I wanted to post a quick thread on the Blichmann floor burner I've used 3x now. Granted I have nothing to compare it to but this thing is great. Brings 5 gallons to boil very quickly, when I've done 3 gallon boils its incredibly fast even though I only have the regulator open slightly.
After 3 60 minute boils my 20 pound propane tank is half empty, a real fuel sipper. During boils the regulator is only opened a couple of turns and it maintains a steady rolling boil. Solid construction and nice looking.
