We have bought a TB320 braemar heater. The installers want to put both the ducts and air return grille in the ceiling (11ft ceilings). I know that it is ideal to have the air return at floor level, but they want to put it in the ceiling in the hallway (which otherwise has no outlet duct). Anyone have any advice on whether this will be terribly inefficient, or if it is a feasible setup?
Thanks
