My name's Allen Hart and today I'm doing day in the life of a gas engineer so
being called out to to a Baxi Gas Boiler so it's been it's been capped off as has
been unsafe this boat is about two years old apparently it was installed by
gas safe registered engineer I'm gonna have a look at all pipe work I'm gonna
ring gas safe if just just see what's going on here so what I'll do now is well have
a look and I'll show you I'll show you the faults with this and I'll show you
the reasons why it's been capped off and then from that I'll rectify some of the
issues and then we'll we'll hopefully get it back up and running again so
let's have a look now and I'll show you I'll show you around
round the boiler so this is a buck seen gieux attack boiler in my opinion this
is one of the best boilers of all time really bulletproof boiler and it just
does what it says on the tin so if we have a look underneath with this first
so we can just see it's been capped off and then if we have a look the pilot
just so the boiler was just plugged in there's no spare from the boiler and
then everything else all looks all looks like it's all okay and then if we go
into this room here
we're going to hear what conceit flu goes through but if we have a look
they've got power of the flu missing so when we actually look inside this is
that some it's actually exponent it's actually that insulation board put just
to pop it up just to just to start like hold it up what set this off now I'm
luck a bit bad so there's no paperwork for this boiler as such so there's
there's no benchmark that's so normally another benchmark booklet and of all the
readings in of the emissions and and all the bits and baths for when it was
installed so there's none of that here these some paperwork there's a gas
safety certificate that's dated March 2018 and there's also something here to
suggest that was fitted on December 2016 I'm gonna ring gas safe up and I'm just
going to just double check about that but yeah so so let's have a look let's
have a look at the boiler I'll take this flow off and yeah that's gonna look it
now I've got this flow up now
so I've obviously got an issue there with how the flue falls as well it's got
water water in the flue so we'll have a look now so I'll just
pull this I'll just pull this that actually looks like looks like it is
long
so I know that's just loose is that I
don't know what type of flue that it's obviously some saw a plume kit a bit more
so when I'm looking at this that looks like that is the normal flu because
that's got the the the Weather ring in there so if he trips why from outside it
runs off and it's got the skills in there and another thing to find out
where their spins move this so just got a new flue if you have a look on a new
flu it's got that ring there and it's got a spear points there the skill goals
so I'm wondering if a builder as checking the end off this end off here
and then just put some some sort of plunk it up inside of that and we'll
it's it's off topic boiler know I'm gonna tell them you knew this flue just
so I know this is all salt correct this part of the flue as you can see from
there it's all cemented in so this parts being done installed well if you can pay
it's that bit
it seems very different my belief is a builder has extended this and not the
original gas engineer I'm still going to check we got safe and we still got no
benchmark but customer could have the the old customer could have taken that
with them because this is something new now that lives in this property
so this looks not too bad any area where the mid an effort is sealing it with
some of cement so I'm just gonna remove this elbow now just one thing I have
noticed there the flue absolutely falls away from the boiler so it falls down to
what would be outside so that's why it's add water in the flue
so the flu should always fall back to the boiler so that's something going out
way so as I can see now that's just a standard telescopic flue and this were
all cemented in really well as I say it stops them getting out so I'm just gonna
put the new flow on now these floats come with some silicon grease and you
just put something on them seals in there just so that when you put it on
the bow you don't put seals out I don't think to point out as well as this is a
low profile elbow on these now and they need to be
screwed as well the other one wasn't screwed so I'm slipping the supplier
than him so we now no need to check that the new flu is gonna fall back to the
boiler so about there I'll just need to wedge that up so I've done the flue part
of this now so I'm going to connect the gas back up and then I'm gonna test the
gas so just just get this oh yeah a virus like enough
and then people attack that up and I'm gonna go put a test on gas so just blood
tests on gases now so I've got my Titan test I know we have some mixed feedback
on that and I thought became a miser where they work in because I'm gonna
print it out as well just to prove this is right so I'll come back to you in a
few minutes so as we know we've got a farm and it tests
so it just tested a lot by now we're doing a minute sterilization and then
we've got two minutes for the test so just got about eight seconds left on
this test yeah and we can see that it's not drops
oh so I'm just going to print out
I'm also going to get at this now this file is a particular boiler and it's
quite far away and so we're done with coda and the gas is 22 mm so I do
suspect they will be under gassed so I'm just going to go fire the boiler room
and so I'll just turn this stick it off set the burner on so to put this into
commissioning mode our service mod you just put on so they're just come back
and I'll go into service mode so that service mud on high and then you can set
it down to just one thing well you're doing this if you run the
hot tub then you'll stay in service mode longer got an app on before and I'm just
gonna put the reading in so it's 101 101 warm 3.38
so start now and I'll just come back to you in a few minutes
so I'll just don't gas off when it's at five or four or five so we said five
four five so we can calculate right now and it's given is faithful so I can say
it's definitely under guests I'm gonna test this now with the analyzer test the
pressure one thing to point out here we have a
lot could be pressure gauge that was at one bar now this is a big heating system
and it's only got the expansion vessel that's in the boiler
so clearly the expansion vessel is under sized for this system so that's also
something something that we'll have to set a customer to advise to
so the emissions are flying on high law unscrew swap but now reject the inlet to
make sure that that's okay as well
so the admin my spy so pressure gears has gone our way round to free now as
the system has got well so definitely it definitely needs an expansion vessel an
additional expansion vessel fitted I've just called box a and box a have
confirmed that the boiler has not been registered a bank phone gas safe and gas
safe also confirmed that the boiler hasn't been registered so it seems like
it wasn't installed by gas if engineer I don't know the jury's out I have got
some information here which says certificate of installation and it says
that the boiler has been installed as per manufacturer's instructions and
complies with building regulations installed ain't commissioned and it says
the name and it's signed so that of customer looking at that would would
feel that it's been being done correctly so what's gonna happen next is this this
is gonna be required to gas safe and gas it can do some investigations and see so
yeah so I love a lot I'll show you I'll show you at rest of what I've done a
half shot I'll show your flue and then we'll finish up really so you have to
always make sure that you use a gas safe registered engineer and if you're gonna
buy a property it is very easy just a phone gas surf up and just ask them if
the boiler that's been installed has been registered so don't rely on
certificates the solicitor gives you actually for gas if and then they will
tell you whether or not it has as I said the customers got a few different sort
certificates here that would suggest that it's been installed
they said Binney stock correctly it says it's been installed some manufacturer
instructions and it hasn't there's quite a few quite a few reasons
it hasn't so the gas is under sized the blow off the PRV doesn't go to
outside the flue was incorrect also there's no controls on it so it's just
enough for later hasn't even got time or anything to control it so clearly it
hasn't been a very you know a very good install but well have a look at rest of
it now just a block up flue and yeah so I'm just gonna check the water flow on
this just to see if it was the right size boiler for this process I would
never insult viola
so we've got about 10 litres a minute on hot water
I've got about 10 litres a minute at Cold War so we could about a 25 kilowatt
hour 28 kilowatt boiler and it's got 10 litres a minute I'm cold
this boy Lord really you need to have at least 18 19 litres a minute on your cold
water so so the boiler will work to its full potential this boiler is far far
too big for his property you don't need a five kilowatt boiler for 10 litres a
minute it's just madness the other thing as
well the the gas wouldn't have needed to be so big if if right-size boiler so
that could have fitted a 24 on a 28 kilowatt boiler in this property and it
would have just done just as good in fact it probably being slightly better
so yeah it's just it's just crazy really right okay so let's all rest of stuff
now so that's the flue outside all don't know so I can see the pressure has gone
above free bar now if we have a look here we can just see a bit of water
thanks running down from the inside in the house so I just need to wipe that
flew off so sealed it inside and outside and what you need a bit filler
I've only had time to deal the flu today I'm gonna make some recommendations for
the customer so the gas needs to be updated
it needs the blow-off the PRV chicken that needs to be taken to outside
it needs a remor expansion vessel fee as well also it's got some radio valves
that's they're leaking so they will need they need replacing so yeah I uh puff I
hope I've not missed out out that I wanted to put in a hour but if you've
got any questions please please ask them in comments below and thank you for
taking the time to watch to watch this video thanks very much
