Tekla CLASSICO Boiler

The Tekla CLASSICO is a solid fuel boiler designed for wood chunks and hard coal. Thanks to its modern combustion chamber, the boiler meets the requirements of class 5 and Eco-design. The combustion efficiency ranges from 89.5% to 90.9%. The boiler operates effectively with natural flue draft, eliminating the need for an additional controller. It can work in both open and closed systems. The moisture content of the wood should not exceed 20%.
