Picking the Right Power for Your Bathroom Heater
When it comes to infrared bathroom heaters, more power isn’t always better. It’s tempting to just grab the biggest wattage you can find, but that’s usually a mistake. It’s really more about how much heat you actually need for the size of the room. If you put a monster lamp in a tiny bathroom, you’re just wasting electricity—and you might actually bake the fixture. Getting the heat right Here’s the thing about infrared: it doesn’t heat the air. It heats you. If you’re dealing with a small bathroom—say, under 4 square meters—a 250W to 400W lamp is plenty. You’ll stay warm and comfortable without feeling like you’re standing in an oven. For those huge master baths or commercial spaces, you’ll want 600W or 800W. But a pro tip? Instead of one massive, scorching lamp, try two smaller ones. We’ve seen too many people install one giant heater that forces you to stand in one exact spot to feel the warmth. Two 400W lamps spread the heat out. It feels more natural, and it keeps the bulbs from burning out too fast because they aren’t under so much stress. The battle with moisture Bathrooms are steamy. That’s why the seals on these things have to be tight. We use IP-rated housings to make sure moisture doesn’t touch the electrical parts. But there’s a catch. When you seal a unit tight to keep water out, you’re also trapping heat inside. If you shove a 1000W lamp into a small, sealed box, the socket can actually melt. It’s a mess. Just double-check that your housing is actually built to handle the wattage you’re plugging in. The trade-off Higher wattage means the heat hits you faster. Which sounds great, right? Especially in the dead of winter. But there’s a downside. If you put an 800W lamp in a tiny room, the thermostat will trip almost immediately. The heater will click on, get too hot, click off, and then repeat. That constant “on-off” hammering kills the relays. Match the power to the room size. Your heater will run smoother, last longer, and you won’t be jumping between freezing and sweating.
