Technology makes the difference

Heat (almost) any wood fuel

In addition to log wood, the HDG Euro 30-50 can also be fired with waste wood, wood chips, shavings or even pressed wood briquettes. Two things make this possible: the practical filling from above ("top loader") and the unique combustion technology.

In order to guarantee the highest life expectancy with all its fuel flexibility, this "all-rounder" has also been designed to be extremely robust.

This makes the HDG Euro the most flexible wood heater for almost any application.

Built to last

The HDG Euro is designed to be extremely robust. The filling shaft wall made of 10 mm thick quality sheet steel and the solid air-cooled cast burner nozzle ensure an uncompromisingly long life expectancy.

Scale liner: for added protection

On request, the fuel chamber can be fitted with a scale liner. This further optimises the boiler protection, especially when many different fuels are used. The conical fuel chamber facilitates movement of the fuel.

Efficiency at top level

The particularly large surface area of the heat exchangers guarantees optimum heat transfer. Together with the extremely clean afterburning in the modular, hinged combustion chamber, your heating is permanently eco friendly and clean.

Sensor-controlled combustion

The flue gas temperature sensor and lambda sensor provide the reference variables for combustion. This means the required combustion air can be continuously regulated via the actuators for primary and secondary air. The result is the lowest possible emissions and low wood consumption.

Practical top loading

Thanks to the unique top loading, other wood fuels, such as wood chips or shavings, can also be used in the HDG Euro in addition to "standard" 1/2-metre logs, in conjunction with the scale liner. For maximum safety, the fuel chamber door has been equipped with a pneumatic support and a safety lock.

Experience greater convenience

Practical convenience highlights, such as the optional HDG automatic ignition system for automatic and on-demand ignition, large ash containers for infrequent ash removal and easily accessible cleaning openings, make the HDG Euro a convenient all-rounder.
