Interesting angle ProDave. They certainly can't disable it, as it is. It needs redesigning.. & it was eluded to that this was exatly whatwas happening behind the scenes, or rather a meeting, to redesign it. It could indeed be they have no Vaillant germany at all, but using a mfr Co in germany who make it for them. Good points. Thanks zh

So the pump in this heat exchanger, is not the pump outside in the hydraulic thing that is, afaict, all lumped in as one monoblock unit then? O know you cant say for certain, not having or knowing this particular new proposed system of course... but from the link, could you make an ecucated guess? I think this is what i pressed the chap on the phone about, the critical q, & he-said with certainty the problem pump would indeed be outside in this monoblock unit. But this ^ pump wording in the heat exchanger.. has rang alarm bells. Maybe monoblock systems are very likely inherrantly similar, product to product, maybe like ' split' systems might be having this hydraulic unit in the house. What on earth design principle has this hydraulic unit, in the house anywhere, is simply unfathomable to me. Thx zoot

Oh FFs. This heat exchanger has inside it a "Modulating circuit pump". Jesus h christ. Its under 'Features & Benefits' ( benefit?? ) in the same Heat Exchanger link again.. https://www.vaillant.co.uk/for-installers/products/heat-exchanger-module-42880.html#specification Can anyone shed any light on what the hell this thing is? Do you maybe have one? thanks zoot.

Hi John. Tbh the word split had absolutely no meaning to me. I had to figure today that maybe the word monoblock, the first time Ive ever heard this word ( apart from hifi amps, very groovy indeed ), was linked to the word split. Then I guessed that the hydraulic unit, my nemesis, was inherrantly the split part. If I had known this, known of monoblocks, Id have said " there... that's the solution" in a jiffy if it simply meant the pump, the core of my nemesis, was simply located away from bedrooms. Which leads to the bloody question... why why why didnt any of the engineers pick up on this seemingly obvious solution, or if not a solution ( time will tell ) then the most blindingly obvious 1st port of call to suggest is needed, for me, to try to solve this problem. Beggars belief. Anyway, right so this heat exchanger: now this so I recall I was told, does reside inside/ with an expansion vessel he said, these would go where my hydraulic sh*tferbrains unit was. Are you sure it isnt likely to make any noise if it might be similsr to other's on here?

Thank goodness, you concur. Honestly that is vindication right there after a year battling away. Well that seems all perfectly reasonable, your system, the temp figure seems very low... but hey ho i'd not sniff at that. Trouble is, the same frost protection part of the circuit will be in this replacement monoblock, so Im still looking at a similar infuriating cycle... but.... the pump located outside. Its a question of whether this is hugely better, or fractionally so. Id -think- & hope hope hope.. it's the former. Thanks, zh

Great idea! I actually put this to them in april when both chief engineers here, all day, asking me last thing ( both almost given up ) coyly for my video clip of it ( the controller display + noise just captured enough at 4.am ) then cooing how useful it was for them to give to germany as ' evidence '. Zoot! The engineer maestro! I did harp on about being a camera ' engineer ' in my past ie a film camera assistant hoping my theories had credence, not just a muppet blindly guessing at ideas.. like I am at building stuff!

One thing I could ask on here then, if my main question about the differences of the split & monoblock units has partly been answered/ & perhaps a bit too much to ask on here for help explaining... is this, which is at the root of my problem, & for the life of me I cannot understand: The frost protection mode itself. Of course I can understand the principle of hardware, in a frosty environment, needing protection. But I was told today ( i finally got clarity on what this wretched thing is actually doing, in this incessant mode, at 3 am ) that the hydraulic unit ( my problem indoor box ) doesn't pump refridgerant along anything, not inside of course, but also not outside via the HP pipes to the big fanny unit, which is the - only only only hardware- situated in an environment subject to frost, & so my assumption that this is what was being protected. No. The damn pump, pushes - water - around the - radiators in the damn house - at 3 am. When the outside temp guage hits 3*C. When, the inside of the coldest room, in this coldest of houses, has never been below 9*C. In fact I can only recall seeing the lowest figure of 11*C inside the thermostat room. So, I asked tearing my flippin hair out to the very helpful chap ( vaillant phone comms.. great) poor guy, why why why is there any need for any water at all, at 9*C, to be in need of having any frost protection?!?!! It was a rhetorical question I said, sensing he couldn't answer it. But he implicitly understood my rationale for asking it. It seems this damn cycle, has no logic or sense to even be there at all. Would you concur?? Or am i missing something. Tbh I really am adamant Im not, because the chap said the engineer dept/ the whole lot, including input from their design dept in germany ( my insistance has paid off: this is all for me primarily).. had considered, he said, adding a switch to the circuit, for the customer, to turn the f&&&&ng thing ' Off '. All due to me, my problem my idea of the switch, following my reasoning that the frost protection... is fundamentally crackers & of no use other than to make my life full of grief. They agree! I think. thx zoot

Hi joth. That's very helpful & reasonable too. Tbh as they hsve been hopeless understanding their own system, it seems quite clear to me if they've sent countless engineer visits trying to fix something they said they could & would fix.. but haven't.. & furthermore it took someone on here to establish there actually wasn't anything to fix at all- then my confidence of an explanation wasn't with them, but on here! Far more sense on here. Anyway I did what you suggested & called them, & got some info. Amazingly. Their proposal is a " monoblock" instead of the split thing. This means the problem indoor unit... is GONE! Well rather its incorporated in the big fanny unit outside. Woohoo! But... the wretched problem frost protection cycle is in this too. So, I have no idea, really if this will solve my problem, or just shift it away a bit, or if I'll still hear the ruddy same cycle thing just as much. Maybe more. And will the big fanny unit be noisier? Mine has a dampener on it which helps this unit's drone heard through wall much better ( this was a trifling issue jn comparison with the other problem noise/ a token gesture but useful). Thanks, Zoot

Hi Tony, no this is an entirely separate angle. The choice of system, size, is not needed: it will just mean i cannot cope, overloaded by extra information Im not asking about. It must be assumed that calculations have been done, to put in the system i have now. The noise aspect has no bearing or relation on heat loss calculations. With respect, if you could help only with their "...." proposal (understanding it compared to what I have now) Id really appreciate it: this is simply all I am asking for this thread. Ie. Noise issue; they propose a replacement something or other; pls can you help me understand it. Thanks. Zh

This is the " heat exchanger " mentioned in their proposal. Reading it, although ive no idea what it actually is, there is a fair ammount of words connecting directly to the aspect of frost protection, i think, tantalisingly, which seems more than coincidental considering it is exactly pinpoint THIS frost protect aspect, which is the innitiation, of the problem indoor unit, doing what it does so infuriatingly 1 am to 7 am. https://www.vaillant.co.uk/for-installers/products/heat-exchanger-module-42880.html I think this is relevant information for the thread. But I haven't a clue. Thx zh

Hi chaps, had an awful ashp experience so far, but now Vaillant have agreed the following (as ive had no comms after an engineer visit in april.. & i hollered at them last week, just getting this reply): "However, for this reason (they couldnt do anything until next year they said), Vaillant (we) will look to replace your appliance for an aroTHERM/3 with a heat exchanger module. I have no idea of what is proposed you see, need help. So a brief recap. Have an arotherm split with inpossible 1 year problem meaning I have to turn whole thing off 11pm. Problem is noise from the indoor module ( suitcase size, hp pipes go into it, copper pipes come out of it) in my sparebed cupboard, cylinder in this room too. Not slight irritating noise, prominent heard in every room whining pitched motor noise. During heat periods this module is fine, its runs in a " low pump motor gear" lets say. When outside temp drops... the problem starts. At 3*C some frost protection function kicks in. This means this box unit starts an overnight ( coinciding with outside temp drop ) far noisier incessant 6 min on/ 3 min off pump motor noise cycle, not in " low gear " but "highest gear" motor mode. Bbecause it is loud & incessantly on& off it is highly irritating. Bc It is these things plus it starts when you go to bed, it is infuriating. Bc it goes on hundreds of times until the heating kicks in 7 am keeping you from sleeping 3 rooms away, it is so infuriating... I have to turn it all off. Freezing cold until midday then. Tried my best for a year, pressured them, had visit after visit (10x), promise after promise, boards fitted, german xyz ideas considered. Nothing changes. Them adamant its a fault/ to be fixed. So I wait months, then finally snap & holler at them, & squeeze this proposal/ new avenue from them today. But Im into a whole heap of new doo-doo understanding what is being proposed. Let alone if there's any indoor unit at all, if its going to do the same thing etc. Urgh. An utter nightmare. But do I have a solution with this proposal? Is it a different thing? I have no clue whatsoever. Thanks for reading, zoot

Next projects involve mortar... woohoo! And wood. Oh fkaduck some concrete too. Still waiting on the bloomin DG glass for window job, frame ready a month ago. Have to crack on with next mini project then.

Its gonna take me ages to get this concrete thing, all aspects. I mean for eg, my cabin pads.. very runny. My extention foundations i had a heart attack in a rain deluge that day when poured.. & the 48 hrs i fretted while jt set.. seemed to exist underwater. The postcrete.. experienced friend said ' oh just quarter bucke5 of water fine' for one of my posts with 3 bsgs of postcrete in.. leaving it looking a dry powder " ive done it hundred times " he said " dont poke it " was bizarre.. when he went I whacked in another bucket full & stirred it). Just cannae get my noggin around it. I wish there was only one 'right' way to do it!!

Hi Onoff. No but the pin needs to go in the tube, while it sets. Hang on.. you mean stick the pin in, & adhere it to the tube, with foam? Anyway nevermind my matchsticks are holding, but its a bit on a squiff.

It has a hole markc ideal for drop bar, but oddly not so the tube can pass through it. So as i couldn't dare put tube superflush into me 'crete, or crete would overflow into it p*ssing on me parade, ive set my tube just protruding above me 'crete, by thickness of the plate, & levelled a shelf for it. Just then to enlargen the plate hole so it'll fit over it. Prolly wrong idea, but couldnt think any other way.

Stupidly overkill. Now its going off.. where does this 2" square plate thing go? Or am i too late/ leave the bloomin thing off.

Hey great video this. Seems i have many more options than i thought.. & there was i thinking it would all be £500 min to get cctv. Fantastic ideas. Idont see ipad or iOS mentioned but I will trawl for info this ev. Thanks epsilonG.

B'stard job. No idea howmuch water, so quite a soup.. then lost my pipe tube in the soup. Fell off the bloomin pin when i lowered the sod in. I did a huge great big swear echoed off the valley walls see. I needed a shelf for me pipe to sit on. But used cocktail sticks jammed it to the pin to hold it elevated whilst it hsrdens.. hope it'll work. but what a bodge job! @Ferdinand thanks that post idea a better idea for holding the bigger gate in place, once open into the drive.. not doing another pin in soup job ever ever everererer again.

Good timing Peter.. just diving in w' your info now. Thanks. (October now.. but january is round the corner though?) Anyway sorry for my stupidly newbie concrete Q's. The shame..

@joe90 John a basic question if I may.. Im still having trouble understanding mortar, concrete & esp the ingredients. As far as i know, for this small spot/ the pin going into etc like your diagram ( thanks btw, following this ).. i need concrete. I recall making concrete for my cabin pads, but cannot recall the ingredients, or ratios. I can recall we used ballast. Cement. Water. Bit of frostproof. In a mixer. But cannot recall if we used sand too ( & there are two types of sand.. & i have no idea which i have, ideally i forget the sand). Ok so I have cement, do have sand of somesort, bucket of nicked ballast, frostproof stuff. Googling gives me conflicting sand, ballast either/ or info, & gravel.. & Im lost. Am I simply mixing 1:6 cement to ballast ( + splash of f'proof) ? Is the fine grit in the ballast there to act as the sand, so effectively it is a combination of gravel & sand? Thanks, zoot

Understood.. I was thinking you see flat on the gutter, & its unseen. If i can get this up, & its useable vertical, & the white cam too blended in to my white soffit, maybe just nex pto to gutter too.. when both creeps out.. I might be able to catch them, actually recorded ( somehow.. this bit I need to understand yet ). The elusive nugget i desperately need, to at last give to police, to put an end to this 4.5 yrs of harrassment.

Ive missed the last page of replies.. is everyone suddenly on autumn mushrooms? Can i have some? @PeterW hey that sounds fantastic then if it can be iOS compatible. I must do some double checking with their Co.. but this reolink one is top of my list now. Never thought Id be looking at sub £100 for a cctv system ( might be all I need to prevent future incursions, by way of a deterrent only as it'll be visible, & they're proven cowards, unless I can get it up when they're away blend it in high with the white soffit area, & cable tie the solar panel onto my black gutter next to it). Appreciated, will update. Zoot

Interesting this Peter Im trawling the reviews, & get the general gist. Nice & simple, no box thing. My direction is due south too. Only fly in the ointment is whether it can work with my ipad, being my only computer now. Hmm..

Hi Peter, ok sorry I didn't spot your post here. No I havent bought my swann yet. Though it still seems tempting. Interesting idea yours here & flippin cheap!. Battery though... so Id have to scale up me ladder & change its battery every few days tho?

Well I hadn't considered one TonyT, yet, having only just entertained the whole idea ( finally resigned to it ) yesterday. A better angle is perhaps, "this is what I got my eye on" (as it seems fine value for money, & a known brand afaict).. https://www.toolstation.com/swann-1080p-cctv-system/p88773?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&mkwid=s_dc&pcrid=515847200351&pkw=&pmt=&gclid=CjwKCAjwzOqKBhAWEiwArQGwaJIEFkiSbcu8Vhea-l0boZCjmRBxIjd3EMios_p2fdlO2Aeg0Y9aXBoC54EQAvD_BwE&gclsrc=aw.ds#reviewTab
