Base boards not getting hot.
I have a two room apartment that I am trying to heat. Each room is on a separate floor, have their own zones and are pretty small with shorter sections of baseboard. The boiler is wall hung. It has two taco circulaters that push the hot water through one check valve each. The check valves work. The return pipes converge twelve feet from the boiler before they enter the boiler. The pressure is normal. The output temp on the boiler is 182 degrees. The return temp is sometimes the same as the output and the boiler shuts off while the zones are still calling for heat.
The baseboards are not getting as hot as they should. As a result the rooms stay cool and the system is constantly running. Someone once told me that if the water is flowing to fast the baseboards will not get hot. Could this be true?
Thanks in advance for any insight,
