Why drown God in the windows? Make the most of the wood’s energy with a combination of patented technologies – automatic stacker, beam nozzle, mechanical turbulators and three-level air handling. Simply get more heat.

  • Automatic stallkeeper - one flood per season (patent pending)

    Imagine a boiler that you melt only once. The mechanical fuel detection system of BLAZE HARMONY boilers will make your daily heating easier. When the fuel in the boiler burns out, the burning is stopped by automatically switching off the exhaust fan. Thanks to this clever detection, a layer of glowing embers remains in the boiler feed chamber for up to several tens of hours – an automatic stoker. When the wood is reapplied to the stacker layer, the boiler will self-ignite without the need for heating. The automatic stoker system ensures economical operation of the boiler using all the fuel and makes stoking the boiler a 2 minute affair.

  • Efficient combustion of any wood (patent pending)

    The three-stage air supply ensures uniform combustion by gasification with an efficiency of over 90%. This technology, developed by BLAZE HARMONY, can adjust the air ratio itself depending on whether you are burning hardwood, softwood, larger logs or wood with higher moisture content. The result is a longer burn per batch and maximum energy use. With the BLAZE GREEN and BLAZE PRAKTIK boilers, comfort goes even further. Lamda probe-controlled airing controls the combustion completely automatically and without the need for your intervention. This ensures even higher boiler efficiency with minimal emissions.

  • Jet nozzle for efficient combustion (patent pending)

    Special jet nozzle at the bottom of the feeding
    chamber increases combustion efficiency and keeps the fuel in the correct position. Thanks to the original
    shape, it naturally discharges ash without the risk of clogging and thus allows continuous operation of the boiler with lower operating costs.

  • Mechanical turbulators for higher heat yield

    Innovative mechanical turbulators located in the boiler heat exchanger increase the overall heat yield and at the same time allow easy cleaning. By simply moving a lever on the side of the boiler, unwanted debris can be removed from the heat exchanger even during operation without any need to dismantle the boiler. Mechanical turbulators help maintain high boiler efficiency and make overall boiler maintenance easier.

Easy operation and high comfort

5 minutes heating, all day heat. Thanks to its technology, BLAZE boilers also save the most important thing we have – time. Treat yourself to comfort and easy heating – heating in a boiler no longer has to be a chore.

  • Spacious folding chamber for convenient folding

    The top loading door is used for convenient loading of fuel without unnecessary bending. The top filling system allows the chamber to be filled with wood up to 90% of its volume, which is 20% more than conventional boilers. This allows more wood to be loaded into the boiler, which combined with certified power control and automatic airing will significantly reduce the number of visits to your boiler room.

  • Certified power adjustability for easy setup

    Top performance control allows you to directly set the desired boiler output in percentage and control the boiler during operation. The reduced power setting ensures a long burn time in the boiler with comparable combustion quality as when the power is set at 100%. This solution is particularly practical during the transition period when full boiler output is not often required. The output of BLAZE HARMONY boilers can be controlled from 30 (50) % to 100 %.

  • Easy operation

    The BLAZE boiler can be operated by every member of the family – from grandfather to grandson. Thanks to a high level of automation and minimal intervention, it takes care of everything by itself. The boiler control unit can communicate with the entire heating system of the house, controlling heating, water heating and the storage tank. Make heating with wood easier once and for all.

  • Clean operation with no risk of smoke leakage into the room

    Forget about unpleasant smoke when opening the boiler. Thanks to the clever smoke detection system, the BLAZE boiler itself recognises when you want to add wood. Before opening the door, it sucks the smoke from the feeding chamber directly into the chimney. You can thus rely on comfortable, clean and safe stoking without odour and smoke in the room.

Pro snadné ovládání a obsluhu kotle

Automatická řídicí jednotka ecoMAX

Řídicí jednotka ecoMAX přináší pohodlné ovládání kotle prostřednictvím intuitivního dotykového displeje. Díky ní lze regulovat výkon v rozsahu 30–100 % bez ztráty účinnosti či kvality spalování. Inovativní technologie kotlů BLAZE HARMONY zajišťuje, že i při snížení výkonu ze 100 % na 50 % zůstává spalování stejně efektivní – pouze probíhá po dvojnásobně dlouhou dobu. Regulátor současně dohlíží na maximální teplotu vody a chrání systém před přetápěním.

Automatická řídicí jednotka umožňuje provozovat kotel na nižších výkonech (důležité zejména v přechodném období) a instalovat menší akumulační nádrž, což vede k výrazné úspoře financí i prostoru.

Regulátor také vyhodnocuje hodnoty O₂ naměřené lambda sondou a na jejich základě řídí přívod spalovacího vzduchu tak, aby udržel nastavenou hodnotu zbytkového O₂ a zároveň zajistil co nejkvalitnější spalování s nižší spotřebou paliva.

Řídicí jednotku ecoMAX 960D lze rozšířit o modul P, který rozšiřuje možnosti ovládání vytápění. Tento modul umožňuje nejen řízení spalování pelet, ale také správu solární instalace, ohřev akumulačních nádrží a regulaci přívodu vzduchu do kotelny. Díky těmto funkcím je modul vhodný i pro kotle na dřevo, u nichž lze takto přidat pokročilé funkce a rozšířit jejich možnosti.
