The rise of the ecological fireplace has transformed the way we think about residential heating, offering a practical, clean and, above all, elegant alternative for those seeking the warmth of fire without the inconveniences of traditional fireplaces.

Sua fluidez se inicia no detalhe curvo em madeira, que conduz o caminhar até a área principal, onde sofás e poltronas são puro conforto e acolhimento. Na composição do piso, um jogo de cheios e vazios dão movimento e leveza ao ambiente, que conta ainda com uma lareira sobre espelho d’água e espelhos estrategicamente posicionados.

The ecological fireplace, also known as ethanol fireplace, alcohol fireplace or fluid fireplace, is a heating system that uses bioethanol (ethyl alcohol) as fuel.

Unlike wood or gas fireplaces, it does not require a chimney, exhaust duct or complex installations. This is due to the fact that the combustion of bioethanol is clean, releasing only water vapor and a small amount of carbon dioxide, without producing smoke, soot or ashes.

This characteristic makes it extremely versatile, and it can be installed in practically any projects, whether built into furniture, inserted in wall niches, or even as an autonomous decorative object. Its simplicity of operation and the absence of residues qualify it as a modern option aligned with the principles of sustainability.

How does it work?

The operation of the ecological fireplace is quite simple and safe, which contributes to its popularity. Basically, it consists of a stainless steel burner, where the bioethanol is stored. When lighting the fuel with a lighter or specific igniter, the flame appears instantly and in a controlled manner.

The combustion of bioethanol generates heat and, as mentioned, does not produce smoke. The water vapor released even contributes to slightly humidify the air, a benefit during dry weather seasons.

The duration of the flame varies according to the reservoir capacity and the size of the burner opening, but in general, one refill can last from 2 to 6 hours. Many models have a lid or lever that allows you to regulate the intensity of the flame and, consequently, the rate of fuel consumption and heat release.

The diversity of models is one of the great attractions of the ecological fireplace, allowing it to adapt to different decoration styles and needs.

  1. Portable: These are models that can be moved freely around the projects, ideal for those seeking flexibility. They can be placed on the floor, on a coffee table or in a strategic corner. Installation is zero, just unpack and use.

  2. Built-in: Perfect for those seeking a more integrated and permanent solution. They can be built into drywall, masonry or joinery niches, creating a clean and sophisticated look. The flame appears to "float" on the wall, giving a touch of modernity.

  3. Tabletop: Compact versions, ideal for decorating coffee tables, side tables or even small outdoor areas. They function as an elegant focal point and add charm to any gathering.

  4. Fire Line (Burners): For more personalized projects, it is possible to acquire only the burner and develop a customized project around it, using materials such as marble, granite, wood or glass. This allows the creation of large-sized fireplaces or those with innovative shapes.

With no smoke, ashes or soot, maintenance is minimal. Just refill the reservoir and, occasionally, clean the burner. There is no need to store firewood, clean chimneys or deal with residues.

Versatility

Since it does not require a chimney or ducts, it can be installed practically anywhere, including in apartments, where traditional fireplaces are not feasible.

Attractive design

Available in a wide range of designs, materials and sizes, the ecological fireplace easily integrates with different decoration styles, from rustic to minimalist. The beauty of the live flame adds a touch of sophistication and warmth.

Efficient heating

Although it is not designed to heat an entire projects like a central system, it generates enough heat to create a pleasant atmosphere and warm the surroundings, especially in smaller or medium rooms. The heat is radiated directly, without losses through chimneys.

Safety

With correct use and the choice of certified models, ecological fireplaces are safe. They feature systems for protection against leaks and excessive heating. It is essential to use only quality bioethanol and follow the manufacturer's instructions.

Space saving

The built-in or tabletop versions take up little space, being ideal for compact projects.
