Just bought one of Machine Mart's (Clarke) 'Little Devil' fan-assisted 
propane heaters for my garage/workshop - and boy, does it chuck out some 
heat!

I have two sources of propane at my disposal - a couple of red propane 
bottles (6Kg) intended for caravan use, and a larger (13Kg) bottle of 'patio 
gas' acquired with a patio heater which SWMBO insisted on buying a couple of 
years ago, and which has been used only once - so the bottle is almost full.

I had hoped to be able to use both sources with the Little Devil, as I have 
regulators with both type of fitting and assumed that I would be able to 
swap the Little Devil's pipe from one to the other. But no - for a start the 
pressure is quite different. Caravans and patio heaters run at 37 mBar 
whereas the Little Devil runs at 0.3 Bar (300 mBar). In addition, its rubber 
hose has swaged threaded connections both ends rather than simply pushing 
onto the regulator's fluted outlet pipe.

The regulator supplied with the Little Devil has the usual left-hand 
threaded propane inlet connection, which fits the caravan bottles without a 
problem. But I don't have a way of using the patio gas bottle - which uses a 
(27mm cylindrical) quick-fit connection similar to the 21mm jobby on many 
caravan butane bottles. Any ideas for solving this? It seems to me that I 
would need either an adapter with a 27mm input and an output female 
left-hand thread to take a conventional propane regulator, or a 'high 
pressure' regulator which would fit directly onto the patio gas bottle and 
which has a threaded outlet to take the Little Devil's pipe. Does either 
exist and, if so, where can I find it? Any alternative ideas?

TIA.
