A functional and easily accessible ash pan collects all the burned out ash.

An additional air duct creates an air passage between the flame and the ceramic glass, ensuring cleaning for several hours.

The special combustion chamber made with Firex 600/700, a material based on vermiculite, results of the research and development conducted by Ravelli

It ensures ignition in a short time because it reaches very quickly temperatures > 750 °C. It is characterised by high energy efficiency and reliability over time much greater compared to a traditional resistance, being very resistant to thermal stresses and corrosion.

It detects the temperature of the flame in the combustion chamber and allows a more reliable and rapid control in the switching on, switching off and re-ignition hot automatic stages of the boiler.

New remote control that using radio frequencies allows to control the stove and regulate its functions from another room, optimising accessibility and comfort.

Self-cleaning precision casting brazier for better cleaning that maximizes energy efficiency.
