Choosing wood heating systems and wood boilers correctly
Wood heating systems are a proven solution for anyone who wants to heat with log wood, wood gasification boilers, natural draft boilers, or combined solid fuel technology. In the GEMA Shop you will find wood boilers for different output ranges, fuels, and applications – from compact boilers for smaller buildings to more powerful systems for larger living spaces or supplementary heating systems.
When choosing, not only price and manufacturer are decisive, but above all the appropriate nominal output, the fuel, the combustion technology, the efficiency, and the integration into the existing heating system. The filters on this page help to narrow down the selection specifically.
Difference between wood gasification boiler, natural draft boiler, and solid fuel boiler
A wood gasification boiler uses the principle of wood gasification and generally operates with controlled combustion. This allows log wood to be burned more efficiently than with simpler boiler designs. Wood gasification boilers are particularly interesting if you want to heat regularly with log wood and desire as clean and controlled a combustion as possible.
Natural draft boilers are structurally simpler and use the natural chimney draft for combustion. Depending on the model and application, they can be a robust solution for log wood or other solid fuels. Coal gasification boilers and solid fuel boilers complement this area with additional fuel and application options.
Important selection criteria for wood heating systems
- Nominal output in kW: The output of the boiler must match the building, heat demand, and system concept.
- Output class: The classification helps to narrow down suitable devices according to typical output ranges.
- Recommended application area: Information on living space serves only as a guideline and does not replace a heat load calculation.
- Fuel: Depending on the boiler, log wood, coal, or combined solid fuels are possible.
- Combustion technology: Wood gasifiers, natural draft boilers, or coal gasifiers differ significantly in design, operation, and combustion behavior.
- Funding status: Eligible products should always be checked in connection with the currently applicable funding conditions.
Buffer storage and system integration
Many wood heating systems are operated with a buffer tank. The buffer tank absorbs excess heat and makes it available to the heating system at a later time. This can make operation more comfortable and integrate the system more stably in hydraulic terms.
Additionally, depending on the system, return temperature boosting, heating circuit control, safety components, pump groups, chimney accessories, and suitable connection components may be required. These components should always be selected to match the boiler, the output, and the existing heating system.
Note on system design
The filter values on this page are intended as a guide for product selection. The specific design of a wood heating system should always be based on the actual building data, the heat demand, the existing heating system, and a professional heat load calculation.
Frequently asked questions about wood heating systems
Which wood heating system is right for my home?
The right wood heating system depends on the building's heat demand, the desired fuel type, the existing heating system, and the available space. Important criteria include nominal output, output class, buffer tank requirements, chimney requirements, and the intended use. The filters on this page help with an initial narrowing down, but do not replace a professional heat load calculation.
What is the difference between a wood gasification boiler and a natural draft boiler?
A wood gasification boiler operates on the principle of wood gasification and controlled combustion. This allows log wood to be burned efficiently and cleanly. A natural draft boiler is simpler in design and uses the natural chimney draft. Which design is suitable depends on the area of application, the desired operating comfort, and the system concept.
What output should a wood heating boiler have?
The output of a wood heating boiler is specified in kilowatts and must match the actual heat demand. An output that is too low cannot adequately supply the building, while an output that is too high can lead to unfavorable system operation. Details such as living space or output class serve only as a guide. A professional heat load calculation is decisive.
Do I need a buffer tank for a wood heating system?
In many wood heating systems, a buffer tank is useful or required. It stores excess heat and releases it to the heating system later. This allows the system to operate more evenly. Whether and what buffer volume is needed depends on the boiler, the output, the system configuration, and the applicable technical requirements.
Which fuels can be used in wood heating systems?
Depending on the boiler type, log wood, coal, or other solid fuels may be intended. The manufacturer's specifications for the respective product are always decisive. A wood gasification boiler is generally designed for log wood, while solid fuel boilers or coal gasifiers can support other fuel types depending on the model.
Are wood heating systems eligible for funding?
Whether a wood heating system is eligible for funding depends on the specific product, the technical requirements, and the currently applicable funding conditions. In the shop, the "Funding status" filter can be used for orientation. A binding check should always be carried out based on the current funding guidelines and the product documentation.
