Keeping Your Infrared Heaters Safe in Wet Spots
Let’s be honest: putting a heater in a bathroom or out in the garden is a bit like playing with fire—or in this case, electricity and water. It’s a risky mix. If steam or rain finds its way into the housing, it creates a shortcut for electricity to go exactly where it shouldn’t. That’s why we don’t mess around with our moisture barriers.
The Deal with IP65 and Keeping Water Out
You’ll see us talk about an “IP65 rating.” In plain English? It means the unit is tight enough to keep out dust and can handle a decent spray of water without breaking a sweat. We use silicone gaskets and sealed cable glands to make sure moisture never even sees the internal wiring. But for those steamy bathrooms, we go a step further. We wrap the internal leads in high-temperature fluoropolymer or silicone sleeving. Why? Because regular insulation gets brittle and gross when it’s constantly blasted with steam. This stuff stays tough, keeping your insulation resistance high for years.
Grounding: Your Safety Net
Here is the thing: no seal is perfect forever. That’s why we build a dedicated earth bond right into the metal chassis. If a seal ever fails and a live wire touches the casing, the current hits that bond and trips your RCD (Residual Current Device) instantly. **Do yourself a favor and always wire these into a GFCI or RCD-protected circuit.**Relying on a plastic shell to keep you safe is a gamble you just shouldn’t take.
Heat, Cold, and the “Breathing” Problem
Infrared lamps get hot. Really hot. When the heater kicks on and off, the materials expand and shrink. It’s almost like the unit is “breathing,” and that action can actually suck moist air through tiny, microscopic gaps in the seals. To fight this, we use spring-loaded gaskets. They push back and keep the seal tight, even as the temperature swings. Still, physics always wins eventually. Every gasket wears down over time. Just make it a habit to check your seals every two years. A quick look now prevents a big headache later.
