hello welcome to this train radiators
video my name is James and today we're
going to have a look at a really really
simple process of how to bleed a
radiator in particular this tower out
here they're usually we blew a radiator
when we've done some work to the system
when we're filling it all back up or you
tighten up a leak or something on the
bottom of the rad valve and you need to
get that all sorted out and refill it up
properly there are other reasons that we
might have the bling error to a radiator
and the main one is that there's not
enough treatment in the heating system
water but we'll cover that in another
one of our videos it's a really simple
procedure but you'll know exactly how to
do it after you watch this video I hope
you enjoy it
so you don't all the work that you
needed to do to your heating system and
now you're ready to bleed the radiators
and in particular this towel Rowlett the
first thing I do is make sure that the
lock shoe and the thermostatic radiator
valve or trv if it's present is open now
as you can see here we only have two log
shields - over the mark we pop the caps
off and open both of them fully
anti-clockwise now before we let any air
out of this radiator you must make sure
that either the feed from the feeding
expansion tank and the loft is open or
that you have enough pressure in your
system if it is a serial or pressurized
system you can make sure that if you go
to the filling loop in the airing
cupboard or wherever that may be
or if you've got a combi boiler or a
system boiler it will be inside the
boiler itself always refer to the
instructions on how to read pressure on
a system especially if you've got a
boiler because you have to look at their
specific way of doing it so now you make
sure you've got an adequate supply of
water to the system we should be able to
easily vent air from this radiator we do
that with a radiator key of a very small
square in them at the end but a lot of
the time they have a small slot as well
so you can use a slotted screwdriver
this one here what I always do is a
small small tip for you is I get a file
and just fire off the taper that's on
the inside here because sometimes you'll
be working on a radiator that's been
painted loads and all the paints got
inside there and having the taper on the
end doesn't quite let your key get on
the end of that square let's have a look
at actually how we let all
the air at this radiator and fill it
back up with water so here we have a
normal blue as you can see this one has
a square in it for our key but it also
has a slot in there as well if you want
to use a screwdriver so what we're going
to do is very very simply just put a
cloth up here slack this off let the air
out and as soon as we get some water out
just to close it really quickly and
hopefully our little cloth will catch on
the water
and there we go I said if we look round
here can't you see a small hole where
the water comes out there we go that
radiator is now bled of air so there you
go you see how easy it is to plead a
radiator of air all you need is a cloth
a key a small adjustable spanner or a
set of grips to make sure that the
radiator valves are open this also goes
for normal column radiators or panel
radiators or any kind of radio so you've
got that we'll take a key like this or
slotted screw I hope you found today's
video helpful and informative and thanks
very much for watching bye
