Air or a deeper problem

[mad_angler1]

Hi guys. I posted some weeks ago that my boiler was being moved to a new location ,2007 ecotec plus 837, I also had those pipes changed that have a habit of bursting for the solid copper ones my Plummer has done his business and commissioned it however it had to be re drained down whilst i finished further work on my system in the house, all done and. Iv filled it and added inhibitor.

I filled it with the Filling program and ran the P0 multiple times with the cap open. All rads bleed and the system is working however when on full power I'm getting some noise from it, not Kettering but more of a howling. Plummer popped back and believes its either air trapped or posable crap in heat exchanger that may have got dislodged when the pipes were changed as their was some rust coming out of them when I had a look afterwards, did not have any problems before the move and all was fine.

He has advised to run it for a bit and keep trying to bleed it out and see if it goes,

Does this sound correct or any other advice ?

Thanks

Try an x800 cleanser if u think it may be dirt

I'd think you'd need a 2nd opinion maybe? Someone who know's about flow restriction or noise issues maybe? At a guess

It may be worth having the plumber who commissioned it come back or have someone who knows the commissioning procedure of the boiler to check it over.
