I built a 1BBL system almost exactly as you described. I use 200K BTU jet burners with Honeywell electronic ignition and Auber Instruments PID's. The control panel is a gas modification of the panel featured at The Electric Brewery. I have 35 gal Blichmann Boilermaker's for the MLT and HLT with a 55 gal for the Boil Kettle. To heat water faster I just plumbed a hot water supply line from my home hot water heater. It only takes around 30 minutes to heat the 125 degree hot water to 155-170 degrees. To "soften" the direct fired MLT, I raised the MLT off of the frame 3 inches to reduce the heat. I have had no scorching problems after 4 batches. In addition I can heat the 150-165 wort to boil in my kettle in around 40-50 minutes, but I ignite the burner early in the sparge cycle to expedite the process. Finally, I fuel the system with tandem 40lb LP tanks plumbed in series. After 4 batches the tanks are only about half to 2/3 empty. As far as electric is concerned, you would have issues as well as it would likely take 50 plus amps to feed the multiple 5-6K watt elements required to heat such volumes. I calculated the feasibility of going electric, and the heating times were very similar with common residential elements. I cant remember the specific amp requirements, but it was large. You would need industrial elements, and 230-440 service to really shorten the time. I have attached pictures of my build for your review.

any suggestions on a type of 1/8" bit that doesn't take forever to drill through 1/4" steel plates? Yes 1/4"... that was not to my specs
