I am in the process of finishing my basement.

The area that I wish to heat is 500 sq ft.

I have a two part question; if I wish to heat with an electric fireplace or electric baseboard heat, do you guys think that an electric fireplace that is supposed to cover a 400 ft sq area would be adequate for a 500 sq ft basement rec area? Not being an HVAC specialist, my gut is that this is not adequate.

The second part of the question is, assuming this is inadequate, would adding two 6" runs overhead to the area to be heated from the plenum of my 2 ton HVAC unit be additional sufficient heating for a carpeted basement rec area about 500 sq ft?

So I'd have the electric fireplace + 2 - 6" diffusers from above for this area.

I appreciate your input and interest.
