Why we put our bathroom heaters through the “steam torture” test
Let’s be honest: bathrooms are a nightmare for electronics. You’ve got thick steam, sudden temperature spikes from a hot shower, and humidity that basically hangs in the air like a wet blanket. If a seal slips or a material wears down, the heater doesn’t just stop working—it becomes a safety risk. We don’t like guessing when it comes to that. So, we use damp-heat aging tests to break our units on purpose, long before they ever end up in your ceiling.
The battle against moisture
Here is the thing about infrared heaters. The emitters get incredibly hot, but the housing and the wiring are sitting right in the middle of all that vapor. Water finds a way. It sneaks into the tiniest gaps in the chassis. Once it’s inside, it starts eating away at the terminals and ruining the insulation. To stop this, we throw every batch into a chamber with 95% humidity and crank up the heat. It’s basically a time machine that fast-forwards years of wear and tear into a few days. We’re looking for “creepage”—that’s when electricity decides to take a shortcut across a damp surface—and any sign of rust on the contact points.
Finding the sweet spot
It’s a bit of a balancing act. You can’t just seal a unit airtight. If you do, the internal electronics will overheat and fry themselves. But if you leave it too open? The humidity gets in and kills the lamp. It’s a tug-of-war between airflow and protection. Our aging tests are how we figure out exactly where that middle ground is.
Why this actually matters for you
When you’re wiring these into a home, the last thing you want is a unit that shorts out six months later because of a few steamy showers. By forcing the hardware to take a beating in our labs, we make sure the gaskets actually hold and the coatings don’t just peel off. It’s the only way we can be sure the heater will actually do its job the moment you flip the switch.
