FirePipe™ installation kit, designed for emergency living
FirePipe is an emergency stove designed to provide reliable heat and cooking capability in crisis situations. The system is based on laser-cut flat steel sheets that store efficiently, ship in higher quantities, and fold intuitively during assembly.
Developed in collaboration with Cut & Fold, Fjaryl developed the Installation Kit that enables safe use of the FirePipe stove in real homes and emergency environments. The installation kit - a stand, wall fitting, metal straps, accessories and reinforced chimney joints - is engineered to perform under real-world conditions.
We designed the system for structural strength against wind and weather, safe installation through higher-level windows, controlled distances between hot chimney segments and surrounding walls, and a functional stove height for cooking.
The FirePipe system supports emergency safety nets in a world shaped by increasing climate and geopolitical instability. Pilot tests are currently underway in the Nordics, Ukraine, and Germany, with positive reception from local media and humanitarian organisations, including the UN.
What we did:
Product assessment and technical analysis
Usability studies and spatial mock-ups
Iterative design development and refinement
Prototyping with metal, cardboard, 3D prints, and wood
Design for manufacture using laser-cut flat sheet steel optimised for EU pallet transport
Support for assembly and installation documentation

Designed for manufacture, all components—including the stand, heat shields, wall fitting, foldable tools, and straps—fit on a single standard EU pallet. The flat parts fold into three-dimensional components during assembly, with laser-cut tolerances and features tailored for hand and finger bending.
Working through prototypes at increasing levels of fidelity accelerates learning, reduces development risk, and shortens timelines, enabling more efficient iterations and better-informed design decisions.
The installation kit supports a fire-safe chimney passage using a dedicated wall fitting. The fitting separates the 500 °C chimney from the wooden board through an air gap that reduces heat transfer to surrounding materials.
The stand positions the stove at a practical height for cooking and loading and includes:
Symmetrical geometry with no left/right parts to reduce cognitive load
Cross bars for increased horizontal stability
Tabs designed for tool-free finger bending
Secure attachment to the existing stove
Feet designed to be anchored with screws or weighted with bricks, counterbalancing the exterior chimney length and improve stability in wind and fall protection in apartment windows
