Removing convectors&replacing cast iron

[MasterPlumbersKeymaster]

The previous owner had the bath re-done. at the time the cast iron rad
s were removed from the two small bedrooms and the bath for copper baseboard. needless to say that half of the house is COLD. the problem is the two br’s were made into one loop.I want cast baseboard inthe three rooms.How can I determine how to feed each room from the orig pipes(under windows)
to the baseboard or should I just change the rads and keep the new loop?

By connecting the three rooms together as one loop with its own circulator or zone valve and thermostat, the existing copper baseboard can heat the rooms successfully.

Replacing the copper tube baseboard with cast-iron is a better solution. Either way the three rooms, or the bathroom and the two bedrooms on separate zones, will increase your comfort.
