Hi all,
We're about to get ourselves a new boiler fitted (Worcester Greenstar 38CDi) and are aware that the system needs to be cleaned before the installation especially as our current boiler makes a lot of banging noises when heating hot water so its likely to be pretty dirty. The rads are generally heating up OK with only one having a cold bottom which we're going to replace before boiler installation anyway.
My question really is, I asked a local heating firm (BlueFlame in Bristol) to do a powerflush (as they advertise on their website). However they came round yesterday and ran the system for maybe 4 hours with powerflush chemicals and bigger magnetic filter than our magnaclean but no pump, just using the boiler to pump it round. I sent them an email last night asking for clarification and there response was "We use a magnetic filter system to flush through which uses the same chemicals. You get exactly the same results and it is kinder on the heating system." So now I don't know if I'm just being ripped off. Is this likely to be good enough for a new boiler warrantee. The only evidence I'll have from them is a receipt saying the system was flushed! They're charging £420 for 10 radiators (but not yet paid)
Any advice would be welcome!
Thanks
Caroline
