B-Smart
Boiler dimensions and adaptable pellet storage make it suitable for placement in smaller areas.
B-Smart wood pelet boiler is made according to EN 303-5 and fulfills Ecodesign criteria 2015:1189.
Boiler can only be fed and fired with wood pellets that fulfill EN 14961 norm, pellet quality A1 or A2, pellet diameter 6mm or 8mm.
The boiler has an expansion vessel of 8 litres. It is recommended to add an additional expansion vessel of at least 18 litres. Boiler comes with a circulation pump and safety valve inside (beneath the back cover). Air vent is not included.
Original rotating burner design is enlisted at European design registry
This boiler is achieving high efficiency at low exit temperature for flue gases. It is a „Class 5“ boiler according to EN 303-5 and a „7 Stars“ boiler according to French Flamme Verte B-Smart is eligible for BAFA programe in Germany if used with an Airject Filter.
Ignition, start-up and turning-off are fully automatized. Combustion control is optimized using algorithms such as ‘modulation’ which automatically decreases pellet dose as the difference between desired and reached temperature is decreasing.
Boiler regulation is equipped with three sensors (hot-water, flue gas, and heating chamber temperature). A smart PID boiler regulation can „recognize“ the caloric value of the pellets.
It is also equipped with three gear motors (dosing, burner bottomrotation, tubulator automatic clean).
Boiler chamber is made by welding 5mm thick steel plates (all surfaces in touch with fire). Other parts are made of 4mm steel.
Working principle of this boiler is based on the “sub-pressure” of the heating The chamber is completely air-proof so that air flow in the boiler is fully controlled by the exhausting fan mounted on the back. Boiler regulation completely controls the quantity of the air inside the heating chamber: optimum combustion comes as a result.
Pellets are fed to boiler via internal transporter screw inside the storage tank. From there pellets are fed over to heating chamber where they fall free to the designated melting area (the ‘actual’ embedded burner of the boiler). Storage and melting area are physically divided. There is a safety thermostat to prevent back-fire. There is also a pressure sensor inside the heating chamber – when the boiler door is open, this sensor will react and stop the feeding process.
