Base board has uneven heat

My baseboard is getting warm at the beginning of the system but not at the end. I thought I should bleed the system. When I opened the valve at the end only water was present no air. I let it run for a few little while. Did not want to drain too much water. Do you have any suggestions? Thanks

Is this baseboard on a separate zone from the rest of the house? Is the circulator pump for the zone working properly?

If the baseboard is on the same zone as other radiators and there are several branch loops all in the same zone, are there individual valves down in the basement for each loop? Try adjusting these.

Add some water to the heating system to make sure that there is some pressure inside.

Use a level to verify that the end of the baseboard with the valve is not lower than the other end. If necessary slowly and gently jack that end with the valve up an inch or two (Do not use force). Turn on the furnace or zone and let it run for at least half an hour. Then try to bleed the valve.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

Thanks for your your help. The pipe out of the boiler is hot. The first baseboard gets somewhat hot but after that nothing. It is only one zone with all basebord on same level. I have a feeling it is he pump but how do I determin that? Could there be air in the middle of the system? Thanks again.
