Why choose the Solarbayer BioX wood log boiler?

The BioX wood log boiler not only convinces optically. The separation of the heating, filling and combustion chamber doors allows a comfortable heating up and reloading. The large filling chamber enables a long burnoff period with minimum effort. An integrated flue gas outlet prevents the generation of flue gas in the boiler room and offers a smokefree reloading of the boiler. The cleaning of the BioX is very userfriendly due to its semirespectively fully automatic heat exchanger cleaning (optionally available). The extremely low amount of ash can easily be removed through the ash door.



Convincing technology

The double hightemperature cyclone combustion chamber and the used silicone carbide (SiC) that acts like a catalyst, provide for a particularly efficient and clean combustion process with very high efficiency and minimum emissions. The nitrogen oxide output is extremly low and the respirable dust pollution is hardly measurable.

By using highquality and very robust components (e.g. combustion chamber bricks made of SiC) the BioX offers an extremely long service life with minimum followup costs. The wood gasification boiler BioX from Solarbayer is exemplary environmentally friendly and economical.

Why heating with wood?

Wood is the most natural and oldest fuel in the world. A healthy forest is not only a complex ecosystem and habitat, but one of the most determining factors for the global climate. Especially its role as carbon storage and producer of oxygen is essential for survival to humans and nature! Heating with wood is the best alternative compared to fossil fuels. The renewable raw material will replace common energy soruce in the long run. A tree is grown up to a usable size in 70 – 90 years whereas coal and oil need 50 - 300 million years for the comparable amount of energy.

Co2 cycle

With the combustion of wood only the amount of carbon dioxide required by the plant during growth is released. Thus, the raw material is on the one hand a reservoir for current emissions and at the same time a fuel for subsequent generations.

Wood as fuel is not only carbon neutral, but also cheaper. It is not exposed to fluctuations in price of oil and gas and not dependent on global political crises. It promotes regional added value and makes the consumer a little more independent.

Heating with wood is not only ecological but also economical. The use of the local raw material supports the regional agriculture. The stable lower price compared to fossil energy sources in connection with state subsidies for biomass plants are reason enough to rely on the natural raw material now.




Convincing details

BioX cutaway model

  1. Speedcontrolled induced draft fan, rotatable
    Provides for best combustion and reliable suction of flue gas due to its high suction power. Extremely practical: The flue gas pipe is flexibly adjustable to the appropriate angle.
  2. Turbulators with automatic heat exchanger cleaning
    No more dirty hands: the standard heat exchanger cleaning with external hand lever. A fully automatic heat exchanger cleaning can be optionally added. It cleans the heat exchanger completely independent at regularly intervals.
  3. Double cyclone combustion chamber made of silicon carbide (SiC)
    The new unique geometry and the resulting perfect mixing of the fuel gases with oxygen acts like a catalyst and guarantees the cleanest possible combustion with an extremely high efficiency. The nitrogen oxide output is extremly low and the respirable dust pollution is hardly measurable.
  4. Large fuel chamber with optionally available stainless steel lining
    The fuel chamber respectively the gasifying chamber is comfortably loaded from the front, the optionally available stainless steel lining reduces tar formation at the inner walls for a long period of time and protects the boiler walls from severe hits with wood logs.
  5. Comfort-heating-door
    For easiest and fastet heating up of the completely filled fuel chamber, e.g. with organic igniters made of wood wool. Special advantage when cleaning: The fuel chamber is easy to clean due to the groundlevel door arrangement.
  6. Active exhaustion of low temperature carbonisation gas
    Almost no smoke emission when refilling: Opening the filling chamber door to top up fuel automatically activates the exhaust gas fan via the door contact switch. Lowtemperature carbonisation gases are powerfully exhausted by the upper flue pipe register to the back.
  7. Lambda sensor and exhaust gas temperatur sensor
  8. Servomotor with washer disc for finely dosed, perfect combustion air inlet
  9. Control unit and controller
    The lambda control unit with its highcontrast display is easy to handle and shows all important operating parameters. The operation is carried out via large buttons so that these can also be pressed when wearing gloves. It is easy to wipe off. The control unit supervises the exhaust gas values permanently and ensures a combustion with the lowest possible emissions and maximum efficiency even with changing fuel quality.

* With a ceiling height below 2,20 m with BioX 25/35/45 and below 2,00 m with BioX 15/20 the version with split turbulators is necessary.
** Legal regulations and requirements for subsidies have to be respected.
*** Needs to be dimsioned larger depending on pipe length, number of bends, mixing valves, changeover valvex, etc. The here stated pipe dimensions are only a recommendation and to not replace professional technical planning.

Attention: If the optional available boiler front door is mounted the total length of the boiler is elongated about 6mm. With the optional available stainless steel fuel chamber cladding the fuel chamber capacity is slightly reduced.
