Baca is a low-temperature hot water boiler, which means it is not subject to registration with the Regional Office of Technical Inspection – this is a significant convenience for the investor, eliminating additional formalities during installation.
Manual Coal Boiler

Modern bottom-burning water boiler
The Stalmark Baca boiler is a manual coal-fired boiler designed for heating single-family homes with solid fuel – hard coal of the pea size grade. Thanks to the use of bottom-burning technology with a fuel gasification effect, the Baca boiler combines high energy efficiency with low fuel consumption and reduced exhaust emissions.
In the Baca boiler, the combustion process takes place in a controlled and efficient manner. During the combustion of hard coal, fuel gasification occurs – gases generated in the combustion process are post-combusted in a specially designed chamber, which translates into higher thermal efficiency and a smaller amount of unburnt residue in the ash.
The body of the Baca boiler is made of high-quality 6mm thick steel sheets, ensuring durability and resistance to operation in demanding conditions.
The Stalmark Baca boiler meets strict environmental requirements and is certified for Ecodesign and Class 5.
This solution is dedicated to people who appreciate the simple operation of a manual boiler while maintaining high efficiency and ecological combustion parameters. It will work well in single-family homes, farms, and facilities where reliability and low operating costs are a priority.
