They both do the same job so whichever option looks aesthetically pleasing

Thanks. I’ve come to a similar decision

I haven’t bought the stove yet as I need to re-tile the hearth first. The manufacturer (Ecosy 5kw) of the stove I’m after said there shouldn’t be any problems as long as the size increases, which it does. The liner is about 5 years old and still looks pretty good nik albeit a bit sooty, but I’ll get it swept before use. I had read somewhere that you shouldn’t increase in size by more than 2" or you may get adverse effects on the stove operation or the draw, that’s really why I’m asking. Thanks both, Robert

Hi, I have a medieval cottage in Devon with an inglenook fireplace. I have just removed a Franklin Stove which was old and juicy on the wood and am replacing with a new wood burner. The Franklin used an 8" flue, stove pipe to the register plate, then approx 18' of flexible 8" straight up to the top. The new stove has a 5" flue. My questions are as follows: should I a) join a piece of 5" stove pipe from the new stove using an adaptor to the existing 8" flexible flue at the register plate or b) drop a new flexible 5" flue down the 8" and connect the two 5" is 5" increasing to 8" too much of a increase? Will it compromise the stove operation/ performance? Does a smaller flue give a better draw? If I go with option b) will one flue within another cause any problems? Thanks in anticipation Robert
