I just installed one into my home that I just built. Ended up with a hearthstone Shelburne.
I've used it 4 or so times already this year including last night. It's advertised to heats up to 1800 I can guarantee you it heats my 1600 just fine.
I built all my chimney etc myself. There is actually not a lot of technical YouTube videos on the manufactures chimney pipe I installed. Once you penetrate a wall or ceiling you've got to use double walled insulated pipe. Let me tell you cha ching. That stuff is pricey I went through the wall behind the fireplace then ran up the exterior wall. There is also a T that youve got to install for cleaning purposes if you take that route. Think the t alone was 350.
If you're buying new just make sure the place you're buying from knows what they are selling and are knowledgeable. I got stumped a few times and had to call those guys for some free technical assistance. I don't know where you are located but I highly recommend north Texas chimney in Krum. I highly recommend you stay away from the place in Allen tx.
Also those things are heavy. Like really really heavy, with no place to grab them. I got my brother and my nephew to help and used straps and 2 x 4s and it was all we could do.
Ps also there is a formula you can find online that shows your minimum chimney height. Has to do with the pitch of your roof so know that. Or if you buy from someone they should be able to tell you the height but again know your roof pitch.
