Thank you!What a beautiful job you did--looking great--stove is different and beautiful...clancey
Yes opening up some passive ventilation into that room from the stairway will probably help.
At first my reaction to running warm air ducts through the chimney was Noooo but then I remembered your house is made of stone so it probably won't burn down no matter what you do. It is common around here to install a floor grate in the ceiling above the stove to let some warm air into the room above. What you are proposing sounds like it would have a similar effect so long as the ducts do not interfere with the liner or vice versa.
Generally, when we have an open fireplace chimney with a liner going up it we would install an insulated "block off plate" to keep the warm air generated by the stove from rising up the open chimney and project into the room instead.
60mm is pretty small for a passive duct. A small fan or blower would help move some air through that pipe.Thanks yes, all stone/brick.
The floors are reinforced concrete and add to that we have underfloor electric heating embedded into it, so no holes can be made in the floors. Wondering why we don't use the heating in the bedroom probably crossed your mind. Just a freezing area and that zone uses more than 2000watts per hour so is a significant cost. Takes at least 3 hours to heat up that floor with wood laminate floors on top of the concrete so rarely do we use it.
I have a closure plate ("block off plate") above the stove to prevent heat loss and the fan to blow it out of the insert. Could do with a bit more insulation though.
I know the 2nd option is possibly easier and cheaper - bringing in hot ceiling air with a simple vent.
Not sure really yet.
Can 2 small 60 mm pipes from the stove area really bring in enough air to warm up the bedroom a little? ( know the exit flue pipe at the back quickly reaches 200-250c which is a lot of energy to tap into) (I may also find I have trouble getting them down between the flue and flue piping in the tight 30x30cm flue.
oh yes for sure I was planning to add a fan. Looking at small efficient ones possibly a fast pc cpu fan running at 3500 rpm. 7cmx7cm. 12v.60mm is pretty small for a passive duct. A small fan or blower would help move some air through that pipe.

It's so nice to be able to light the fire even with the door partly open with the smoke not coming out, the draft sucks up the smoke efficiently up the flue. Our old open fireplace was so smokey, sometimes not enough draft, and the smoke would overflow into the living room. Had to open a window to create more draft which let the cold air in!!
Yes, very small, even for an active duct. unless it is under a lot of pressure.60mm is pretty small for a passive duct. A small fan or blower would help move some air through that pipe.
That sounds like a better option. A ceiling fan at the high point would also help a lot.Possibly another option. In the living room we have an open staircase just next to it without a door and a very high ceiling to the top floor where a lot of hot air collects and is wasted. This high wall is the bedroom wall.
I hole with a grill and fan to suck in that hot ceiling air into the bedroom may be an easier option. Not as much hot air but utilizing that wasted hot air at the top of the stairs.
As a test, take a table or box fan running on low speed and put it in the bedroom, on the floor, blowing air out the door into the hallway. The cool air being exhausted from the bedroom down low will be replaced with warmer air from the hallway at the top of the doorway. Take the BR temperature before starting and then check it again after 30-60 minutes. In our house I noted a 5ºF increase in the bedroom temperature after 30 minutes.
Unfortunately haven't got a fan strong enough for this test. Just a couple of small usb desk fans. They won't do much.As a test, I'd still try it as suggested. The air displaced from the bedroom will be replaced with warmer air from the hallway.
We have plenty in the beach house but not here, unfortunately, as we have a/c in most rooms. Doesn't warrant me buying a new one for this test.Do you have a local thrift store or goodwill equivalent? They might have one. Does it get hot enough in the summer to warrant having a table fan?
