Depending on your needs, the stove can be equipped with heat storage, domestic hot water or central heating, drying, baking, or smoking functions. It can also be equipped with a burner for burning pellets or liquid fuels.
in short
One device, many advantages
It is suitable for all places that need stable heat and does not require access to classic infrastructure.
Useful in field conditions and wherever preparing a hot meal is as important as heating the room.
Helps dry clothes, equipment, supplies... It is indispensable after working in the field or in difficult weather conditions.
The storage module improves heating efficiency by reducing fuel consumption and stabilizing heat release. This allows rooms to maintain a stable temperature while using only a small amount of fuel. Infrared radiation penetrates the body, warming its internal tissues, resulting in faster, more stable, and healthier heating. It operates similarly to tiled stoves and solar radiation.
Thanks to its modular design, the device can be expanded to include domestic hot water heating. This is particularly important when larger volumes of water need to be heated, for example for hygiene purposes or for small children.
Thanks to its modular design, the device can be expanded to power a central heating system. This is important when heating multiple rooms is needed.
Can operate on many types of fuel. It is certified to burn wood, briquettes, and pellets. However, in extreme situations, when human life and health are at stake, it can also burn various uncertified fuels—even liquids like used cooking oil or used engine oil. In crisis situations and during shortages, this can save lives and health.
Its unique smoke-burning design allows the stove to generate heat not only from the fuel burned but also from the smoke burned. This allows for the generation of more heat from the same amount of fuel. This means that less fuel can be burned to produce a given amount of heat.
Most modern heat sources have electric controllers, fans, and feeders, making them ineffective during power outages. Our device is designed to operate entirely mechanically and requires no electrical power, making it resistant to power outages and other crises.
Advanced post-combustion technology makes the exhaust gases completely invisible within minutes of starting combustion (the device requires several minutes to warm up). This increases the stove's efficiency and reduces the visibility of its users.
The device can be equipped with an exhaust gas cooler, which allows more heat to remain in the heated room and makes cool exhaust gases much less visible in infrared light. This is especially important in applications where reduced heat signature and discreet use are important.
It can be easily installed and dismantled in virtually any room. It can also be easily dismantled when not in use. This is particularly important when using this device as a heating system during emergencies and crises. It can also be easily expanded with additional modules.
This is very important for everyone (local governments, companies and individuals) who want to be prepared for times of crisis.
The design makes lighting and daily operation easy, even for those who have never used a solid fuel stove before. Assembly, cleaning, and maintenance are performed using two standard keys. Daily use is 100% manual. This is a particularly important feature during crises and conflicts, when access to advanced tools and services is limited.
Years of experience in optimizing combustion processes, leveraging the latest scientific advancements and the practical knowledge of numerous experts, have led to the development and refinement of this project, making it the best solution available on the market.
The device is designed to be expandable with additional modules at any time. Their configuration can be easily adapted to your needs. It is very durable, but if any part is damaged, we offer all replacement parts.
This applies to both the furnace and its modules and spare parts.
The project can be developed with commercial partners, distributors and field testers.
Heats where standard solutions stop working.
A device designed to work where other systems stop coping: at home, in workshops, in the field, during blackouts, natural disasters and even under extreme wartime conditions.
Smoke-burning technology, cool exhaust, full independence from electricity supply and the ability to extract heat from almost any available fuel make this stove one of the most universal autonomous heating systems.

practical applications within one modular structure
Universal and economic multi-fuel heating for homes, shelters, garages and off-grid use.
This device is intended for use in critical situations and is intended to obtain thermal energy from the combustion and gasification of biomass - in particular wood, briquettes, pellets, chips and waste, as well as cones, branches, sticks, furniture and other wooden elements. It can also burn fuel oil, diesel oil, used oil, used cooking oil... everything that is available during the crisis.
When operating with nominal parameters, no smoke comes out of it, but exhaust gases do. Therefore, if the fuel contains toxic or aggressive substances, the exhaust gases emerging from it will also contain them. We strongly advise against burning waste as it is inconsistent with environmental protection principles.
Because this furnace can be used in many different places and configurations, we have designed it to adapt to individual needs and possibilities. This is probably the only device that can discharge exhaust gases in any direction.
100% Polish engineering thought. 99.99% Polish-made components.
100% Polish engineering thought, 99.99% Polish-made components.
We support Polish companies, specialists and the local economy, which is why the device is developed and manufactured in Poland.
From the initial technical concept, through the structural design, to the production of components, we strive to source all its elements from Polish suppliers – from steel, its processing, paints, and insulating materials, to seals, packaging, and transport companies. Currently, only a few rivets and rivet nuts are not sourced from Polish manufacturers. Everything else is Polish.

Creator of the concept and stove
The concept and stove were created by Dr. Eng. Sebastian Kamil Kostkowski, who earned his doctorate in engineering and technology sciences in 2022. His multi-year research focused on supporting combustion processes.
He became interested in combustion processes from an early age. He learned from stove fitters, manufacturers, practitioners and enthusiasts, and later carried out his own scientific research under the supervision of distinguished professors.
He is a practical and pragmatic person. With his education and passion for environmental protection, he understands the realities of life. With today’s geopolitical realities in mind, he designed a stove that works without electricity, uses a very wide range of fuels, makes highly efficient use of even small fuel loads, produces no visible smoke and can be deployed in many different scenarios.

How it works
It burns little, releases a lot, and heats for a long time.
Our heating system was designed for situations where traditional heating sources fail – such as power outages, gas shortages, or access to certified fuel. The device utilizes an advanced biomass gasification and combustion process. This technology burns smoke during secondary combustion. Improved thermal exchange processes ensure that exhaust gases exit the heat exchanger cool and transparent, making them less visible in infrared light.
