Hi i fitted a new combination boiler a couple of weeks ago.
Customer complaining the hot water running hot then cold for a few seconds then hot again.
Any ideas to this thank.[/i]

Did you perhaps not flush the system out?



Plate heat exchanger blocked.

Wasn't a ferroli by any chance?

It is a ferroli and it was flushed out.

Just call it a wild stab in the dark... which is what you'll be getting from your poor customer in bout 6 months


Priceless

Well the customer never had much money.
I was thinking of lending her a few quid and putting a worcester in Danny boy.

Would have been nice... if its new nd installed properly get Ferroli out, but be prepared for a fight - they are sccerrrewed.

The fault could almost be anything.

Well the Ferroli will end up costing her more in the long run, it's one of the biggest heaps of carp out there and as they are about to declare themselves bankrupt and disappear from the market there won't be any warranty either.
