How to pick the right wattage for your infrared towel rail
When you’re picking out an infrared lamp for your towel rail, your first instinct might be to just go for the most powerful one available. But here’s the thing: more power isn’t always better. It’s really all about how much space you’re trying to heat. If you overdo it, you’re just throwing money away on your electric bill. If you underdo it? You’re left with a damp towel on a chilly morning. Not a great way to start the day. Finding the sweet spot for your space If you’ve got a tiny bathroom—you know, those cozy little powder rooms under 4m²—you don’t need much. A small lamp (around 200W to 400W) does the trick. In a tight space, the heat bounces off the walls quickly, keeping everything warm without making the room feel like a sauna. But if your bathroom is on the larger side (6m² to 10m²), you’ll want to step up to 600W or 800W. Heat escapes faster in bigger rooms. If the wattage is too low, those infrared waves just vanish into the air before they can actually get into the fabric of your towel. You’ll end up with a towel that feels “sort of” warm, but is still stubbornly damp. Why infrared feels different The cool part about these heaters is that they use short-wave infrared. Most heaters just warm up the air, which then drifts away. These lamps are different. They target the towel and you directly. It’s a much more immediate kind of warmth. Plus, we use quartz glass for the envelopes, so the filament hits its peak temperature almost instantly. No more standing around waiting for an oil-filled rail to slowly wake up. You flip the switch, and it’s hot. Just like that. A few things to watch out for Now, a quick word of caution. While a high-wattage lamp packs a punch, it also puts more pressure on your home’s wiring. If you plug a 1000W lamp into a circuit meant for 300W, you’re asking for a tripped breaker—or worse, damaged insulation. It’s worth double-checking that your electrical setup can handle the load. And one last tip: keep an eye on where you place the rail. Higher power lamps have a shorter “throw” before they start to feel too intense. You don’t want to create a “hot spot” where it feels like you’re standing too close to a campfire. Position it carefully, and you’ll have that perfect, cozy glow.
