PostSubject: PVC chimney pipe   Wed Apr 30, 2014 9:42 am

I have read that some high efficiency condensing natural gas furnaces use PVC pipe as a chimney.   Of course in such a natural gas stove there is no creosote condensation in the chimney.   These high efficiency gas furnaces extract most of the heat before the exhaust enters the chimney.  My question is could a rocket heater burn so cleanly that PVC pipe could be also used for the chimney ?  Maybe not use PVC in the entire chimney, but in the upper portion to increase natural draft ?

The location I want to use to place my hydronic rocket heater is under some tall trees.  I am concerned about the chimney draft.   I don't want to use a chimney fan.  The stainless chimney pipe is too costly for me to use much of it.

yes a pvc pipe could be used with a rocket burner however the flue temp must be below a certain f for this to happen
however i am aware of a pvc pipe that takes a higher f temp than the normal pvc pipe and i think this is the pipe they use for extraction of flue gases

here the link for pvc softening temps where pvc pipe distorts due to tempereature

if you noticed ( pp ) polypipe used for soil stacks and sink drains this is why the pipe bows when not supported by clips at intervals

That's what I thought. I would use stainless near the heat, then the PVC to gain some extra height.
