Back again. Getting new system installed soon but need heat now. New pump sorted problem for a day all rads roasting hot. Gone back to old situation upstairs warm downstairs cold. So. Drained whole system emptied rads. Then sealed them up and let system flush all air out via drain valve. Filled from ground up bleeding air out. All good confident no air in system. Fired boiler up with rads upstairs warm and all cold downstairs. Stumped!
