In India, the potential of biomass as an energy resource is very large and accounts about one third of total fuel used in India. The combustion process in traditional cooking store called as chullah is a non ultimate source for cooking and favours incomplete combustion with lower thermal efficiency. The gasifier works on the principle of gasification, has low emission in comparison to traditional cook-stove. This study reveals the design, performance and evaluation of updraft Gasifier with water heater. The performance of gasifier cum heater mainly depends upon the energy needed, diameter of cylindrical reactor, fuel consumption rate. Thermal efficiency of Babul wood was found to be 19.26 %, Thermal efficiency of water heating system was found to be 27.03 per cent. This system was designed based on fuel consumption rate, dimensions of reactor. The economical evaluation was carried out based on Benefit cost ratio and Payback period and it was found to be 1.45 and 4.22, respectively.
