Under desk heater

Introduction

We built this under-desk heater with one idea in mind: give you heat that hits right where you need it, without taking over the whole room. It runs on a 400V halogen infrared lamp, and the heart of it is a 300mm quartz tube that cranks out 2500W. Perfect for those tight spots where you need serious heat, fast, but you don’t want to tear your workstation apart to get it.

The Nitty-Gritty

Here’s the thing about running it at 400V—it lets us pack 2500W into a short 300mm tube. That means you get a lot of heat in a very small footprint. And it’s not just about power; it’s smart power. That voltage is a natural fit for industrial setups, because it keeps the current lower for the same output. Less strain on the wiring. Less stress on the connections. The 300mm length hits a sweet spot. It’s short enough to slide under desks and consoles, but long enough to cover a real, usable heating zone.
