Why we put our IP65 heaters through a “torture test”
Bathrooms are honestly a nightmare for heating elements. You’ve got steam everywhere, random water splashes, and temperatures that swing from freezing to sauna-hot in minutes. Now, we build our infrared lamps to IP65 standards, but a label on a box doesn’t actually mean anything in the real world. That’s why we put every single batch through damp-heat aging tests before they even touch a shipping pallet.
The problem with vapor
Here’s the thing: an IP65 rating means the unit can handle dust and water jets. But in a bathroom, the real killer isn’t a splash of water—it’s the vapor. Steam is sneaky. It gets into seals way easier than liquid water does. Once it sneaks inside, it settles right on the electrical terminals and the quartz glass. If that seal gives way, moisture hits the live components. That leads to “tracking,” which is basically electricity crawling across the insulation until—pop—you’ve got a short circuit or a blown fuse. We’d much rather that happen in our lab than in your customer’s house.
We don’t just soak them; we cycle them
We don’t just leave the heaters in a damp room. That’s too easy. Instead, we blast them at full power in a high-humidity chamber, then we kill the power instantly. This creates a “pump effect.” As the unit heats up and cools down, it literally breathes, sucking moist air in and out of the housing. We’re looking for any sign of a gasket shrinking or a solder joint cracking. It’s simple: the seal either holds, or it doesn’t. There’s no middle ground.
One small catch
There is a trade-off, though. To make these things survive the damp, we have to seal them incredibly tight. Because they’re so airtight, the heat stays trapped inside. This means the internal components run hotter than a standard heater would. Just make sure you leave enough breathing room during installation so the housing doesn’t overheat.
