I hope someone can help. I have a wood burning fireplace that has heating vents on each side of the hearth. This makes for an extemely warm family room, kitchen and living room but very cold bedrooms and basement. I have tried to run the furnace fan to circulate the air but the position of the cold air return (floor opposite the fireplace and behind a loveseat) doesn't pull the warm air. Is there something I can do to get the warm air to the rest of the house? I burn fires 4-5 days per week. Thanks.
