Abstract

David and Emily travelled to Pondicherry India to design a space heater and water heater using the waste heat of a rocket stove chimney designed by the Prakti Design Lab. This project was to benefit people who live in cold climates with no means of heating space, except for use with the rocket stove and little means of heating water for simple tasks such as washing clothes. The space and water heater were prototyped and conducted water boiling tests to see effectiveness of the systems. The space heater and water heater held an average exhaust temperature of around 182 and over 200 degrees Celsius respectively, concluding that more energy may be potentially accessible with some adjustments to the design. The water heater was able to boil approximately 4.5 liters of water in about 25 minutes on average, often boiling two to three times faster than the pots directly on the stove. This provided a good method of obtaining usable warm or hot water within short intervals, while still having the capability of the stove. Given these results, more testing and research can help the impact be better defined and quantified for obtaining a more optimal design, marketing, and production.
