news Why do I keep seeing overflow pipes (or boiler condenser pipes, or
whatever they are) on people's houses with the pipe curved round 180
degrees so it faces the wall? Why on earth would you want the water
to
run down the wall instead of fall a few inches from the house?

Worried it will damage the wall?

I would think it better not to have your wall soaking wet.

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)

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.


I don't have such a thing so I don't care. I don't have a combi. I
have
a system boiler, and the overflow of the header tank is on the eaves,
stuck out straight, as is traditional.

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.
