How can I get a better boil I have a 2x5 flat pan with one divider best I can get is 15 gph seems like a lot of heat is going out the stack looks like a torch arch has archboard and bricked also has auf just can't seem to get a hard boil

How much space under the pan? You need to restrict the area after the firebox to force the heat up to the pan.

15 GPH? And your problem is?

Have about a 4 inch space after the fire box using dry pine slab wood split small

15gph out of a barell?..Whats the problem. I am getting 4gph with one thats insulated and firebricked. Have made 2 gallons of syrup so far.

how deep are you running the sap? 15gph on a 2x5 flat pan sounds pretty good to me. And do you mean oil tank or oil drum? Sounds like an oil tank. (not a 55 gallon drum)

You might need to force the fire up into the pan - and make the fire box smaller. How think is the pan material?

I can get 15gph on a 2 x 3 flat pan, you should be doing better. How deep is your arch under the pan? You want to make sure that you keep the heat & flames up against the bottom of the pan.
