Introduction
We built this office heater around a high-voltage halogen quartz tube—because when you need warmth in a commercial space, you want it focused, fast, and dependable. It’s the kind of heat that shows up the moment you need it, without a lot of fuss. Installation is quick, the output stays steady, and the performance doesn’t get wobbly when space is tight and timing matters.
What’s really going on under the hood
It runs on 400V, which lets us pack a lot of wattage into a compact tube—without overloading the branch circuit. The tube is about 300mm long, so you get a dense heating footprint without giving up cabinet space. The payoff? High heat density. You feel it in how fast it warms up. When occupancy shifts, the heater responds immediately—no waiting around.
Materials and design choices that matter
Inside the quartz envelope, halogen gas helps keep the filament temperature stable. That’s the quiet work that keeps output consistent over the life of the lamp. The quartz body handles thermal shock well, so powering on and off over and over doesn’t create cracks. And the R7s connector? Replacement is straightforward—slide the tube in and lock it. No tools. Just a solid connection and dependable alignment, even if the mounting spot sees a lot of vibration.
Where it shines—and what to keep in mind
In office buildings, this heater is perfect for localized zones: lobbies, entryways, conference rooms. It takes pressure off the central HVAC and delivers radiant heat straight to where people actually are. You feel the warmth almost instantly—no waiting for ducted air to travel. Just one thing to note: with 400V and 2500W of density, it needs adequate ventilation and a properly rated cooling path. We designed it for continuous duty, and it drops right in as a replacement on standard R7s fixtures.
