The 7 cm that make the difference: resistance-stone distance and perfect cornice

Many electric pizza ovens promise 500°C, but when it comes to cooking a real Neapolitan pizza, the result is often disappointing: a shallow, flat crust, or worse, burnt edges. The secret lies not only in the maximum temperature, but in a seemingly simple detail: the distance between the upper heating element and the surface of the stone.

In this article, we explain why those **7 cm** of the Diavola Pro v3.0 are no coincidence, but a design choice designed to achieve a high, honeycombed, fragrant, and perfectly cooked crust, without burning.

Why the distance between the heating element and the stone is crucial

Heat reaches the cooking chamber in different ways: conduction from the stone below, radiation from the heating element above, and convection of hot air. The distance between the upper heating element and the pizza determines how much radiant heat the crust receives and how much time it has to rise before browning.

• Distance too small (<6 cm): The crust receives too much heat too quickly → it burns on the outside while the inside remains raw.
• Distance too large (>9-10 cm): The crust receives too little radiation → it remains low, underdeveloped, and pale.
• Practical difference: Only with an optimal distance does the crust have time to expand and form the classic bubbles and cavities typical of Neapolitan pizza.

The 7 cm of the Diavola Pro v3.0: a precise technical choice

In the Diavola Pro v3.0, the distance between the upper heating element and the surface of the baking stone has been set to exactly **7 cm**. It's not a random number, but the result of tests and calculations to perfectly balance three elements:

• Powerful radiation from the upper heating element (1400 W)
• Sufficient time for the crust to develop naturally
• Protection from excessive burning on the edges

This distance allows the crust to rise properly for the first 40-50 seconds of cooking, forming a soft internal structure and a crispy, golden crust.

Comparison with other electric pizza ovens h2>

Most electric ovens on the market adopt different distances, often dictated by cost or design rather than performance:

• Low-cost ovens: often only 4-5 cm distance → burnt or crushed crust.
• Ovens with a high chamber: Distance greater than 9 cm → underdeveloped crust, "flat" pizza.
• Diavola Pro v3.0: 7 cm → optimal balance between development and browning.

This difference is especially noticeable with highly hydrated doughs (65-70%), where the crust needs space and time to expand properly.

How the 7 cm interacts with the rest of the system

The optimal distance doesn't work alone. In the Diavola Pro v3.0, it combines perfectly with:

• Two independent thermostats to regulate the heat above and below
• More powerful and extended upper heating element for even distribution
• Refractory stone with high thermal inertia
• Advanced insulation that maintains stable temperatures

The result is extremely uniform cooking: a crispy base, a well-developed crust, and perfectly cooked topping without burnt spots.

Concrete cooking results

With this configuration, the Diavola Pro v3.0 allows you to cook a Neapolitan pizza in approximately **90-120 seconds** at 430-480°C, achieving:

• Crust 2-4 cm high, well-aired and fragrant
• Dry and crispy base without being dura
• Even browning without the need to constantly rotate the pizza

The difference is particularly evident when comparing the same dough ball cooked in ovens with different distances.

Side considerations

The 7 cm between the heating element and the stone isn't just a technical detail: it's one of the factors that sets the Diavola Pro v3.0 apart from the crowd of electric pizza ovens. When looking for an oven capable of professional results at home, don't just rely on wattage or maximum temperature. Pay special attention (and above all) to details like this.

It is precisely thanks to design choices like this that the Diavola Pro v3.0 manages to combine high performance, ease of use, and consistent results, pizza after pizza.

FAQ

• What is the ideal distance between the heating element and the stone? Between 6.5 and 7.5 cm is considered optimal for Neapolitan pizza in home electric ovens.
• Does a greater distance improve the crust? No. Above 9 cm, the crust receives too little radiation and remains low.
• Can the distance be changed on a pizza oven? Generally, no; it is a fixed feature of the design.
• Is this distance only useful for Neapolitan pizza? It also helps a lot for pan pizza and Roman pizza, improving the development of the edges.
• Why do many ovens burn the crust? Mainly due to too little distance between the heating element and the pizza combined with poor heat management.
