Manufacturing/Building Method

Stoves are mass manufactured in InStove's core factory in Cottage Grove, Oregon in the USA. For 2018, 20 stoves/day are built with negotiations to increase its production. InStove is opening building factories in target regions while exporting stove components and needed production methods from Oregon. Named as the Stove-Factory-in-a-Box production strategy, the first factory was opened in Afikpo in Nigeria in 2013 and exceeds the production of 10,000 units. Negotiations are on-going to open factories in Kenya, Ethiopia, Uganda, Ghana, and Haiti.

Production methodology relies on laser-cut critical parts and custom tooling. Critical components are pre-manufactured in Oregon so that most of the assembly can be done by semi-skilled trained workers with hand tools with low power requirements.

Academic Research and References

Compliance with regulations

International Organization for Standardization/Volunteers in Technical Assistance (ISO/VITA) performance standards for the Water Boiling Tests (WBT), a laboratory-based test that can be used to measure how efficiently a stove uses fuel to heat water in a cooking pot and the quantity of emissions produced while cooking. In WBT Tier 0 is the lowest performance level, and Tier 4 the highest. A stove belongs to a Tier if all of its performance indicators meet the criteria for that Tier.

Test results prove that stoves are “Tier 4” in 9 out of 10 categories, and “Tier 3” in the remaining category.
