From the 21 to the 25th of February the next edition of Progetto Fuoco will take place, and at Carbel we’re finalising the last details in order to participate again.
At Carbel, we are very keen to be able to participate at the only global event for the wood-fired heating industry: last year 754 companies including 322 from 38 countries outside Italy participated, besides having 70,317 visitors, including 14,540 foreign visitors from 69 different countries.

The use of renewable sources of energy is a positive gesture for the planet. In addition to being a renewable energy source, firewood does not contribute to the greenhouse effect when burnt. Nevertheless, not all kinds of firewood have the same heating qualities. We can distinguish between two main types of wood:
Coming from slow-growth trees such as oak, beech, ash, cherry, maple, chestnut, olive, elm, etc., this wood is slow-burning and offers high heating characteristics. Such wood is ideal for keeping the fire going over time, burning with a clear and continuous flame.
Coming from trees from the conifer family, such as fir, cedar, birch, alder, etc. Ignite rapidly and can be used to light or relight a fire. It is better to avoid the use of resinous woods such as firs, pines, etc., as they contain resins that cause smoke and blacken fireplace and wood stove glazing.
Use larger pieces of firewood for slower burning, when less heat is needed, or for maintaining the fire overnight. Always load large pieces after the fire has been burning strongly with smaller pieces, when the unit is already at a high temperature. Smaller pieces of firewood should be used to achieve a more strongly burning fire. Load them after starting the fire for a faster response, when more heat output is desired.
The lower the moisture content, the greater is the energy efficiency.
Good heat output and energy efficiency is closely related to the moisture level of the firewood. It is very important that the firewood to be used has been dried for two to three years and stored in a well-ventilated place. Recommended maximum moisture level – 21%.
How to recognize dry firewood
- Cracks can be seen on the surface of the trunk or branch
- The bark easily comes off
- A dry sound is heard when striking the wood
All our models are designed and manufactured to provide optimum performance. Nevertheless, operation and performance will depend to a great extent on how the units are installed. (más…)
