Thanks!
We have many chimneys... On the roof, the one on the left is for the RMH. It is maybe 1 meter of stone and then 3 meter of black pipe.
On the roof, the one on the right is for our kitchen stove, it is only stone. Draft is a lot worse with that one, the kitchen stove needs careful lighting..
Then the one closest to the RMH is the chimney from the downstairs (future) workshop. Also part stone and pipe
And the stainless steel one is fromnour diesel central heating.
Maybe one day i will make another one at the back of the house so we can geat with wood there too. Never can have enough chimneys
