Why we put our heaters through a “humidity boot camp”
If you’re putting an infrared heater in a bathroom or on a patio, you’re basically asking it to survive a war zone. Steam, splashes, damp air—it’s a lot. When these things fail, it’s almost always the same story: moisture sneaks past a seal or the electrical contacts start to rust. It’s frustrating, and frankly, it’s dangerous.
The “Bake” Test
Standard quality checks are fine for a toaster, but for wet zones? Not a chance. That’s why we use damp-heat aging tests. In plain English: we shove our heaters into high-humidity chambers and bake them for days on end. We’re trying to break them. We want them to fail in the lab so they don’t fail in your home. Here’s the thing about moisture—it loves to create electrical paths where they don’t belong. That leads to leakage currents. By stressing the units to their limit, we make sure the insulation actually does its job.
The Battle Against the Elements
We use quartz glass and some pretty heavy-duty seals to protect the tungsten filament. But there’s a catch. The spot where the glass meets the metal cap is a tricky bit. As the heater warms up and cools down, the materials expand and shrink. This can create tiny, microscopic gaps. If water vapor finds those gaps, the contacts corrode. We catch those flaws before the product ever leaves our floor. If a lamp can’t handle 95% humidity at 40°C for 500 hours, it has no business surviving a damp winter in your bathroom.
What this means for you
Basically, you get a heater that won’t short out while you’re taking a hot shower. But let’s be real: no seal lasts forever. Over the years, gaskets wear down. We pick materials that push that deadline as far back as possible, but it’s still a good idea to keep an eye on your housing. Just make sure water isn’t pooling near the terminals, and you’ll be set.
