When you don't compromise on heating with wood stoves. The pioneering BLAZE SPIRIT wood stoves significantly reduce fuel consumption and overall make their operation easier. Thanks to the automatic heat retention system with mechanical fuel detection, they extend both the burning time in the wood stove and the heat radiation after the fire goes out for up to 8 hours. Combined with intuitive power regulation and a spacious loading chamber, they provide comfortable and economical heating without unnecessary worries.

Three wood logs, all day of heat

What if your wood stove provided heat for up to 8 hours after the fire had faded, consumed 30% less wood, and knew when the fuel was gone? What if you only needed to refuel it three times a day – with no need to relight it? The BLAZE SPIRIT wood stove, thanks to the combination of 3 pioneering patents, significantly simplifies traditional heating and efficiently manages heat.

Unlike regular wood stoves that need refueling every hour, the SPIRIT wood stove only needs to be loaded once every 8 hours. After lighting, a 2-hour flame burn follows, during which the heat is intentionally distributed between the heated space, the wood stove’s accumulation, and the heat retention layer. The goal is to ensure a consistent and smooth heating process with effective heat management, without the negative effects of overheating.

50% of the heat transferred through the stove surface

After loading and lighting the wood stove, only 50% of the heat is transferred directly through the surface into the room. This immediate radiant output is sufficient for quick and even heating without unnecessary overheating.
The remaining thermal energy is intentionally stored for later, thanks to the combination of automatic heat retention and the wood stove’s construction. During 2 hours of burning (4 kg of wood), a thick layer of glowing embers forms in the wood stove, under which the air supply is stopped by mechanical detection of the wood. This prevents unnecessary heat loss through the chimney and increases the overall heat efficiency.

25% of the heat is stored in the ember layer

After the fire has gone out, approximately 25% of the energy remains in the wood stove in the form of hot wood charcoal weighing about 1 kg. This "hot accumulation reserve" forms the basis for flameless combustion, which continues in the following hours. Thanks to this, the wood stove automatically switches to the so-called heat retention mode, where it continues to emit pleasant radiant heat without the need for further operation. Thanks to this hot reserve, the BLAZE SPIRIT wood stove is able to transfer more heat into your home while reducing wood consumption by up to 30%.

25% of the heat in the form of accumulation

The last form of heat accumulation is the wood stove's construction itself. After the fuel has burned, up to a quarter of the produced energy is accumulated in the specially designed material of the internal combustion chamber. It then maintains a temperature of up to 250°C, which is gradually transferred to the surface.
This thermal energy reserve serves as a stable source of radiant heat which, together with the thick ember layer, not only provides higher efficiency but also longer thermal comfort.

Up to 30% less wood. Up to 99.9% more comfort and joy.

Imagine a wood stove that reignites itself even 8 hours after the fire has faded – all you need to do is add more wood. Thanks to the automatic ember-retention system, the BLAZE SPIRIT wood stove saves energy, fuel, and time.

The BLAZE SPIRIT wood stove distributes heat more evenly over time. After 2 hours of burning a single load of wood (approx. 4 kg), only 50% of the heat is released into the room. The remaining energy stays stored inside the wood stove in the form of heat accumulation and a layer of glowing embers. This heat reserve then gradually radiates warmth for several more hours. As a result, it significantly reduces operating costs by 10–30% depending on usage. Even after 8 hours, if you place wood on the glowing coal layer, the wood stove will reignite itself.
Nothing in the world is truly 100%, and joy or comfort are hard to express in percentages. But we stand by our word that BLAZE SPIRIT will make heating with a wood stove noticeably easier.

  • MASSIVE firebox with a mechanical grate

    The spacious firebox made of heat-resistant concrete is designed for logs up to 33 cm long. Its main component is a patented mechanical grate that ensures easy lighting and simple ash removal. With just a few movements of the lever, the ash falls from the loading chamber directly into the ash pan. Ash grating in the stove can also be done with the door closed, preventing dust from swirling in the room. Thanks to its bowl-shaped design, the grate can reliably hold a small amount of ash, which naturally insulates, extends the grate’s lifespan, and supports faster ignition.

  • Vertical grate for even combustion

    After loading the wood stove with wood, just strike a match and light it. The patented vertical grate design, located at the back of the loading chamber, ensures even combustion of the fuel. As a result, the need for frequent wood stove maintenance is reduced, and combustion efficiency is increased. With this solution, the burning time of a single fuel load is significantly extended from the usual 50 minutes to 2 hours.

  • Automatic heat retention

    The system of mechanical detection of residual fuel automatically shuts off the air supply to the wood stove at the moment the fuel burns out and only a layer of hot coals remains. Interrupting the air supply means that the wood stove does not ventilate, thus reducing wood consumption by approximately 10–30% (depending on the operation type). The hot layer then releases the maximum amount of residual heat (without flame) stored in the charcoal and increases the stove's heat retention ability. Additionally, after 8 hours, a new fuel load can be added to the coal layer, which will automatically ignite.

  • More warmth, less maintenance

    Due to the high efficiency of the wood stove, only minimal ash is produced during heating. However, whatever remains in the chamber can be easily cleaned thanks to the dust-free ash removal system, without the need to open the doors.
    With a simple movement of the lever on the side of the wood stove, the ash easily falls through the grate into the spacious ash pan with a 10-liter capacity. This prevents unwanted dust from swirling into the room.
    For everyday heating, ash only needs to be removed once a week. The ash pan is also equipped with a lid to prevent dust from swirling when carrying it out.

Practical features for greater comfort

You can let go of worries about an open fire. The safety feature of automatic door closing ensures your home is always protected.

Smoke protection

Forget about unpleasant smoke when stoking the fire. The BLAZE ELEMENT air redistribution protection system ensures that no smoke or unpleasant odors escape from the wood stove during refueling.

Flexible flue connection and external air supply (EAS)

BLAZE ELEMENT wood stoves offer two flue connection options: the Top variant – top outlet, and the Back variant – rear outlet. The wood stoves are also equipped with an external air supply (EAS) connection, which can be connected either from the bottom or the rear side of the stove.
