Where I live (Uruguay) its either galvanized steel (obviously not an option) or paying $70 per meter.
Im not about to pay $600 for the piping on my RMH when I chose to build an RMH to save money..
So what other method is there to build a cheap, yet sound piping system for my thermal mass??

IF you were to try square duct work you might have passable good luck with a 7'' x7.5'' ducting but you would have to make a continuous trench, rough and finish plaster its inside walls smooth and then lay pre-plaster'd,and finish plaster'd cap stones over your trench. This is just me talking, but that seems like a lot of work if someone would teach me how to make round pipe !
