Hi
I've just changed my combi boiler pump (vokera Linea 730) due to it dying.
I've refilled the system and bled all the rads but when testing the heating only the upstairs rads get hot. I've tried turning the upstairs rads off completely and I get a small amount of heat downstairs but that's it.
Anyone have any ideas as to why?
Thanks in advance.
