here’s my dressing gown gone?... It’s behind the radiator, so it remains warm! With the latest state-of-the-art radiators, (almost) anything might happen in the bathroom.

This applies to Byobu, the innovative radiator by Antrax. On the wall, it slides open and close as it’s fitted with slender heated panels that rotate on a central pivot. Inspired by traditional Japanese screens (its name in fact stands for “protection from the wind”), Byobu reinterprets a standard radiator, transcending its normal function and transforming into a dynamic, interactive object, capable of altering its structure according to your needs.

Byobu’s main features are its ground-breaking design, high thermal output, maximum convenience and functional versatility. Byobu is additionally the sole adjustable radiator in recycled aluminium on the market to be equally powered by electricity and hot water.

A revolutionary project, to say the least: illustrated to Designbest by none other than the designer himself, Marc Sadler, an internationally renowned designer – he has won 4 Compasso d’Oro awards collaborating with top Italian design firms – a pioneer in experimenting in new materials and drawing influences from a diverse range of technologies. Antrax has interviewed Marc Sadler for Designbest Magazine, this is how the designer has described this project.

What’s the source of inspiration for this project?
I was inspired by the twofold aspect of the room to which this piece is destined. On one hand, the bathroom is a functional and efficient machine, although this aspect is imperceptible and on the other, it’s a space in which you relax and take care of yourself. So I envisaged a radiator that possesses practical – it heats the room and doubles as a heated towel rack – as well as aesthetic qualities.

What are Byobu’s most distinctive features?
It’s a dynamic, versatile radiator that doubles as a home accessory. It’s composed by two parts that rotate around a central pivot and you are able to place both parts to one, either the left or the right-hand side, in order to create one sole, large panel, or in alternative you are able to stagger them to form one or multiple hooks (“momoko”, Japanese for “tiny peach”) to hang towels or dressing gowns behind the heated surface.
As regards to its technology, Byobu is extremely efficient: it rapidly reaches full power, thus reducing your energy consumption as well as ensuring a high thermal output. It’s most remarkable feature is the fact that it’s the sole portable radiator on the market to be water as well electricity-powered.

Where do the names Byobu and Momoko come from?
Literally translated as "protection from the wind", Byobu is a screen, an essential feature of traditional Japanese interior architecture. The physiognomy of our radiator with its adjustable wing-like panels, suggest this poetic license. Subsequently, Momoko, the Japanese for “small peach”, seemed to us as the perfect name for its complementary wall-mounted hook. 

Is this the first radiator you’ve designed?
I have previously designed a range of heated panels for large spaces, especially aimed at industrial use for a large-scale firm. Byobu on the contrary, is my first design for domestic use. I was instantly attracted to this topic as Atrax is a top client as well as for the fact that I found the subject extremely intriguing.

Would you like to describe your partnership with Antrax:
I affectionately describe the Crosetta brothers as "mastiffs": they are extremely well prepared, technically and commercially and have a great knowledge of the world of design, they have total control over “the product” and know exactly what they want. Our type of collaboration is perfect for a designer such as myself, who prefers a dynamic, professional relationship, defined by a lively and constant exchange of ideas and project solutions.
