Introduction
So, here’s the idea behind this under-desk heater. We built it around a 2500W, 400V halogen quartz tube, packed into a tidy 300mm length. The whole point? To give you intense, focused heat exactly where you need it. It’s perfect for those tight spots where you just want to warm up a small area fast—without turning your whole room into a sauna.
The Inside Story
Let’s get into the guts of it. Running at 2500W on 400V gives you serious heat density in a small package. It’s a reliable setup. The power output is steady and predictable, so you get consistent heat, right when you need it. And the 300mm length? That keeps the heater slim enough to slide under desks or into enclosures, but it still covers the space you want to heat.
What It’s Made Of
Inside, you’ve got a halogen element housed in a quartz envelope. It runs hot, but it runs clean. And the quartz is tough. It handles those sudden temperature shifts without cracking or complaining. We went with the R7s connector, too. It’s a standard industrial choice for a reason. It’s easy to wire up, stays secure even with a bit of vibration, and it’s a straight swap for many existing fixtures.
Where It Shines
This is your go-to for quick, focused warmth right where you’re working. Think under-desk heating, warming up a small enclosure, or even drying something off locally. Now, a heads-up. 2500W is a lot of heat. So you’ll want to make sure the enclosure around it and the airflow are properly set up to handle that power and keep things cool.
