Biomass "Driven", Fogo Montanha solutions contribute for the sustainability
of our forest and our Planet. Find out here how we heat your home
in an efficient and comfortable way, while contributing to a “cleaner” world.




Wood is considered as stored solar energy and consists of the following components: water, sunlight and carbon dioxide. The amount of carbon dioxide released by wood (when burned) is actually the same it has extracted from the atmosphere as part of its natural cycle and that is then chemically absorbed by trees. Whether the wood decays in the forest or is burned is meaningless. The carbon dioxide output will always be the same – whether as part of its life cycle or when burned for heating purposes.

The carbon dioxide released during the combustion process is subsequently absorbed by the remaining trees, therefore initiating a natural cycle of carbon dioxide absorption, i.e. neutral carbon.

Wood combustion for heating purposes is an ecologically responsible option since in most European countries there has been a considerable increase in the use of firewood material from forest production, in an average estimate of 40% more than firewood consumption.


Firewood and wood pellets are today the most cost-efficient sources of fuel for household heating, which means that the investment in biomass heating equipment will pay off in very short time.

The following figure illustrates the differences in cost per kW between the various heating fuels available, taking the cost per kW of firewood as the reference point. The savings obtained when using biomass (firewood or pellets), rather than other forms of fuel for heating, are easily verifiable.




Forests are one of our main resources and one of Nature’s major components due to the critical role it plays in our planet. They are essential to promoting biodiversity, fighting against soil erosion, repairing water systems and contributing to the quality of air and water.

Forests occupy approximately 30% of the European territory which makes it critical to promoting an effective forest management that protects and leverages a relevant community resource while contributing to meeting the emission limits set forth under the Kyoto Protocol.

A healthy Forest Management includes the felling of selected trees and the replantation of new ones, as necessary.

When selecting firewood for your fire stove, you should be aware of certain details, such as density and humidity.

It is important to note that humidity dramatically reduces the heating power of any type of wood. The heating value of a type of wood with 50% of humidity is 2 times decreased. Wood used for combustion should not have a humidity level greater than 18%.

Softwood species (for example, Pine) usually burn faster due to its resin combustion components and offer less density than hardwood species. They prove to be very effective for lighting the fire.

Hardwood species (the remaining trees in the table, for example, Oak and Olive tree) produce more durable firewood during combustion due to their density.

Some trees, like the eucaliptus, produce firewood with a good heating value and a good density but, due to their chemical composition, at high temperatures may become far more corrosive to the equipment.

When choosing your type of firewood, take into consideration the trees existing more abundantly in your region. You will be contributing for a better forest management in your area and avoiding the transportation of firewood between different regions.
