WE just moved into a house with I believe hot water radiator heat. I bled the heating starting from the farthest to the closest radiator. This is where my confusion begins. I bled the radiators on the second floor and only steam/air came out. Then I bled the radiators on the first floor and a little air came out then water. Was water suppose to come out of the radiators on the second floor also? Please help me!!!!!
