This is so similar to mine. Hot upstairs and cold downstairs (although I do have thermostat and valve on hot cylinder.
I've been losing my radiators gradually. Early last week I had all cold downstairs. After reading advice on this forum I spent Thursday evening working my way round all radiators one by one just concentrating all the flow through each. By the end of the evening every one had had a period getting up to temperature. I left 4 turned on but Friday morning when the timer called for action I had nothing. Everyone was cold. The pump still turned, the boiler and flow pipe were scalding but nothing in the radiators.
I've had a plumber in today and he drained one radiator down and pronounced the water all most clear enough to drink. He's added chemicals and now I have some heat (2 radiators scalding, 2 radiators very warm, 2 radiators luke warm and 1 radiator stone cold) while the Hot Cylinder is turned off.
The pump is mostly making a grinding noise although a bleed of the screw above the pump (off the tee that goes to the cylinder) produced a hiss of air, some gurgling and then a 5 minute quiet period.
Do I need a power flush?
