Getting Your Bathroom Heat Right (Without Burning the House Down)
When you’re picking out an infrared heater for the bathroom, your first instinct might be to just grab the one with the biggest number on the box. Don’t do that. It’s not about raw power; it’s about finding the right balance for your space and making sure the thing can actually handle a bit of splashing. The wattage trap I’ve seen too many people put 800W lamps in tiny powder rooms. It’s a waste. When you overkill a small room, the heater just kicks on and off constantly. That’s a great way to fry your relays and hike up your electric bill for no reason. If your bathroom is under 5 square meters, a 250W to 400W shortwave lamp is usually plenty. You’ll feel the warmth almost immediately. Now, if you’ve got a massive master bath, you’ll probably need a 600W to 1000W setup to keep that cozy feeling going. Dealing with water Since this is a bathroom, we have to talk about the IPX5 rating. In plain English? It means the heater is built to handle water jets hitting it from any direction. We seal the electrical junctions and use tempered glass to keep moisture away from the tungsten filament. Because if a single drop of water hits that filament? Pop. It’s gone. Even with a waterproof unit, just use some common sense—don’t mount your wiring right where the shower spray hits. Heat vs. Comfort The cool thing about shortwave infrared is that it heats you, not the air. You don’t have to wait twenty minutes for the room to warm up; you feel it the second you flip the switch. But be careful. If you put a 1000W lamp in a room with low ceilings, it can feel oppressive. Like you’re standing too close to a campfire. My advice? Try a tiered approach. Use lower power just to keep the chill away, and crank it up when you need that instant blast of heat. Just double-check that your wiring and circuit breakers can handle the load so you aren’t staring at a dark room every time you turn the heat on.
