Project Construction
The image to the left shows the testing of the "Mock Up" On Demand Water Heater. The mock up was built as a proof of concept. Since the testing was successful (the device was capable of raising 55°F water to 185°F at a 0.5 GPM flow rate), the material for the final device was ordered and construction commenced.
The video shows the CNC plasma cutter at Central Washington University cutting out the pattern for the final On Demand Water Heater. The plans were built in Solid Works and converted to a DXF file. This file was uploaded to the cutter. The cutter cut the pieces to within +/- 1/32" from the design.
On the left is an image of the finished device mounted to the companion Adjustable Beer Rack System. There were many changes made to the final device based on design practices that were found during the construction of the "Mock Up" device. The material was changed to stainless steel due to the excessive amount of condensation generated during the process. Also, all seams were welded (instead of tacked). to minimize unaccounted for exhaust. By making these changes, the physical appearance improved as well as system efficiency.
