Engineering the Sunroom Heater: High-Density Infrared Output for Targeted Space Heating
We built this sunroom heater to do one thing really, really well: deliver direct, radiant warmth right where you need it. No heating the whole room, no wasted energy. Just pure, line-of-sight heat that hits its mark.
Here’s what makes it work
The heart of this thing is a 300mm tube, packing 2500W of power and running on a 400V supply. That combo pushes serious current through the filament, which is exactly what you need to generate intense infrared heat. And because it’s all packed into a compact 300mm length, you get a huge amount of heat concentrated in a small space. Perfect for spot heating in a sunroom. But with that kind of power, you’ve got to make sure your wiring and thermal setup are ready for it. No cutting corners here.
The design that keeps it reliable
The tube uses a halogen cycle to keep the filament intact, even when things get seriously hot. That means it lasts longer, even under constant use. The quartz envelope is coated to filter out visible light and really lean into the long-wave infrared—the kind that feels most comfortable on your skin. And the R7s connector? It’s a simple, bi-pin design that makes installation a breeze. No tools needed, just a quick, secure connection. If you’re swapping out an old fixture, it’s an easy drop-in.
What it feels like in your sunroom
Imagine sitting in your sunroom and feeling warmth spread across you in seconds. No noise. No drafts. Just immediate, quiet comfort. That’s what this heater delivers. It turns on instantly, and because the heat is directional, you can aim it right where you sit. Now, there is one thing to keep in mind. This is high-intensity heat, so you need to make sure the spot you mount it—and everything around it—can handle that radiant energy without getting too hot. Plan accordingly, and you’ll be golden.
