Sunroom heater

We built this sunroom heater around a high-output halogen infrared tube for one simple reason: you need heat that shows up instantly, right where you need it. Glass rooms get chilly fast, and temperatures swing all over the place. This heater cuts through that chaos and wraps you in comfort. Here’s the power setup: a 400V, 2500W tube that’s just 300mm long. That’s a lot of heat packed into a small space. Running at 400V keeps the current lower, so the wiring stays neat and the conductors don’t need to be bulky. The 300mm length? It was a conscious choice. Short enough to slip into tight fixtures, but long enough to spread warmth evenly—no hot spots, just steady, even heat. Inside, the halogen element sits in a quartz envelope. That combo keeps the filament stable and the output consistent, so you don’t get the quick burnout you see with standard bulbs. Quartz also handles thermal shock, so rapid on-off cycling won’t crack the tube. And the R7s connector? It’s a quick-lock, double-ended pin setup that carries the high current safely. If you already have R7s sockets, this drops right in—no rewiring, no custom brackets. Just plug and go. In a sunroom, the heat arrives immediately as infrared warmth. It hits people and surfaces directly, so you feel cozy even when the glass is ice-cold. The unit is tough enough to shrug off weather and vibration. But with that kind of power, you do need solid thermal management in the fixture and a clear plan for ventilation to keep ambient temps in check.
