	I am trying to heat a 30 x 30 room in an insulated barn. I'm using an electric garage furnace and don't know the air flow possibilities. I would like to know which would be better, a 4" or 6" insulated corrigated heating tube on a 25 foot run? I have an 8 x 20 heat opening coming from the furnace duct. Would it be better to do a trunk line for the 25 ft and then have 4 or 6" tubes coming off of that or devise four separate trunk lines of the 4 or 6" tubes, two going 15 ft and two going 25 ft into the room? Basic question, will heated air cool faster in a 4" tube at 25 feet or in a 6" at 25 ft?

	You probably don't need any duct work, and certainly not insulated....If the room is open just shoot the air across the room.... Will the A/H be vertical or horizontal...? Heating only?

	Its call thermal conductivity. The heating rate would be the same __________________ “ When people get what they want, they are often surprised when they get what they deserve " - James Wood

	It would be better to locate the heater in the center of a trunk line, then, the air only has to travel half the distance to the vents,and can be a smaller size,because it only carries half as much air per leg.I would run a 14x14(15 feet) to the center of the room, where it would connect to a 10x14 "TEE" trunk running 15 feet in each direction. Then put your registers where you please. IMHO __________________ "A man never stands so tall as when he stoops to help a child."

	Thanks, you make sense. By taking the majority of heat go half way thru the room and then have small lines take off from there sounds logical. I appreciate the input.

	Why not just install one of these in the barn and have it blow diagional across the space? http://www.growersupply.com/mod17btuheat.html __________________ To be or not to be........ok that's a trick question.
