Greenhouse Electric Heater: Heat That Actually Reaches Your Plants
Here’s the thing about greenhouse heating: you don’t want to just warm the air. You want heat that gets down to the leaves, where it matters. That’s exactly why we built these electric heaters. We’re focused on one thing—delivering direct, controllable warmth straight to the plants. The result? Stable leaf-level temperatures, without forcing your ventilation system to work overtime.
The Power Behind the Warmth
Let’s get into the details, but keep it real. Each unit is a 2500W, 400V halogen infrared tube. That high voltage is a smart move—it drops the current while keeping the power strong. So you can run longer strings of heaters without wrestling with voltage drops or needing heavy-duty wiring. And the tube itself? Just 300mm long. That compact size is a lifesaver when you’re trying to fit fixtures in tight spaces around your crops. High wattage packed into a short tube means you get heat fast. And tight temperature control? That comes naturally.
Thoughtful Design, Down to the Details
We coated the quartz tube to push the output toward longer infrared wavelengths. This isn’t just for show. It helps the heat cut through the boundary layer and reach the plants, while keeping surface temps lower so you don’t scorch delicate foliage. Then there’s the R7s base. It’s a simple, direct bi-pin fit that slips right into standard greenhouse sockets. No fuss. It locks in place, stays aligned, and handles repeated relamping without any wobble. Just plug it in and go.
How It Works in Your Greenhouse
Out in the greenhouse, this setup shines. You get rapid response and even coverage across benches and hanging baskets. But here’s the honest part—packing 2500W into 300mm is powerful. That means your control strategy and cooling need to be just as thoughtful. We make sure these heaters are specced to run on properly rated circuits. That way, you get dependable performance, day after day, without the guesswork.
