OEM Electric Heater Factory Guide: How to Match Infrared Power to Your Room

We build OEM infrared heaters for industrial and commercial jobs, and there’s one question we hear constantly: How much power do you really need? It’s not a guess. It comes down to two things you can actually measure: how your room faces and how well it’s insulated.

Power, Voltage, and Size—What Actually Matters

Infrared heaters warm by radiation, so the heat output is directly tied to the electrical input. A 2500W unit gives you a strong, steady push of warmth. A 1500W unit gives you less. Voltage is about how you wire it. A 400V heater runs on three-phase power, which spreads the load across phases. That keeps the current per leg lower, cuts voltage drop on long runs, and lets you use smaller wiring. Then there’s tube length—usually 300mm or longer. It sets the surface area that radiates the heat. A shorter tube concentrates the heat. A longer tube spreads it out for broader coverage.
