ECO H-K Wood Chip Boiler

Boasting unrivalled 95% efficency is one of the worlds leading wood chip biomass boilers.

Full refractory-lined combustion chamber with flame concentration jets for optimum post-combustion

The refractory combustion chamber guarantees high combustion temperatures through optimum heat storage (also at part-load), minimises the ignition procedure and reduces emissions.

Firebed monitoring

Through the exact and contactless firebedheight monitoring system with sensors, the most effective combustion condition depending on fuel quality is detected. Your heating system is always working with the needed heat output at optimum combustion values.
