TOBY B 12-50
TOBY B is a sophisticated, fully automatic wood pellets boiler aimed for residential buildings.
Sign B stays for „compact dimensions“ of this boiler – it is smaller and weights less than the standard TOBY model and permits easier placement into smaller boiler rooms.
“SET“ version of this boiler is available: By “SET” we mean that circulation pump, expansion vessel and safety valve are all included and pre-mounted into the boiler.
Boiler is completely adapted to burn wood pellet as a primary fuel, achieving maximum efficiency level (90% and more) and a very low exit temperature for flue gases (below 160 °C).
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.
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.
Maintenance and cleaning are reduced to a minimum compared to all solid fuel boilers – only once a week, if not less than that, with a premium quality pellet and proper use.
