How to dispose of cast iron radiators: drain them, then sell them to architectural salvage dealers or radiator restorers if they are attractive and intact, or take them to a scrap yard, where cast iron is paid by weight. Radiators are very heavy, often a few hundred pounds each, so plan the move carefully. Old radiator paint may contain lead, so avoid sanding or stripping it before disposal.
Options
| Radiator type | Best option |
|---|---|
| Ornate, intact cast iron | Architectural salvage, restorers, online listings |
| Plain, working cast iron | Salvage, reuse, or scrap |
| Cracked or leaking | Scrap yard |
| Steel panel or baseboard | Scrap metal |
| Copper and aluminum fin baseboard | Scrap, often higher value per pound |
Draining and disconnecting
- Turn off the boiler and let the system cool.
- Close the valves and drain the radiator into a bucket or pan; water may be dirty and rusty.
- Disconnect the unions with large wrenches; old fittings may be stuck.
- Cap or plug pipes if the system stays in use. A plumber or heating contractor can help.
Steam and hot water systems differ, so get professional help if unsure.
Weight and moving
Cast iron radiators commonly weigh dozens of pounds per section, so a full radiator can weigh 100 to 400 pounds or more. Tips:
- Use an appliance dolly and straps.
- Tip the radiator onto the dolly carefully; legs can snap.
- Use ramps and multiple helpers. See rolling a heavy appliance up a ramp.
- Protect floors and stairs with plywood.
Scrapping
Scrap yards usually classify radiators as cast iron. Prices fluctuate. Remove valves and brass fittings to sell separately if you want maximum value. See scrap yard versus landfill for clean metal.
Lead paint cautions
Many old radiators have multiple layers of paint, some containing lead. Do not sand, grind, or burn paint off. If you must handle flaking paint, use wet methods and protective gear. See handling lead paint debris.
Salvage value
Decorative radiators from older homes can sell to restorers, salvage stores, and homeowners restoring period houses. Measure and photograph them for listings.
Replacing the system
If you are removing the whole boiler system, the boiler is also scrap metal. See retiring a home furnace.
Hiring removal help
Junk haulers, scrap collectors, and some salvage buyers will remove radiators for free or a fee, sometimes paying for valuable units. For upper floors, professional help reduces the risk of injury and damage.
Old system water
Water drained from old heating systems is often dark, rusty, and may contain treatment chemicals. Drain it into a floor drain or sink connected to the sewer where allowed, not onto lawns or into storm drains.
