When discussing fireplace emissions, it is essential to distinguish between functional primary heating and targeted atmospheric lighting. Every flame fueled by a combustible substance undergoes a chemical process that releases carbon dioxide (CO2). This applies to wood, gas, bio-ethanol, and also Tenderfuel. However, the context of this consumption is crucial for those wishing to live consciously. Tenderflame positions itself explicitly as an ambient product and not as a replacement for central heating or a heat pump. The purpose of our designs is to add a warm atmosphere to living spaces without the need for a complex chimney or flue. By utilizing the patented steel wick and specifically developed Tenderfuel, a process is created that fundamentally differs from traditional systems. In this editorial, we examine the facts surrounding emissions, the importance of ventilation, and how to responsibly enjoy a real flame at home.

The Science of Combustion and CO2
To understand what happens in a living room when a fireplace is lit, we must look at the science behind the flame. Combustion is a reaction where fuel reacts with oxygen, resulting in heat, light, and byproducts such as water vapor and CO2. This process is universal, whether you light a candle or use a gas stove. The difference between various systems lies in efficiency and byproducts. Traditional wood stoves often release soot, particulate matter, and other substances due to incomplete combustion. Tenderflame, however, works with a patented steel wick that allows the Tenderfuel to burn in a highly controlled manner. Because the fuel only ignites in combination with this specific stainless steel wick, the process is predictable and stable. While CO2 is released, for ambient products, this is of a completely different order of magnitude than for systems designed to heat an entire home. It is therefore important to judge fireplaces based on their specific intended use. An ambient fireplace typically burns for only a few hours at a time, keeping the total annual emissions limited compared to continuous heating sources. The controlled nature of the steel wick ensures that the flame remains steady without the flickering associated with less stable fuel sources.
Ambience Versus Primary Heating
A common misconception is comparing the emissions of a small ambient fireplace with those of a central heating system based on peak values. In practice, the usage pattern dictates the impact. Primary heating often runs for many hours a day at high power to maintain a constant temperature throughout the house. In contrast, a Tenderflame is an experience-oriented product. It provides local heat that is felt as pleasant at a dining table or in a seating area, but it is not designed to replace the thermostat of the central heating. When a fireplace is used purely for atmosphere, the fuel consumption is significantly lower. This automatically means the amount of CO2 produced per evening is restricted. By using Tenderflame as a supplement to existing, efficient heating systems, you enjoy the visual and psychological benefits of fire without the ecological footprint of a wood stove that burns continuously. It is the art of moderation: atmosphere for the moment, technology for the base temperature. This distinction is vital for modern homeowners who prioritize both comfort and environmental awareness in their living spaces.
The Role of Tenderfuel and the Steel Wick
The innovation of Tenderflame lies in the synergy between the liquid and the hardware. Tenderfuel is a liquid that is not flammable on its own. Even if you were to drop a lighted match into a container of Tenderfuel, the liquid would not ignite. The flame only occurs when the fuel is guided through the steel wick and heated there. This safety aspect is a defining characteristic in the world of ambient fireplaces. Because the steel wick does not burn away, the quality of combustion remains constant throughout the product's lifespan. This stands in contrast to cotton wicks or open burners. Testing at institutes such as KIWA and TÜV confirms that this system provides a stable combustion process. For the user, this means a predictable experience without the fluctuations often found in traditional systems. The emissions in this process consist primarily of water vapor and CO2, with the absence of soot and odor being a major advantage for indoor use. It is a technically refined way to bring fire into the home, focusing on safety and ease of use for the long term. This controlled method ensures that the flame remains local and manageable during use.
Air Quality and the Importance of Ventilation
Although Tenderflame offers a cleaner combustion than many traditional alternatives, one must never forget that every combustion process consumes oxygen from the room. Therefore, ventilation is a crucial topic in the manual for every model. In modern, well-insulated homes, the natural supply of fresh air is sometimes limited. When using an ambient fireplace, it is wise to always keep a ventilation grille open or a window slightly ajar. This ensures that the consumed oxygen is replenished and that the produced CO2 and water vapor are vented. Neglecting ventilation guidelines can lead to a less pleasant indoor climate, regardless of the type of fireplace used. At Tenderflame, we always advise users to follow the specific guidelines for their model, as a larger burner requires more oxygen than a small tabletop model. A healthy balance between the coziness of a flame and the quality of the indoor air is easily achieved by simply utilizing the existing ventilation options of the dwelling. It is a small action that significantly increases the enjoyment and comfort provided by the product while maintaining a fresh environment.
Comparison With Other Ambient Systems
When looking at the market for ambient fireplaces, we see various technologies, each with its own emission profile. Wood stoves are atmospheric, but the emission of particulate matter and CO2 is substantial, even in modern variants. Gas fireplaces require a permanent connection and a flue, which is not possible in many apartments. Bio-ethanol is a well-known alternative, but this fuel is highly flammable and falls under strict classifications. Tenderflame distinguishes itself because Tenderfuel is not classified as flammable. This makes transport and storage at home much simpler and less risky. In terms of CO2 emissions per hour, bio-ethanol and Tenderfuel do not differ much if the heat output is similar, but safety during refilling and burning is superior with the steel wick. While bio-ethanol systems can sometimes emit a specific odor due to additives in the fuel, Tenderfuel is optimized for an odorless experience. This makes it a more accessible choice for people who want the atmosphere of a real flame but do not want to experience the disadvantages of traditional fuels in their daily living environment.
- Tenderfuel is safer to store than bio-ethanol.
- No chimney or flue required for installation.
- Patented steel wick prevents unwanted fuel spread.
- No soot formation on ceilings or walls.
Maintenance and Long-Term Efficiency
An aspect often overlooked in the discussion about emissions is the maintenance of the fireplace. A poorly maintained fireplace burns less efficiently, which can negatively affect emissions. With Tenderflame, maintenance is minimal, precisely thanks to the stainless steel wick. This wick never needs to be replaced and does not attract dirt that disrupts combustion. The only thing that can occur is that the fuel absorbs moisture from the air after a long period of inactivity. This can lead to a soft sputtering sound when lighting. This phenomenon is harmless and is caused by the evaporation of microscopic water droplets. To prevent this, it is advised to let the fuel burn off if you know you will not be using the fireplace for a long time, or simply refresh the liquid. By keeping the system clean and dry, combustion remains optimal. This ensures that CO2 emissions always remain within expected parameters and that you do not consume fuel unnecessarily. Efficiency in design directly leads to a more responsible use of resources and a more consistent flame experience throughout the years of ownership.
Conclusion: Consciously Enjoying Fire

Frequently asked questions
Is a Tenderflame fireplace a sustainable choice regarding CO2?
Tenderflame is designed as an ambient product for conscious and measured use. Because it is not intended as primary heating, the total fuel consumption and the associated CO2 emissions per household remain low. It is a responsible way to add ambiance without the high emissions of a wood stove or the continuous consumption of a gas boiler used for aesthetic purposes.
How much CO2 does an ambient fireplace emit per hour?
While exact figures vary by model, an average ambient fireplace at full combustion produces an amount of CO2 comparable to a few large candles or a single gas burner on a stove. This is significantly less than a central heating installation that warms an entire home. Tenderflame focuses on local experience rather than generating massive thermal energy.
Why should Tenderflame not be used as primary heating?
The heat output of a Tenderflame is local and specifically intended for comfort around the unit. For heating an entire home, the fuel consumption would not be efficient compared to systems like heat pumps. Tenderflame should be viewed as a visual and atmospheric element that contributes to the living experience, with pleasant incidental warmth for the immediate vicinity.
