my name's Alan Hart and today we will
show you how to bleed a radiator please
do not bleed a radiator until you've
watched this video in full the amount of
people that bring me up to watch the
YouTube video I'm bleeding a radiator
and then the boilers not working
the boy is banging and clanging etc so
what I'm going to do is I'm going to
show you the full process so that you
don't have any of them issues let's have
a look now first thing we need to do is
look at the boiler and when we look up
the Bilaam here the pressure is down and
what I'm going to do is I'm just going
to top the pressure up on this boiler
and I'll chop it up to one bar now check
the pressure and the pressure is up to
one bar on the boiler I'm now going to
make sure the boiler is turned off and
it's not calling for heat and now we'll
go to the radiator and will bleed the
radiator why would you want to bleed you
really have to so the main reason is if
your radiator is cold at the top and
it's warm at the bottom of the radiator
then you love or you could have air in
the top of the radiator and what you
need to do you need to get that air out
of the radiator and once you do get that
air out of the radiator the system will
have lost pressure so then you need to
put more pressure in the system so first
of all what I'll do is I'll show you how
to bleed the radiator and then I'll show
you how to check over parts of the
radiator just to see if there's any
other issues with that mediator as well
so the first thing you need you need a
blade okay
and if you're one of my customers in
lades
you will have one of these CC hex
weights please and Iraq well you might
even need or you might even use a joke
whatever where the sucia I could use a
bit
as well so all we need to do we need to
find the bleed point on the radiator
I'll zoom in now and I'll show you that
this is the bleep point here and
sometimes they have a screwdriver slot
in there as well and you could use a
screwdriver to do it I would always
advise if possible to use a bleed key
because the bleep key if you have a look
on there it goes all the way around it
and it won't get damaged whereas if you
use a screwdriver slot sometimes you can
snap them ends off on that wanted to do
we wanted to open this valve here now
sometimes you've got the careful because
when you try and open this this knot at
the top will start to move so it may be
that you need to have a spammer just
available and just get that to
right-size if need be on there you might
just need to nip up a little bit if
that's that's the light from there and
all you're gonna do then is just open up
in your bleep pipe and what you'll do
you'll see water coming out so just a
little water coming out then you can
just close it back up so once once
you've done that you bled that this is
when the problems could stare and this
is when you could have your boiler
banging and clanging or you boiling just
not working so what we'll do now is
we'll go and have a look at the boiler
and I'll show you what you need to next
one thing to point out as well this with
this radiator we can get to this buddy
easy here sometimes it will be on the
back of the radiator or it might be on
the top like on a a towel rail and
sometimes they have a little caps over
it as well so sometimes they they hide
them a little bit but let's go I will
cook the boiler now and I'll show you
the boiler and then we'll come back to
this radiator and I'll show you some
other issues that you could have with
this
as well this is a very good example now
when played the radiators and we tried
to fix the radiator to make it work but
now the boiler would no longer work
because the pressure has gone down I'll
just turn the lights on on this has gone
down on here so now the boiler would no
longer work so what we need to do we
need to top the pressure up on this on
this pile it's quite easy we've just got
a little that a lot of valve underneath
there and we just top the pressure up
but it may be different honorable
boilers it may be that you've got an
open vent system and if you've got up a
vent system it should just full fill up
by itself but sometimes they can stick
so they had to tank up in the loft it
can it can stick in the in the up
position so it may be that you need to
are somebody needs to go up in the loft
and just have a look at that and see if
that's seized in the off put in the in
the up position which is meaning that
it's not allowing water to go into the
central heating system
once you've bled the radiator if their
idiot is still not working then you may
need to just to check these vowels so on
this side we've got lock shield and this
side that's a TIV that's a thermostatic
radiator valve so what we'll do is zoom
in now and I'll show you how to check
them on the thermostat side make sure
it's fully opened on this one it goes to
number five and sometimes the pins on
these stick down you can tip off from
there
the awkward way and then if you have
looked it up in there
what I've seen people do I've seen
people pull wittiness before and pull
them up and I've seen plumbers advising
that and my advice would be just to tap
them down it pushes down on twice I look
where it's stuck down and it'll still
bounce back by itself if you stop
pulling that out of there then it could
just try and pull this out it's not
pulling out to there but I've seen them
pull pull them out before and then what
was that squid top of that Valois so you
just need to be careful all you're
trying to do is just free free that pin
up a bit now what we'll do well then
you'd put your valve well leave your
valve off for now and then check the
other side of the radiator as well
sometimes these can go falter in here as
well so if you just let that off for now
then you'd be able to rule that out and
see if that's a problem or not
well we'll have a look at the locks for
you on that side now so this is the lock
shield it may be that you've got not
shields on both sides you just took the
top off on the lock sealed and then you
just check that this is open on this
just check it's open and to make to open
this you turn it that way so
anti-clockwise opens it the cinemas tap
when you're open in you tap on your
kitchen sink so that's how you can bleed
your radiator and also how you can
just to make sure they don't have any of
the issues and with the Beiler's fill em
up etc I have those little videos on how
to talk you by the rock so hopefully
hopefully you're better to use that as
well
yeah one thing to point out when you're
doing the LOX yield side you may upset
the balance of the heating system so it
may be that you just need to have a look
at a video on how to balance a central
heating system yeah I think that's it
that's it really
