Good choice. Now come the more tricky decisions. IMO, use 904 grade liner (or Selkirk twin wall if freestanding chimney), it’s worth the extra to ensure you won’t have to replace. Use a Vedette cowl, which is anti-downdraft. They are not the most attractive things in the world but are the best I’ve used. I’ve got one on a Rayburn 345W / Selkirk and it pulls like a train even in the worst wind conditions. Far better than anything else I’ve tried. I’ve bought liner and cowl stuff from fluesystems, very good quality and price.
Finally, the wood. Get yourself a moisture meter. Don’t burn anything higher than 20% moisture content. If you are buying it in, find a good supplier and test the moisture content before taking delivery. If they are selling as seasoned firewood, anything more than 20%, send it back. I burn about 6T a year but have my own land. This winter I’ll be burning stuff I coppiced 3 years ago, stacked and seasoned in a barn. Not too fussed about the wood type (although ash is the best), moisture content is the most important factor. Have a read of Norwegian Wood by Lars Mytting, will tell you all you need to know when it comes to wood!
