I suppose you could fashion some sort of ducting to go around it and have a small fan at one end to push air over it and into your tent; a computer fan is quiet and efficient and should work. The Coleman's are a passive heater though with no fan. You'd probably be better off using one of the catalytic propane heater that has a fan. Personally I don't like the smell of the Colemans but maybe that's just the two old ones I have. ????
