It is called convection when heat is transmitted and creates natural air circulation in any room.
Rotating cover that allows the passage of air/smoke through a pipe to be opened/closed
A device used to divert the direction of the smoke flow before leaving the duct
Double Combustion
Technology whereby the gas from the firewood’s initial combustion is burned again. It provides greater efficiency and life for your firewood with lower consumption.
Double sided
These are fireplaces or wood burning stoves that have glass on the front and back of the fireplace in order to see the fire and get heat from both sides.
Channelling of air through ducts
Easy Fire Control
Fire control system that can regulate the optimal combustion and cleaning of the firewood appliance with one simple remote control device.

Surface treatment of the wood burning cook stoves with a high-quality enamel. Makes cleaning easy with as little as a damp cloth.
Ecodesign 2022
A European regulation (compliance with which is mandatory starting in 2022) that will require greater energy efficiency in all products and lower emissions of CO, OGC, NOx and other types of hitherto uncontrolled pollutant gases.

A European certification related to energy consumption. It grades the product based on strict sustainable criteria defined at European level and ensures that the purchased product meets the maximum sustainability requirements

Energy efficiency
This consists in the efficient use of energy. We refer to an efficient wood burning appliance when it consumes less energy than the average energy required to make it work.
Eolo System
High pressure ventilation system with centrifugal turbines and speed regulator (switchboard) to allow different rooms of the home to be heated through ducts.
External Air Inlet
Connectible system that takes air from outside the house for combustion. Suitable for low consumption housing.
Extra Clean Glass
Novel air intake system on the glass to keep it clean for longer.

An instrument or apparatus with rotating blades that drives or removes air.

Flamme Verte
Flamme Verte is a quality label for wood burning appliances in France. To obtain the Flamme Verte label, the energy and environmental performance of each device is controlled in laboratories, accredited against ISO / IEC 17025 and notified by the European Commission, whose tests give access to the CE certification.
Flow Driving
Hot air bypass system with selectable outlet. It allows for longer ducts and makes it possible to close the air outlet. Includes a turbine control unit.
