The radiatorshave been purged they are not retrofits) are pretty hot but
they don't seem excessively hot; don't know if circulator keeps running
but will try and check that. The thing about the circulators though is
that they are the small water lubricated type. Many years ago I had these
same type and they would fail if they weren't used or run periodically
during no heating months. Attic insul is approx. r-25. The upstairs is
very warm. Thanks.

Circulators do fail and they are about $50 to $70 to replace (for the
parts). One thing that I did not see was if the problem was new or if it
has always been that way. If it is new, I'd suspect poor circulation. If
it has always had lack of heating, I'd suspect poor design of the baseboard
setup. There may be not enough finned sections in each room.
