"Moving" Heat From Warm Room to Adjoining Room
I'm looking to move heat from a warm room to an adjoining room, both rooms approximately 30m³. In spring the cold room is around 12C and the warm room around 24C (the Aga cooker which heats the warm room is turned off in summer).
The Aga in the warm room burns oil (using wicks) and needs a supply of air, so I intend to use a fan (near floor level), controlled by a thermostat, to move cold air from the cold room to the warm room, with a hole in the wall between the two rooms near ceiling level to allow the fan to draw warm air into the cold room. Any thoughts appreciated, especially on how many CFM / m3/hr might need to be moved to equalise temperatures.
