Solarbayer BioX wood gasification boilers are perfect for combustion of natural, split logs with 0.5 m log length, with lowest emission values and high energy efficiency, available in sizes BioX 15, BioX 20 (filling volume 125 L) or BioX 25, BioX 35, BioX 45 (filling volume 185 L), optionally available with BioX design front door, fully automatic heat exchanger cleaning and stainless steel combustion chamber.
Why choose the Solarbayer BioX wood log boiler?
BioX is the result of Solarbayers’ many years of experience in the development, production and distribution
of wood log gasification boilers.
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.
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.
With its emissions it is far below the maximum permissible values specified by the German Federal Immission Control
Ordinance (1.BImschV, level 2).
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.
Energy from wood is stored solar energy
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.
Rule of thumb for the energy content of dry wood
Spruce wood (with 15 % residual moisture): approx. 1.300 kWh/rm approx. 130 l fuel oil
Beech wood (with 15 % residual moisture): approx. 1.900 kWh/rm approx. 190 l fuel oil
You can compare and calculate the heating costs with the heating cost comparison tool from Solarbayer Heating cost comparison
Wood gasification boilers are no ordinary boilers. They differ fundamentally in the combustion process from common wood boilers. In order to achieve the best possible combustion it is necessary to ignite the socalled wood gas. Wood gas is a hard to ignite gas consisting of carbon dioxide (CO2), carbon monoxide (CO), methane, ethylene, hydrogene and steam that could reach up to 1100°C when inflamed. But the wood gas has to exhaust from the wood. In the BioX the wood is dried automatically at 200°C. This process starts right after the filling and heating up of the wood gasification boiler in the upper combustion chamber. The residual moisture evaporates from the wood logs. Afterwards the wood starts to decompose and the ingredients lignin and cellulose exhaust as gas from the wood. These gases are ignited and already reach temperatures up to 600°C. Only now the hard to ignite wood gas is released and ignited by the supply of oxygen. The energy stored in the wood is released in the most efficient way and transferred to the heating system in the best possible way. Glowing charcoal forms a bed of embers in the combustion chamber, which is hot enough to dry further wood. At the end an extremely small amount of ash remains.

Stainless steel fuel chamber lining (optional)
The optional hinged stainless steel
plates take care of a decreased tar
formation in the fuel chamber and
protects the walls from severe hits.
Two integrated stainless steel air
distribution plates in the bottom are
Fully automatic heat exchanger cleaning (optional)
No more dirty hands: A fully automatic
heat exchanger cleaning takes care of the
cleaning each time the fuel chamber door
is opened and at regularly intervals.
Clean heat exchanger tubes
guarantee a better efficiency factor and
Left/Right hinged boiler doors
All doors come right-hinged, which
means they open up to the right side.
If it would be more handy to do it the otherway
round, because for example
space is limited in the boiler room, then
the doors can easily be turned by 180°
due to the clever design and mounted on
the other side.

Systems that work - Solarbayer wood gasification boiler sets BioX
The combination of appropriate components is essential for the total efficiency of a wood boiler system!
Solarbayer wood log boiler sets are generelly equipped with patented Solarbayer stratification storage tanks SLS®. This guarantees an immediate and very efficient heat supply to the heating system even at cold buffer temperatures when the boiler is started. Due to the large filling chamber of BioX boilers Solarbayer recommends a minimum storage tank capacity of approx. 12 ltr. each 1 ltr. filling chamber room, to optimize the efficiency of the boiler. Regardless, legal regulations and requirements for subsidies of course have to be respected.
incl. fire protection insulation ISOB1®
(difficult to ignite)
The single components in each set can be changed according to your needs. Our technicians will be glad to advise you.

2 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.
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.
