Choosing the Right Fireplace: A Guide to Warmth and Design

The difference between stoves and fireplaces explained

When you delve into the world of fireplaces without a flue, you will encounter various categories. A stove is generally associated with a freestanding object that takes a central place in the room and gives off a substantial amount of heat. At Tenderflame, we see this reflected in models designed to function as an independent piece of furniture. Decorative fireplaces, on the other hand, are more broadly defined and also include compact tabletop models or sleek wall-mounted arrangements that take up less floor space. However, the technical heart of all Tenderflame models remains identical: the steel wick that brings the Tenderfuel to life. Where traditional systems like bio-ethanol often use an open reservoir with liquid, this system works with a fuel that does not ignite on its own. This makes the interaction with the fire fundamentally different. Whether you choose a robust floor fireplace that makes a powerful statement in the living room, or a refined wall model that serves as a living painting, the focus is on a combination of aesthetics and ease of use. It is crucial to remember that natural airflow must be maintained at all times, following the specific model instructions provided in the box.

• Freestanding stoves often offer a higher heat output for larger rooms.
• Wall models save space and serve as a visual focal point.
• Tabletop models are mobile and add ambiance to specific corners.
• All types use the patented steel wick technology.

The technology behind the steel wick and Tenderfuel

The core of Tenderflame revolves around the synergy between the stainless steel wick and the specific Tenderfuel. Unlike bio-ethanol, a liquid that gives off vapours even at low temperatures, Tenderfuel is an alternative that is not classified as a hazardous substance. It burns exclusively when heated via the steel wick. This means that if you were to accidentally spill the fuel, there is no direct fire hazard because the liquid itself does not burn without the wick. This technique has been extensively tested by independent bodies such as the German TÜV, the Swedish RISE, and the Technological Institute KIWA. These validations confirm that the system meets strict requirements for indoor use. The use of a steel wick instead of a cotton wick or an open burner bed also ensures a constant flame and a long life for the burner itself. The wick is designed to last for years without wearing out, provided that one exclusively uses the original fuel. It is this specific combination that ensures one can enjoy a real fire without the complex installation of a chimney or gas pipes, as long as there is sufficient natural ventilation present in the room of use in accordance with the manual. The lack of soot and smoke makes it a clean addition to modern living spaces.

• Steel wicks do not burn up like traditional cotton variants.
• Tenderfuel is not toxic according to testing institutes.
• The patented technology only ignites at the wick surface.
• Burners are tested by KIWA, RISE and TÜV for quality.

Selection based on space and volume

When choosing a suitable model, the size of the room is the most important factor. In a compact studio or an apartment, a large floor model can quickly produce too much heat for the available cubic metres. For such spaces, the tabletop models or smaller wall fireplaces are ideal. They offer the visual appeal of a flame without overheating the room. For larger living rooms, often between thirty and fifty square metres, the larger burners such as those in the Alto series come into their own. These models have a larger reservoir and a wider steel wick, resulting in a more powerful play of flames and more heat output. It is important here that the user consults the manual for the minimum room size in which the specific model may be placed. In rental properties where permanent renovations are not allowed, a freestanding model offers the perfect solution. You can easily take the fireplace with you when moving, which is an advantage over traditional fireplaces. The mobility of the smaller models also makes it possible to move the atmosphere from the dining table to the seating area, depending on the time of day and your specific needs.

• Small spaces benefit from compact tabletop fireplaces.
• Medium-sized rooms are suitable for the Alto or Aris 90 models.
• Large open spaces can accommodate multiple burners or an Aris 180.
• Always check the minimum room volume in the manual.

safe and practical options

Safety and maintenance in daily practice

A frequently asked question is how to safely extinguish and maintain a decorative fireplace. With Tenderflame, this process is very direct. Smaller models can simply be blown out, while the larger models are supplied with a special snuffer. By placing this snuffer over the steel wick, the oxygen supply is cut off and the flame is extinguished immediately. It is recommended to let the snuffer rest on the wick until the next use to prevent contamination and dust accumulation. Regarding maintenance, the steel wick is virtually maintenance-free. If the fireplace has not been used for some time, the Tenderfuel in the reservoir may have attracted moisture from the air. This can lead to a crackling or sputtering sound when lighting, which is simply the evaporation of water particles. This is harmless. One can prevent this by burning the reservoir empty before a long period of inactivity or by simply adding fresh fuel. Cleaning the housing should only be done when the fireplace has cooled down completely, whereby a soft cloth is sufficient. Never use aggressive cleaning agents on the burner unit itself to ensure the integrity of the materials used for the future. Always ensure the device is stable on a flat surface before lighting to avoid any accidental movement during operation.

Heat output as a supplement to main heating

Although Tenderflame fireplaces are primarily chosen for the atmosphere, they also emit a tangible heat. The larger models can provide a capacity comparable to a small electric heater, but with the visual tranquillity of a real flame. This heat is direct and pleasant, which often allows the thermostat of the central heating to be turned down a degree. This makes it an interesting addition for the colder winter months. However, it is not a replacement for a full heating system, but a supplement that brings targeted heat to the place where you are staying at that moment. Because there is no chimney, all the heat produced remains in the room, instead of part of it disappearing through the flue. This makes the efficiency per litre of fuel high. One must always take air quality into account; every form of combustion consumes oxygen, so ventilation via a grille or a window slightly ajar is essential to maintain a fresh indoor climate. This ensures that the humidity and oxygen levels remain at the correct level while you enjoy the warmth and the fire. The absence of traditional wood smoke means no particulates are added to the indoor environment, keeping the air clear and the surfaces around the fireplace clean.

Aesthetics and placement in a modern interior

The design of a decorative fireplace is a decisive factor for many. Tenderflame offers a wide range of designs, from organic shapes with bamboo details to sleek, industrial metal frames. The choice for a specific model is closely related to the existing interior style. A wall model like the Cycloflame can transform a minimalist wall into a dynamic focal point. When placing it, one must take the environment into account: ensure sufficient distance from flammable materials such as curtains or wooden furniture, as specified in the manual. The advantage of the Tenderfuel technology is that no ash, soot, or smoke is released, keeping the area around the fireplace clean. This opens up possibilities for placement in places where a traditional wood stove would be unthinkable, such as in a sleek bookcase or on a glass table. The visual aspect of the dancing flame on the steel wick creates a soothing ambiance that invites relaxation. The reflection of the fire in the glass panels that adorn many models enhances this effect and provides an extra dimension to the light in the room. This versatility allows homeowners to integrate a real fire element into virtually any architectural style.

Why choose the original Tenderfuel

It is of crucial importance to emphasize that Tenderflame products work exclusively with the original Tenderfuel. Many people make the mistake of thinking that all liquid fuels, such as bio-ethanol, are interchangeable. This is not the case and can lead to undesirable situations. The patented steel wick is specifically calibrated to the properties of Tenderfuel. The use of bio-ethanol in a Tenderflame device can lead to uncontrolled flame formation or damage to the burner, because bio-ethanol is much more volatile and already burns without the presence of the steel wick. By sticking to the original fuel, the system maintains its intended operation and integrity. Furthermore, Tenderfuel is formulated to provide an optimal flame height and burning duration. The fuel is safe to handle and can be disposed of via the regular drain if necessary, which underlines the ease of use in daily life. Investing in the right fuel is therefore an investment in the lifespan of the fireplace and the stability of the living environment, whereby one always follows the instructions in the box. The testing conducted by KIWA and TÜV was based solely on this combination, ensuring that the safety profile remains consistent only when the specific fuel and wick are used together as intended.
