At the moment we have a gas back boiler,it's 16 year old .We are thinking of taking it out and fitting a combi in another room .The back boiler has a 4" flue liner ,would we be able to fit a log /muiltifuel stove to this liner ?.

hi sooty

if what you have now is just a gas flue liner then the walls of it wont take the heat they are used

to take fumes away

the soot and tars are very corrosive and will rot a gas flue liner in less than a year seen it happen you require a stainless liner a good supplier is a company called fluestox there on the web

Certainly not! but depending on the condition of the chimney you may not need a liner.

Give these guys a call, first class advice & service. I purchased my stove 5 years ago for a bargain price of £180 new and it's still going strong, after being used every night during the colder months for five years.

Thanks for all the replies,the existing chimney is a five inch clay pipe. We know this leaks ,so we would need a liner in it , would this be big enough to get a solid fuel liner down ?.Just about to look at "stoves " & "fluestox " on the internet . :blink:

Hi,

 

 

I thought that woodburners had a min of 6" flue but I could be wrong.

You can purchase a 5" flexible liner but would have to measure the OD to see if it would fit your existing clay pipe.

That would connect to a 5" to 6" converter, which in turn would connect through the register plate to a 6" pipe on to the stove.

 

Flex liners will cost about £60 per meter and it's worth getting the best, because it's hassle to replace. Some come with a 10 year, some a 25 year guarantee. I have seen them with a 35 year guarantee but as with most guarantee's it's not worth the paper it's written on.

I didn't think you could use a smaller flue than the output from the stove i.e a reducer.

if that is internal diameter then I don't think you can fit one as the 5" has an internal diameter of that. If it is clay pipe then how do you know it leaks as that is usually used as a form of chimney liner. When was the house built?

The pipe is 5"internal, or so we were told when it was tested with a smoke bomb,in1993.We were going to fit a multifuel stove in 19993 which would have done heating & hot water ,thats when we had to change plan and fit a gas back boiler .We just got thinking maybe we could fit a smaller stove , just for room heat only ,maybe with a 4 "flue .
