No boiling, no expansion, and all the air is burped out of the main system.
I think it would be good to hear if anybody is going anything to reduce external corrosion, other than painting the whole thing including the fins.

Man, I've been reading on this anode subject and now my head's about to explode! LOTS of opinions!! If you want read some good debate check out this forum thread:
