I have a sort of rectangular house with a 25 m2 living room at one corner, and the master bedroom at the opposite long corner of the house. All of the bedrooms are up another level from the living room by 4 steps.
I installed a wood burner in the living room a couple of years ago, and I was assured it could heat the whole house up, but of course it's not doing so. When I have the fireplace going, it could be 28 deg C in the room with the ceiling temperature at 32 dec C. But the heat is not circulating and is being blocked by the wall above the living room doors. The bedrooms would be at 12 deg C.
I had a builder create a transom window above the doors and that helps only a little.
I don't have a ceiling cavity to install heat transfer ducting.
But I do have a play room under the living room, and I could put a grill in the floor of the living room and duct it to the 4 bedrooms though I have no idea how well that would work pulling hot air at floor level rather than ceiling level.
Is this a practical solution? Or, is there something better? Should I be pulling cold air from the bedrooms and push it to the living room instead?
