"What is the output in BTUs of the blichman and the bayou classic unit?
The bayou classic shows 55000 btu. I think they have a real killer unit with much higher btu output.
The blichman shows 72000 btus
but i still think tha bayou classic makes something inthe 135000 btu area. I cant find it now."

The difference in btu's is determined by the pressure control valve. The Blichmann has a low pressure valve and the Bayou has a high pressure valve. You can change the valves out on either one. Blichmann used to sell their units with a high pressure valve but found that it was just as effective with a low pressure valve and used less gas. Also you are less likely to melt the diffusion plate with the low pressure valve, you still could but it's less likely.

So you are saying that it produced the same heat /btus and used less gas? That doesnt seem possible unless the metering device was originally junk????

With the low pressure valve it uses less gas but produces less BTU's. The real question is how many BTU's do you need to heat a boiler efficently. I can heat 6 gallons in 30 minutes and get 6 to 8 runs from a 5 gallon tank useing the low pressure valve.
The new Bayou burner also uses a low pressure valve it also has a smaller burner than the Blichmann that's why they have a lower BTU out put. They also have a high pressure valve and a larger burner that increases the BTU out put in their Bayou Banjo as you mentioned.
The reason both Blichmann and Bayou started offering low pressure valves is that some people just cranked the burners up all the way and were burning/melting the bottoms of their pots.
It takes a little time to learn how best to adjust your burner for highest heat with best gas efficiency.

I have several valve's I've saved from old bbq's. Would those be better than what's on the Bayou? I like the 4' hose that comes with the Bayou though. I imagine that can be changed out as well?

My local propane supply store will make any custom configuration I want. Most supply stores that sell tanks and propane will do the same. Here is a website that has an adjustable valve so you know what to look for, it's rated from zero to 200,000 BTU's. That's enough flow to run a small forge/smelter. I don't think the Bayou Classic is rated for that high of heat. http://propanewarehouse....adjustableregulators.asp BTW 10 PSI is a low pressure valve.

I'll take a look at the site. I'm not that close to a city large enough to have a propane supply dealership. All that's available to me is a local guy that fills large tanks awa smaller tanks. Next time I'm there I'll ask about a low-pressure regulator. This may solve my problem. Thanks again.
