Biomass stoves are currently the best option to heat our House when this does not require the power of a boiler or central heating in winter. Biomass is renewable organic matter, both of animal origin such as vegetable, including materials from their natural or artificial, transformation that is intended to generate energy. For these characteristics, they are greener than fossil fuels. Biomass stoves based on traditional life charcoal stoves, but applying more advanced technology, which is more comfortable to use and is optimized combustion. Some of them offer a great power, being especially indicated for large spaces, and others are ideal for domestic power. There are two main types of biomass stoves: the ones that work with pellets (most modern biomass fuel) and those that used firewood. The use of biomass stoves has several advantages, such as receive grants, its CO2 emissions are virtually nil, it is a renewable and inexhaustible, fuel in addition to cheap and some models have a design that allows you to take advantage of them for cooking. Biomass is solar energy converted by vegetation in organic matter; We can recover it that energy by combustion directly or transforming organic matter into other fuels. Contrary to the energies drawn from the tanatomasa (coal, oil), energy derived from biomass is renewable indefinitely.
