sitting room rad isnt big enough so replaced that with larger rad and put old sitting room on landon. rad on landon works fine.
sittin room rad is now stone cold (used to be fairly hot, but colder than others) unless everything else is off. have connected hose to pipes and water flows out freely. all pipework is 15mm and sitting room rad is about 20-22M from boiler. second last rad is about 12-13M from boiler.
what are my choices? the pipes take the scenic route form upstairs down to that rad, and if i replace, i can cut off around 7-8M of pipework. think this would help?
OR (to avoid damaged etc), would adding a heating pump before the final 2 rads help?
