Adequate fuel is required to power the tiled stove. Wood is a material, which regenerates in nature. It practically accumulates solar energy, and we can use it by smoking it in a tiled stove. To make this combustion as clean and energy-efficient as possible, it is important that only dry and clean wood goes to the combustion chamber of the furnace. When burned in a tiled stove, it must not contain more than 20 residual humidity percentage. When, for example, the combustion chamber of your furnace is filled 10 kg of wood with residual moisture 15 percentage, then we will put it in the oven with it 1,5 liter of water. In the combustion process, this water must warm up and evaporate, and in this way we will lose some of the energy. To keep this loss as low as possible, wood should be stored for a long time in a dry and well-ventilated room. As a general rule, we can take, that hardwood needs at least two years to dry, while from conifers at least a year and a half. In Germany, the annual growth of wood is estimated at approx.. 30 million cubic meters. This wood can be burned in tiled stoves, without increasing the C02 content in the air, because the gas released in this process re-binds the trees during their annual development cycle. But on the other hand, carbon dioxide released from fossil fuels during their combustion is transferred to the atmosphere..
So let's take this into account and burn only clean and dry wood in a tiled stove. The figure at the top shows the circulation C02, which is formed when burning wood.
