Attic apartment in heritage house has just had a kitchen reno by my daughter. Her hubby loves to cook but he’s always smoking up the kitchen or having issues with vapour. The open kitchen window and fan helps a little but not enough. The wall behind the range is very short and the ceiling is sloped. My contractor said the only thing he could suggest is a downdraft stove but there are only two 30” made and one has a terrible reputation. The other is VERY expensive. Also, the stove they have is 24” so a reno on their new kitchen would be necessary. The opposite wall has a radiator. Anyone have any ideas? Thank you so very much for any thoughts!!
