Switching from oil heating to a pellet boiler
Pellet boilers are an established heating technology used in a wide range of applications. Depending on the building characteristics, heat demand and local conditions, they may represent an alternative to an existing oil heating system.
Depending on the applicable funding programmes and individual eligibility criteria, financial support may be available for the replacement of an oil heating system. The suitability of a pellet boiler should be assessed based on the specific project requirements.
Designed for higher heat demands
The HDG K38-63 is designed for applications with higher heat demand and is suitable for larger buildings, including apartment buildings and public facilities. Despite its output range, the boiler combines a compact footprint with straightforward installation.
It also incorporates many of the features available in smaller HDG K models, including quiet operation, efficient system performance and HDG Control technology.
Fits through (almost) any door
The HDG K38-63 is delivered in separate components and can be brought into the building through a standard doorway. Thanks to its low weight and compact dimensions, the pellet boiler is also suitable for installation in compact boiler rooms.
Easy installation
The HDG K38-63 is supplied largely pre-assembled. Only a small number of components need to be installed on site, without requiring water-carrying connections.
Advanced combustion technology
The combustion technology is designed to support compliance with applicable legal requirements. The precise air control system with a speed-controlled flue gas fan supports controlled combustion processes and reliable operation under part-load conditions, even without an accumulator.
Easy accessibility
Cleaning and maintenance of the HDG K38-63 are particularly convenient thanks to easy access from the front and the large combustion chamber door.
Convenient operation
The burner pot and heat exchanger are cleaned automatically, and the combustion residues are compacted in the large-volume, mobile ash container. Depending on fuel quality and operating conditions, the ash container may only need to be emptied 1 to 3 times per year.
Power-saving and quiet
The HDG K38-63 is designed for low power consumption during operation. In normal operation, only 103 watts are required. Thanks to its low-noise ignition element, the pellet boiler also offers quiet operation.

- Read information and make settings via the easy-to-use touchscreen
- 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 storage technology for every area of application
With pellets, heating can be convenient, including the storage of the compact wood pellets. Thanks to HDG's flexible discharge technology, pellet boilers can be installed in a wide range of building situations and configured to suit individual project requirements.
- Pellet mole: Ideal for individually planned fuel storage rooms and particularly quick to install. There is not usually any need for a sloping floor.
- Pellet suction probes: Most common storage system, because individual rooms are fully utilised. Variants with up to 8 probes are possible.
- Pellet fabric silo: Prefabricated pellet store, which is quickly installed without much planning effort. Can also be placed directly next to the boiler if no extra fuel storage room is available.
