Hello all I'm hoping some heating experts will chime in on this one.I have a 1250 gal switzer gasifier in my basement and have heated my big open log home and all DHW successfully for the first full winter and used about 12 cds .The first floor is heated with radiant tube stapled up with plates I am now finishing the second floor bedrooms and master bedroom.My question is should I do radiant on top of the subfloor with sleepers or use the European style flat plate low temp radiators. the rooms are large ,one is about 350 sq ft and the other 500 sq feet and both are 15 feet to the peak of the roof. I have spray foam insulation in the roof.The rooms even with no heat now never got any colder than about 55 last winter. Each room also has a separate air handler for a/c and I am also considering putting a hot water coil in these and heating that way as they have electric backups in them already. I just wonder what is the best way to go with the wood boiler. I installed most everything myself and the radiant is nice but a lot of work.I would appreciate any opinions
