Benefits

clean combustion and efficient

Our BIOSTAR low temperature boilers are amongst the most innovative pellet heating systems on the market. The flexible combustion concept with variable ember bed height, plus intelligent lambda control, safeguards maximum heating efficiency and compliance with the most stringent emission standards.

affordable installation and operation

Output and boiler water temperature are matched to the actual demand of the building in a unique fashion. As a result, no buffer cylinder is required. Existing oil boilers can be replaced with minimal effort and cost. In addition, the resulting high seasonal efficiency factor ensures very low consumption.

Cleaning has never been easier

Conventional pellet heating systems still require regular cleaning. The Biostar system, on the other hand, cleans the combustion chamber, heat exchanger and grate area (with the exception of general cleaning) automatically. A large ash box reduces the remaining effort to a minimum.

 

perfect storage

Guntamatic storage systems operate with suction discharge and screw conveyor dosing, resulting in outstanding operational reliability and durability. When the fuel is completely used up, there is no need for the annual storage room cleaning. Depending on preference, a high grade steel/mesh hopper or sloping floor storage room with discharge screw conveyor are available.

pioneering, straightforward operating concept:

Fully automatic control of appliance and storage room functions, as well as regulation of the ambient climate utilising the most advanced control technology. Individual adjustments can be made easily via the clear touchscreen controller, possibly via a room control station or a smartphone app.

low maintenance costs, long service life

Advanced technology, robust appliance design and careful manufacture are the cornerstones of success for BIOSTAR systems. They require little maintenance and are built for an exceptionally long service life. Throughout their life cycle, these appliances deliver environmentally sound heating to their owners with the utmost reliability.

Highest level

of convenience

It's all a matter of technology

High grade components

In order to prevent unintentional surprises, BIOSTAR boilers are made exclusively with highest grade components. The robust version of the screw conveyor discharge, the rock-solid motors and gear units and the resilient silicon combustion chamber are but a few examples of this.

Heat exchanger

A countercurrent heat exchanger developed and protected by Guntamatic

ensures a permanently high level of system efficiency in

connection with an automatic cleaning system.

BOX

BOX containers of various sizes are available to suit the dimensions of each available storage room. The steel floor and fabric design is extremely capacious and also allows the container to be emptied completely, thereby reducing the cleaning effort. An screw conveyor-dosing vacuum discharge guarantees highly reliable operation.

FLEX

Guntamatic Flex discharge units are suitable for particularly large, intensively used, storage facilities.
The discharge screw conveyor of the vacuum discharge system has been designed for efficiency and a long service life. It offers a highly reliable operation as well as low cleaning effort,
and discharge from stores with sloping floors. Where the sloping floors are made on site, this is also a particularly affordable solution.

Pellets make their case across the board: most originate in local woods and therefore safeguard local jobs; they represent a climate responsible and CO2 neutral method of heating (currently the only fuel to do so); and save up to 50 % on fuel costs compared to oil, gas or electric heating systems.

Whilst in alternative systems, sheet steel constructions are stressed, the Biostar fireclay combustion chamber generates biomodular energy with extremely high temperatures and a variable ember bed – clean and efficient. This saves costs and protects the environment.
