08. Stove analysis methodology

Analysis of a stove may focus on several areas of interest (see stove design for a list of possible considerations for stove designers and users).

More information about the methodologies used by the project will be posted here.

Stove performance

Water boiling test
The main aim of this test is fuel efficiency, and allows a comparison between different stoves tested under similar conditions. Standard methodologies are available (references), but in the case for Asia, 2.5l of water rather than 5l of water are used for the test.

Kitchen performance test
This is a 7 day test, where the total fuel used by the cook is recorded.

Controlled cooking test
Exactly the same meal is cooked by the same cook in the same conditions (lab or field test).

Emissions analysis

The above tests can also be carried out with air quality monitoring equipment which typically measure particulates and carbon monoxide.

Long term considerations

An important factor for stove users may be the durability of the stove under normal use conditions for example. This information can be only gathered in long-term projects.

Socio-economic factors

In order to analyse the stove, other factors need to be considered including prestige or other socio-cultural concerns. This information can be gathered by questionnaires, or by workshops. Women can be targeted specifically to gather information on some of these issues, since they are likely to be the main stove users.

Market analysis

Analysis of the commercial success of a stove can give an indication of the ability of the stove to successfully provide for the needs of the local community. Analysis of the rate of uptake and price setting can also be useful information.

Many projects work with different models for dissemination, including indirect subsidies for stove development and promotion or direct subsidies which have to be taken into account when considering market information.
