Hi,
I've got a cold radiator attached to my combi/sealed heating system. I've checked the pin underneath the valve and it moves freely. I also closed both sides of the radiator (valve and square tap) and removed the radiator.
When I have done this before on other radiators, it hasn't affected the pressure of the system as a whole, but this time, it put the pressure down to zero and the boiler did an error-reset. Should it do this, as I thought closing both sides of the radiator should retain the integrity of the system?
I put the radiator back on, bled and refilled until the pressure got back up, but i've still a cold radiator.
I wasn't in the house when the radiators were fit and the floor in that room is tiled over concrete, so i can't easily have a look at the piping. Does this sound like an obvious fault? Any ideas?
