puukattiloiden

Puukattilat are wood-fired boilers used for heating buildings. They operate by burning wood, typically logs or wood chips, to generate heat that is then transferred to a water system. This heated water circulates through radiators or underfloor heating to warm the living space. Puukattilat are a renewable energy source, as wood is a sustainable fuel when harvested responsibly.

The design of a puukattila generally involves a combustion chamber where the wood is burned. The heat produced from this combustion is then transferred to a water jacket surrounding the chamber. From the water jacket, the hot water is pumped to the building's heating system. Modern puukattilat often incorporate advanced features such as automatic stokers, which can feed fuel more efficiently, and sophisticated control systems to optimize combustion and temperature.

There are different types of puukattilat, including gravity-fed systems and those with forced circulation. Gravity-fed systems rely on natural convection to move water, while forced circulation systems use pumps. The efficiency of a puukattila depends on its design, the quality of the fuel used, and how well it is maintained. Regular cleaning and proper operation are essential for optimal performance and longevity. Puukattilat can be a cost-effective heating solution, especially in areas where wood is readily available. However, they require more manual effort for fuel loading and ash removal compared to other heating systems.
