Keeping Your Bathroom Infrared Heaters Safe (and Dry)
Putting infrared lamps in a bathroom is a bit of a gamble if you aren’t careful. You’ve got steam everywhere and water splashing all over the place. The last thing you want is for someone to touch a wet wall and get a shock because of a ground fault. To make sure these things are actually safe, we focus on two things: the housing and how we seal the connections. Dealing with the Damp Here’s the thing: water vapor finds every single gap. It’s relentless. To stop it, we use high-temp silicone gaskets and IP-rated enclosures. This keeps the moisture away from the live parts. We also make sure the lamp holders are made from reinforced ceramics or heat-resistant polymers. Why? Because if the insulator cracks from the constant heating and cooling, the humidity will sneak in and create a path straight to the chassis. We don’t guess on this. We put the insulation through a 2kV dielectric test for a full minute. If there’s even a tiny bit of leakage, it doesn’t pass. The Reality of Wiring You absolutely have to wire these into a GFCI circuit. Period. Even with the best insulation in the world, things happen. A lamp filament might burn out and crack the quartz glass. In a steamy bathroom, that’s a recipe for trouble. That’s why we run a dedicated earth ground wire directly to the metal reflector. If something does go wrong and the insulation fails, the breaker trips instantly. It’s much better to have the power cut off than to have the whole fixture become electrified. The Balancing Act Now, there’s a catch. If you seal the enclosure too tight to keep the water out, you trap the heat inside. If that happens, your internal wiring starts to cook. Over time, the insulation gets brittle and just… snaps. It’s a bit of a trade-off. You need that IP rating for safety, but you still need enough ventilation so the wires can breathe. To help with this, we use PTFE-coated wiring. It handles the heat way better than the standard PVC stuff and doesn’t care about the moisture.
