Considering possibly replacing this with a new Contura stove. Do I have to tear everything down or is there any way to secure the chimney stack from the attic and upwards?
Hi!
It's pretty much impossible to give a 100% accurate answer without having been on site...
But at my summer place, I previously had an open fireplace with a traditional chimney. When I was going to replace it with a Morsø cast iron stove, my first thought was to run an internal pipe in the existing brick chimney.
The craftsman I hired quickly convinced me of a better plan, which was to renovate the existing chimney stack. So he rebricked the last 1.5 meters, applied some sort of internal sealing to the entire stack, and the end result was perfect. The advantage of keeping the existing stack is that it heats up every time you use the stove, which drives the moisture out and extends its lifespan significantly.
Additionally, he suggested that when I tore down the existing open fireplace, to keep the fireplace itself (the base), then place a sheet metal over it and put the stove on the metal. This raised the stove, which provides a much better close-up experience of the fire.
So... contact a good stove installer and ask for solution suggestions
Examine if the chimney stands on the wall or on the stove. Hopefully, it's the first solution. If it's the latter, the chimney must be seriously supported before dismantling the stove. A knowledgeable mason is required then, I would say.
Investigate if the chimney stands on the masonry or on the stove.
Absolutely, I forgot that "detail." I was lucky that it rested directly on the foundation below, so no issues there.
But a knowledgeable mason can surely suggest good solutions depending on how it looks
Hi!
It's almost impossible to give a 100% correct answer without being on-site ...
But at my summer house, I previously had an open fireplace with a traditional chimney. When I wanted to replace it with a Morsø cast iron stove, my first thought was to insert an internal pipe into the existing masonry chimney.
That's what I thought could be done. Just to clarify, this is the one I want:
So I want to remove everything inside. The insert has been replaced before, so the masonry chimney is standing on the whole block that is inside.
But I thought you could remove a row of bricks in the attic and frame it up so it rests on the frames instead..
Then you're approaching a point where it might be better/easier to demolish the entire chimney and install a new metal chimney.
There is a lot of mass that the attic floor has to support, probably requires a serious structural analysis, as well as approval from the fire authority. I almost think it requires fire-rated steel beams for that construction... but you'll have to check with those in charge
Now I don't quite understand. Is the chimney on the stove after all? In that case, I agree with the post above. But contact the constructor to see if it can then be solved in a simpler way.
