[fishy]

hi:
i reacently moved rad on baxi solo heating system, since then can't get heat into rads.have drained whole system andremoved rads and flushedpump seems to be working , water red hot before and after pump
but seems to travel slow up towards rads could this be pump trouble or
mid position valve failure

[bobplum]

sounds more like an air lock or the rads need to be balanced
