I agree that for the most part, Citroen indeed knew best, but i find that the standard heater tubes are a massive pain in the ass to fit, are a real fire hazard being cardboard and so close to the exhaust and for one of the tubes my handbrake rubs it on the bottom and the heater control rubs on the top, causing them to wear out very quickly and making the heater controls difficult to move. All of the above combined are enough to make me at least investigate alternatives that didn't exist when the 2cv was created. The only tubes I've seen set alight, weren't properly mounted and as a result, had fallen onto the exhaust. Before fitting the tubes, compress them as far as possible before cutting them to length (if at all necessary) usually they fit without cutting. This way the tubes will never fall off, if you still don't trust it, just use some tie-raps to mount them on the adjuster cable and the flat metal strip near the handbrake. For the places that get rubbed trough, you could maybe tape or glue a metal plate onto the tube. The foam inside in the original tubing is essential in absorbing part of the noise.

 Re: Heater Tube Alternatives?
Somebody suggested running a wire through the middle screwed to the heat exchanger and heater duct which will stop it coming off.

 Re: Heater Tube Alternatives?
I put old vacuum pipe up the inside of originals to stop them collapsing internally but also killing the noise, I also have two computer fans in the bulkhead inlets to blow some air over the screen initially..

 Re: Heater Tube Alternatives?
Well, I managed to line the new neoprene hoses last night. Small ones with a length of hollowed out swimming woggle and the big ones with some high temp spray adhesive and some packaging foam sheet. First test show the air flow is amazing, judging by the amount of crap that blew out of the window vents. Full test tonight!
