Heating system fails after removal of radiator

[Mitch1976]

Hi!

I have removed a radiator from the system. I will eventuallt reconnect it once I have moved the wall it was on.

In the meantime I wanted to turn my heating back on.

I refilled the system with water, bleeded all radiators and turned the heating back on (mains). After a few minutes the system shut down and there is no heat coming from the radiators, nor is there any hot water.

I have shut the system off again, let it stand and when I turned it back on again - nothing!

I have noticed that the pump (located next to water tank in aering cupboard) is very hot.

Any ideas - other than calling a plumber?

Oh, it's a gravity fed system, not a closed pressurised system.

Should I have connected the two pipes where there was a radiator?

Cheers for your help,
Chris

no you dont have to connect the two pipes together unless its a very old and rare one pipe system which i doubt sounds like you have an air lock have you bled the pump are the pipes either side of the pump getting hot

It's a Saunier Duval Xeon 40 FF ... and only the first diagnostic light is one. (the one on the right out of the row of 4).

not bled the pump. How do I do this? The pipes are modeately hot, only from the pump I think!

possibly a one pipe system.

It's a 2 year old house so I doubt it's a one pipe system?!
