Apollo Fanfare boiler, open system.
Lots of problems over the years but I've now had the floorboards up this week to trace the problem. The flow pipes get hot quite quick and just keep getting hot. The radiator return pipes seem to take an age to warm up on every one of the radiator feeds? Unfortunately the overheating switches the boiler off so it only fires for a couple of minutes. this overheating also now occurs when I run the system on hot water only.
What is causing this? It's been descaled and anti-sludged, drained and refilled etc. The pump is also brand new. No apparent air in the system.
