They are two separate things.
Which are you on about?

I have never seen this.

Condensate should be taken to a drain.
An overflow should be in a conspicuous postion so you see it if it
overflows.

Any pipes configured like this are ones which are likely to spout very hot
water in the event of a problem with the equipment like a boiler; ie, they
aren't simply overflows from a cold water cistern. Therefore the intention
is that any such water (which could emerge at force) is deliberately
directed safely at a wall, rather than sprayed over or dripped on a passer

You've had a perfectly accurate and rational answer given to your

And at 3 bar it would come out so fast it would bounce off you and be in contact with your skin for a fraction of a second, so transfer bugger all heat to you. If you're splashed with boiling water, it might hurt slightly and leave no mark, but try dipping your hand into a pan of it, and your skin will be severely damaged. Heat transfer requires time.

They come from the boiler pressure release valve and are positioned like

No there are emergency pressure relief pipes - they should never operate

My combi was installed upstairs, the over pressure vent pipe was taken
through the wall where it exited the boiler, so it is about 8 inches to the
left of the front door, and about a foot higher than the top of the door,
As the door is on the side of the house people have to walk past the vent to
get to the door, up the drive with a 6 foot fence to their right and the
garage at the end,

i know i wouldnt like to be at the door if the boilers over pressure valve
opened and the vent pipe was pointing out so it sprayed over the drive,
my car is also usually parked on the drive so it would be in the line of
fire from an outwardly pointing pressure vent pipe, i wouldn't particularly
want it being doused with near boiling water with inhibiter and other crap
in it either,

i'll wait for creepy uncle peter to come back with something like his car is
built to withstand a spraying of boiler water, and the billion to one chance
of it happening whilst it's parked there.


There was a million to one chance of an immersion heater stat failing
closed, allowing the water to boil and exit the vent/expansion pipe that
loops over the plastic header tank in the loft,
was it a 2 million to one chance that in the bedroom below the header tank
was the baby in it's cot, asleep when the plastic tank ruptured due to the
water in it being brought upto boiling temps by the vent pipe discharging
it's boiling water into it for a few days?

you don't care much for million to one chances when you are that millionth
person,

It'll be placed at the most convenient place, subject to regulation.
Mine's at the same level as the boiler, so about 1.5m above ground.

I think the 180 degree bend, pointing the pipe into the wall, is a
perfectly valid and elegant solution.

Your mileage obviously varies.

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

As against having someone scalded? These overflows are only in use when
there's a fault that will release scalding hot water under quite a high
pressure from them when the pressure relief valve opens, which isn't
exactly an everyday occurence. The wall will get wetter every time it rains.

Bear in mind that as the property owner or occupier, you are liable for
any injury suffered as a result of ho****er escaping form these pipes

We are talking about a one second blast of hot water from the pipe - about a

The nature of a PRV opening is such that there'd be no warning and be of very short duration. Chances are indeed low that it would occur precisely as someone walks past but many 'accidents' are often the result of an unfortunate occurance of multiple instances.

Besides which, why not curve it to the wall? The PRV opening should be neither regular or persistant and so shouldn't cause damage.

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

then you would of course have the discharge pipe.

In which case you could well have a PRV pipe... they are not specific to

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

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.

In which case you could well have a PRV pipe... they are not specific to
combis, but to sealed systems.

I thought combi and sealed were one and the same. A system boiler has a header tank into which it bubbles into.

No. And it is possible to use a combi with a header tank.

No - no relation. Many combis use sealed systems - although there are
some that will run with a vented primary system.

Many system boilers are also designed for sealed operation. Although
again there are exception.

A system boiler has a
header tank into which it bubbles into.

No, a system boiler is simply a boiler that contains most of the system
components in one box - so the boiler, and the pump, at a minimum, and
in the case of a sealed system one, the expansion vessel, and PRV valve
+ over temperature cutouts as well.

If we are talking about the pressure relieve pipe, then that is because
this is the correct way to install them. They should never normally
carry water, so getting a wall wet etc is of no concern. However if they
do operate, they could eject near boiling water with some force - so
making sure this does not hit someone is important.

To cool it quickly and stop it landing on someone standing next to it.

Why is it important to stop something that almost never happens from hitting someone who is almost never standing right next to it? Small number times small number = very very low probability. You'd be better banning cars that travelled over 20mph.

Oh the poor dears.

Because you can.

It's a simple easy answer to a known (and not uncommon) problem.

It's pathetic is what it is. And it's this stupid attitude which is why we have streets littered with speed limit signs and bumps.

The only thing that is pathetic is the name speed bump. The ****ing things
slow you down instead of helping you speed up.
