	Group 13 dissected a kerosene torpedo heater to apply reverse engineering processes. For the dissection we recorded, in detail, both the disassembly and reassembly processes, in a stepwise fashion including detailed pictures of parts and assemblies. When the heater was dissected, we analyzed the major components to see how manufactured and what materials were used. We discussed the engineering choices for the parts, analyzing the advantages and disadvantages of the parts design and construction methods. Several recommendations were also made, biased on our testing and dissection of the heater, to improve the heaters design.

		+	==Introduction==
		+	The heater dissected by group 13 is a portable unit that burns kerosene and is intended for use in shops or other work environments. It includes features such as a thermostat and safety checks.

-* We were unable to test are product due to the fact that the gas tank contains a large amount of kitty litter in it. We did not want to risk damaging the heater by running it in its current condition.
+* The heater appears to work well, it ignites easily and the thermostat features are functioning.  The heat output also appears to be sufficient however the testing was not preformed at the cold temperatures the heater would likely be used.
-** We plan to dissemble the gas tank and thoroughly clean it when we approach our disassembly phase, before disassembling the actual heating unit we will reattach the gas tank and run the product.
 * Overall the concept of heater is not very complex; it is basically a system containing a controlled flame in a tube where air and fuel are fed.  The heater is just a well controlled fire.

 **. The advantages our product has over its completion is a 10,00 BTU/hr advantage over Master’s product and the wheel and handle kit is sold separately for DURAHEAT’s product. Every other aspect is matched or beaten by competitors.
 ** The disadvantages our product has are fuel consumption, fuel tank size and max outlet air temperature. Our product consumes 1.6 gal/hr while DURAHEAT and Master’s consume 1.3 gal/hr and 1.4 gal/hr respectively. Our products fuel tank size is 13.0 gal while Master and Mr. Heater both have a 13.5 gal tank. Lastly our products max outlet air temperature is 1,165° F while Mr. Heater’s is a much larger 1,450° F.
