I have oil hot water heating and I have cast iron baseboard heaters in my living room that will not heat up. All the other radiators in the two story house heat up very well. I tried bleeding them several times and I get a little heat in the first radiator in the room but I get nothing in the second one. The bad part about this is the thermostat is in the living room so the furnace is running more than it should because it thinks it is colder than it really is.

The heating is all on one zone...Any ideas?
