01 — Overview

Get the most
out of every log

Zuka is a two-burner cookstove that maximises the use of firewood — clean, efficient heat from a rocket-type combustion chamber.

The identity comes from two materials in conversation: steel and wood. Metal reads as the technology and draws the line of the design; the pine is the everyday material that brings warmth to the whole. It's a versatile kitchen that adapts to different households, where the design lives alongside the everyday as one piece — quietly raising the quality of daily cooking.

Zuka was a nine-person team project under Cátedra Rondina at FADU (UBA) — with Camila Piantanida, Federico Kakazu, Maximiliano Schivo, Florencia Di Salvo, Lucila Leone, Alejandra Fernández, Sofía Piazza and Juan Policastro — taken from Rhino models through hand fabrication to a working stove that cooked eggs, burgers and stew in the field.

02 — How it works

Rocket combustion,
regulated air

A rocket-type combustion chamber burns wood hot and clean: air is drawn through a controlled intake into an insulated vertical chamber, so the fire reaches high temperature and combusts more completely — more heat, less smoke, less wood.

A regulable O₂ intake lets the cook tune the burn; glass-wool insulation keeps the heat where it's wanted; and the hot gases sweep beneath the two cooktop plates before leaving through the flue (salida de tiraje).

03 — From CAD to weld

Modelled,
then made by hand

Modelled in Rhino, then cut, bent, welded and finished by the team — the chimney, combustion box, sheet-metal ash pan and the branded pine cladding all fabricated from scratch.
