Air in Central heating system

camerart · 13 May 2012

I have flushed out the central heating system with Sentinel X200, drained it, then repeated this. Filled it with Sentinel X100. So far I've been able to bleed the air out of the system, but this time I can't. The heating works ok, but with the heating pump off the thermal flow doesn't work so no hot water.

Any ideas?

Cheers, Camerart.
