power flush ? if so should be round about a day for the flush depending on system size i use Fernox F5 but thats down to me each installer to there own

X800 is pretty good gear, are you flushing it Kevin or is the boiler installer?
And welcome to the forum.

800 cleaner works well, but given time of year, will your heating be on to push it round the system. Needs to be circulating at temperature for number of days.
Assume you are on gravity at moment, running water through system from header tank will not give adequate flush. Minimum necessary is to flush at mains pressure. Best talk with installer to ensure boiler goes on clean system.

hi thanks B.G doing the install, they are doing just the normal flush F3 then f1, but because of the old pipework i was advised to give it a good flush out then add x800 and run for a few days before they fit the boiler, i took all the rads outside today and fiushed them out.... lots of black water but nice and clear now. going to add the x800 on tuesday and run heating for a few days (hot) then drain and refill a few times the day before the install. is this all about right ? thanks

I hope you have got quotes from at least 2 other installers, who will warranty the boiler for more than a year free of charge!!

you will save £1000.00 by getting other quotes, and the installer will make more money than the sub contractor BG uses to install your boiler.

Hi it's at my mum-in-laws house (aged 81) so it's free boiler deal plus she has to pay £250 for fitting, it gets installed in 1 day, so just want to try and get the old pipework as clean as poss before install also think i will get a fillter fitted at some point... what ones are best? thanks

My missus is burning oil. How old she got to be for BG to give her free boiler.
