Cheers found it - says

"Yes"
brand is blank
product "x800"
and inhibitor "x300"

Rads were only hot for about 30 mins until they finished and not all valves were turned to on.

Could they have actually done a proper job but I should've specified a more in depth clean?
X800 and X300 sound like Sentinel which seems to be a quality brand. But X300 is not an inhibitor.

X800 is a fast-acting flush chemical for old systems and was probably the correct product. X300, however, is a new system cleanser designed to remove grease, flux, and copper filings and should be removed within 24 hours. Then the system should be drained and filled with an inhibitor (e.g. X100).

Is the guy a surgeon by trade who just does a bit of plumbing in his spare time, or just incapable of reading and following basic instructions? At this point I'd be calling Gas-Safe and saying you have safety concerns about your new system as I'd like to know what else he's got up to!

If dirt gets in the new boiler it can cause alot of problems and your warranty will be effected, a twenty five year old system will be choked will magnatite and it would take alot to remove, it needs doing before even thinking about fitting a new boiler in reality this doesn't happen engineers do the swap in a day or two this is just not enough time to carry out the nessesary work involved to do it properly the cleaning alone is a good days work flushing reapeatly to remove clean chemical s and dirt a magna cleanse has made this job alot easier but it's not a way to cut corners the better you clean the system the more efficient it will be.

Two different jobs Ric one a existing alpha boiler kept locking out on high temperature so a alpha mag pro was installed it was chemically cleaned with the magna cleanse fitted , flushed the system that sorted it .

The Viessmann 222 upgrade the system was Hot flushed , a mains cold flush before removing the old boiler then chemically cleaned with the magna cleanse flushed and inhibitor added. No short cut here bud 😂. Kop
