In general the basement is always about 5 degrees cooler than the rest of the house. It isn't unusable but it sure makes the bonus room upstairs more appealing.
Our house is about 8 years old and the basement was developed by the builder. I had my furnace checked over when I was having AC issues and he mentioned the furnace is "just" big enough and that the basement ducting isn't the best. He attributed this to the cool temperatures.
We will not live in this house forever so installing a direct vent gas fireplace is likely not worth it.
Is there and economical solution out there? I was looking at wall mounted electrical heaters but was thinking the operating costs would be high.
Suggestions?
