How to actually keep wet zones warm
Let’s be honest: locker rooms and spa areas are a nightmare to heat. You’ve got high humidity, drafty ventilation, and people who are shivering the second they step out of the shower. They don’t want to wait twenty minutes for the room to warm up. They want to feel warm now. That’s why we stop trying to heat the air and start heating the people. We use shortwave infrared (IR) for this. Think of it like the sun. Instead of blowing hot air around—which just disappears into the vents—shortwave IR sends heat straight to the skin. You flip a switch, and a freezing locker room feels cozy in seconds. Dealing with the splash zone Water and electricity don’t mix. In a spa, splashes are basically a guarantee. If you use a standard heater, it’s going to corrode or short out faster than you can blink. To stop that from happening, we stick to IPX4-rated gear. In plain English? The units are sealed tight. We use heavy-duty gaskets and sealed cable entries so that moisture stays on the outside and the wiring stays dry. It just works, and you don’t have to worry about it. The “punch” of shortwave heat There are different types of IR, but we go with shortwave because it hits harder. It has a higher energy density, meaning the element hits its peak temperature almost instantly. It’s an immediate thermal punch. In those open-air changing areas where the heat usually just vanishes, this is the only way to actually keep someone warm. Getting the install right Here is the catch: you can’t just slap these on a wall and hope for the best. Since shortwave heat is so intense, placement is everything. If you mount them too low, your guests are going to feel like they’re standing too close to a campfire. Too high, and the heat loses its edge before it reaches them. We spend a lot of time calculating the exact distance based on the wattage to make sure there are no “hot spots.” One more thing—your power needs to be rock solid. If your voltage drops, your heat drops. Just make sure your breakers can handle that initial surge when the lamps kick in. When it’s done right, it feels like a five-star hotel. No shivering, no waiting—just instant warmth.
