Interestingly, the modern way to do it is to have one regulator for

That is correct - the OP is wrong, for the same flame size butane
will be the hotter.


Not me .. saying it is hotter .. just what is posted on many sites ...

You are mis-reading it quote..
'A given quantity of butane will burn hotter than propane but in fact
propane regulators release the gas at a higher rate to compensate.'

As I said, butane burns hotter than propane.

The above mentions a given quantity, which also agrees with what I said
about butane providing better value heat per £ spent.
