Design and user benefits of the boilers PYROGAS



  • PYROGAS boilers are modern hotwater gasifications boilers burning wood and wood briquettes with high efficiency to satisfy the condition of EcoDesign, Class 5 of the EN 303.5, Austrian national deviation under Article 15a, German National deviation BlmSchV, Stufe 2 valid from 1.1.2017, Slovenian EKOSKLAD deviation, standards for Switzerland, Denmark and it is possible to use for their purchase the non-repayable financial contribution from government as such the The new Green Investment, Kotlíková subsidy, Green homes, etc.. Boilers are certified by the notified and accredited testing laboratory under the responsibility of the EU and registered in the German DIBt.


  • Intelligent electronic controller AK5000 using lambda probe LSU 4.9, Belimo servomotors and exhaust fan EBM-Papst controls the combustion process always in optimal operating conditions regardless of weather conditions. Supply of primary and secondary air into the combustion chamber is controlled automatically and through the built-in PID function, that brings emissions reductions and energy efficiency improvements in the fuel, maintain the set temperature of boiler water by the smooth control fan speed.

  • The main functions of the electronic boiler control AK5000: identification of burnout, the possibility of upgrading the software, control of several branches, weather compensation (equitermic regulation) of the central heating, switch on of an external boiler after burning out of fuel, monitoring of boiler via PC / laptop, the boiler can be connected to the home network, remote boiler control via Ethernet / webserver, the possibility of additional expansion about further thermometer inputs and relay outputs, and more



  • Fireproof combustion chamber LACFIRE 1800/20 SiC with the addition of silicon carbide due to its robustness and segment structure provides a high thermal inertia and thermal stability, long life and easy interchangeability of the most thermal exposed parts independently of the others, thus contributing to cost savings in the long-term maintenance. The resulting wood gas is burned completely in a firebeton chamber at temperature up to 1200 ° C with a direct efficiency of the 91%


  • The massive cast-iron grate surface is equipped with firebeton acumulations inserts LACFIRE providing standing-glow of the embers until its completely burn-out and subsequent falling down of the fine ash into a separate ashtray. This design allows to collect the ashes from the boiler during full operation.


  • All sides of the water heatexchanger surface in the area of embers on the grate surface are protected by firebeton shaped bricks as well as the combustion chamber. This solution helps to more ideal release of flammable gas from timber and protects the boiler against the direct contact of embers with the water heatexchanger surface, what has a positive effect on the life of the boiler.


  • Separate rear burning from the ash surface and turbulatorss (flue gases braking) significantly reduce the risk of ash swirling and its share in the flue gases, and the ashes fall into the separate ashtray and not to the combustion chamber.


  • The boiler is equipped with an integrated rectifier of flow of primary air, which ensures an uniform burn-out of embers flare without causing unburned and charred fuel residues.


  • The design of the primary nozzle with a protective cast iron insert ensures reliable burning process without the risk of clogging the nozzle even if of usage of wood briquettes with high extensibility


  • Each boiler PYROGAS can be supplied with a set of accessories (pellet burner, feeder and pellt storage) for heating with wood pellets without the need to buy additional boiler.
