Camco 02103 1000W 120V Screw-In Water Heater Element

When the hot water goes cold on your boat or in the RV, a burned-out heating element is usually the first thing to check. The Camco 02103 is a screw-in replacement element rated at 1000 watts and 120 volts, built to drop into most standard tank-type water heaters that use a screw-in element port. It's the same style of high watt density element that ships in most new heaters, so for a straight swap you're back to hot showers without reinventing your plumbing.

The element is made from copper tubing with a magnesium oxide insulation core and a nickel-plated finish. That construction matters where water quality is hard on hardware. Copper transfers heat quickly and evenly, the magnesium oxide packs the resistance wire so it heats consistently along the full length, and the nickel plating helps the element shrug off the corrosion that eventually kills a bare element. It's a proven recipe, and it's why this style has been the standard for decades.

High watt density just means the heat is concentrated over a smaller surface area, which is the most common design and the type most heaters leave the factory with. For most owners that's exactly what you want in a replacement. It matches what was already in the tank, so the heater behaves the way the manufacturer intended. The one rule to follow is simple. The replacement element has to be the same voltage and wattage as the one you're pulling out, and you should never exceed the nameplate rating stamped on the water heater. This one is 120 volt, 1000 watt. If your old element reads the same, you're good.

Fitment comes down to the port style and the tank. This is a screw-in element, so your heater needs a threaded screw-in port rather than a bolt-in flange. It's sized for tanks with a minimum 8 inch diameter, which covers the vast majority of compact RV, marine, and point-of-use heaters as well as full-size tanks built after the mid-1990s. If you can back the old element out with an element wrench and it threads in, this one threads in the same way.

A fresh gasket is included, so you're not hunting for a seal at the parts counter. That's the part people forget, and reusing an old, compressed gasket is how you end up with a slow drip behind the access panel. Install the new element with the new gasket, snug it down, refill the tank completely before you restore power, and you're set. Camco packs detailed instructions in the box that walk through pulling the old element and setting the new one, so even if this is your first element swap it's a manageable afternoon job.

A couple of real-world notes from the dock. Always kill the power at the breaker before you touch anything, and confirm the tank is full before the element is energized. Running a dry element even for a few seconds is the fastest way to burn out a brand new one. And if your heater has been giving you lukewarm water rather than none at all, that's often a partially failed element or a tripped thermostat, so it's worth testing the element for continuity before you assume the worst.

The 02103 is UL listed for the United States and Canada and carries a 1 year limited warranty. It's an inexpensive part that gets a water heater back in service fast, which is exactly what you want when the family's waiting on a hot shower at the end of a long day on the water. Keep one in the spares bin if you cruise or camp off the grid, because element failures never happen at a convenient time.
