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:-) 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 ?


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

then you would of course have the discharge pipe.
