance where the efficient version is close enough in price that the subsidy math usually closes the gap.
Of everything in a house you could electrify, a water heater is the smallest, cheapest, and least disruptive to get right. A heating system replacement is a five-figure decision that changes how the whole house feels. A water heater is a box in the basement with two pipes and a circuit. That makes it the easiest place to spend money well, and it is why state and utility programs subsidize heat pump water heaters more readily than almost anything else on the list except insulation.
The federal design reflects that too. The Home Electrification and Appliance Rebates program carries a per-measure cap of $1,750 for a heat pump water heater, where the state program is live and your household income qualifies. On a $4,200 job, that is a meaningful share of the price. It is a design cap, not a guarantee: a federal allocation to a state is not a rebate you can claim, and section 04 covers what changed about who qualifies.
Now the honest part. A heat pump water heater is not a drop-in replacement, and there are basements where it is the wrong answer:
- Space. The unit is taller than the tank it replaces and needs air volume around it to pull heat from. A tight utility closet works only with ducting, which adds cost and complexity.
- Noise. There is a compressor and a fan. In an unfinished basement, nobody notices. On the other side of a bedroom wall, people do.
- Drain. The unit makes condensate. A nearby floor drain solves it for nothing. No drain means a condensate pump, which is another component that eventually fails.
- Cold air out. It takes heat out of the room it sits in and puts it in the water. In a basement you were not heating, that is free. In a conditioned space, you are paying your heating system to make heat the water heater then steals back.
None of that is disqualifying for most houses, and all of it is worth checking before an installer arrives with a unit on the truck. The full case, including where the answer is genuinely no, is in are heat pump water heaters worth it.
Cheapest money first
Work down this list in order. Every dollar you take from a higher line is a dollar you do not borrow at a worse rate on a lower one.
Rebates you do not pay back
What it is State, utility, and (where a program has actually launched and you qualify) federally funded rebates on a heat pump water heater. Some come off the price at the point of sale, some arrive as a check after the work passes inspection.
What it costs you Nothing. No interest, no fees, no payments. This is the only line on the list like that.
Who it fits Everyone, and always first. A rebate applied before you finance shrinks the amount you borrow, which cuts the interest on every month that follows. The catch on an emergency replacement is time: most rebate programs require a participating or registered installer and a specific qualifying model, and neither is something you can arrange at 7pm on a Sunday.
0% and low-interest state and utility loans
What it is Loan programs run by state efficiency agencies, green banks, and utilities, subsidized to sit well below a bank rate. Terms and eligible measures vary a lot by state.
What it costs you Anywhere from 0% to single-digit APRs, sometimes with an origination fee on the shortest terms. Tacoma Power, for example, finances a heat pump water heater at 0% on a 5-year term up to $5,000, with pre-approval required (verified July 11, 2026).
Who it fits Anyone whose state or utility runs one, and whose replacement can wait long enough to get approved. Check the eligible-measure list before you assume a water heater counts: Efficiency Maine's Home Energy Loans cover heat pumps, insulation, and air sealing, which is not the same list as every appliance in the basement (verified July 15, 2026).
Utility on-bill financing
What it is The utility pays the installer, and you repay the cost as a line item on your monthly bill instead of through a separate lender. Tacoma Power's water heater loan is this model.
What it costs you Usually 0% or close to it, with pre-approval and a participating contractor as the price of admission.
Who it fits Customers of a utility that offers it. The repayment mechanics are simple, and there is no new account to manage. The trade is control: you use the utility's contractor list and the utility's approved equipment, on the utility's timeline.
Home equity: a HELOC or a home equity loan
What it is Borrowing against the equity in your house, either as a revolving line you draw from or as a fixed lump sum on a fixed term.
What it costs you Rates well below unsecured borrowing, because the loan is secured by your home. Closing costs and an appraisal may apply, and both are hard to justify on a single $4,000 water heater.
Who it fits Households doing the water heater as part of a larger project (insulation, a heat pump, a panel upgrade) where the total is big enough to earn the setup cost. The revolving-versus-lump-sum decision is in our guide to a HELOC versus a home equity loan for energy upgrades.
Contractor or dealer financing
What it is Financing arranged inside the sales conversation, usually through a third-party lender the plumbing company works with.
What it costs you Wide. Promotional periods and deferred-interest structures can look like 0% and then reprice sharply if the balance is not cleared inside the promo window. The monthly payment is what gets quoted; the total cost of credit is what matters.
Who it fits Emergency replacements where speed beats rate, and buyers who read the terms. Ask for the APR, the total of payments, and what happens on the day the promotional period ends. Get those three numbers in writing before you sign.
Personal loan or credit card
What it is Unsecured borrowing that does not touch your house and does not require a contractor to participate in anything.
What it costs you The most expensive money on this list, priced almost entirely off your credit score. A card carried past the statement date is the worst version of it.
Who it fits A tank that failed this morning and a household that has no other option today. This is a legitimate answer to an emergency, not a plan. If you use it, refinance it into cheaper money once the water is hot again and you have time to apply.
A note on names. State and utility programs get named here with their terms and the date we verified them. Private financing gets described by category only, because rates move weekly and a lender name is not advice.
Two cautions on lines 02 and 03. First, eligible-measure lists are narrower than the program names suggest. A state loan built around heat pumps, insulation, and air sealing may or may not treat a water heater as a covered measure, and Efficiency Maine's list is exactly that shape (verified July 15, 2026). Read the measure list before you plan around the rate. Second, most of these programs require pre-approval before the work starts. Tacoma Power's 0% five-year water heater loan up to $5,000 requires it (verified July 11, 2026), and so does almost every 0% offer in the country. Approval after the fact is generally not a thing.
The full list of programs with verified terms is in state energy efficiency loans. The home equity decision, which only makes sense if the water heater is part of a larger project, is in HELOC vs. home equity loan for energy upgrades. And if a contractor puts a payment plan in front of you tonight, read HVAC financing explained first, because deferred interest is the part that gets people. Whole-project funding, across insulation, heating, and water heating together, is in how to pay for home energy upgrades.
What the federal money does and does not cover now
Most water heater rebate advice online was written before mid-2026. If a page promises you a federal tax credit, it is out of date.
25C is gone for 2026 installs
The Energy Efficient Home Improvement Credit was terminated for property placed in service after December 31, 2025, under the One Big Beautiful Bill Act (Public Law 119-21). Historically it was worth up to $2,000 a year on a qualifying heat pump water heater. That is past tense now.
Placed in service, not purchased
The IRS uses the date the equipment was installed and operational, not the date you bought it or signed the contract. A unit bought in 2025 and installed in 2026 does not qualify. A 2025 install is still claimed on the 2025 return filed in 2026, on IRS Form 5695.
HEAR still lists $1,750 for a water heater
The federal Home Electrification and Appliance Rebates design carries a per-measure cap of $1,750 for a heat pump water heater, income-tiered and capped at $14,000 per household overall. That is the design, not a promise your state is paying it.
Fuel switching no longer qualifies
Under DOE Program Notice 26-2 (dated May 29, 2026, verified July 15, 2026), HEAR rebates are no longer available for replacing a gas, oil, or propane appliance with an electric one. Replacing an existing electric tank can still qualify. Replacing a gas water heater generally cannot.
Insulation and air sealing come first
The same notice makes insulation and air sealing upgrades a prerequisite before appliance rebates. If your envelope work is not done, that is now a gate on the appliance money, not just good practice.
States are still amending
States paying under the old rules have roughly until the end of August or early September 2026 to amend their programs. Anything you read about your state's HEAR rules that predates June 2026 should be re-checked with the administrator.
Put those together and the practical rule for a water heater in 2026 is short. If you are replacing an electric resistance tank, the federal rebate path is still open in states where the program has launched and your income qualifies, up to the $1,750 heat pump water heater cap. If you are replacing a gas tank, assume the federal rebate is not there for you and go looking at state and utility programs instead, which run on their own rules and are frequently more generous than people expect. Either way, the envelope work now sits in front of the appliance money, so if your attic is under-insulated that is the first call, not the second.
The detail on the expired credit is in the heat pump tax credit expired. Which federally funded programs actually launched, and where, is in home energy rebates in 2026. Funding the insulation and air sealing that now comes first is in how to pay for insulation. And the programs specific to where you live are on your state page.

Run the Rebate MatcherTriage, in order
Five steps you can work through in an afternoon, in the order that keeps your options open longest.
Stop the water, then decide
Shut the cold-water supply valve at the top of the tank and kill power or gas to it. That converts an emergency into a decision you can make over an afternoon rather than in the first ten minutes. A failed tank is not a fire; it is a puddle and a cold shower.
Answer the 240V question first
Look at what feeds the current tank. If it is an electric tank on a 240V circuit, a heat pump water heater is a same-day-possible swap for many installers and sits in the $3,600 to $4,800 band. If it is gas, the heat pump route needs a new 240V circuit run from the panel, which means an electrician, possibly a permit, and the $4,300 to $6,500 band. That one question sets both your price and your timeline.
Check the space in five minutes
A heat pump water heater is taller than the tank it replaces, needs room to pull air from, blows cold air out into the space it sits in, and produces condensate that has to go somewhere. Measure the headroom, look for a floor drain, and note whether the unit would be in a finished room where the noise and cold exhaust would bother someone. If the answer is a tight closet, budget for ducting.
Ask for both delivered prices, not a model number
Our cost research does not carry a verified installed price for a conventional gas or electric-resistance tank, so we will not publish one. The comparison that matters is not a national average anyway: ask your installer for the delivered, installed, all-in price of the heat pump model and the conventional model on your job, same day, in writing. That is the only version of the comparison that reflects your electrical situation, your space, and your local labor rates.
Know when the emergency swap is the right call
If you have a household that needs hot water tonight, no 240V circuit, and no installer who can pull a permit this week, a like-for-like replacement is a defensible decision. It forfeits the rebate and locks in the operating cost of the old technology for the next decade or so, and it is still better than a week without hot water or a panic purchase at a bad price. Make it knowingly, not by default.
The timing trap worth naming plainly: nearly every rebate and every 0% loan requires pre-approval, a qualifying model, and often a participating installer. An emergency replacement done in eight hours will usually satisfy none of those. That is the real cost of waiting until the tank fails, and it is a good argument for replacing an aging water heater on your own schedule rather than on the tank's.
If the tank is still working and you are reading this in advance, you are in the best position anyone gets. Line up the rebate and the loan first, pick the installer without pressure, and let the replacement happen on a Tuesday you chose.
Water heater replacement questions
How much does a heat pump water heater cost?
Installed, $3,600 to $6,500. Replacing an existing electric tank runs $3,600 to $4,800 because the 240V circuit is already in place. Replacing a gas tank runs $4,300 to $6,500, because a gas swap usually needs a new 240V circuit run from the panel. Angi reports an average of $4,200 with a range of $2,800 to $8,000. The cost drivers that move you within those bands are the electrical situation, whether the space needs ducting or a condensate pump, tank size, and local labor rates.
Is there a rebate for a heat pump water heater in 2026?
Often yes at the state or utility level, and it depends heavily on where you live and what you are replacing. The federal HEAR program design caps a heat pump water heater rebate at $1,750, but under DOE Program Notice 26-2 (May 29, 2026, verified July 15, 2026) fuel switching no longer qualifies, so replacing a gas tank with an electric heat pump model generally does not earn a HEAR rebate. Replacing an existing electric tank still can, where the state's program is live and your income qualifies. State and utility rebates run on their own rules and are frequently the better bet. Check your state page and run the Rebate Matcher.
Can I finance a water heater?
Yes, through several channels. In order from cheapest to most expensive: state and utility efficiency loans (Tacoma Power finances a heat pump water heater at 0% on a 5-year term up to $5,000 with pre-approval, verified July 11, 2026), utility on-bill financing, home equity borrowing, contractor or dealer financing, and finally a personal loan or credit card. Check the eligible-measure list before assuming a state program covers water heaters: Efficiency Maine's Home Energy Loans list heat pumps, insulation, and air sealing (verified July 15, 2026).
Is there still a federal tax credit for a water heater?
No. The 25C Energy Efficient Home Improvement Credit was terminated for property placed in service after December 31, 2025, under the One Big Beautiful Bill Act (Public Law 119-21). It was historically worth up to $2,000 a year on a qualifying heat pump water heater. A unit placed in service on or before December 31, 2025 can still be claimed on the 2025 return filed in 2026, using IRS Form 5695. A 2026 install does not qualify, even if you bought the equipment in 2025.
What do I do if my tank died today?
Shut the cold-water supply valve at the top of the tank and cut power or gas to it, which stops the damage and buys you an afternoon. Then check what feeds the tank: an existing 240V circuit makes a heat pump water heater a realistic same-week swap, while a gas tank means an electrician and a longer timeline. Ask two installers for the delivered installed price of both the heat pump and the conventional option. If nobody can do the qualifying job this week and the household needs hot water now, a like-for-like emergency swap is a reasonable call even though it forfeits the rebate.
