Getting Your Bathroom Heat Just Right
Ever step out of a shower into a bathroom that feels like a walk-in freezer? It’s the worst. That’s where ceiling-mounted infrared heaters come in. Unlike those old-school heaters that try to warm up all the air in the room, these lamps beam heat directly onto you and the surfaces around you. It’s like stepping into a patch of sunlight on a cold day. But here’s the trick: you can’t just grab any lamp and hope for the best. You have to match the power to the size of your room. Finding the right wattage If you’re dealing with a tiny powder room—you know, those small spaces under 4m²—a single 400W to 600W short-wave lamp is plenty. It’ll get the job done without turning the room into a sauna. For bigger bathrooms (around 6m² to 10m²), you’ll need more muscle. Think multiple lamps or a beefier array, usually between 1200W and 2400W. Now, don’t overdo it. Putting a 2000W setup in a tiny closet-sized bathroom is just wasting electricity and making things uncomfortably hot. On the flip side, if you go too low in a big room, the lamp has to work overtime just to make you feel warm. That’s a great way to burn out the filament way sooner than it should. A few things to keep in mind Short-wave lamps are great because they’re instant. You flip a switch, and you feel the heat immediately. No waiting around. We use quartz glass for the bulbs because it lets the heat through without blocking it. But watch your ceiling height. If your ceilings are higher than 2.5 meters, a lot of that heat vanishes before it even hits your shoulders. In those cases, it’s actually better to get a more powerful lamp rather than just adding more units. You want that heat to actually reach you. Don’t blow a fuse One last thing—and this is important—check your wiring. A 2400W setup pulls a lot of power. If you’re installing this in an old house with ancient circuits, your breaker might not be happy. It’s a smart move to put high-wattage heaters on their own dedicated circuit. It saves you from the annoyance of the power cutting out right when you’re mid-shower. Get the wattage right for your space, and your heaters will last longer and your electric bill will stay sane.
