my name's Allen Hart and today we're doing day in the life of a plumber
stroke gas engineer so today we're doing a power flush on an open vent system
we've been coming out to ideologic the customers wanted to put this onto a
service contract and the energy supplier has said that it needs flushing so
that's what we're here to do today so I'm going to do is I'll do like a
overview of what we're doing I'll check up pump out and I'll show you
how I flush your heating system so let's go have a lot so in this type of system
we have a header tank open the left so what we've got here we've got floor that
comes up from the boiler it goes up through the filter so that's pyrotech
filter on on this and then we've got a pump so it goes around here and then
we've got a heating zone that goes for the heating and then we've got another
sambal fire and that goes for the hot water cylinder so what I'm gonna do now
is I'm gonna set this pump out I'm here and then I'm gonna connect the power
flush machine into this so a bit of a change of plan they note some of the
pumps quite quite hard to get off so what I'm going to do is I'm going to
take the filter out and then I'm gonna collect me adapter in there so I'm gonna
remove the filter anyways I'm gonna put on return because it's always better on
return so let's tear this out so I need to remove this olive off here so I'm
going to use this and one of them always pull
just makes it a bit easier you can say that it's definitely not looking at so
I've connected machine in there them connectors and then if we have a look
i've also connected the magna cleansing and what I've done with magnet loans is
I've took one that connectors off among the cleanse and then I swapped it put it
onto the horse for the polish machine and they will end of that this this is
off the blue hose so I'm just made it so that we can adapt it so we can use the
among the cleanse with this powerful machine so this has got a combined and
cold feet and the expansion so what I'm going to do is I'm gonna cut this and
I'm gonna post up endemic and then we can flush the system so this is the pipe
that goes up to the header tank so she'd combined cold feed and expansion now the
header tank still has the header tank is still full of water and there's no water
coming out of here so this this is actually blocked so that's some what we
need so as well so as man that's a nice and clean duster way
so we just push it back
so I've collected the coal feed there and I've put an osprey upon it and then
what I'm doing now is I'm running tank and we're just trying to clear that pipe
Oh so just been trying to wash this tank out still got a bit more to clean out of
there yet so I'm gonna put some power flush chemicals in now so you can use
various different manufacturers chemicals and then we're gonna heat the
system let it run around for about half an hour to an hour with all the radios
fully open and then once we've done that I'm going to turn all the radios off
apart from one and then I'm gonna let the Machine flush through that with the
chemicals until that's clean and then what we'll do then is reverse the flow
on that and just just make sure that that really it's nice and clean
and then what we'll do we'll go to the next radiator to open the next radiator
and then we'll turn the last radiator off and then we'll do that all the way
around the system until all the radiators all nice and warm and I'll
work in and then what we'll do is we'll we'll stop dumping it and we'll put cold
water in and then we'll dump it as well at the same time so I'm gonna go do that
now so we can also do this with the boiler running on this one so we'll get
heat insert system so it's been running now just for a few minutes you can see
there it's already got quite alarming
and that one as well it's all cleaned out now
so then we can check them with thermal-imaging camera so you can
clearly see on that we've got a lot of Thor I'm right inside there and then
we've got flour like done to that as well so we just need to get this a bit
better this thermal imaging cameras not great to be honest but it gives us an
idea so according to this we've got about 74 now I'm not really ER and then
you can see it start like stops and then you can see then we've got 53
in 67 so we can see the bottom of that really I still got sludge in it so I've
turned the boiler off now but we still have a flushing machine going around so
if we have locked the temperature there now it's about sixty seven at one side
it's about 69 at the other and then in the middle we've got it's about 65 66 65
so it's certainly made a big difference now so we can see there that we've just
got a little bit more just to clear out so it's warm on one side it's why I'm
across all other side and then we just got that so we're gonna turn the machine
back on faff to try and clear that so what we'll do we'll go back and forth
with the floor on the machine and we'll get that plate out and then we'll move
on to the next video and then we'll do the same again
so this one definitely needed flushing not that's a bye
so I've taught the filter up now connected the pump back in and we like
to look dead the pipe work because that will blocked work so repacked I've read
back the cold feed an expansion and now we're just gonna put some f1 any bitter
inter system just to try and protect it for future right then guys that's it all
done um so what do we do we did we did a power flush on an open vent heating
system and as you see in the magnetic filters there was a lot of magnetite on
them the system was really badly slashed up so yeah so we spent some time flush
your not system out I hope this video was of some use to somebody and if
you've got any questions please feel free to ask in comments below thanks for
