Is a combi boiler safe with NO mains cold water? (Urgent)

[chris watkins]

I love it when Chris joins in as he seems to find these little one liners from nowhere that supply a definitive answer in hard format.

Right, so now that ones put to bed, what else can we argue about....?

Well thank you kind sir.

Sorry everone, could'nt let this one drop, so I have done the homework and spoken to ferrolli technical. They say that if you run the boiler with the could water main turned off then there is a significant risk that the heat exchanger could be damaged. Especially if any hot water draw offs were left turned on.

So technical man contradicts the manufactures written instructions, well I know which one I would believe !!
Now please, can we put this one to bed now.

Having read 73 posts and all disagreeing with each other, the "op" must be totally confused.

BTW I get the gist of what an "op" is (the person who asked the question, I assume) but does "op" actually stand for something?

I had already mentioned that ferrolli engineer had warned me of this, but other people know better.

I always assumed it was original poster or original post?

Oh thanks lame for mentioning this again, do you know I missed it the first time you did post it, how silly of me cos had I have seen that a Ferroli engineer had told you that, I would changed my view completely & not bothered to go on & post what I did.

Sorry, I will read your posts very carefully from now on.

So, your tech guy says if cold main turned off then don't run boiler in ch mode ? isnt that like not turning on a hot tap ?

I have spoken to many technical lines in the past I have also worked for a company who had a call centre in there and none of the people were technically trained so were just reading things off a computer screen so if its not written in front of them I wouldnt believe a word they say. As for the ferroli engineer they would say anything to hide the fact the boilers are rubbish and they leak like mad.
