The HDG Heating Box is suitable for wood chip, pellet and log wood boilers. Thanks to the modular design of the container system, heating systems with outputs of up to 800 kW can be implemented. The external heating system can be a suitable option where no appropriate installation space for a wood heating system is available within the building to be heated.
The HDG Heating Box is designed for straightforward installation and can also be integrated into a wide range of existing building environments.

The basic version of the HDG Heating Box accommodates HDG log wood boilers as well as matching accumulators, expansion vessels and connections for the heat distribution pipes. Special accumulator sizes are available to support effective use of the available space. This enables space-efficient system integration. In the log wood version of the HDG Heating Box, additional space is available for log storage. On level ground, the log wood can be loaded conveniently.

Heating systems for pellets can also be accommodated in the HDG Heating Box. This makes the heating container a suitable option where the available installation space is not ideally suited to a pellet boiler. Whether as a stand-alone container, in combination with a fibreglass silo, as two containers installed side by side or as a stacked container solution, a range of installation configurations is possible. Suitable fuel delivery systems include the pellet suction system and the flexi blade delivery system.

All models of the HDG Compact and HDG M series can be installed in the heating centre, with dedicated heating box solutions available for these systems. HDG Heating Boxes equipped with automatic wood chip boilers are used in municipal facilities, industrial plants and residential buildings. The optional hinged roof of the HDG Heating Box facilitates filling of the fuel store with wood chips.
