How Many BTUs Do I Need
How Many BTUs Do I Need for a Commercial Griddle?
If your griddle struggles to keep up during service, it’s usually not the size — it’s the heat output.
This is a practical guide based on real commercial setups. Specifications vary by model, but the principles stay the same.
Griddle size tells you how much you can cook at once. BTU output determines whether the plate can actually handle it under pressure. If the heat isn’t there, the plate drops temperature as soon as you start loading it with food — and that’s where consistency starts to fall apart.
Why BTU Output Matters
BTU output affects heat-up time, but more importantly, it controls how well the plate recovers during service. You see it immediately with high-demand items like burgers and bacon — once cold product hits the plate, the temperature drops, and without enough output, it doesn’t come back quickly.
Most commercial gas griddles are built with roughly one burner for every 12 inches of cooking surface. That setup keeps heat consistent across the plate, even when it’s fully loaded.
Griddle Size vs Output — What It Means in Practice
| Griddle Width | Burners | Typical Output | Best For |
|---|---|---|---|
| 24″ | 2 | ~40,000 – 60,000 BTU | Breakfast menus, lighter service, smaller setups |
| 36″ | 3 | ~60,000 – 90,000 BTU | Food trucks, cafés, everyday commercial use |
| 48″ | 4 | ~80,000 – 120,000+ BTU | Busy kitchens, events, higher-volume cooking |
Don’t Oversize Without the Power
A larger plate gives you more space, but it also needs enough burner output to support it. If the output is too low for the plate size, it can struggle to recover once you’re cooking multiple items at once.
This is where higher-output units make a difference. Models like the Infernus 1200mm 5 burner gas griddle go beyond the standard layout, adding an extra burner across the plate to improve heat distribution and recovery during busy service.
With designs that maximise usable cooking area — up to 99.75% of the plate width — you’re not just getting a bigger griddle, you’re getting more effective working space without wasted edges.
It’s not just total BTU either. How that heat is spread across the plate has a direct impact on performance, especially when the griddle is fully loaded.
Which Setup Is Right?
For many kitchens and mobile setups, a 36 inch griddle offers the best balance between cooking space and usable output. It provides enough room for most menus without becoming difficult to manage in terms of gas supply, ventilation or footprint.
If burgers or high-volume items are central to your menu, it’s worth focusing on output as much as size. A well-balanced setup will keep up with demand far more reliably during busy periods.
