Compact room heater

We built this little room heater around a high-density halogen quartz tube, so you get serious, focused heat—without taking up a ton of space. It’s the kind of tool you reach for when you need spot heating right next to a machine, or when you’re squeezing power into a tight enclosure where space is at a premium but performance can’t be compromised. Power, voltage, and size—kept simple. It runs on 400V and cranks out 2500W in a body that’s just 300mm long. That’s a lot of watt density packed into a small footprint, which means the temperature jumps fast without needing a heater that feels oversized. And because it’s high voltage, you get lower current for the same power—so your wiring can be leaner, and the connections in the field stay calmer. The short length also makes it easy to fit into narrow channels and compact guards. What’s inside—and why it stays steady. Inside, the halogen element lives in a quartz envelope, which helps the output stay consistent over time. The internal cycle keeps the filament running hot, so it resists the blackening that can quietly steal heat. A reflective coating then pushes more energy forward, giving you more usable heat where you aim it and less wasted side radiation. And the R7s connector? It’s a straight, two-pin setup that wires up quickly and holds its alignment, even when you’re working inside tight brackets. Where it shines in real life. Use this heater when you need heat that responds fast and repeats reliably—think small drying zones, pre-heat stations, or localized environmental control. It’s also a straightforward drop-in replacement for heaters that already use the R7s connection. One thing to keep in mind: that 2500W density is powerful, so it needs proper airflow or solid heat sinking. Plan your cooling and thermal management so nearby parts stay cool and protected.
