A cozy fireplace used to be inextricably linked to major renovations, such as laying a gas pipe, installing a flue or creating new power points. Today, that dependence on fixed infrastructure is a thing of the past. A fireplace without installation offers the possibility to introduce a lively, dancing flame in almost any room without the need for an installer. This concept relies on the innovative combination of a specially developed liquid and a patented burner technology. Instead of a system that must be continuously fed via external channels, the fireplace functions as an autonomous object. The result is a high degree of flexibility in interior design, where the fireplace can be placed wherever the atmosphere requires it, independent of the walls or the roof. You only need to consider the basic instructions from the manual and the necessary ventilation for your specific Tenderflame model.

The limitations of classic fireplace connections
The traditional open fire or gas stove is always tied to the architecture of the house. A wood-burning fireplace requires a vertical flue that must protrude through the roof, which is simply not possible in many modern apartments or terraced houses. Gas fireplaces in turn require a safe gas pipe and often a wall terminal, which is accompanied by high installation costs and periodic maintenance of the burners and pipes. Even electric fireplaces, although easier to place, are limited by the proximity of a wall socket and the need to hide cables. These dependencies make it difficult to arrange an interior flexibly. When you decide to change the layout of the living room, the fireplace remains a static point that cannot move with you to another corner or room. A fireplace without installation breaks these conventions. It allows you to enjoy fire in places where it was previously technically unfeasible, such as in a home office or in the middle of a room, without a mechanic needing to drill holes or pull pipes. The focus shifts from technical feasibility to purely aesthetic desires, allowing the homeowner to prioritize design and ambiance over the constraints of the building structure.
- No expensive renovations for chimney flues.
- No risk of gas leaks or malfunctions in the gas supply.
- Complete freedom in the layout of your interior.
The technology behind the connection-free fireplace
The heart of the Tenderflame collection is the patented stainless steel wick. Unlike traditional systems where a liquid is directly ignited, only the Tenderfuel that is transported up by the steel wick burns here. This process ensures a controlled and stable flame. The technology is characteristic because the fuel itself, Tenderfuel, does not burn under normal conditions. Only when the liquid comes into contact with the heated steel wick and reaches a temperature where evaporation occurs, does the flame arise. This makes the system fundamentally different from a bioethanol fireplace, where there is often an open reservoir with flammable liquid. The Tenderflame burners are designed to work without pumps, fans, or electronic sensors. This means that no power is required for operation. The energy comes entirely from the combustion of the Tenderfuel on the steel wick. Because there is no soot formation or smoke development, the need for an outlet to the outside is completely eliminated. It is a closed process where the technology is integrated into the fireplace itself, which reduces installation to simply unpacking and filling the reservoir according to the provided instructions.
Tenderfuel: The safe fuel for indoors
When designing a fireplace without installation, the choice of fuel is crucial. Tenderflame uses Tenderfuel, a liquid specially developed for use in combination with the steel wick. One of the most important properties of Tenderfuel is that it is not classified as toxic or flammable. This offers a significant advantage when storing and refilling the fireplace. If you accidentally spill some Tenderfuel on the table or your hands, there is no immediate danger, as the liquid only ignites under the specific conditions of the steel wick. This safety has been extensively tested by renowned institutes such as KIWA, the Swedish RISE and the German TÜV. Thanks to these properties, the fireplace can be safely used in the home without the need for complex fire safety systems. Because Tenderfuel burns cleanly, no harmful residues remain in the burner, which benefits the life of the steel wick. The lack of odor and soot ensures that the fireplace can be placed in various rooms, from the bedroom to the dining room, without affecting the environment. Refilling is easy and can be done without spilling, provided the instructions in the manual are followed for wetting the wick before lighting it with a gas torch.
- Not toxic and not classified as flammable.
- Safe to handle and store in the home.
- Tested by KIWA, RISE and TÜV for maximum reliability.
Ease of installation and freedom of placement
A fireplace without installation means in practice that you can enjoy an atmospheric fire within minutes of receipt. The installation is limited to placing the fireplace on a flat, stable and non-combustible surface. There is no need to take into account the distance to a socket or the position of the ceiling relative to a flue. This also makes the fireplaces extremely suitable for rental properties, where permanent changes to the structure of the building are often prohibited. You simply take the fireplace with you when you move. Although no physical connection is required, ventilation remains an important aspect. Every form of combustion consumes oxygen, so good air exchange in the room is necessary, exactly as described in the manual of your specific model. This can often be achieved by opening a window slightly or via the home's existing ventilation system. The portability of the smaller models, such as the tabletop fireplaces, allows you to move the atmosphere from the dining table to the coffee table or even to a sheltered terrace. You are no longer bound to one fixed spot for warmth and coziness, giving you the liberty to redesign your space whenever you feel the need for a change.
Comparison with other atmospheric fireplaces
When we look at other systems that claim to require no connection, we often see disadvantages that are absent in Tenderflame. Bioethanol fireplaces, for example, use a liquid that is highly flammable. This brings risks when refilling, especially if the burner is still warm. Electric fireplaces are indeed safe, but often lack the dynamics and the heat of a real flame. Moreover, they are always dependent on a cord, which limits the placement options. Candles provide atmosphere, but the amount of light and heat is minimal compared to a Tenderflame burner. Furthermore, candles can soot and drip. Tenderflame offers a hybrid solution: the real flame of a combustion fireplace with the convenience of an electrical appliance. Because the steel wick does not burn up, it does not need to be replaced like traditional textile wicks. This makes the system low-maintenance. The absence of smoke and soot also means that walls and ceilings stay clean, which is often a major problem with wood-burning alternatives. The system is designed for the modern consumer who wants the benefits of fire, but not the burdens of a complex installation or polluting emissions. It represents a significant step forward in domestic heating and decoration for urban environments.
- No risk of flash fires as with bioethanol.
- Real flames as opposed to projections in electric models.
- No soot or smoke damage to your interior.
Maintenance and long-term use
One of the greatest advantages of a fireplace without installation is the minimal maintenance. Because there are no moving parts in the burner and no electronics are involved, the chance of defects is very small. The stainless steel wick is designed to last for years without losing quality. The only periodic maintenance consists of cleaning the glass panels and keeping the housing dust-free. If the fireplace has not been used for a while, the Tenderfuel in the reservoir can attract moisture from the air. This can lead to a popping or sputtering sound when relit. However, this is harmless and easy to solve by replacing the old liquid or letting the fireplace burn completely empty. It is important to always use the original Tenderfuel; other fuels such as bioethanol can damage the steel wick and cause dangerous situations. Due to the simplicity of the construction, the fireplace remains reliable. You do not need to schedule an annual inspection by a chimney sweep or gas technician, which saves considerably on costs in the long term. This reliability ensures that the fireplace is always ready to use when you want to create a warm and inviting atmosphere in your home, regardless of the season or external conditions.
The future of atmosphere in the home
The shift towards homes without gas connections and stricter rules for particulate matter emissions from wood stoves ensure a growing demand for alternatives. The fireplace without installation fits perfectly into this current era. It offers a sustainable way to enjoy fire without directly burdening the air quality in the home with soot or smoke. Architects and interior designers are increasingly using this technology to integrate fireplaces into modern designs where a chimney is not an option. Whether it is a wall model in an apartment or a freestanding model in a spacious loft, the independence from fixed connections offers unprecedented creative possibilities. The technology of the steel wick and the safe properties of Tenderfuel make it possible to combine the ancient attraction of fire with modern convenience and safety. Ultimately, it is about the experience: the warmth and the light of a flame, but without the complexity of the past. It is a mature solution for everyone who values atmosphere, design and ease of use in a modern living environment. As urban living spaces become more compact and energy-efficient, the need for flexible, clean-burning decorative fires will only continue to rise, positioning Tenderflame as a leader in this evolution of domestic comfort.
Frequently asked questions
Can I place a Tenderflame fireplace in a small room without a flue?
Yes, this is possible because the fireplace produces no smoke or soot. However, just like with candles or other flames, oxygen is consumed. It is therefore essential to ventilate the room well according to the manual of your specific model. For small spaces, the compact tabletop models are often the most suitable to maintain a balanced indoor climate.
What happens if I accidentally pour bioethanol into the fireplace?
This is strictly prohibited and dangerous. The Tenderflame is exclusively designed for Tenderfuel in combination with the steel wick. Other fuels such as bioethanol are highly flammable and can lead to uncontrollable flames or damage to the burner. Always use only the prescribed Tenderfuel for your safety and to ensure the longevity of the patented steel wick.
Does the steel wick ever need to be replaced?
The patented stainless steel wick is developed for long-term use and does not need to be replaced with normal use and the correct fuel. Because the wick itself does not burn, but only transports the liquid, no wear occurs as with a cotton wick in a traditional oil lamp. This makes the Tenderflame a very durable choice for atmospheric lighting.
Why does my fireplace sometimes make a sputtering sound?
This usually happens if the fireplace has not been used for a longer period. The Tenderfuel can absorb moisture from the air. When this water is heated, steam is created which causes the sputtering sound. This is harmless. You can prevent this by letting the reservoir burn empty if you do not plan to use the fireplace for a while.
How much heat does a fireplace without installation give?
The heat output varies by model and is generally between 1100 and 2000 watts. Although it is primarily an atmospheric fireplace, it gives off a noticeable and pleasant warmth in the immediate vicinity. However, it is not intended as the main heating for an entire home, but rather as a supplement to the existing heating for added comfort.
