Why? What is the reason for this, do you mind sharing your thoughts?
Never have two appliances in same flue.
It very likely could work better. Easier to heat the pipe initially and keep it heated so it can drive the stove. 6" pipe should be plenty for a well-made stove, unless it is ridiculously huge. Check the instructions, make sure they are relatively current or contact manufacturer for current info. A nice, straight, long shot of packed 6" pipe should make a very powerful chimney to drive the appliance, I would need very convincing evidence that it NOT OK before I let someone tell me 'you can't do that.' If you got CSST liner pipe or lots of bends, do more homework first. Also consider the headloss caused by the rain hat and maybe choose one with the 'venturi eductor' feature if they still exist.....or just add a couple feet to get more draft.
I heat with two Vermont Castings Defiant Encores and have one on an 8" flue and one on a 6" flue. This model stove came with either flu size and both work well. I would try the 6" pipe you have, but if the stove is current production the manufacturer (if it is not in China) can tell you what will work best and what is acceptable. A lot depends on the stove, but it is certainly worth a try.
Good advice. There's an interesting guy who makes his own insulated piping who goes by "Honey Do". Good stove and chimney pipe are expensive, so I'm trying to figure out if I can replicate his stuff and if it makes sense to do so. He's into "Rocket" stoves, too. Claims virtually no creosote left over.
I've read that, too. Overload the flue?, I guess, but I wouldn't run them simultaneously.
Mine is, too.
Just a stupid setup. Your Insurance co will cancel policy and/or not pay a cent if you have a fire
