Heat Requirement:Originally posted by red
Facts: 2,600 sq ft house in NE Oklahoma (2,300 down, 300 upstairs game room), two separate heating and cooling units, the upstairs is connected to downstairs via a closed-sided stairway with a doorway at the bottom of the stairs (no door or open railing).
The question is: If the upstairs heater was run sparingly (keeping the upstairs cooler)
Two people and
small upstairs furnace weighing about 5.1 # times Two, because you only wish to provide minimal heat upstairs.
250 CFM Cooling ought to just about cover it.
