When we design these commercial patio heaters, we have one clear goal in mind: pack a ton of warmth into a small outdoor space. For restaurants, that means relying on a high-output halogen quartz tube—the real workhorse of the whole setup. Power and the nitty-gritty These heaters are built to handle busy nights, running on either 230V or 400V. Take that 2500W element on a 400V line—it only pulls 6.25A. That keeps the wiring manageable, even for long runs across a big patio. And the 300mm tube? It focuses all that heat into a tight zone, so you get serious warmth per square foot without needing a bulky unit. Why the parts work so well The quartz envelope is tough. It handles the shock of turning on and off quickly, and it laughs in the face of rain and wind, unlike regular glass. Inside, the halogen gas lets the filament run hotter without wearing out fast, which means more of that toasty infrared energy gets pushed out. And the R7s base? It’s the standard for a reason. It’s a simple, double-ended connector that makes swapping out the tube a snap. Just drop it into the reflector, lock it in, and it stays put—even with all the hustle and bustle. What it’s like in the real world In a restaurant, you need heat that kicks in instantly and travels. This setup delivers that immediate, comforting warmth. But here’s the thing: that concentrated heat also warms the area right around the heater. So you’ll want to plan your mounting height and make sure there’s enough airflow around the unit. The heat does its job beautifully, but the enclosure still needs to breathe to stay in top shape.
