B 31 GB

The BIGAVAC ECO B 31 GB is a wood gasification boiler with a nominal heat output of 31 kW, 91% thermal efficiency and an A+ energy rating, designed for central heating systems with higher energy demands, particularly larger homes and buildings requiring heating across multiple areas.

Its advanced gasification technology ensures controlled and efficient combustion, maximising the energy extracted from wood through a secondary combustion chamber lined with refractory ceramic materials. The combustion air regulation system and extraction fan contribute to a stable combustion process and consistent thermal performance.

The 140-litre loading chamber accommodates logs up to 50 cm in length, providing generous fuel capacity for heating systems with greater heat requirements. The electronic control unit allows precise temperature adjustment and monitoring of key operating parameters.

Built with a robust steel structure and equipped with thermal insulation. Combining power, efficiency and durability, it offers a reliable wood-fired central heating solution designed to meet demanding heating requirements.
