Thermocom boiler ????????

[gatesmr2]

Hi

Fitted new thermocom 90/130 oil fired boiler just before xmas and it was working fine
Then as old boiler rotted i decided to add primary care(central heating inhibitor) from ridgeons think it,s there own brand, but since i added this i have a knocking every now and then also have noticed what sounds like air rushing through the rads also but have bled them all 2 or 3 times and all i get now is water

It,s not a combi boiler and i did,nt replace anything apart from thr boiler so the system is fine but wondered if someone could tell me how to get the air out of the system (assuming thats what it is ) as after bleeding the rads i,m at a loss

Hope this is clear enough ohh and one last thing if it makes any difference my system has a header tank in the loft which i drained (pipe out of system while holding up ball in tank) then added the primary care then let it refill.

Thanks for any help you might be able to give

there should be a couple of tyre type valves next to your cylinder, try these

After spending so much money on a brand new boiler it always surprises that some people dont bother to add inhibitor and even those who do dont use a quality product by Fernox, Sentinel, and to keep Keith happy, Camco.
