Demand regulator jibes with Meter, The All States meters the propane flow as needed. Demand regulator sounds like the same thing to me. Meters the flow is how Lyle explained it to me.

Good.

Paul just mentioned his Smith rosebud puts out that kinda heat.
Perhaps the AS heat output isn't all that novel?
If, as Jim says, the propane specific difference in the Harris/AS
lies in the LP designed mixer, and not in the torch body..
Then the LP mixers on all modern torches ought to be quite similar. No?

Rev?

Yeah; I just judged you worthy;. You'll have to print up your own diploma.
Mine is left over from the 60s.

You hear a lot of marketing jazz that doesn't really stand up, for example, saying your furnace burner puts out 100,000BTU doesn't mean anything unless it's 100,000BTUs/hr.  Of course I may have just missed it, I haven't been following the thread very closely. I've been waiting for the BONANZA!! to jump in. <grin>

I know I can crank my propane forge to melt the fire brick liner hot and keep it there for 6-7 hrs on less than 2 gl. of propane and that's running atmospheric air, not oxy. The hard fire brick I use is 3,000f+ working temp and I can melt it in my forge. My rose bud will slag it in a few seconds, the surface ripply, glassy and being blown around by the flame while the the heat hasn't penetrated 1/2".
