Technical Deep-Dive: Matching Power to Space

We build our towel rail heaters around shortwave infrared halogen tubes because they throw heat straight where you need it—direct, line-of-sight warmth. The big call on any job? Matching the wattage to the bathroom. For a small wet room, around 1.5–2 m², you’re usually looking at 150–250 W per tube. Step up to a larger bathroom, 4–6 m², and you’ll typically need 300–500 W per tube. Voltage comes down to what your site already has. Retrofits often run on 110V. New builds? 220–240V. Here’s the thing: higher voltage means lower current for the same wattage. That keeps wiring runs cleaner and helps you avoid voltage drop over longer distances. And tube length? That’s not just about looks. It shapes the radiant footprint. A 300 mm tube gives you a focused heat pattern. A 600 mm tube spreads the warmth wider, which can mean you need fewer units to get the job done.
