Introduction
Here’s the thing about greenhouse heaters—they have one job, and it’s a pretty specific one. We need to keep your plants warm without turning the whole space into a sauna. So we built these heaters to do just that. They use shortwave infrared heat that goes straight to the plants. The heart of it all? Halogen infrared tubes. They’re tough enough to handle the constant swings in moisture and temperature inside a greenhouse, day after day, without giving up on you.
The Tech, Without the Fluff
Most of these units run at 2500W and 400V. Why that specific setup? Because higher voltage means less current for the same power. And that makes a real difference. It keeps your cables thinner and cuts down on voltage drop across long runs—a huge relief when you’re wiring a massive greenhouse. The tube itself is around 300mm long, so it’s nice and compact. That means you can mount it close to your plants without needing some giant, clunky reflector hanging off it.
What It’s Made Of
The tube is quartz, and there’s a good reason for that. It handles sudden temperature changes like a champ. Inside, halogen gas keeps the filament stable, which means the heat output stays steady over the life of the lamp. And there’s an internal reflective coating that pushes more energy forward. So you’re not wasting heat—you’re aiming it right where you need it. The connector is an R7s, a simple two-pin base. It makes wiring a breeze and swapping out a unit a simple, drop-in job.
Why It Works for You
Inside a greenhouse, infrared heat goes straight for the leaves and stems. That means you can keep your plants at the right temperature while keeping the air a bit cooler. The payoff? Less condensation, which can really help lower disease pressure. Now, there’s one thing to keep in mind. These heaters pack a lot of heat, so they run hot. You’ll need to plan for proper mounting clearance and make sure there’s some local ventilation. But if you size the fixture right and wire it up as intended, you get steady, predictable heat with hardly any fuss or maintenance.
