Natural convection and radiant heating

In its standard N18 configuration, WTX 80 Front distributes heat by natural convection and radiation, without requiring forced ventilation.

Optional forced ventilation

A dedicated Palazzetti WTX radial fan kit can be added when faster hot-air distribution is required.

ET4W smart ventilation control

The optional ET4W control unit can manage the ventilation system and supports Wi-Fi control through the Palazzetti App.

Thermofix® firebox

The combustion chamber uses Thermofix® refractory material, developed for the high temperatures generated by wood combustion.

Sliding door and easier glass cleaning

The fireplace features a robust sliding-door mechanism designed for smooth operation.

The glass can tilt approximately 40 degrees to simplify access to its internal surface during cleaning.

Flue-gas bypass valve

When the door is opened, the flue-gas bypass valve helps direct smoke towards the chimney during wood loading.

Primary and secondary air control

Combustion can be managed through separate primary and secondary air regulation.
