Discover the pioneering wood boilers that will reduce your energy bills and make traditional heating easier in 3 key ways.

Reasonable acquisition costs

Advanced equipment, without compromise. With BLAZE boilers, you don’t have to pay for expensive components such as mixing valves – laddomats, pumps or emergency aftercooling systems. They are designed to save you a lot of hassle and last much longer.

  • Loading chamber with improved protection

    The improved design of the chamber with double insulation protects the boiler walls from direct cooling by heating water. This prevents low-temperature corrosion in the loading chamber, thus extending its service life. The double-insulated chamber wall also improves overall combustion efficiency and, unlike conventional boilers, is completely replaceable.

  • No more expensive components (PATENTED)

    Avoid unnecessary expenses. The patented heating water mixing system already integrated in BLAZE HARMONY boilers replaces the classic backflow protection. This eliminates the need to purchase expensive components such as mixing valves – laddomat, pumps or emergency aftercooling for BLAZE HARMONY boilers. The patented mixing system also protects the boiler against low temperature corrosion by means of water temperature control. Together with the double-insulated chamber, this is the second element that increases the boiler’s durability and extends its service life.

  • Possible operation with gravity connection

    Strength lies in simplicity. Another advantage of the patented water mixing system is the possibility of connecting the boiler to the heating system by itself. BLAZE HARMONY boilers can operate even without circulating pumps or in the event of a power failure. This provides their owners with greater independence and also savings on the energy of the circulation pumps.

  • No extra costs for storage tanks + subsidies

    Don’t overpay where you don’t need to. The certifiable power controllability of BLAZE HARMONY boilers allows the installation of a storage tank with a lower volume than required by the standard. For the BLAZE PRAKTIK and BLAZE NATRUAL PLUS model series with a controllability of 30-100%, it is also possible to connect the boiler to the heating system without a storage tank*. All boiler models can be eligible for subsidies.
    *It is important to note, however, that the installation of a boiler without a storage tank is not suitable for all types of building. It depends on the heat loss of the heated house and other characteristics of the specific heating circuit. For more information on the possible installation of a boiler without a storage tank, please refer to the boiler’s operating and installation instructions or contact your installer.

Reasonable operating costs

Make the most of the wood’s energy with a combination of patented technologies – automatic detection of residual fuel, beam nozzle, mechanical turbulators and three-level air handling. Simply get more heat.

  • Automatic ember preservation – one ignition per season (patented)

    Imagine a boiler you only need to ignite once. The mechanical residual fuel detection system used in BLAZE HARMONY boilers makes everyday operation easier. When the fuel has fully burned out, combustion is automatically stopped by switching off the exhaust fan. Thanks to this intelligent detection, a layer of glowing embers can remain in the loading chamber for many hours — creating an automatic ember preservation effect. When fresh wood is added to this ember layer, the boiler reignites automatically without the need for a new ignition. The automatic ember preservation system ensures efficient boiler operation by making full use of the fuel and reduces boiler start-up to just two minutes.

  • Efficient combustion of any wood (patented)

    The three-way air supply ensures uniform gasification combustion 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 (patented)

    Special jet nozzle at the bottom of the 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 increased heat transfer efficiency

    Innovative mechanical turbulators located in the boiler heat exchanger increase the overall heat transfer efficiency and at the same time allow easy cleaning. By simply moving a lever on the side of the boiler, unwanted soot buildup 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

Only 5 minutes of effort – warmth all day. Thanks to its technology, BLAZE HARMONY 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 a hard work.

  • Large loading chamber for effortless refuelling

    The top loading door allows for comfortable fuel loading without unnecessary bending. The top-loading system enables the chamber to be filled with wood up to 90% of its volume — up to 20% more than conventional front-loading boilers. This allows more wood to be loaded at once, which, combined with certified output control and automatic air regulation, significantly reduces the number of visits to your boiler room.

  • Certified power output control for easy adjustment

    Advanced power output control allows the boiler output to be set directly in percentage values and adjusted even during operation. Reduced output settings ensure long burn times while maintaining combustion quality comparable to operation at 100% output. This solution is particularly practical during transitional seasons, when full boiler output is not required. BLAZE HARMONY boilers allow power output regulation from 30% (50%) up to 100%.

  • Easy operation

    The BLAZE HARMONY 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 therefore rely on comfortable, clean and safe stoking without odour and smoke in the room.

    Thanks to the sophisticated design and several protective elements that increase the lifetime of the boiler, we offer you a superior 7-year warranty on the boiler body.

Czech quality

It all started in 2007 with a clear vision: to change the way wood burning is approached. By working with engineers with decades of experience and a focus on development, we were able to bring to market a unique boiler with three patented solutions.

We have grown from a local project into a respected brand that operates throughout Europe and Latin America.

Wood with a future

We believe that wood still has its place in the world of modern heating. It is local, renewable and natural. Our goal is to transform its perception, to process it smartly, without compromise, without dirt, without unnecessary effort.
