Forgetting those with just a few reviews it appears that virtually all
the boilers mentioned are more than a little unreliable.

Take into consideration that if your boiler is working ok, your
probably
not going to write a review. The ones likely to write are the folk who
have had problems and want the world to know about it.

Worth noting that their "top five" are a Vaillant and two Worcesters,
exactly what the experts in this group say. (The other two look like
adverts).
It would be interesting if geoff can tell us if he gets more Worcester
parts or Vaillant parts in for repairs? General consensus seems to be
the electronics of a Vaillant are more solid...

Yes, I get a lot of worcester stuff coming through now

I used to recommend them to people, but I have given up doing that

However, it has to be said that there are an awful lot of worcester
boilers out there (I have one)

Vaillants do seem to have a slightly better track record

I had someone phone up today who still had the original (15 year old)
pcb in his suprima boiler and wanted a fan instead - miracles happen


Geoff, Is there a pattern to the type of faults you see?
Maybe dry joints due to thermal stress or relay contact dirt/failure.
In the field of electronics I worked in, components were very reliable
unless over stressed in some way. Heat and dirt were a source of
problems though.
Conformal coating used to help a lot but I doubt that they use that.
Maybe the boiler designs are cut to the bone?

cheers
