Fixing the “Hot Top, Cold Bottom” Problem in Bakery Ovens

If you’ve ever worked with a multi-deck oven, you know the frustration. The top deck is scorching, the bottom deck is barely keeping up, and you’re stuck rotating trays like a madman just to get an even bake. It’s a headache. We decided to stop fighting the air and change how the heat actually gets to the bread. Instead of relying on fans to push hot air around, we use independent Nichrome quartz infrared tubes. Here’s the thing about air. Standard convection is slow. It creates these annoying “cold spots” where your dough just sits there. By switching to quartz infrared lamps in every deck, we move to radiant heating. Think of it like the sun. The energy hits the dough directly. No waiting for the air to warm up. Just instant heat. We coil Nichrome wire inside a high-purity quartz sleeve and give each deck its own PID controller. This is the secret sauce. Since the oven floor usually leaks heat, you can simply crank up the wattage on the bottom deck to balance things out. Why quartz? Because everything else breaks. When you’re hitting 500°C, cheap glass will shatter the second it feels a temperature swing. Quartz handles that thermal shock without flinching. Pair that with the Nichrome element—which keeps a steady electrical resistance—and your heat won’t drift or dip just as you’re hitting peak temp. One quick tip: watch your wiring. In those big industrial setups, voltage can drop over long runs. If the voltage dips, your heat drops. Use heavy-gauge wiring. It’s a small detail, but it makes a huge difference in how the tubes actually perform. The trade-off (because nothing is perfect). These tubes are great for a quick setup. They heat up in seconds, so you aren’t standing around waiting for the oven to preheat. It saves a ton of time in the morning. But, you have to be careful. Quartz is brittle. If a rack vibrates too much or someone bumps a tube while loading a tray, it’s going to shatter. You’ll want to install some guards or just make sure your tolerances are tight. Also, since these things put out a lot of concentrated heat, don’t skimp on the outer shell insulation. You don’t want the outside of the oven becoming a burn hazard for your staff.
