What is a fair price to replace a water heater in New Jersey?
Published ranges, not a quote. Angi (updated July 20, 2026) puts a tank-style replacement at $882 to $1,826 nationally, $1,347 on average. HomeBlue's Newark page (dated January 13, 2022) lists $1,600 to $2,100 for a 40-gallon gas tank and $1,800 to $2,700 for a 50-gallon gas tank, while ExpectedCosts (undated) lists $800 to $1,500 for a 40 to 50 gallon tank in Elizabeth. Tankless runs $1,400 to $3,900 (Angi) or $1,400 to $5,600 (HomeGuide, January 2, 2026), and a heat pump water heater $2,000 to $4,600 installed (HomeGuide). Quotes can come in higher: on the NJ Woods & Water forum a New Jersey homeowner reported phone quotes of $2,500 to $4,000 for a 40-gallon gas tank on July 27, 2026. A fair quote names the model, the gallons, the warranty, the permit, and haul-away as separate lines.
Do I need a permit to replace a water heater in NJ?
Yes. New Jersey's Uniform Construction Code lists the replacement of existing water heaters with new ones of like capacity as minor work (N.J.A.C. 5:23-2.17A(c)2). Minor work can start once the local construction office has been given notice, the permit application has to be filed within five business days of that notice, and the work is inspected. Replacing a water heater is not on the code's ordinary plumbing maintenance list at N.J.A.C. 5:23-2.7, which is the list of jobs that need no permit.
What size water heater do I need for a 2,000 square foot house?
The published sizing tables go by people and hot-water use, not square feet. HomeGuide lists 23 to 30 gallons for 1 to 2 people, 36 to 40 for 2 to 3, 40 to 60 for 3 to 4, and 50 to 80 for 5 or more. Angi's table puts a 40-gallon tank at 1 to 4 people and a 50-gallon at 3 to 5. ENERGY STAR says to start from the capacity of the tank you have now, printed on its nameplate or yellow EnergyGuide label, and that you may want a larger unit if you have added people or fixtures.
How much does Lowe's charge to install a water heater?
Lowe's does not publish a flat installation price. Its water heater installation page, read October 1, 2026, says the cost varies with the type of heater, the fuel source, and local labor and permit fees, and that an independent installer gives the quote during a free consultation. The page says a basic installation covers disconnecting the old unit, the permit unless local rules make it the customer's job, a same-location and same-fuel replacement, testing, and disposal, with extra fees for same-day, weekend, attic, or crawlspace work. Lowe's will not install a water heater you already bought; the heater and the labor are sold together.
Does PSE&G replace water heaters, and does WorryFree cover it?
PSE&G WorryFree sells and installs A.O. Smith gas and electric water heaters through licensed contractors, gives a free replacement estimate by phone at 1-800-539-7734, and lets you pay over up to 72 months on the PSE&G bill, subject to credit approval. That is a purchase. The WorryFree protection plan is a different product: $4.55 a month for a standard water heater and $13.03 for a gas tankless one on October 1, 2026, and the plan terms list water heater tank failure or leakage among the parts not covered. A plan does not pay for a new tank.
Is there a PSE&G rebate on a new water heater?
Only on high-efficiency models installed by a PSE&G participating contractor. PSE&G's HVAC Instant Rebates table, read October 1, 2026, lists $240 on a power-vented gas storage water heater, $300 or $450 on a tankless unit depending on efficiency, $150 on an indirect tank tied to a 90% boiler, and $450 on a heat pump water heater, or $750 when the heat pump water heater replaces a fossil-fuel storage or tankless water heater. Elizabethtown Gas and New Jersey Natural Gas pay $400 on a power-vented gas tank, $500 or $750 on a tankless unit, and $250 on an indirect tank. A standard gas tank that vents into a chimney is on none of those tables.
Should I replace a 20-year-old water heater?
At 20 years a tank is past every published service-life range we found. PSE&G WorryFree's FAQ says a water heater should last about six to 12 years with proper maintenance, New Jersey Natural Gas recommends replacing a tank every 10 to 15 years, and Lowe's says most units last about 10 to 15 years. HomeGuide's rule of thumb is to consider replacing a water heater over 10 years old, or when a repair costs more than half of a replacement. HomeGuide adds that replacing a water heater before it fails may prevent leaks and water damage.
Do you need a plumber to replace a water heater in New Jersey?
In almost every case, yes. N.J.A.C. 5:23-2.15(b)2 says plumbing work shall not be undertaken except by persons licensed to perform it, with one exception: a single-family homeowner working on his or her own dwelling. The licensed plumbing contractor's seal and signature go on the plumbing permit application. The State Board of Examiners of Master Plumbers licenses master plumbers and can be reached at (973) 504-6420; anyone can look a license up on the State's verification site.
Is there a federal tax credit for a water heater in 2026?
No. The IRS says the Energy Efficient Home Improvement Credit (Section 25C) will not be allowed for any property placed in service after December 31, 2025, and ENERGY STAR's heat pump water heater credit page says the credit was effective for products purchased and installed between January 1, 2023 and December 31, 2025. A water heater installed in 2026 does not earn it. The utility rebates on this page are separate programs.
Does LA Trusted Partners install water heaters?
No. LA Trusted Partners is a New Jersey referral network, not a plumbing contractor and not a dispatcher. A request on this page is reviewed, and only when approved coverage is confirmed are your details shared with an independent plumber who contacts you directly. LA Trusted Partners does not set, quote, or guarantee any plumber's pricing, arrival time, rebate eligibility, or workmanship.
