Sigma

Sigma is a boiler that is very convenient in use, is equipped with retort burner and is intended for combustion of eco pea coal. The highest quality of materials used for manufacturing of the burner ensure its long-term operation, while suitable design of the heat exchanger ensures optimum fuel combustion conditions, high efficiency and low pollutant emissions. Intuitive and user-friendly controller with colour touch display, with adjustable angle of inclination allows simple programming of the equipment and is responsible for control of system’s operation. Boiler meets the power-emission requirements of class 5 acc. to  PN EN 303-5:2012.

** Boiler in DiR version with additional grate for manual combustion - DOES NOT MEET THE CO-FINANCING REQUIREMENTS. Ordering DiR boiler please mark DiR on the order - deflector and grate
