I'm planning on having one chimney serve both an open fireplace and a stove. They will be back to back one, stove in kitchen/living room fireplace in sun/living room. Are there any issues with the one chimney serving both? Any design or build factors to be taken into account?
no issues.... you will obviously require two flues, so the chimney should be sized correctly. refer to the HOMEBOND house builders manual for correct details.
Is it absolutely necessary to have 2 flues sydthebeat? Is there any way of breaking into the one flue from the kitchen backing on to chimney to accommodate a stove? If two flues are necessary what is the minimum chimney width needed to accomodate 2 flues? This is a new build (bungalow) and I have decided to put in a stove in the kitchen at the last minute. The trusses are already precut (600 centres) to allow a single flue chimney pass through.
Doc J deals with flues and chimneys.
I have seen shared flues many times in older properties, where a stove in the kitchen was an after thought and a hole knocked into chimey stack. I would not recommend it. you may have draught problems and more importantly allow carbon monoixde to enter living room when stove is alight.
I think the only reason that older properties got away with it, is because they are well ventilated(draughty!) as opposed to well insulated modern homes
So all agreed that two flues are required. Next a question on the possible configuration.
If the chimney is an external gable chimney, which is flush with wall of the kitchen and is protruding into the sunroom. Is it possible to keep this configuration and have the two flues side by side instead of back to back. My wish is to keep the chimney as an external chimney and not have it protruding into the kitchen.
