Sigma Uni boiler is an automatic and extremely comfortable to operate boiler with a gutter burner adapted to the combustion of eco-pea. It has the highest quality materials used in the production of the burner, which guarantee its long-term operation. Special construction of the exchanger ensures optimal fuel combustion conditions, high efficiency and low emission of pollutants. The boiler has an intuitive and user-friendly controller with a color touch display with an adjustable angle of position.

Sigma Uni meet the energy and emission requirements of class 5 of the PN EN 303-5:2012 standard.
