I live UPSTAIRS in a converted barn - c 150m2. Have GREAT woodburner in living room and want to redistribute heat to bedroom and office. BUT, should I also allow for an inlet into the living room (this will be my main source of recoverable heat as the fire is just mega - and the room is well ventilated). Other return vents in kitchen and shower.

Also - any recs for heat recovery units that work well - are quiet - efficieint - and great value for money.
