I was away yesterday with my better half to see about buying and installing a woodburner into a single storey extension thats built onto my house ,anyway i thought there would be nothing simpler pick a stove a couple of meter of flue and install but i was told building regs say there has to be a minimum of 4.5 metres of flue on top of the stove to get the propper draw and so there would be no carbon monoxide coming into the house :yikes: i thought is this correct so i went to another stove supplier and was told the same , so basically if i went ahead the flue pipe would need to be higher than the original building but the flue would need to be unsupported due to the position of where i would want the stove(ie it would not be next to the original wall) .the flue pipe itself would be £2000:yikes: anyway this led me to think about the stove i have for my tipi n shed there is nowhere near 4.5 mteres on top so are they safe .....
