Bleeding Hot Water Heat System
Posted by Mike Rozini on January 05, 2004 at 12:03:23:
I recently purchased a home built in the mid 1930's. It has a new (5 year old Boiler) and of course a hot water heating system. The house is a two story house with a basement. The first and second stories are on one zone with the basement on a second. In every room there is a unit that has fins like a baseboard system only is behind a 2' by 3' vented cover. Each "heat register" has a shutoff and a bleeder valve. After bleeding the system twice, we have one room that does not always get hot.

Should you start at the top or bottom of your system when bleeding each register??
