Hi, I am building an airtight (as possible) house and am now installing 2 external air supply stoves. I have the ducts in place to bring air in to these but was wondering what brands are available. Anyone have any experience of same. Can you give model numbers? I've read that nestor martin do them but are there other brands i should consider? I can find plenty of sites online selling stoves but none seem to have sections dedicated to room sealed versions. Any help would be much appreciated.
