If wood burners are going to be banned, which I think is unlikely, my suggested route would be to get a pellet burner. Pellets are a cheap and efficient way to heat. Like any wood burner you still need to ash out every day.
They are easy enough to install and most have a relatively small flue so bits are easily handled and fit together to form an airtight seal.
The easiest flue installation is to rise up from the heater, turn 90deg and go through the outside wall with a small terminal on the outside.
I have never seen one that uses an existing chimney but I don't see why that can't be done. You will need a proper terminal for the top that also caps off the existing flue. The manual will tell you the maximum flue length and most likely illustrate some flue options.
You could go on the internet and download a manual just for ideas.
