Side-by-side field observations from a working greenhouse: floor temperatures, root-zone temperatures, slab conduction, and what Reflect-O-Ray’s flattened tube profile did for plant response over seven seasons.
Two heaters can both be called “radiant” and behave nothing alike. Reflect-O-Ray’s low-mass aluminized spiral tubing changes five specific things about how a radiant tube system performs in a working building — and these are the engineering choices that make those changes possible.
Infrared is the warming part of sunlight — invisible light that travels through cold air without warming it, then sinks into solid surfaces and heats them directly. A Reflect-O-Ray tube heater puts out the same warming part of sunlight, with the visible glare and the UV stripped out.
Underfloor heating in a tall shop deposits moisture wherever surfaces sit below the dew point. After a decade that grime line is visible from across the room — and the LED retrofit didn’t cause it. It just stopped hiding it.
The pattern most producers actually saw — and why no amount of tuning was ever going to fix it.
Bird behavior is the most honest temperature sensor in your barn. When the chicks crowd the corners, they’re not telling you the corners are warm. They’re telling you something else entirely.
A plain-talk explainer. Same fuel. Same energy. Two completely different barns. The difference isn’t in the equipment specs — it’s in the physics of how heat is delivered.
Rust on the hinges. Stains on the door. Wet ceiling every cold morning. This is not a moisture problem — it is a temperature differential problem, and the fix is different than you think.
A thermostat measures air. It tells you nothing about your walls, your doors, or your equipment. Real data from two Western Canadian shops at −35°C shows exactly how different those numbers can be.
