Tefal Thermo-Signal Technology
What is Tefal Thermo-Signal?
Did you know that preheating your pan is the key to perfect cooking? Much like pre-heating your oven when baking, preheating prepares the pan to produce ideal cooking results.
Discover Tefal's exclusive Thermo-Signal technology, a unique heat indicator built into our cookware that takes the guesswork out of perfect cooking. This proves particularly valuable when preparing delicate proteins like fish or searing meats.
Built right into the non-stick coating of the pan, Tefal's unique Thermo-Signal® heat indicator tells you when your pan has reached the optimum temperature to seal in the flavor of your food.
How to Use the Thermo-Signal

Place the Pan on the Heat
Set your Tefal non-stick pan on the stove and turn on the heat to medium or medium-high.

Wait for Thermo-Signal to turn solid red
As the pan heats, the pattern inside the red spot will slowly fade. When it turns solid red, your pan has reached the ideal cooking temperature.

Start cooking
Now that your pan is ready, add your ingredients and start cooking. If needed, you can lower the heat to keep the temperature steady and ensure even cooking.
Why use Thermo-Signal?
By clearly showing when your pan is properly preheated, Thermo-Spot helps unlock better cooking performance in several key ways:

Seals in flavour
Cooking at the right temperature helps quickly sear ingredients like meat, poultry or fish, forming a golden crust that locks in natural juices and intensifies flavour. The Thermo-Signal ensures you start at just the right moment for maximum taste.

Better non-stick performance
Non-stick coating is most effective when pre-heated. When the Thermo-Signal turns solid red, it means the surface has reached the optimal temperature for cooking.

Reliable results
With Thermo-Signal, you no longer need to guess if your pan is hot enough. This consistency leads to more predictable, repeatable cooking results.

Extends the life of your pan
The Thermo-Signal not only makes cooking smoother but also preserves the life of the non-stick coating by preventing premature wear from overheating.
Frequently Asked Questions
Do all Tefal pans have Thermo‑Signal?
No. Thermo‑Signal is featured on almost all non-stick cookware ranges but may not be included in uncoated stainless steel models. Always check the product details or packaging.
Can I use oil or butter before the Thermo‑Signal turns red?
For best results, preheat the pan first, wait for the Thermo‑Signal to turn solid red, then add oil or butter.
Can Thermo‑Signal wear out or stop working?
Thermo‑Signal is built into the non-stick coating and designed to last. With proper use and care (avoiding metal utensils and overheating), it will remain functional for the life of the pan.
