Stop Over-Powering Your Bathroom Heaters
When it comes to picking infrared lamps for a bathroom, most people think “bigger is better.” They go for the highest wattage they can find, thinking it’ll be warmer. But here’s the thing: that’s usually a mistake. If you throw too much power into a small space, you aren’t just wasting electricity. You’re actually burning out your filaments way faster than they should. It’s all about the balance between the heat and the size of the room. Finding the right fit If you’re dealing with a tiny powder room (under 4m²), keep it simple. A 250W to 400W short-wave lamp does the trick. These rooms are small, so the heat hits you almost instantly. No need to go overboard. For those medium-sized bathrooms (4m² to 8m²), you’ll want to bump that up to 600W or 800W to keep things cozy. But once you get into those big master baths (over 10m²), a single lamp just won’t cut it. You’ll end up with “cold spots” where you’re shivering in one corner while the other is roasting. Instead, try a few 400W units spread out in a grid. It keeps the heat even and doesn’t overload your circuit. The “Sauna” Problem High-wattage lamps feel great at first. That immediate punch of heat is amazing. But there’s a catch. In a tight space, the air temperature can spike way too fast. If your exhaust fan can’t keep up, you’ll end up in a stifling sauna that feels more uncomfortable than warm. You have to make sure your ventilation can actually handle the heat you’re pumping in. Work smarter, not harder If you want to get the most out of your energy bill, look at the emission angle. A lamp with a tight, focused beam puts the heat exactly where it belongs—on you—instead of trying to warm up the walls. When you pair the right wattage with a good reflector, you hit that perfect skin temperature without wasting power. Seriously, stop over-sizing your heaters. If you don’t match the wattage to the actual square footage, you’re basically just paying to heat your ceiling.
