Natural convection and radiant heating

In its standard configuration, WTX 70 Front distributes heat through a combination of natural convection and radiation, without requiring a fan.

This provides quiet operation and gradual heat distribution into the room.

Optional forced ventilation

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

Compatible control units are also available to manage the ventilation system.

Thermofix® firebox

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

Sliding door and easy glass cleaning

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

For easier cleaning, the glass can tilt by approximately 40 degrees, providing convenient access to its internal surface.

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, allowing more precise control of the burning process.

External combustion air

Combustion air can be supplied directly from outside the building when the installation is correctly designed.
