i will stick to what i said, they are open vented & no different to any other open vented boiler, ventalation should be taken from the outside not just from another room, the foam seal on the ridge tile falls to pieces, the bolts that hold the flue to the ridge tile rust if they are metal & fall to bits, if they are plastic they snap, the air that comes out the vents is drawn from the room the unit is in so yes the ducts & grills get full of dust over time, people block up the vents so you don't have cold air streaming in,

totally outdated i'd get rid cy

Do you live in a house with warm air..........or just talk Hot air.
How qualified are you?

As for out dated..... still installing them.......... so how wrong can you be!

My first house had a J&S warm air heating system and it's the best heating installation I've ever known – way better than the retro fitted gas radiator systems in the houses I've owned since.

You shouldn't underestimate the value of a system that was professionally designed for the house it heats – the heat loss calculations are accurate and the siting of the boiler and routing of the ducts is not compromised.

Most J&S owners will agree that the filtering of the air being circulated reduces airborne dust. As others have said, getting advice from neighbours and finding a gassafe engineer who is familiar with the product should solve all problems.

!!!!!! cy turn it off until you can get it looked at by an RGI, you need someone with warm air on their GS reg NOT just boilers, it takes it's air from the room it's in & normally the fumes go out through the loft & outside via a ridge tile, if not serviced & maintained these things are b1oody dangerious

check the ventalation going into the room hasn't been blocked off

It has been chap, (I'm not quite that daft yet), checked for correct combustion and leakage but again, he wasn't familiar with this system and went away saying he get onto the manf and get back. That was 4 weeks ago hence my attempts to unearth a little more info. And yes still trying to find someone who has worked on these.
As Furts suggests and I'm sure he's right, it is a dust issue, you can actually taste it in the air. My concern was that if the ducting isn't blown and vacumned under service there will be little improvement. Having removed several exit grills they are full of very fine dust.

They have 3 months max and then they move out for 4 months while the work is at it's heaviest

As regards there being a number of properties with the same system, no, the original propety was a manor house set up a private road, 2 massive bungalows were built in the grounds before all 3 being sold in the 90's.
The other bungalow changed theirs over 10 years ago.

Well I have the above system. Its a marmite set up . love it loathe it.
We love it .



Can be a very dry atmosphere ( makes a change when half the threads on this board is about damp/mould)


Just the one already mentioned.



They are VERY helpful



No and No.



Never had any foam seals.




That post was so wrong , don't even know where to start.




Should have one high and one low LARGE grills very close to the boiler , both from the same room




Why ? Dry yes ......... but is the house already very dusty?
We suffer NO dust.
Well thats untrue .........do you remember Buncefield explosion a few years ago? The site is only a few miles away and the blast of air that Sunday Morning , blew the side of the bath off, lifted the loft hatch and whistled thru the Ducting ...that did cause a 'little' dust'


My qualification for this post ..........I live with the system . My guess its ALL down to such a dry atmosphere.

Well I thought the same, hence water and sponges against every outlet, but it's not as my post above explains.

Yes the vents are in the same room and yes they appear clear, but to further clarify and I didn't know this until late yesterday, my DH bought a new vac at the weekend and got 3 full dyson loads of fine dust from the carpet in the central hall alone.
(This is 22ft square to give some idea of the scale of this place)

It has to go anyway, this is the issue, the finished bubalow will become a large 6 bed house, existing wouldn't cope and to be honest I doubt it can ever be cleaned effectively.
I won't argue re pro's and cons, no doubt a well maintained system is fine and it certainly is quick, but I liken this to a wet system that used "iron" pipework with no corrosion inhibitor, it's clogged and never going to be clean again.;);)

Shows I know as much about computor abreviations as I do about domestice blown air heating then, DH + daughter in my rapidly diminishing mind:D


Can 1 of you guys with this unit put a pic up so I can see the filter arrangement of the version you have please?

wallbash

Look at the 'huge' boiler.
Half way up there is a lip, just pull, the filter separated ( horizontally ) the bottom half from the top, So its the full width of the boiler and the full depth .

I don't ever wash, just take it outside and tap it on the stone patio.

3 full dyson loads of fine dust from the carpet in the central hall alone.

And I assure you thats NOT caused by the boiler. Logic must tell you that.
The boiler heats air and not water , 'normal' gas boiler does not cause dust, nor does a warm air.

Its the horizontal line on the diagram , just pull it out , slide back

Yes seen the drawings, there is no slide in/out arrangement that i can see, if there is then it's taped over with duct tape.

Now we need to get this straight, I'm not blaming the boiler, I'm saying that the whole system is contaminated by dust, same but different just don't view it as me having a downer on blown air, I don't.
Read my comments on the carpet, it now all seems to be being recirculated so here's what I'm going to do;

I will figure how to operate the unit on low temp but full volume.
I'll shut all outlets.

I'll make a plywood collector that fits over the duct and has a vac point.

One by one I'll open the ducts with the vac running and system blowing to give max airflow and airspeed. If anyone sees an issue with that logic feel free.

I can't see the unit from here, so will check again re the filter when I go back, but I was looking for the optional clean air unit and cannot find 1, I think the GS guy mentioned this to the "DH"

Huge 'lip ' full width of boiler ............don't like the sound of duct tape , its a self supporting wire mesh filter.

Feeling free.

You want to 'blow' ?
Where do you think any dust in the system will go? My ducts are many metres long, I would think 'suck, just force hoze down the hole.

So putting the pros/ cons aside. Its a dust problem ( and not caused by the boiler)I hope we agree on that.

So what caused all that dust ?
Filter is 57 inches off the floor
