When the bed is "made", we don't need the outlet under the bed and see no need for the couch outlet. What I would like to do is redirect all the heat to the outlet at the head by closing off the previous 2 outlets. Should I be concerned about not enough airflow away from the furnace if I block or discontinue the outlets? Since the outlets connect to each other with a wye, I could just cap off the outlet and have the heat flow to the second capped off outlet and then out the last one. I don't think this will hurt anything regarding airflow but wanted to check anyway before I start. What are your thoughts.
It probably won't be an issue, but you should check it. All furnaces have a maximum heat rise specification, which is basically how much it heats the air in degrees. It is the indirect measure of airflow. It may be in your manual, but I had to call the manufacturer to get ours. Just check the heat rise the way it is, and then tape off the ones you don't want and check again. Hopefully both will be within the spec.
