Dog House Heater: 400V Halogen Quartz Tube with R7s Connector
We built this dog house heater to be a straightforward, industrial heat source—one that fits right in and just gets the job done, even in those cramped spots. It’s a 400V, 2500W halogen quartz tube, 300mm long, and it’s wired to run hard and keep running.
Power, Voltage, and Dimensions
Here’s the thing: the 400V rating is for plant lines where you want one tube, not a bunch of lower-voltage ones wired in series. Simpler, cleaner. At 2500W packed into 300mm, the heat density is serious. That means it hits the setpoint fast. Really fast. But with that kind of intensity, you’ve got to manage the heat around it—the dog house structure and any nearby wiring need breathing room. Keep the mounting clearances snug, sure, but make sure air can move around the housing. A little planning goes a long way.
Material and Design: Halogen, Coating, and R7s
The halogen fill keeps the element steady, even when you’re cycling it on and off again and again. No fuss. The quartz envelope handles the shock of going from cold to blazing hot without softening or giving up. And that coating? It’s a tough layer that stands up to grime and weather, so the heat stays consistent. Then there’s the R7s connector. It’s a solid, two-pin setup that gives you a secure mechanical and electrical fit. It’s the standard for a reason: it installs quickly and stays put, even when things are vibrating.
Application and Benefits
If you need a compact heater that can take the heat and keep working, this is it. It drops right in as a replacement for existing dog house heaters, and it’s the kind of choice that makes engineers breathe a little easier. Predictable output. Simple wiring. You’ll feel that quick warm-up, the steady run, and the easy maintenance. Just plan for proper cooling and follow good high-voltage insulation practices when you install it.
