Manual fired boiler for coal PEREKO KARBO

The KARBO series heating boilers are designed for installation in central heating systems in single-family homes, garages, and utility rooms. They are intended for operation in gravitational or forced-circulation open water central heating systems, which are equipped with safety measures in compliance with the PN-91/B-02413 requirements.

NOTE! It is required that the boiler operates with an accumulator tank.

Advantages:

High-quality boiler steel ensures long-term integrity and increased corrosion resistance.
Multi-pass flue gas channel ensures efficient operation and reinforces the boiler's structure.
Ceramic catalysts enhance combustion and reduce pollutant emissions.
Large loading chamber allows for coal combustion.
Classic moving grate facilitates cleaning.
