TOBY 20-50
TOBY represents one of the most sophisticated solutions for automatic combustion of wood pellets to be found on the market.
It is completely adapted to burn wood pellet as a primary fuel, achieving maximum efficiency level up to 94% and a very low exit temperature for flue gases (below 160 °C). Emission levels of this boiler fulfill the most rigorous norms of European countries.
TOBY 30 is officially tested as a Class 5 boiler according to EN 303-5 at KiWa Institute in Treviso Italy and is eligible for subventions and grants available in most EU countries.
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.
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).
Working principle of this boiler is based on the “sub-pressure” of the heating chamber. 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.
Boiler chamber is made by welding 5mm thick steel plates (all surfaces in touch with fire). Other parts are made of 4mm steel.
The efficiency of this boiler is much higher than that of the conventional boilers with natural air flow.
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.
There is also an anti-explosion safety door on the side of the heating chamber.
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. Please note the handle on the front side of the boiler. This is designated for occasional cleaning of the heat exchanger of the boiler (forcing the ash to fall down to te bottom of the boiler).
