Watching ATOH this past week (Episode #807, Season 8 of ATOH) I came in late and I caught the tail end of a new high efficiency boiler installation. It was a nice compact unit that hung on an outside wall with flexible duct work for exhaust and fresh air intake. I missed the brand and model. Does anyone happen to know what brand and model that unit was? I'm thinking of upgrading and a unit like that would work great for my setup.
