radiator problems

[johnhunt]

I recently changed a radiator in my kitchen and after refilling tank and radiators and bleeding everything, only some of the radiators upstairs are getting warm all the rest arent.

The emersion tank is only warm not boiling hot as usual.

Anyone got any suggestions. The pump and the boiler seems to be working fine.

Have you tried bleeding ALL the radiators?

You have air in the pipes if there is none in the rads.

how do I get the air out of the pipes?

shut off the rads that are working and that will force the water/air through to the rads not working

Thanks

Also make sure HW circuit is off an any bypass valve is shut.
