Heat bar does not show the excessive heat "given" to you by an enemy flamer. I got "override shutdown" messages twice while the heat bar showed 70% and didn't seem to be influenced by the enemy flamer at all (did't raise while it should).
EDIT: I got overheat damage, so everything with flamers work properly except that the heat bar fails to show you the additional heat you got.
