My first floor is almost entirely gutted and we are planning significant changes to the house. One of which is a wood cook stove in the kitchen. I have found a UL listed model that does all the things I want and even has a rear vent. I've been reading around the forums and have seen Ventis and Excel as being the top players for a chimney. My plan is to rear vent the cook stove right through the wall into a T and then up the side of the house. I don't have any roof overhangs to deal with so it should all be fairly straight forward and easy as far as a chimney install goes. I currently have a scaffolding tower as well. Anything I should know before contacting dealers and getting pricing for chimney? Since this will be an exterior chimney I want the most insulated class A pipe I can find. Second on my list of priorities is ease of install and cleaning. My wife and I have been talking about putting a chase around the chimney, but we really don't like the idea. Recently I saw a thread here, https://www.hearth.com/talk/threads/clever-german-chimney-tee-with-cleanout.175343/ , that talks about a really neat T with a door that would make my life way easier. So far it doesn't seem like anyone has experience with this product. I'm considering being a guinea pig. I suspect this coming winter I'll have far more cold starts with running two wood appliances and want to put a good liner inside of my masonry chimney for my Morso and use double wall connector pipe with two 45's. Insulation for the liner seems less significant in this application with an interior chimney since the house is insulated already. However, I'm no expert or professional, so I welcome any advice for this. It seems like the most straightforward method is to use a rope and pull a liner through the chimney. There is a clean out door on the bottom if that helps. I'm all ears for this venture as well.
