On Friday night my Vaillant Ecomax 828/2E boiler (fitted June 2003) sprang a
leak and drenched the whole bathroom and kitchen underneath. The cost of
repairs is going to be considerable.
The boiler engineer came out Saturday and established the leak as a fault or
error as part of the manufacturing/assembling process. Inside these modern
boilers a lot of pipework is held together by spring clips which sit in
grooves and hold the copper piping - complete with rubber O-ring - in place
Well that is the theory. My main water feed to the boiler which will be
the first bit of pipework with these spring-clip connections came apart and
leaked. There is mains pressure in this pipework but fortunately for me the
pipe did not completely detach.
The cause of the problem, according to my installer, was that the spring
clip was NOT firmly and correctly seated in place and he went on to say the
the top bit of the clip (shaped like a horizontal "U") was in its groove but
the bottom part of the clip was not. Over time and with boiler use -
temperature changes, pressure fluctuations, humidity, vibration, etc, the
clip has failed to retain fully the copper pipe inside its fitting among the
boiler components and started leaking (pouring in my case).
This is part of the boiler that installers should not touch or interfere
with during the installation process as they are "ready to go". It is also
highly unlikely that these clips could come loose during any transportation
once they have left the factory. Which leaves an error on the production
line - i.e the clip was not fitted properly by someone in the factory. This
makes Vailllant liable I guess.
The reason these clips are fitted I am told is to make things quicker to
change over should components in your boiler fail. There are no compression
joints or soldered joints to mess about with, just pull a couple of clips
and replace the bad component. I personally don't like this. Had I known
that my water mains pressure was being held in by a clip on a pipe I would
not have gone down the Ecomax route.
There could also be design faults with these boilers and how the pipe
retention clips are used/made but I haven't heard about design problems from
Vaillant yet. Anyway my water poured all over my circuit board although the
installer dried it out with a hairdryer and got it working again. The
Vaillant engineer is coming on Tuesday and I will speak to him then about
potential design defects (and compensation).
If my installer is adamant he did not partly dislodge this clip and Vaillant
say there clip was firmly seated in place on the production line then a
design fault becomes more alarming and probable.
I urge you all to check your component parts inside the boiler and check all
these spring clips (there are several) to make sure they are firmly seated
top and bottom in their grooves. And if anyone else has had problems of
this nature pleas let me know.
