We do not print a flat price for electric water heater replacement, because a swap in an accessible garage and a swap in a tight closet with new wiring are different jobs. Instead, we show what moves the number, so that a written estimate from a plumber near you makes sense when it arrives. The broader view of tanks sits in our hub for repairing and replacing water heaters and the general water heater replacement cost page.
What makes up the cost of replacing an electric water heater?
A quote adds up the unit itself, labor to pull the old tank and set the new one, parts like a fresh relief valve, flex connectors and a drain pan, a permit where one applies, and disposal of the old heater. The unit and the labor are normally the two largest lines, and the rest depends on your house.
The table shows how the lines usually break out and what pushes each up or down:
| Line on the quote | What pushes it up | What keeps it down |
|---|---|---|
| The water heater | Larger tank, longer warranty, heat pump model | Standard 40 or 50 gallon tank |
| Labor | Tight closet, attic or stairs, hard access | Garage with clear floor space |
| Electrical work | New circuit, wire upgrade, panel limits | Existing 240 volt circuit in good shape |
| Parts and code items | Expansion tank, new shutoff, drain pan, seismic strapping | Existing connections still in good condition |
| Permit | Required for most full replacements | Repairs inside the heater, no permit |
| Haul-away and disposal | Hard access, extra items | Usually included |
Read any dollar figure you find online as a guide only, and compare bids line by line, extras for the installation included. The real price rests on the exact unit, the access and the local rules, and only a written quote gives you a number you can rely on.
Does tank size change the price?
Yes. A bigger tank costs more to buy and to run, and a household that draws less hot water than it assumes can drop a size. A 40 to 50 gallon tank is typical in Valley homes. Large families, a soaking tub or a second bathroom group may justify more, and a small condo may need less.
Peak hot water draw sets the size, and square footage does not. Two adults in a two bedroom house seldom need what a family of five does. Before suggesting a size, a plumber should ask who lives there and when the showers run. Undersized tanks run cold, while oversized ones cost more up front and lose more heat standing idle.
Why can an electric water heater replacement need electrical work?
Electric tanks pull heavy current, so the wiring comes with the job. A same-type replacement normally reuses the existing 240 volt circuit, but undersized wire, a breaker that does not match the new unit's rating, or a damaged connection must all be corrected. Wiring is where quotes differ the most.
Older Valley ranch houses can have modest electrical panels. Going from gas to electric, or from a tank to a larger unit, may exceed the panel's room or capacity and add a new circuit. Heat pump water heaters bring their own needs, among them clear airflow around the unit, a condensate drain and sometimes a 240 volt circuit, so the electrical line on the quote may look different.
Tankless water heaters in electric form draw far more power than a tank. A simple swap can become a panel upgrade, as electric versus tankless water heaters explains.
Is a permit part of the price, and what code items get added?
On most full replacements, yes. In Burbank the Building Division issues permits, and LADBS covers the Los Angeles neighborhoods of the Valley. State law also says water heaters must be strapped or braced against earthquake movement, so a new tank normally goes in with strapping, and the plumber may add other code items such as a relief valve and drain line. Details are on our page about permits for water heater replacement.
According to the California Energy Commission, the 2025 Building Energy Efficiency Standards take effect on January 1, 2026. We have not verified which water heater types they affect. For a tank replaced in 2026 or later, ask the plumber how the current standards apply to your house and whether a heat pump model is required or merely optional.
When you are replacing the whole heater and the quote shows no permit line at all, ask the plumber why it is missing.
What does a written quote need to show?
A clear quote identifies the unit by brand and model, itemizes labor, parts, permit and disposal, and says if electrical work is covered. It should also explain what happens when the plumber meets a problem mid-job, such as a corroded shutoff or failing breaker, and how any added cost gets approved.
Questions to put before you accept:
- Is the price for the exact model named, or a similar one?
- Is the permit included, and who pulls it?
- Does it include the expansion tank, seismic strapping and a new relief valve and drain line if the code needs them?
- Does the price cover hauling the old tank away?
- What does the manufacturer's warranty cover, and is labor covered?
The state's contractor licensing agency advises verifying a contractor's license before hiring, and you can do that at cslb.ca.gov. The same site covers home improvement contracts, and its rules on written contracts and payments apply to larger jobs.
Is it cheaper to repair than to replace?
Frequently, yes, for a young tank with a failed thermostat or element. Age and condition decide it. Repair suits a heater with life left. Money spent on a tank that leaks, has rusted through, or is old enough that other parts will soon fail is usually wasted.
For help making that call, read how often a water heater needs replacing. A leaking heater is covered in water heater leak repair, and when only an element or thermostat has failed, the thermostat replacement guide describes the cheaper path.
Hard water builds scale faster on elements and the tank floor, cutting the life of electric tanks throughout the Valley. Burbank Water and Power, Glendale Water and Power and LADWP each publish a water quality report giving hardness for your supply, and it is worth reading before you pick a model.
How do I get a price for my house?
Tell us about the heater you have, its location and its age, and after a visit a local plumber will give you a written price. Start on the quote page. Nothing binds you until you accept the price. How the service works walks through every step, from your first question through the finished job.
Other work we handle across Burbank and the Valley appears on the Lankershim Plumbing home page.
Questions people ask
How much does it cost to replace an electric water heater?
Tank size, access, electrical condition and permit all play in, so no flat figure is printed. What you will really pay is whatever the quote says after a visit. Generally, a plain swap of a standard tank in an easy spot costs less than a job needing new wiring, a heat pump model or work in a tight attic.
How long does an electric water heater replacement take?
A few hours on site is typical for a simple replacement, covering draining the old tank, setting the new one, connecting, filling and testing. Wiring, a permit inspection or a hard-to-reach location adds time. Expect no hot water for part of that day, and a while longer as the new tank heats.
Is a heat pump water heater worth the extra cost?
Purchase and installation cost more, but electricity use is far below a standard electric tank, so it can pay for itself over time. It wants space and airflow and suits a garage or utility room best. Request a written comparison from the plumber, and ask your electric utility about rebates before you buy.
Can I replace an electric water heater myself?
A full replacement needs a permit in most cities, and the electrical connection carries 240 volts. Unless you are at ease with both and ready to pull the permit and pass inspection, hire a plumber with a California contractor license, and verify it yourself through the state licensing site. A weak connection can overheat, and a tank without bracing can topple in an earthquake.
Will the plumber haul away my old water heater?
Removal and disposal of the old tank are included in most quotes, but get that confirmed on paper. Old tanks are bulky, heavy and barred from household trash, so ask where yours goes. An inspector may also want the old unit gone before approval.
