I have a breckwell big E in the basement of my ranch house and while it heats up the basement fine, I am looking to get some more heat to the upstairs. I have the ductwork from my heat pump located within 8' of the stove. If I am trying to use the ductwork to help get the heat upstairs, do I want to get the heat into the supply or the return duct? Also I am thinking that maybe I need some vents in the floor to help with the air transfer and give the cold air somewhere to move to. Will cutting vents into the floor have a negative effect in the summer when I am cooling or can I just close the vents and stop the cool air? If cutting vents in the floor is the answer, how many vents should I cut and should they be in the living room, kitchen/dining room, bedrooms, bathroom, or in the hallway?
