CONTINUAL EVOLUTION!
Back to electric. Problem solved. I bought a flexible silicon rubber heater and RTV'd it to a keg. It took 2 hours to hit boil, but I can safely tripple the wattage to 21 watt per in^2. I'm in the process of getting a quote to have a full jacket made and hot vulcanized to a kettle. It is simply a micro-steam jacket replacement. Think of a electric blanket that is glued to a keg.
With this last minute change, I'm moving to a single tier electric system. No turning back. I just ordered the stainless today.
