BLAZE SPIRIT Stove Models

The most efficient fireplace stove with automatic heat retention and 3x longer burning time.

Harmony of man and fire

Wood heating has traditionally been associated with effort, time consumption, and mess. But why not try to change that? That's why we decided to create a new solution in the form of AUTOMATIC HEAT RETENTION technology.

Automatic Heat Retention

Less wood, more heat, no worries. Thanks to the automatic heat retention, the stove takes care of the fuel burnout itself, continues to radiate heat for up to 8 hours after the fire goes out, and saves up to 30% of wood.

Three logs, all day of heat

What if your stove provided heat for up to 8 hours after the fire went out, consumed 30% less wood, and knew when the fuel was gone? What if you only needed to load your stove 3 times a day without the need to rekindle the fire? The BLAZE SPIRIT stove, thanks to the combination of 3 pioneering patents, significantly simplifies traditional heating and efficiently manages heat.

Compared to regular stoves, which require loading every hour, the SPIRIT 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 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 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 stove’s construction. During 2 hours of heating (4 kg of wood), a large layer of hot embers forms in the stove, under which the air supply is stopped by mechanical detection of the wood. This prevents unnecessary cooling of the stove through the chimney and increases the overall heat efficiency.

25% of the heat in the form of the heat retention layer

After the fire has gone out, approximately 25% of the energy remains in the 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 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 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 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, in combination with the heat retention 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 stove that reignites itself even 8 hours after going out – all you need to do is add more wood. Thanks to the automatic ember-retention system, heating with the BLAZE SPIRIT stove saves not only energy but also fuel, hassle, and time.

The BLAZE SPIRIT 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 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 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 stove noticeably easier.

  • ENORMOUS chamber with a mechanical grate

    The spacious firebox made of heat-resistant concrete is designed for logs up to 33 cm in length. Its main component is a patented mechanical grate that allows for easy ash removal and simple lighting. 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 acts as a natural insulation, contributes to its longer lifespan, and helps speed up lighting.

  • Vertical grate for even combustion

    After loading the 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 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 stove at the moment the fuel burns out and only a layer of hot coals remains. Interrupting the air supply means that the 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 heating, less carrying out.

    Due to the high efficiency of the 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 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

Automatic door closing

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 stove during refueling.

Flexible flue connection and external air supply (EAS)

BLAZE ELEMENT stoves offer two flue connection options: the Top variant – top outlet, and the Back variant – rear outlet. The 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.
