This test was done with the interest of boil in mind. I wanted to know how quick I could reach a boil after mash out.  I ran the test using a low pressure jet burner at .5 psi and a high pressure Banjo burner at 10 psi. Both propane burners were ran fully open and had their own propane source.

Two very similar stainless converted kegs (kettles) containing 6.5 gallons each were used.  I started this test at 166 on both kettles. Altitude for my testing location was around 980 feet.  I monitored the temperature of both kettles using a laptop, BCS460 , and two temperature probes.

When I made this video, I broke it into several  different segmants. Excuse the redundancy in advance!

Without spoiling the results from the video,  it is my opinion that the high pressure Banjo burner would make a great burner for your boil kettle or possibly your hot liquor tank. It is a little hot to be controlling your mash tun and takes adjusting if you want to reduce the heat.  After around twelve and a half minutes, the Banjo burner had the Jet burner by around seventeen degrees.
