Impressive in every detail
The new version of the HDG Compact 30-149(E) wood chip boiler combines established technology with a range of technical enhancements. The improved PLUS cleaning system, standard ash removal, and faster installation through complete pre-assembly and a reduced number of connections are among the key features of the latest generation. An integrated fine dust separator supports operation with approved coarser and ash-rich fuels, subject to the applicable fuel specifications.
In short: From fuel feed to ash removal, the HDG Compact 30-149(E) offers practical solutions across the entire system design.
Efficient combustion chamber design
With its high combustion temperatures, the high-temperature combustion chamber supports stable combustion conditions during operation. The overfill protection with integrated safety shutdown via a heat-resistant stainless steel push-button tube contributes to safe operation during the combustion process.
Tilting grate technology for automated ash removal
For ash removal, the tilting grate made of solid cast iron is tilted by more than 90 degrees. This helps remove combustion residues from the grate. The residual glow zone can support the continuation of the combustion process after the tilting grate has been closed.
Combustion chamber temperature sensor protects the boiler
The combustion chamber temperature sensor supports stable operation within the intended power range, even with varying fuel quality, and helps protect components by limiting the combustion chamber temperature. Together with the lambda sensor, it supports controlled combustion and low emission levels during operation.
PLUS cleaning system: Heat exchanger surfaces kept clean
The new movable turbulators clean the heat exchanger surfaces thoroughly and help maintain heat transfer performance. Thanks to the new drive mechanism located in the cooler lower section of the boiler, accessibility has been improved and component durability can be supported.
Automatic ash removal for enhanced convenience
Ash removal augers convey combustion residues from the combustion chamber, fly ash chamber and filter system automatically into the ash containers. There, the ash is compacted in large-volume ash containers, helping to reduce the frequency of emptying.
Practical ash container with Euro interface
The HDG ash container with Euro interface can be handled using standard tractors equipped with a compatible interface. The mechanical discharge system can simplify ash handling, while the large filling volume of 230 litres can help reduce emptying frequency.
Practical ash box with Euro receptacle
The HDG ash box with Euro receptacle can be transported using standard tractors equipped with a compatible Euro interface. The mechanical emptying system can simplify ash handling, while the large filling volume of 230 litres can help reduce the frequency of emptying.

Use the entire tree with HDG!
The HDG Vario feed system and the integrated fine dust separator enable the use of approved coarser and ash-rich fuels, including certain wood chip qualities, subject to the applicable fuel specifications.
Integrated fine dust separator
The integrated fine dust separator is designed to support the use of approved ash-rich fuel qualities. As it is integrated into the boiler, only limited additional installation space is required. Fine dust collected by the separator is removed automatically and conveyed to the central ash container together with other combustion residues.
Advantages:
- Suitable for approved ash-rich fuel qualities, subject to the applicable fuel specifications
- Electrostatic separator is designed to separate fine dust particles from the flue gas stream during operation
- Thanks to integration in the boiler, only approximately 5 cm of additional installation space is required
- Automatic cleaning system for the electrode and separator surfaces
- Integrated filter ash removal into the central ash container
- Low flue gas pipe connection, suitable for many existing chimney systems
Absolute control
Perfectly regulated with the HDG Control
The new HDG Control is the intelligent control centre for your entire heating system. Whether on the large touchscreen on the boiler or via the app: With HDG Control, you always have absolute control over your heating system.
- Control of combustion and output
- Control of external heat sources
- Integration of solar thermal systems, accumulators, heating circuits, mains pumps
- Domestic hot water preparation, etc.
- On request: Full web access and app for iOS and Android
From the warehouse to the boiler
Flexible delivery system and feeding technology for every area of application
A sophisticated delivery and feeding system is crucial for the safe and reliable operation of an automatic wood heating system. With clever innovations, the new HDG Vario system sets standards here.
- Cut-Connection: Huge transfer opening between the auger and the rotary feeder reliably prevents material blockages
- 4-chamber rotary feeder: Combines absolute back burn protection
- with minimal component stress due to low friction surfaces
- Stoker auger with dosing container: The fuel dosage via light barrier guarantees an even material supply and constant output even with different fill levels in the warehouse
In addition, with several delivery systems for wood chips (flexi blade delivery system, hinged arm delivery system, walking floor delivery system, etc.) and pellets (suction system, auger delivery system), solutions are also available for fuel transport for every application.
