  • Basic information

    Energy saving and efficient MultiBio 30 pellet boiler

    Pellet boiler MultiBio is a Czech product suitable for comfortable automatic, ecological and economical heating of family houses, residential units and buildings with a loss capacity of 8 to 30 kW. The boiler can be operated both with and without a storage tank due to power modulation. In conjunction with a combined boiler or accumulation tank, the MultiBio boiler can prepare hot water all year round.

    MultiBio 30 pellet boiler design

    MultiBio differs fundamentally due to its unique design from other products on the market. The MultiBio boiler body is three-stroke. With small dimensions, it has a high efficiency of over 90% and a low temperature of the flue gases, which maintains even if the boiler operator is cleaning the heat exchanger once only after the heating season. Unlike single-stroke boilers, there is a significantly better heat exchange between the fire and the heated water in the MultiBio boiler.

    The MultiBio hot water boiler has precisely controlled air and fuel metering for the full range of its output with a working temperature within the burner up to 1200 ° C. The high combustion temperature ensures low emissions without odor and aggressive compounds. MultiBio does not use the damping mode as other retort or cup boilers, in which fuel is still smolder. Thanks to this combustion the boiler does not suffer from self-destruction and does not bother the surroundings by smell from the chimney. The MultiBio boiler has negligible emissions of carbon monoxide and is environmentally friendly. With the MultiBio boiler, you can save up to one third of the fuel costs when heating with lower quality wood pellets and lower prices.

    • The pellet boiler works automatically

      The pellet boiler works automatically

      MultiBio pellet boilers operate automatically over the full power range - including fast, automatic ignition that does not take more than 2 to 5 minutes and full boiler power within 10 minutes after ignition. The automatic boiler can be started by a room equithermal or other conventional thermostat, storage tank thermostats, or remote access via the MultiBio Net Module. The boiler operation only adds fuel and ash extraction takes care of the automatic soap dispenser.

      Make it easy for operators with MultiBio automatic boiler disconnection and motor driven automatic boiler exchanger springs. ////LINK////

    • Using a fuel with high ash volume

      Using a fuel with high ash volume

      The MultiBio burner is a product with a unique combustion system consisting of a pressurized air chamber, a rotary grating with a special drilling, a precision fuel dispenser and a turnstile, which completely prevents fuel from burning back into the hopper without the use of a water canister.

      The MultiBio burner allows you to burn both high quality wood pellets and lower quality wood pellets with high ash or bark contents. The rotating horizontal combustion chamber in the shape of a roller of any grease and a greater amount of ash, during the burning, rolls into the ash compartment and does not bother operating the boiler. Possible specimens do not affect the quality of combustion.

      Wood pellets of the lowest quality with high bark and thus high percentage of sintered ash can not be reliably burned in simple bowl or retort structures.

      The MultiBio burner is an industrially protected product

  • MultiBio advantages

    Comparison of MultiBio boilers and burners with other burners on wood pellets

    Due to their construction MultiBio burners are able to burn fuels with difficulty combustibility, such as plant pellets. In this section of the site, however, we only consider burning wood pellets. If you are interested in the use of fuels other than wood pellets, go to the sites where the burners themselves or the products are certified for both fuels. MultiBio 30 (B) or MultiBio 49 (B)

    MultiBio burners also have a great advantage in burning wood pellets.

    Our customers often ask what are the advantages of the MultiBio rotary burner against bowl burners or square universal burners in connection with the burning of wood pellets. At first glance, it would seem that wood pellets can burn all types of burners on the market. MultiBio burners can also burn pellets whose quality does not match the certificate issued by the dealer to pellets. This is often the case and the pellet dealer can hardly prevent or influence it.

    The primary advantage of the burner is that it is not susceptible to the quality of wood pellets and can burn even the lowest grade pellets that creates ash sinter or even pellets that may contain more minerals and a significant amount of ash or admixtures that can make pellet makers easier production.

    From experience, we know that even if you bought high quality pellets with a certificate, you may find that you have a batch that did not "do". Then there is a situation that you have, for example, 5 tons of pellets in the basement, which the "normal" burner can not burn. Even if the dealer of the poor pellet willingly exchanges, it is necessary to move them out of the cellar. or suffer, remove excessive ash, or specimens from the burner and re-burn the burner. The MultiBio boiler does not do this. It can reliably burn pellets with which the burner or torch burners can not burn.

      Boiler connection with four-way valve

      The connection is used for installations without a buffer tank. The connection uses two independent pumps, one for a short loop of the boiler and the other for holding a circulation of heating water in the heating system. The advantage of the second pump is to ensure full flow in the heating system and even heating of all radiators.

      Principle of regulation of the boiler part of the heating system

      The boiler circuit pump is controlled by the boiler electronics and switches to set temperatures. The shut-off pump draws down the undesired cooling of the storage tank via the boiler body after the system has been tightened together with the backflow preventer.

      The boiler is controlled by two thermostats on the accumulation tank, the upper thermostat is set to 60 degrees and drops below this value at the top of the boiler switching. The lower thermostat is set to 80 degrees and the boiler switches off when the bottom of the storage tank is above this temperature.

      Three-way Valve The Rototemp Firing System ensures that the boiler returns to the required temperature and thus protects the boiler against low-temperature corrosion. It is also possible to use the ESBE thermostatic valve with the largest flow but only for 30 kW boilers.
