Hi all,
First post here so go easy on me.
I've got British Gas homecare and just had them out for a boiler problem as it kept overheating, he diagnosed a blockage in the gravity flow pipes so all the heat was kept down at the boiler end. To cut a long story short he advised a powerflush (for £600-700) or a new boiler as this is quite old and getting obsolete, but he said it's worth adding some Fernox F5 as this could quite easily clear the blockage, so he added half a litre to a radiator and advised leaving the heating on to flow it around. Fingers crossed this will work and the heat will flow upwards to the cylinder again.
What has concerned me is getting back to work I googled F5 and everywhere I read says it should be cleared out once it's done its job, but he told me its perfectly safe to just leave it in.
Just wondering what the advice here is?
