Is a Water Heater Worth Scrapping?
Short answer: yes, but not for much unless you break it down — and never with water still in it. Here's what's inside, what it pays, and how to run your own numbers.
A water heater is one of the most common large appliances a scrapper runs into — every home has one, they get replaced every 8–12 years, and plumbers are often glad to have them hauled off. But “worth scrapping” needs a definition. As a payout per unit, it’s modest. As free metal you were going to move anyway, it’s a clear yes. Here’s the real picture.
What’s inside a water heater
Most of a water heater is exactly what it looks like: a big steel tank. That steel is 70–80% of the total weight and pays scrap-iron prices — pennies a pound. The value density is low, but the total weight is high (40–120 lb depending on size), so even at steel prices it adds up.
The better metals are small but real:
- Copper — heating elements (in electric units) and short pipe stubs and connectors.
- Brass — fittings, the drain valve, and the temperature/pressure relief valve.
Neither is a large percentage of the weight, but copper and brass pay several times what steel does per pound, so pulling them out is where the extra value lives.
Run your own numbers
Enter your water heater’s weight and your local prices — the calculator splits it into steel, copper, and brass and shows the estimated value. (It defaults to the water heater preset; you can switch appliances too.)
Your appliance
Steel tank dominates the weight; foam insulation and the plastic jacket make up most of the rest and have no scrap value. Draining the tank first is worth the trip to the yard alone — full tanks are often refused.
Typical range for this appliance: 40 lb–120 lb. Weigh it if you can.

The remaining ~22% is insulation, plastic, or other non-scrap material with no resale value.
Drain it first — this is not optional
A full 50-gallon tank holds hundreds of pounds of water. Yards will often refuse a water heater that hasn’t been drained, and hauling a full one is miserable and unnecessary. Open the drain valve (or just tip it out), let it empty completely, and you’ll be moving 50 pounds of steel instead of 500 pounds of steel and water. This single step is the difference between an easy scrap and a two-person wrestling match.
Whole vs broken down
Selling it whole is fast: the yard weighs it and pays an average price for a mixed steel-and-a-little-copper unit. Breaking it down — pulling the copper elements and brass valves to sell separately — pays more per pound on those pieces, because whole-appliance pricing assumes you left the good metal inside.
Whether the breakdown is worth it comes down to the same logic as everything in scrapping: how much extra you’d earn versus the time it takes. For one water heater, many scrappers just sell it whole. For a steady stream of them from a plumber contact, breaking them down starts to make sense. Weigh the unit whole first — that number, at your yard’s whole-appliance price, is the floor everything else has to beat.
Found several for sale?
If you’re looking at a lot of water heaters (or a mixed appliance haul) offered for a price, don’t eyeball it — run it through the Scrap Lot Deal Analyzer to make sure the asking price leaves you a margin after your local prices.
