How much does it cost to replace a water heater in 2026?

Installed cost by type

HomeGuide's January 2026 figures, based on estimates its members receive^[1]:

Type	Unit only	Installed
Standard tank (40 to 50 gal)	$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 (boiler-fed)	$1,500 to $3,000	$2,000 to $4,500
Solar	$1,000 to $6,000	$3,000 to $9,000

Installed cost by tank size

Tank size	HomeGuide installed (Jan 2026)[1]	ProjectCostPro gas, full scope (Jul 2026)[2]	ProjectCostPro electric, full scope[2]
30 gal	$500 to $1,900	n/a	n/a
40 gal	$600 to $3,000	$2,600 to $4,500	$2,550 to $4,400
50 gal	$700 to $3,100	$2,900 to $5,050	$2,700 to $4,650
75 gal	$1,100 to $3,600	$3,050 to $5,550	n/a
80 gal	$1,200 to $4,000	n/a	$2,850 to $5,150

Why the two sources disagree

They measure different jobs. HomeGuide's ranges reflect estimates homeowners report, including simple swaps where nothing else changes^[1]. ProjectCostPro's ranges are calculator outputs for a like-for-like swap that includes removal of the old unit, an expansion tank, a drain pan and a permit, with contractor markup^[2]. If your current install already has an expansion tank and pan and meets code, expect the lower range. If it is an older install that needs upgrades, expect the higher one.

Either way, these are national ranges, not quotes. Labor rates and permit fees vary a lot by city.

What drives the price

HomeGuide's line items for a tank replacement^[1]:

Item	Typical cost
Labor for a standard tank install	$200 to $1,000
Removal and disposal of the old unit	$75 to $500 (often included)
Expansion tank	$100 to $400
Bringing the install up to code	$75 to $500 or more
Permits for gas or electrical work	$50 to $200
Moving the heater to a new location	$500 to $2,500
Difficult access (attic, tight closet)	$125 to $300 per extra labor hour

Other things that move the total:

• Switching fuel or type. Electric to gas means a gas line and venting. Tank to tankless often means a larger gas line, new venting, and sometimes electrical work. See tankless costs.
• Size. Bigger tanks cost more and take longer to install^[2].
• After-hours service. Emergency and weekend installs carry extra charges^[1].

Permit fees: a real example

Permit costs are set locally. Houston publishes its water heater permit fee: $34.24 for the first three heaters and $11.41 per heater after that, plus a $33.56 admin fee, and the fee table lists a $97.56 minimum permit fee (another line on the same page says $91.05)^[3]. The permit must be obtained by a master plumber registered with the City of Houston^[3]. A legitimate quote should include the permit.

Rebates and credits in 2026

• No federal 25C credit. The IRS says the Energy Efficient Home Improvement Credit is not allowed for property placed in service after December 31, 2025^[4]. Some cost guides still mention it. See 25C status.
• Utility rebates still exist in some areas. Examples we confirmed: Nicor Gas pays $225 for a qualifying ENERGY STAR gas tank (UEF .86 or higher) and $150 for a qualifying tankless (UEF .95 or higher) installed in 2026^[5]. Austin Energy pays $1,000 for a qualifying ENERGY STAR heat pump water heater^[6]. ComEd pays $750 for an ENERGY STAR heat pump water heater purchased July 1 to December 31, 2026^[7]. Each has conditions and deadlines; read them before you buy.

How to compare quotes

Ask each contractor for a written scope that lists: the exact model and its first-hour rating, removal and disposal, expansion tank, drain pan, venting and gas connector work, the permit, and the labor warranty. Quotes that leave out the permit or code items are not cheaper; they are incomplete.

When to call a pro

• Any replacement: the install involves gas, venting or 240-volt work and usually a permit.
• Changing fuel, size class or location.
• An older install with no expansion tank or drain pan.
• To get a firm price: national ranges cannot price your specific install.
