The contractor who installed your new unit might offer disposal, but often for a premium fee. You can save money by dismantling it for scrap, recycling it, or donating it. If you are handy, you might even repurpose the tank for a backyard project.
In this article, we will guide you through how to safely remove and dispose of your old water heater, including options for recycling and repurposing.
Key Takeaways
- Safety First: Always disconnect the power (gas or electric) and fully drain the tank before attempting to move it.
- Recycling Options: You can take the unit to a recycling center, schedule a bulk pickup with your city, or donate working units to charity.
- Scrap for Cash: Disassemble the heater to sell copper, brass, and steel components to local scrap yards.
- Repurpose It: Creative DIYers can turn old tanks into smokers, solar heaters, or garden planters.
How To Remove an Old Water Heater
Before you can scrap or recycle the heater, you have to get it out of your house safely. This is heavy work, so grab a partner if possible.
1. Cut the Power Supply
Safety is the priority here. You must disconnect the energy source before touching anything else.
Gas Water Heaters
Locate the gas shut-off valve on the supply pipe leading to the heater. Turn the lever 90 degrees so it is perpendicular to the pipe. This cuts the gas flow.
Electric Water Heaters
Go to your main circuit breaker panel. Find the breaker labeled “Water Heater” and flip it to the “Off” position. If the circuit isn’t labeled, use a non-contact voltage tester to ensure the power is truly off at the unit.
Remove the access cover on the heater and test the wires. If the voltmeter shows no reading, you are safe to proceed. If you are uncomfortable working with electricity, stop and call a professional.
2. Drain the Tank
Water is heavy, so you need the tank empty. Locate the cold water inlet valve at the top of the tank and turn it off.
Next, go into your house and open the hot water faucets in your sinks and tubs. This breaks the vacuum seal in the pipes and prevents air lock, allowing the tank to drain smoothly.
Attach a standard garden hose to the drain valve at the bottom of the heater. Run the other end to a floor drain or out into the driveway. Open the drain valve carefully. Be cautious, as the water coming out may still be scalding hot.
3. Disconnect and Remove
Once empty, use a pipe wrench to disconnect the water lines and the vent pipe (for gas units). If the pipes are soldered copper, you may need a hacksaw to cut them free.
Tilt the heater onto a heavy-duty appliance dolly. Strap it in securely. These units can weigh 150 pounds or more, so move slowly to avoid injury or damage to your home.
Recycling and Disposal Options
Once the heater is out of the house, you need to decide where it goes. Here are your best options:
1. Recycling Centers
Most metal recycling facilities will accept water heaters. They shred the units to recover steel, copper, and brass.
Some centers pay a small amount based on the weight of the steel, while others may charge a nominal fee for drop-off. Call ahead to check their policies. You will likely need a valid ID, as scrap theft laws are strict in many states.
2. Municipal Bulk Pickup
Check your local waste management website. Many cities offer “bulk waste” pickup days once a month or by appointment. This is often free or included in your utility bill. You typically just haul the unit to the curb on the designated day.
3. Donate to Charity
If you replaced the heater for a remodel but it still works perfectly, don’t trash it. Organizations like Habitat for Humanity ReStore often accept building materials and appliances in good condition. You help a good cause and get a tax deduction receipt in return.
4. Scrap It Yourself
If you want to maximize the cash value, strip the valuable metals off the unit yourself before taking it to the yard.
- Test with a magnet: If the magnet sticks, it is steel (ferrous). If it does not stick, it is likely copper or brass (non-ferrous), which are worth more.
- Harvest the copper: Cut off any copper piping and pull the internal heating elements if they are copper.
- Grab the brass: Remove the drain valve and other fittings if they are brass.
- Gas valves: On gas units, the control valve often contains aluminum and mixed metals that can be sold.
5. Junk Removal Services
If you lack a truck or the physical ability to move the tank, hire a service like 1-800-GOT-JUNK or a local hauler. They will enter your home, carry the unit out, and handle the recycling for you. This costs money, but it is the most convenient option.
6. Online Marketplaces
List the unit on Craigslist, Facebook Marketplace, or OfferUp. If it works, list it for a low price. If it is broken, list it as “Free Scrap Metal.” Scrappers constantly patrol these sites looking for free appliances to pick up.
Reinvent Your Old Water Heater
If you are a DIY enthusiast, that steel tank is a blank canvas. Here are a few creative ways to repurpose it:
1. Build a Smoker or Grill
The thick steel walls of a water heater are perfect for retaining heat. This is a classic welding project.
Clean the tank thoroughly (ensure no glass lining insulation remains) and cut it to size. You can mount it horizontally for a classic offset smoker or vertically for a drum smoker. Add hinges, a grate, and a chimney. It is durable and works better than cheap store-bought smokers.
2. Create a Solar Water Heater
If the tank itself does not leak, you can strip the insulation and paint it matte black to absorb heat. Encase it in a glazed box to trap solar energy. This “batch heater” can pre-heat water before it enters your main system, significantly lowering your electric or gas bill.
3. Make a Garden Planter
Cut the tank in half lengthwise or crosswise to create industrial-style planters. They are deep enough for root vegetables or small trees. You can paint them to match your patio decor or let them rust slightly for a rustic look. Just remember to drill drainage holes in the bottom.
