Why we put our IP65 heaters through the wringer
Putting an infrared heater in a bathroom is a bit like putting a high-powered appliance in a steam room. You’ve got massive temperature swings and humidity that never seems to go away. Now, we could just point to an “IP65” rating on a spec sheet and call it a day. But spec sheets don’t tell the whole story. That’s why we run damp-heat aging tests. We basically try to break our own heaters so they don’t break in your home. Here’s the thing about moisture: it’s sneaky. An IP65 rating means the unit can handle dust and a few splashes of water. But bathrooms are full of water vapor. Vapor molecules are tiny—way smaller than a droplet—and they can slip through seals that look perfectly tight. Once that moisture gets inside to the circuitry or the lamp terminals, things get messy. You get oxidation. That leads to electrical resistance, which causes flickering, annoying hotspots, or a heating element that just gives up the ghost. To stop that, we put our heaters through a brutal cycle of heat and humidity for hundreds of hours. We’re looking for “creepage”—that’s when electricity starts jumping across surfaces because they’ve become contaminated. We poke and prod at the quartz tube seals and the housing gaskets. If something degrades or a wire starts to corrode, we find it in the lab. It’s a bit of a balancing act, though. If you seal a heater too tightly to keep the water out, you create a heat trap. Since we have to limit some of the ventilation for the sake of the waterproof seal, the internal parts actually run hotter than they would in a giant industrial warehouse. To fix this, we use specific heat-sink materials. They pull the heat away from the electronics without opening any holes for the steam to get in. At the end of the day, a failure in a bathroom isn’t just a nuisance. It’s a safety risk. We’d much rather find the breaking point in our lab than have a unit fail in your customer’s ceiling.
