Guntamatic Heiztechnik GmbH

- Model 100 - 400 kW - Pellet Boilers



With the GUNTAMATIC cascade you will benefit from the highest reliability and economy. The proven step grate technology employed by the Biocom matches the boiler output to the current heat demand. This series satisfies even the highest output and quality requirements.


Major economical and ecological benefits can be achieved, particularly in the higher output range. GUNTAMATIC systems are not only CO2-neutral they are also exceptionally frugal in their consumption. GUNTAMATIC cascade systems are distinguished by their high level of reliability and their flexible output adjustment. Quality that speaks for itself.


A clever control program starts the hot air fan quickly and efficiently. Pellets are perfectly consumed at the ideal combustion chamber temperature of around 650 °C. A self-cleaning step grate ensures the necessary movement in the incandescent bed, as well as the ash removal. The combustion gases generated are cleanly converted to energy in a large burnout zone with the aid of a secondary air supply.


The Flex room discharge system transports the fuel from the storage room to the boiler. A cyclonic hopper, with a capacity of 240 litres, permits long combustion times without refills and ensures the best dust separation. The extremely quiet economy drive guarantees the most precise dosing of fuel. The specially developed twin rotary lock valve provides the highest back burning and back smoldering protection, thereby ensuring a long service life for the vacuum turbine. The 'Flex' room discharge screw conveyor ensures a complete discharge, as well as precise dosing into the vacuum flow.


A slow moving ash screw conveyor removes the grate ash into an extremely large mobile ash container. The dust from the heat exchanger cleaning process is also continuously removed into a container that is easy to empty. Options: Vacuum ash discharge with 200 l ash drum for fully automatic transport over a distance of up to 20 m.

  • Regulated incandescent bed temperature: Perfect ash formation, no slag formation
  • Self-cleaning step grate:  The incandescent bed can be changed, subject to fuel
