Introduction
We built this bedroom heater around a high-output halogen quartz tube. The whole idea? To give you fast, focused radiant heat—right where you need it. If your system is set up for an R7s connector and a 400V supply, this drops right in. No fuss. Just a straight replacement that gets the job done without overthinking the install.
The Nitty-Gritty
Let’s talk numbers, but the friendly kind. It runs on 400V, which keeps the current lower than a 230V option. That means you can use thinner wiring and not worry as much about voltage drop over longer runs. At 2500W, it packs serious heat density. Warm-up is quick, and the radiant field is strong. The tube is 300mm long, so the heat stays focused—perfect when space is tight and you can’t afford to waste a single inch.
What It’s Made Of
Inside the quartz envelope, the halogen cycle helps keep the filament temperature steady. That’s the kind of detail that translates to consistent output and a longer life than you’d get from a standard incandescent element. And the quartz body? It handles high heat without flinching and stands up to sudden temperature changes. The R7s connector is the kind of small win that makes a big difference. It’s a standard bi-pin setup that snaps in fast and carries the current it needs—no extra hardware, no headaches.
How It Feels in the Real World
In a bedroom, this heater is all about immediacy. You get that warm, radiant heat almost right away. The footprint is small, so it fits neatly into tight spots, and swapping it in is quick—especially with that R7s connection. A heads-up, though: 2500W at 400V means you’ll want a control circuit that’s properly rated, and you’ll need to plan for enough ventilation. Set up the thermal side of things from the start, and this heater just keeps running—steady, cycle after cycle.
