Room 2 Room

Room 2 room, air transfer system is used to distribute warm air from one to other rooms.
(as per diagram)
Installing an inline fan at the source will move warm air to each of the rooms via a flexible insulated duct .
The flow path shown in the adjacent diagram has warm air entering the room, and a proportional volume returning to the source.

This pattern of movement is to encourage flow through open doors or undercut door vents.
Moreover, and equally important, is that the delivery of warm air is adjusted by the resistance created in the return air cycle.
