Radiator Removal Cost: What You'll Actually Pay [2026]

The cost to remove a home radiator depends on the radiator type, how many you're removing, and whether you're keeping or replacing the heating system.

Single radiator removal by a plumber costs $250 to $500 per unit. The plumber drains the heating system, disconnects the radiator from the supply and return pipes, caps the pipe ends, and removes the unit. Reddit users report budgeting about $400 per radiator for professional removal.

Multiple radiator removal brings the per-unit cost down. If you're removing 5 to 10 radiators as part of a renovation, plumbers often charge $150 to $300 per additional unit after the first because the system only needs to be drained once.

Full system conversion from radiator heat to forced air is a much larger project. Removing all radiators plus the boiler and installing new ductwork, a furnace, and an AC unit runs $15,000 to $25,000+ according to Reddit users who've done the conversion.

Yes, DIY radiator removal is one of the easier home improvement tasks if you're comfortable with basic plumbing. The key is properly draining the heating system first.

For a hot water (hydronic) system, shut off the boiler and let the system cool completely. Close the supply and return valves on the radiator you're removing. Place a bucket under the bleed valve, open it, and drain the radiator. Once empty, use two wrenches to disconnect the radiator from the supply and return pipes. Cap the pipe ends with threaded caps from any hardware store ($3 to $5 each).

For a steam system, the process is similar but you must wait until the system is completely cold and depressurized. Steam radiators are connected at a single pipe (one-pipe system) or two pipes. Close the valve, let it cool overnight, then disconnect.

The hardest part is moving the radiator, not disconnecting it. Cast iron radiators weigh 60 to 500 pounds. A large floor-standing unit may need to be tilted onto a furniture dolly or hand truck. Protect your floors with plywood or moving blankets — cast iron will crack tile and gouge hardwood.

• •Number of radiators — The first radiator is the most expensive because the system must be drained. Additional units on the same system are cheaper at $150 to $300 each.

• •Radiator material and size — Cast iron units weighing 200+ pounds require more labor than 30-pound steel panels. Some cast iron radiators are painted over with lead paint, adding hazardous material handling costs.

• •Floor level — Ground-floor radiators are straightforward. Second- or third-floor radiators must be carried down stairs, adding $50 to $150 per unit.

• •Pipe capping method — Simple threaded caps cost $3 to $5 per pipe. If the pipes need to be cut and soldered closed because of damaged threads, expect $75 to $150 more per radiator.

• •System type — Hot water systems are simpler to drain and disconnect. Steam systems require more care to avoid burns and pressure issues.

• •Keeping the system active — If you're removing some radiators but keeping others, the plumber must rebalance the system after removal. This adds $100 to $300 to the total job.

Cast iron radiators have modest scrap value. At current prices of roughly $0.03 to $0.08 per pound for cast iron (April 2026), a medium 12-pound radiator earns about $3 to $4 at the scrap yard according to First Quarter Finance.

Larger floor-standing radiators weighing 200 to 500 pounds could net $6 to $30. Not a huge windfall, but enough to cover a dump fee.

Aluminum radiators have better scrap value at $0.25 to $0.50 per pound. A 30-pound aluminum radiator is worth $7 to $15.

The real question is whether the scrap value justifies the effort of transporting heavy cast iron to a yard. For most homeowners, it makes more sense to book Dropcurb for $79 curbside pickup and save the time and vehicle wear.

Some scrap metal haulers on Craigslist will pick up cast iron radiators for free if you have several. The combined weight makes the trip worthwhile for them.

• •DIY disconnect + curbside pickup — Drain the system yourself (free), disconnect and move radiators to the curb, then book Dropcurb for $79. Saves $170 to $420 per radiator compared to professional removal.

• •Remove multiple radiators at once — Plumbers charge less per unit when removing several at a time since the system only drains once. Removing 5 radiators might cost $1,000 to $1,500 total versus $1,250 to $2,500 individually.

• •Post them for free on Craigslist or Facebook — Working cast iron radiators are valuable to renovators and vintage home enthusiasts. Someone may pick them up from your home at no cost to you.

• •Check municipal bulk pickup — Many cities accept radiators for free bulk pickup. Wait times are 2 to 8 weeks, but the price is right.

• •Call scrap haulers — Metal scrap haulers often pick up radiators for free if you have enough weight to make the trip worthwhile.
