However, the conventional coal pot does not correctly support the use of pelletized sawdust as a possible replacement fuel for charcoal. Therefore, the aim of this research was to develop a new and efficient biomass stove that utilized pelletized sawdust as its fuel. The improved biomass stove was designed and constructed, and its performance was tested using water boiling test (WBT 4.1.2). The performance of the biomass stove was compared with that of conventional coal pot. In addition, a checklist was developed to ascertain the economic and environmental potential of biomass stove. The results obtained in the study indicated that there was a better performance of the improved biomass stove with a boiling point of 9 min, a burning rate of 0.09 kg/h, and a thermal efficiency of 35.5%, comparable to the boiling point of 30 min, burning rate of 0.13 kg/h, and thermal efficiency of 18% of the conventional coal stove. 80–100% of the users affirmed that the new improved biomass stove is cost-efficient, the most effective way of doing cooking, an inexpensive fuel source, and the most convenient.
