UNI(K)4, the experience of fire without constraints

This high-end bioethanol heater delivers up to 4,4 kW of heating power for up to 27 hours of burn time, without a chimney, construction work, or permanent installation. It accepts all types of denatured bioethanol (96,6%) thanks to a dedicated, automatically fed burner. With four adjustable flame settings, it offers precise control. Preheating and bioethanol feed technology ensures efficient consumption without compromising the flame's aesthetic appeal or effectiveness, for simple and safe operation.

Assembled in the SEGUIN workshops in Virignin, UNI(K)4 can be installed wherever desired and meets the evolving needs of individuals, hoteliers, and specifiers: an ambient heating device that provides gentle, enveloping warmth in just a few minutes. UNI(K)4 combines modern comfort with a soothing atmosphere, transforming any space into a true haven of relaxation.

A solution to the need for comfort without construction work

In a market seeking flexibility, UNI(K)4 offers a unique solution for providing a vibrant flame and genuine warmth without an exhaust vent. It is suitable for homes and apartments as well as atypical spaces such as lofts, urban studios, tiny houses, charming guesthouses, lodges, verandas, or coworking spaces.

Mounted on discreet casters, it moves freely from room to room. Installation is immediate: a can of bioethanol, a power outlet, and the flame ignites. UNI(K)4 thus meets the demands of new lifestyles, adapting to any space without any constraints.

Thermal efficiency for supplementary use

UNI(K)4 ensures direct heat distribution into the room and offers performance suited to its role as a supplementary heater. Its 4,4 kW output allows it to warm the room in just a few minutes. The temperature rises quickly, and the heat is distributed gently and evenly.

The four power levels, adjustable via a remote control (default), allow you to adjust the flame intensity according to your preferences and needs. Its mains power operation ensures quick ignition.

Exclusive technology for a clean flame

Designed to operate with all 96,6% denatured bioethanols, UNI(K)4 is equipped with an automatic feed burner that ensures precise flame and fuel consumption control. This burner was co-developed with Piazzetta, a partner of the Seguin Group for 20 years.

For safe operation, the UNI(K)4 is equipped with a CO2 sensor and a canister presence sensor. It is recommended to ventilate the room where the unit is installed. It meets the requirements of residential and commercial environments seeking to combine aesthetics and safety. The unit can be used in the presence of children or in hotels and public establishments, in compliance with applicable regulations.

The flare-up as a source of well-being and disconnection

UNI(K)4 does more than just provide heat; it offers a true sensory experience. Its vibrant flame, powered by a high-precision burner, diffuses a particularly warm light, similar to a wood fire, which is one of the best sources of balance for natural light needs.

UNI(K)4 illuminates, soothes and invites disconnection, creating a warm and enveloping atmosphere, where the flame unfolds in a 180° panoramic view, as if suspended in space.

With its sleek black steel casing, cast iron interior and beige or grey brick finish options, UNI(K)4 integrates elegantly into all interior styles, from the clean contemporary to the most rustic.

More than just a decorative heating device, it becomes an object of well-being and a decorative element in its own right.
