Camco 04363 RV Water Heater Element 1500W 120V

When your RV or home water heater stops making hot water, a burned-out heating element is the usual suspect. The Camco 04363 is the replacement part that gets you back to hot showers. It's a 1500-watt, 120-volt universal flange element built to drop into most tank-style electric water heaters that use a 9-inch or larger tank diameter.

This is a high watt density element, which is the most common type and the same style that ships as original equipment on most water heaters. High watt density means the heating surface packs more power into a shorter element, so it heats a tank quickly and fits where space is tight. If the element you're pulling out was the factory unit, odds are good this is a straight match on wattage and style.

The build is what you want in a part that lives inside a tank for years. The heating loop is copper tubing packed with magnesium oxide insulation and finished with nickel plating. That combination resists scale and corrosion, which is the enemy of any immersion element. Hard water and mineral buildup are what kill elements early, and the nickel plating buys you time. Camco includes the gasket in the box, so you're not making a second trip for the seal when you go to reinstall.

The universal flange mounting pattern is the key to this part. Rather than a screw-in thread, the flange bolts to the tank face with the supplied gasket sealing it. That flange design fits most major residential and RV water heater brands, so you don't have to chase down a proprietary part number for your specific tank. If your old element bolted on with a flange and four screws, this one goes right back in the same way.

Before you order, match two numbers: voltage and wattage. This element is 120 volts and 1500 watts. Your replacement has to match the voltage and wattage of the element you're removing, and you should never exceed the nameplate rating printed on the water heater itself. Running a mismatched element is how you trip breakers, overheat wiring, or cook the new part. If your nameplate calls for 120V and 1500W, you're in the right place. If it calls for something else, that's a different element.

Not sure the element is actually the problem? The classic signs are no hot water at all, or water that never gets past lukewarm no matter how long you wait. An element that's failed open won't heat, and one that's caked in scale heats slowly and burns out sooner. A cheap multimeter across the terminals tells you fast: an open reading means the element is done. If yours checks out bad, the 04363 is the fix.

Swapping an element isn't a hard job, but respect the basics. Kill the power at the breaker before you touch anything. Drain the tank below the element port so you don't flood the compartment. Then it's a matter of unbolting the old flange, cleaning the mating surface, seating the new gasket, and bolting the 04363 in place. Refill, bleed the air, and restore power. Most boaters and RV owners can knock this out in under an hour with basic hand tools.

One fitment note worth repeating: the 9-inch minimum tank diameter. The universal flange needs a tank face at least 9 inches across to seat properly, which covers the vast majority of standard electric water heaters. If you're working on an unusually small tank, measure first. For the typical RV or residential electric heater, you're well within spec.

Who's this for? RV owners running an electric water heater, folks with a small utility tank at home, and anyone keeping a spare in the parts bin. A dead element always seems to happen at the worst time, so a lot of full-timers carry one just in case. The packaging is labeled in English and French, which is handy if you're crossing into Canada. It's a simple part that does one job and does it reliably, and it's cheap insurance against a cold shower.
