Hi all im an industrial maintenance spark, have a problem with my central heating at home I have heat on all small radiators up and down, the large two in the kitchen and living room double skin double convectors I have no heat what so ever i have bled both no air in system, heat on incoming pipe work, I have been told it could be the pump or motorised valves? It's an 8 year old house it's an old system with seperate hot water. I've orderd new grundfos pump it feels to be running but it's red hot can't touch it, any help would be great
