1.2 Product description

• TOBY B boilers are aimed for residential buildings (up to 150 sqm) but unlike TOBY H kamin, B
models are exclusively aimed for boiler rooms. Sign B stays for „compact design“ of this boiler – it
is smaller and weights less than the standard “three-pass” TOBY 20 model.

• 12 KW models can also come in so-called „SET“ versions: SET means that circulation pump,
expansion vessel, safety valve are all included and pre-mounted into the boiler.

• With purchase of additional boiler router, regulation of this boiler can be connected with inter­net: boiler can be turned on/off directly from mobile phone through application (android and ios
supported so far).

• Boiler is completely adapted to burn wood pellet as a primary fuel, achieving maximum efficiency
level (90

• 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. There is a safety
thermostat to prevent back-fire.

• Maintenance and cleaning are reduced to a minimum compared to all solid fuel boilers – only once
a week, with a premium quality pellet and proper maintenance even less frequent.

• Boiler is equipped with a safety pressure sensor – as soon as the boiler door is open – boiler stops
feeding pellets.
