Do a whole house heat loss. See what the requirements are for that
room before and after the changes. Check the other rooms as well.
Particularly the room the t-stat that controls that zone is in. If
that has too much baseboard the t-stat will shut down before other
rooms have received enough heat.
If the heat loss indicates there was enough baseboard there may be
something mechanically wrong with the system, bad zone valve, circ on
its way out, excessive loop length, excessive heat emitters on the
loop.
