I am installing an air tight hi efficiency wood burning circulating heat fireplace with a blower and 2 registers. It also has a fresh air supply vent from outside. Our home is a ranch about 1050 sq. ft with an unfinished basement. Attic has plenty of insulation!
The unit will be installed in Living room with one vent on a wall opposite the hallway and stairs to basement and the other vent out the back wall of unit towards the Kitchen & Dining area.
Our cold air return is located near the ceiling and is a double wide grille (7" x 30.25"). I would like to purchase a larger grille (16"x30.25") and open more vent area towards the ceiling to hopefully get rid of the hot air collecting at the ceiling. Our ceilings are 8' and I can NOT install a ceiling fan since I would get decapitated
since I am 6'6".
If I partially block some of the other cold air returns in the other 3 rooms will I help the HOT airflow thru the system?
My current furnace mounted humidifier Aprilaire does not work efficiently so I intend on purchasing the Desert Spring humidifier and hope that works better. I am also installing at least 1 small muffin fan (.3 amp) 280 cfm at ceiling to direct airflow down the 20' hall to bedrooms.
Any more suggestions would be appreciated.
Per regulations I am NOT allowed to direct heat from directly from fireplace blower ducts into central heating system.
