Looking at all the woodburner threads here has had me thinking of one but is there a minimum height to the top of a flue for woodburmer? I have about 3m to the top of a striaght chimney-It's a single storey extension. Thanks in advance.
Have a look at the building regs document. Moew of an issue is where the flue comes out - there needs to be a decent airflow around it so there are rules relating to positioning in relation to roofs etc.
