The three most common sources of energy to power ovens are: wood, gas and electricity.

The wood-fired oven is made from refractory material and is easily recognisable due to its internal vault shape. The fire lit inside the cooking chamber is not far from food and heats the vault which exchanges its heat – via radiation – with the bedplate.

The evolution of the wood-fired oven is embodied by the combustion system of gas ovens. In gas ovens, heat is produced by a burner which is positioned under the bedplate, this spreads heat within the chamber via radiation and convection.

In external combustion systems, heat transfer takes place via a heat exchanger which heats the air flow that is conveyed inside the cooking area.

The electric oven produces the necessary heat for cooking thanks to a series of resistors located in the  cooking chamber.

The resistor is an easily shaped metal body that heats electrically via the Joule effect.
