i had a stand up cast iron radiator in hallway of my house. i decided to remove radiator and use supply and return connections for some cast iron baseboard. i lengthen the connection an additional 15' from where they were and reduced them from 3/4" to 1/2". the length of the base board is 12'. the system i have is a converted gravity hot water, circulator add to system.i bled all radiators in house and baseboard, but my length of baseboard is not heating.what did i do wrong ?

    Pressure drop

    Your changes added restriction , enough restriction to over come the systems pressure drop.Pressure drops between the radiator risers creates flow of the system water... Before the flow traveled less distance with larger piping You also may have a air trap in the new pipe , any loop up pipe work is a air trap. Either a bleeder or a way to force the air out of the trap would be the correction. ... Added note on pressure drops..A reverse return would be the way to go to help balance the system, which should have been done when the circulator was added..
    I have enough experience to know , that I dont know it all
