Where Can I Sell My Water Heater for Cash or Scrap?

The Short Version

• Working water heaters: If your tank is leak-free, clean, and less than eight to ten years old, list it on local classified sites like Facebook Marketplace, Craigslist, or OfferUp to get between $50 and $200 in fast cash.
• Broken or leaking tanks: If your unit has a punctured tank, rust holes, or heavy mineral buildup, haul it to a scrap yard (a local metal recycling facility that pays cash by weight) for $5 to $20 in metal value.
• Prep before moving: Never move a full tank. Always turn off the power or gas, connect a hose to the drain valve (a small faucet near the bottom of the tank used to empty water), and flush out all water to drop the weight from over 400 pounds down to around 100 pounds.
• Zero-effort option: If you cannot haul the tank yourself and do not care about pocket change, post a free curb alert online so a local metal collector picks it up from your driveway for nothing.

Working vs. Broken: Resale Value or Scrap Metal?

Before you take photos or load an appliance into your vehicle, you need to know if the tank has real resale value. A water heater that still works can help a landlord, a cabin owner, or a homeowner on a tight budget. A unit that leaks from the main body, however, has zero resale value and belongs straight in the recycling pile.

Start by looking at the manufacturer data plate on the side of the tank. This metal label lists the model number, fuel type, tank capacity, and serial number. Most brands hide the manufacture date inside the serial number. For example, the first four digits often represent the month and year or the week and year the factory built the tank. A tank under six years old is an easy sell. A tank between six and ten years old has modest value if it looks clean. Anything over ten or twelve years old is living on borrowed time, because the internal steel tank usually rusts through around this age.

Inspect the tank body closely to see which route makes sense:

• Check the lower seams and base: Look for rust flakes, peeling paint, or white mineral crusts around the bottom rim. If you see brown water trails or crusty salt deposits, the inner tank lining has failed. That tank belongs in scrap.
• Inspect the top fittings: If the rust is only on the top water nipples or around the brass fittings, those parts can be replaced. A clean, dry body with surface rust only at pipe connections still has resale potential.
• Check the anode rod: The anode rod (a sacrificial metal rod inside the tank that slows down rust) protects the steel walls from corrosion. If water is bubbling around the hex head of this rod on top of the tank, or if the tank was drained and rusty chunks poured out, the metal walls are thin and worn.
• Look at the fuel style: Tankless water heaters and hybrid heat pump units hold resale value much better than standard cylindrical tanks. Even an older tankless unit can fetch good money for replacement parts, circuit boards, or copper heat exchangers. Basic electric or atmospheric gas tanks drop in value much faster.
• Consider the location: Units designed for manufactured housing have specialized safety certifications and intake setups. If you have an appliance pulled from a trailer, contractors looking for a mobile home heater replacement often search local boards for affordable, code-compliant swaps.

Selling a Working Unit: Where to List and How to Price It

If your water heater passed inspection, selling it locally gives you the best return. Shipping a large steel tank across the country is out of the question due to freight fees. You want a local buyer with an SUV, van, or pickup truck who can hand you cash and carry the tank away themselves.

The three most active platforms for used appliances are Facebook Marketplace, Craigslist, and OfferUp. Facebook Marketplace works well because you can see buyer profiles and arrange daytime driveway pickups with real neighbors. Craigslist remains popular among independent handypeople, rental property managers, and plumbers looking for temporary backup units. OfferUp offers a solid mobile setup with built-in user ratings and map-based browsing.

Pricing your unit realistically keeps you from storing a massive metal cylinder in your walkway for weeks. A standard 40-gallon or 50-gallon electric or gas tank that sells for $600 to $900 brand new in stores will usually fetch $50 to $150 on the used market if it is under eight years old. If it is nearly new, such as a tank pulled during a remodel after only two or three years of use, you might get $200 to $300. Tankless models can sell for $200 to $500 depending on the brand and condition. Remember that buyers take a gamble when installing a used plumbing appliance, so fair prices seal the deal fast.

To write an effective listing, take clean, well-lit photos. Wipe away cobwebs and dust with a damp rag before photographing the unit. Take one photo of the whole tank standing upright, one close-up of the manufacturer data plate showing the gallons and date, and photos of the burner compartment or electric element access covers. In your description, state clearly whether it runs on natural gas, liquid propane, or 240-volt electric power. Mention why you took it out, such as switching to a larger tank or converting to tankless, because buyers want reassurance that you did not remove it due to a major leak. Always state that the transaction is cash only and that pickup requires the buyer to load the item.

Selling for Scrap: Steps to Get Paid at a Metal Yard

When a water heater is rusted through, leaking from the tank shell, or older than a decade, classified buyers will ignore it. Your best path to cash is a scrap yard (a local metal recycling facility that pays cash by weight). Scrap facilities buy appliances to shred them, melt the metal down, and sell raw material to manufacturing mills.

1. Locate local metal yards and call ahead: Search for scrap metal recycling yards in your area. Call their main desk and ask if they accept residential water heaters. Some yards take whole appliances as shred metal or light iron, while others ask that you strip non-metal fittings first. Ask what their current pay rate per pound is for light iron so you know what to expect.
2. Separate your metals to maximize cash: A standard water heater is mostly heavy steel, which brings a lower price per pound. But the extra fittings attached to the unit are often copper, brass, and aluminum, which command far higher prices. Use a pipe wrench to twist off the brass drain valve at the base and the temperature and pressure relief valve near the top. Cut off any leftover copper supply tubes sticking out of the inlet and outlet ports. Throw these brass and copper pieces into a small bucket so the yard can weigh them separately from the steel body.
3. Secure the tank for transport: An empty water heater is top-heavy and rolls easily. Place the tank flat in a truck bed or on an open utility trailer. Run heavy-duty ratchet straps across the body, hooking them to the bed anchors, and tighten them down until the cylinder cannot roll or slide. Never let an unrestrained steel tank ride loose in an open bed.
4. Drive onto the commercial scale: When you arrive at the scrap yard, follow the signs for the vehicle scale. Stop on the large metal platform so the scale operator can record your gross vehicle weight. The attendant will tell you over an intercom or through a window where to unload.
5. Unload at the light iron pile: Drive to the designated appliance pile. You will drop the tank onto the ground, or an operator with an industrial magnet crane will pull it from your truck bed. Hand your separate bucket of brass and copper to the non-ferrous scale attendant so they can weigh those metals on a smaller counter scale.
6. Weigh out and get your cash: Drive back onto the main truck scale to record your empty vehicle weight. The computer subtracts your empty weight from your arrival weight to figure out the exact steel tonnage you dropped off. Park your truck, walk into the cashier booth with your driver's license, and collect your cash or voucher.

Prep and Safety: Draining, Disconnecting, and Staging

Never try to move or sell a water heater while it still holds water. Water weighs roughly 8.3 pounds per gallon. A standard 50-gallon tank holds over 415 pounds of water on top of its 100-pound steel body. Trying to lift a full unit can snap plumbing joints, flood living areas, and cause serious muscle strains. Follow these orderly steps to prep the tank safely.

1. Shut down power and fuel: For an electric water heater, walk to your main electrical panel and switch off the dedicated double-pole circuit breaker. For a gas heater, turn the gas control knob on the tank to the off position, then turn the yellow manual shutoff handle on the gas line perpendicular to the pipe. If you have been prepping appliances in an unheated workspace or outbuilding, running a steady garage heater keeps the space warm enough so damp floors dry out quickly during the job.
2. Close the cold water supply: Locate the cold water shutoff valve above the tank on the incoming pipe. Turn the wheel clockwise until it stops, or flip the lever handle 90 degrees to shut off incoming municipal water pressure.
3. Attach a garden hose to the drain: Thread a standard garden hose onto the drain valve (a small faucet near the bottom of the tank used to empty water). Run the other end of the hose to a floor drain, an exterior driveway, or a basement sump basin. If the water inside the tank is still hot, let it cool for a few hours first to avoid scalding your hands or softening garden hose rubber.
4. Break the internal vacuum: Turn the drain valve counterclockwise using a flat-blade screwdriver or the valve handle. Water will only trickle out at first because the sealed tank creates a vacuum, like holding your finger over the top of a drinking straw. Open the hot water faucets on an upstairs bathroom sink, or gently pull up the lever on the brass temperature and pressure relief valve near the top of the tank. Air will rush inside, and water will begin flowing freely out of the hose.
5. Disconnect lines and clear the space: Once the tank is completely hollow and dry, disconnect your garden hose. Unscrew the water flex lines from the top ports with an adjustable wrench. For electric units, unscrew the wiring cover plate, verify the cables carry zero current with a non-contact voltage tester, untwist the plastic wire nuts, and loosen the clamp holding the wire into the junction box. For gas units, carefully disconnect the flexible metal fuel line from the control valve using two wrenches working in opposite directions.
6. Move the tank using an appliance hand truck: Strap the dry tank securely to a two-wheeled appliance dolly using the integrated cinch strap. Tilt the dolly back onto its wheels and walk backward down ramps or across garage thresholds. Never drag the bottom steel lip across linoleum, tile, or finished concrete, because the sharp edges can leave gouges.

Alternatives: Free Curb Pickup, Rebates, and Haul-Away

Selling an appliance for cash takes effort. You have to answer messages, schedule appointments, handle negotiations, or spend an hour hauling metal to an industrial yard. If your primary goal is reclaiming floor space in your basement or garage, consider these alternatives to see which matches your schedule and physical comfort.

A free curb alert is the easiest choice if you do not have a vehicle that fits a tank. Post a listing on Craigslist under the free section or on Facebook Marketplace with the headline "Free scrap metal at curb." Include your street name and a clear picture of the tank sitting near the road. Independent metal recyclers drive residential neighborhoods daily looking for scrap to combine into full truckloads. In most suburban and urban areas, a steel tank placed on the curb disappears within two to four hours without you having to lift a finger.

Installer haul-away is another convenient path if you are buying a replacement. Most plumbing contractors and big-box store delivery crews offer an appliance haul-away service for a modest fee, usually between $40 and $80. The installers handle the disconnection, carry the heavy tank up your basement stairs, load it into their work truck, and take care of recycling. If you lack hand trucks, tie-down straps, or physical help, paying the installer saves your back and your weekend.

Check also with your regional electric or gas utility company before getting rid of the unit. Many electric utility providers run energy-efficiency programs that offer cash rebates or bill credits for retiring old, inefficient appliances. While standard steel water heaters rarely qualify for large bounties, older hybrid heat pump water heaters sometimes earn rebate checks between $50 and $100 through clean-energy recycling initiatives. Review your local utility provider's website to see if an appliance pickup bounty applies in your zip code.

FAQs

How much money will a scrap yard pay for an old water heater?

A typical residential steel water heater weighs between 80 and 150 pounds when completely empty. Scrap yards pay for these units based on the current market rate for light iron or shred steel, which generally results in a payout between $5 and $20 total. If you take the time to remove brass valves and copper stub pipes with a pipe wrench, you can sell those higher-value metals separately for an additional $5 to $10.

Will a scrap metal yard come pick up my water heater from my house?

Commercial scrap yards do not send collection trucks to residential homes for a single domestic appliance because the fuel and labor cost far more than the metal is worth. However, you can easily find independent local scrappers who will pick it up for free. Posting an online classified ad under the free section will alert nearby metal collectors who are happy to haul it away to combine with their own scrap loads.

Can I sell my old water heater back to Home Depot or Lowe's?

Home improvement stores do not buy used appliances or offer buyback cash for old plumbing hardware. When you purchase a new water heater and pay for store installation services, they may offer an optional haul-away service for an extra fee. In that scenario, the installation crew disposes of the old tank for you, but the store does not give you cash or store credit for the retired unit.

Is it legal to sell a used gas water heater to another homeowner?

Selling a used gas appliance privately is legal in most areas, but municipal building codes often dictate what can be reinstalled inside a home. Many cities require licensed plumbing permits to connect gas equipment, and some local energy regulations forbid installing older, low-efficiency tanks. Always be honest about the unit's age and condition so the buyer can verify local building requirements before taking it home.
