If you google around, you can find regulators
with a knob for variable pressure - can go down
to about zero.
When I built my metal melting furnace, I wanted the
propane bottle to be FAR away from the 1500+ degrees!
Also needed to vary pressure to control the blast.
A variable regulator and a 15' hose works really well.
Since then I have used the same setup - hose/regulator,
not furnace! - connected to my Coleman stove when I
tent camp. No probs, heats the soup just fine.....
