I'm a big fan of gas fired, instant on instant off and flame control via the regulator. Rims and Herms are just a bit too exotic for my building and wiring skills. But thats just me, YMMV. I would tend to go with the system that requires the least investment or repurchasing of components. Just sayin......
What do you mean "no Kidneys"???, WTF now I gotta drink less beer...
Join the Automation sub forum in Electric brewing for a discussion of components and control systems. I did!!!!
