How to Pick the Right Wattage for Your Bathroom Heater
When you’re picking out an infrared heater for the bathroom, it’s tempting to just go for the most powerful one on the shelf. But here’s the thing: more power doesn’t always mean more comfort. It’s really just about matching the heat to the size of your room so you aren’t throwing money away on your electric bill. Getting the size right If you’ve got a tiny powder room—something under 4m²—a 250W to 400W shortwave lamp is plenty. These things kick in instantly. If you go overboard in a space that small, you’ll feel like you’re standing in an oven, and you might even trip your breaker. Not a great way to start the morning. For a medium-sized bathroom (around 4m² to 8m²), you’ll want to bump that up to 600W or 800W. And for the big master baths? You can either go with one heavy-hitting 1200W array or spread the warmth around with a few 800W lamps. Remember, infrared doesn’t actually heat the air; it heats whatever it touches. You just need enough coverage so that the spot where you’re actually standing feels cozy. Water and heat: The safety bit Since you’re putting this in a room full of steam and splashes, the IP rating is a big deal. We use sealed quartz glass and connectors that hate moisture to make sure nothing shorts out. Also, keep in mind that these lamps get seriously hot. Make sure your mounting bracket is built for the wattage you chose. You don’t want a fixture warping because the heat was too much for the metal to handle. Speed vs. Power Higher wattage means you hit that “perfect” temperature faster. But there’s a catch: the initial power surge. If you hook up three 1000W lamps to an old circuit, you’re asking for trouble with your wiring. A better way to do it is a staged power-on sequence. It keeps the load steady, saves your wires, and actually helps the lamps last longer. Just look at your room size and pick the wattage that fits. Anything more is just wasting electricity.
