MAPP Gas or Propane? Which burns hotter? Searching the internet will return all kinds of speculation about the two fuels, still leaving you/us scratching heads. The Home Depot #sponsored sent us the Bernzomatic TS8000 Torch with a can of MAP/Pro fuel. We thought that we'd end the confusion, or some of it, by testing the MAP/Pro and the Propane.

First of all, MAPP gas is not available any longer. The new fuel in the yellow bottle is now called MAP/Pro, which is just Propylene. Word on the streets has always been that MAPP (or MAP/Pro) burns hotter than propane, so you want MAPP gas. We wanted to see for ourselves, and then bring the data to you.

We used our Bernzomatic TS8000 Torch with the MAP/Pro fuel, then we used a Propane tank with an older Bernzomatic broader tip. With a piece of 1/4" thick steel bar stock in the vice, we used each torch for 30 seconds to heat up the steel. Then we used our thermal imager to check the temps. In between torches, we quenched and cooled the steel back to ~85F. After the 30-second round, we did a 60 round as well.

Results:
Propane: 158F (30s) . 254F (60s) . 418F (60s w/TS8000 tip)
MAP/Pro: 257F (30s) . 402F (60s)

Those were pretty big differentials in temperature between the Propane and MAP/Pro, and I knew the geometry of the tips were much different. We then decided to switch the Bernzomatic TS8000 tip to the Propane cylinder and test again. The results were much different, after 60 seconds, the Propane with the TS8000 tip produced 418F. This is "hotter" than the MAP/Pro, but we're going to call this even.

Our conclusion is the tip geometry and efficiency has more to do with the heat than the difference in the fuels (MAP/Pro and Propane). Looking down the throat of the TS8000, you will see a brass swirl ring, and the holes at the bottom of the tip allow much more air/oxygen in to help fuel the flame. The Bernzomatic TS8000 also allows you to ignite the fuel by just pulling the trigger. Let off the trigger and the fuel stops and the flame extinguishes. There's also a continuous flame button that you depress after the flame is ignited. This allows hands-free soldering, brazing, etc.

You can get the TS8000 Torch kit for about $42 from the Home Depot. MAP/Pro fuel cylinders run about $12 each, while the propane only costs about $4 each.
