Keeping Your Infrared Heaters Safe in Wet Zones
Putting infrared lamps in a bathroom or an outdoor area isn’t as simple as just slapping on a waterproof cover. You’re mixing high wattage with moisture—and as we all know, that’s a recipe for trouble. If you want a setup that actually stays safe, you have to obsess over where the heating element meets the power supply. The battle against steam You’ll see “IP66” thrown around a lot. Sure, that means the housing can handle dust and a blast of water from a hose. But the real enemy? Condensation. In a steamy shower, moisture doesn’t just fall; it settles. It clings to the terminals. To stop electricity from “creeping” across those damp surfaces and hitting the chassis, we use high-temp silicone gaskets and sealed cable glands. Without them, your breaker is going to trip. Often. Dealing with the “stretch” Here is the tricky part: heat makes things move. When a shortwave lamp kicks in, the quartz tube and the metal housing expand at different speeds. If everything is bolted down tight, those seals will just crack under the pressure. That’s why we use floating mounts. It gives the lamp room to breathe. If a seal pops, moisture gets in, and the whole unit shorts out. Simple as that. The hidden trade-off There is a catch, though. When you seal a unit tight to hit those IP66 standards, you’re essentially creating a heat trap. The air inside gets hot—much hotter than it would in an open-frame heater. You have to make sure the outer shell has plenty of surface area to bleed off that heat. If you don’t, you’ll eventually cook your own wiring insulation. And for heaven’s sake, wire it to a dedicated GFCI. Even with the best build in the world, that GFCI is the only thing standing between a minor glitch and a very bad day.
