10-20 years for a well-built metal rocket stove cooker, shorter than a full rocket mass heater given lighter-gauge materials typical of a portable cooker

Regulation (FR example)
Flue installation follows DTU 24.1. Chimney sweeping is compulsory (typically once or twice a year) under the departmental sanitary regulation, and insurers generally require proof. Some communes restrict wood burning under an air-quality plan.
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
