I have an ecoTEC 28 pro combi boiler and have just drained the CH system as had to re-route some pipes. I've filled it back up (bleeding from the last radiator back) and added sentinal x400. I'll empty it out after 4 weeks and replace with inhibitor.
However, in the meantime my problem is that the heating doesn't seem to be getting hot! Can anyone suggest why this might be?
