By soaking wet do you mean when it rains, you know the stuff well as
you
live in Scotland:-)

We do have eaves you know....


So do I but there is no protecton against rain hitting the gable end of
the
house (or the rest of the walls when it is raining and windy)

You have no eaves on the gable end?

or having the equivalent of a boiling kettle full of
water blasting out out of the pipe in about 1 seconds time should there
be a
problem with your boiler ?

You must have **** boilers if they do that. What was wrong with the
traditional header tank?

They only do that if there is a fault. There are lots of reasons why a
traditional header tank is not used on some installations.

If the fault is common, the boilers are ****. If the fault is uncommon,
why worry about it?



This is not purely a combi related feature. It's a feature of all
pressurised installs. If your system boiler was installed as in the
second
picture in the link
http://www.worcester-bosch.co.uk/hom...-system-boiler
then you would of course have the discharge pipe.

My mistake, I meant to write "condensor", not "combi".

It is indeed your mistake. Condensing boilers have nothing to do with
your
argument and are not relevant.

Condensors are the ones with the outside pipe to let out water.


Of course they are. I forgot about that snippet of information:-)

Actually combi was correct in the first place. Non-combis have header tanks, the overflow goes in there.
