Having used both for a number of boilers, I wouldn't bother with propane for
anything over (say) a Gauge 1 boiler. Too much foolin' around on a large
job. With oxy/acet you can localise the heat much more effectively. Copper
ain't as easy to burn out as a lot of people think - especially if your
plates are thick enough to comply with AMBSC code, the main danger is the
tube ends.
