Not a professional but have done the following-
I built a chimney an fitted my own wood burner. It was built when i converted our house from a chapel. This was 20 years ago and before regs applied to this.
Now I think people tend to site them on an outside wall and just put the pipe on the outside of the house. No reason why you cannot go directly upwards throught the floor and room above and roof. Lots of heat in the flue.
Ours is purely to heat the room, not linked to the central heating. I dont think it really is a constant source of heat and reliable enough to use for hot water. With thermostats on each rad our heating just shuts down where the wood stove heats so it is a good balance. Central heating is much more complicated these days and not well set to work from a wood fire.
Financially, they are expensive to run if you get in ready-cut logs. I cut split and get all my own logs, and you do need a lot! If you are reasonably fit and healthy it is not much work to cut and split logs. About an hour to turn enough tree into a weeks firewood (a builders barrow full lasts about three days when cold or a week when mild). I am running this winter on felled trees from our garden but do rummage around and "find" wood. Depends on were you are and if neighbours will put up with you and a chainsaw on a sunday morning. Try to get a year ahead on wood and store it to dry and mature. So big shed needed for storage!
If you get one, make sure it is a decent size and will take good size logs and enough to last overnight, ours can burn non-stop sometimes for three weeks before I need to let it go out an to empty the ash. Small ones need small logs (more work) and dont hold enough to last all night .
