If the upstairs rads are V.Hot and the downstairs are not then the pump is at fault. If all are hot then the themostat is at fault not closing the boiler down.

is the water in the tank in the loft actually boiling and how many (if any) motorized valves do you have?. It could be a knackered boiler thermostat and no bypass

cheers oillski the water tank in the loft is not boiling but hot if it is the thurmostat that is knackered then how much are we looking at to get this problem fixed i am sure i don't have any mechenised valves cheers for your help
