How many heating vents do you have down there?
I'm assuming it is a full basement, thus you have 900 or so sq ft to heat. I have a similar situation, but one half of my basement is finished with full wall insulation (pink stuff) and has a couple of layers of removeable carpet on the concrete floor.
The half that is still concrete walls and floor is impossible to heat to comfort levels compared to the finished half. The same underground temps that make my basement so nice and cool in the summer fight tooth and nail to keep me from warming the basement thoroughly.
80% is finished basement with 2" rigid insulation glued to cement block walls and Roxul insulation in between 2x4 stud wall but no vapor barrier as rigid is tuck taped at all seams and batt insulation in joist cavities. I think my problem is where thermostat is located. I have 5 heat ducts in basement all at floor level and 2 returns.
