The pellet boiler is a long-term sustainable heating method because wood pellets are a renewable natural energy that will still be available to future generations, unlike oil, gas or uranium.
More wood is planted than cut in European forests. Therefore pellets, "energy concentrates from solar energy" made of wood waste, have revolutionized heating in a sustainable way.
As the trees grow, they fix exactly the amount of CO2 they then release during combustion. This combustion does not release more CO2 than the natural degradation of wood in our forests. As long as the surface area of our forests does not decrease, the cycle is positive. This is the case in Europe and most of the world, where the surface area of forests increases year after year, even with a strong development of wood energy.
Burning wood in a pellet boiler is therefore one of the best alternatives to fuel/gas and electricity to ensure the energy transition and protect the climate. Wood pellet is a CO2-neutral fuel!
