Beachcomber, I am talking hot water. Ive never seen a large cast iron
radiator without an Air Bleed, or you can`t ever get the air
out....Maybe you are refering to baseboard.
You dont bleed steam manualy, the steam vents do that automaticly by
closing .



I don't know how to say this politely, but you don't know what you are
talking about. Perhaps this website will help educate you.

They are DIFFERENT Systems. The Steam Heat System is the older of the
two. STEAM HEAT VS. HOT WATER (HYDRONIC) CIRCULATING HEAT. THEY
USE DIFFERENT TYPES OF BOILERS. AGAIN CHECK OUT THE WEBSITE ABOVE

Steam Heat = Big cast iron radiators= one entry pipe with a shut off
for the steam. Air bleed with a manual or automatic valve. Operates
at high temperatures.

Hot Water Heat - radiators have an inlet and and outlet pipe. No air
bleeds on the radiator. What you call "baseboard" . Operates at
Medium temperatures (below boiling water).
