Keeping Things Safe: Infrared Heaters in the Shower
Putting infrared lamps in a bathroom is a bit of a gamble if you don’t do it right. You’ve got steam everywhere and water splashing just about everything. In a spot like that, a basic heating element isn’t just a bad choice—it’s a liability. You need a setup where the electricity and the water never, ever meet.
Stopping the Leak
The real trouble starts where the lamp meets the housing. If moisture builds up on a standard quartz tube, it can actually start conducting electricity. That’s a disaster waiting to happen. To fix this, we use high-temp silicone seals or ceramic insulators at the ends of the lamps. Think of these as a wall that the current just can’t climb over. It keeps the power in the filament and away from the metal frame. But the seals are only half the battle. Water loves to sneak in through the wire entry points. We use IP65-rated glands and heat-shrink tubing with a glue lining. It’s a tight, physical seal that tells humidity to stay out of the electrical junctions.
The Safety Net
Now, even the best insulation can fail. That’s why you can’t just rely on the seals. You have to wire these units into a system with an RCD or GFCI. We also make sure the entire chassis is bonded to the earth ground. If something goes wrong inside and the insulation fails, the RCD kills the power instantly. It’s the difference between a tripped breaker and a metal casing that’s live to the touch.
The Balancing Act: Heat vs. Water
Here’s the tricky part. If you seal the unit too tight to keep the water out, you end up creating an oven. The heat gets trapped inside, and before you know it, your wiring insulation is fried. It’s a tough trade-off. Our fix? Breathable hydrophobic vents. They’re clever little things that let moisture vapor escape and equalize the pressure, but they stop liquid water from getting inside. You get a unit that’s safe from the shower spray without cooking its own guts.
