Yes point taken. I just need be totally sure before I do something, Im a newbie & it takes me 10x time to research & then do. I say this often. It implies please be patient (& most are- who Im very grateful to). I have also repeatedly said: the installers cannot be contacted (have in fact been let go by the Co who employed them- but even this Co is worse- cannot be contacted either). So I have only one avenue- Vaillant. But as they keep threatening £90 call out charges, I must try establish if anything is at fault 1st, thoughrally sure, hence needing alot of advice from those with ashp's. And multiple faults too = alotta advice. This is not a 'normal install' being via a grant. If it was, the installers would likely (if Id chosen well) have been contactable. At least I have a 5 year warranty by Vaillant accounting for 8x visits foc (but 8x?! & still not fixed?! wtf). But even with this, I am told £90 call out charge IF ylou see they 'find nothing at fault'. Might explain why Im needing so much help & asking so many Q's. thx zoot.

I said I'm stalled until I can determine what this unusually low flow temp reading is. No point continuing measuring rooms, rads, xyz...... if the damn thing has another fault, some huge temperature defect is there. If someone could tell me what they find (flow temp, measured at source/ pipe) vs what their setting is/ therefore might be normal to see/ it would be very useful. @joe90 perhaps or @ProDave who as I recall have ashp's? You contributed -nothing- to this thread or any of mine ever pocaster. Nothing. just constant, incessant sniping interjections or, like this ^ occasionally just repeat what someone else says. One reason its this long... is 5 pages full of these posts.

Can't you offer any help instead, can you not understand my post? Anyone who has a ASHP & able to get a temperature on pipes: any chance you could tell me what you find your flow temp is on pipe, & its set to? IE if you might find a big drop like I do of 20*C. thanks. zH

What I'm trying to do TBC, is establish if this sanding this door edge by maybe 1 or 2mm (twattish- yes possibly/ I am a newbie) makes any difference at all. On 1st thinking yes it does (like Onoff is so angry about), because usually you attatch a door hinge to this sanded door edge. But I'm not. I'm using hinges that attatch to the door -face- instead; so doesn't it mean that now my twattish door edge sanding, is in fact of no consequence after all? Its -this- that I'm trying to "picture" this door once opened & closed/ how these type of 'unusual' hinges might work with sanded edge. thx zH

At least my jokes sometimes are understood. phew again.

Ok. I was just asking the logical Q of whether any point continuing with -any- test if its so clear I might have a flow temp problem. Which seems only what I can think presently, & joe seems to concur from reply only just now, & concurred too if folks were saying 'Yes! you should be getting 55* on your rad pipes too!' when I asked. So you say yes there is, the 55* flow temp figure might only relate to -one- rad, so close all off bar one (is what I think is your reasoning here) & re-measure. Do you know that flow temp is only at its 'max' with a single rad & its normal to see a significant decreaces in flow temp once a normal ammount of rads running to-? Maybe by measuring your own & finding the same happens? Can I ask what your flow temp is, what you find immediately on the pipe exiting your boiler (assuming maybe a similar no. rads running/ IE not doing a 'single rad test') ?

Reasonable- but only you seem to be angry about including discussion on my CH woes here (it was installed during & is intrinsically part of my extention if you ask why its inclusion in 'extention- last stuff'). So why the need to be so desperately wanting to close someone's thread when it's proving invaluable to doing my last extention xyz like 'the enforcer'? Seems rather nasty in my opinion, rallying support against me as youve done before iirc. Just calm down & let it be.

thank god that germs joke was understood is all I can say. phew! Now we are on the same page- cheers for the hinges sketch. Yes the bow is effectively like your pic, concave. I also shaped/ sanded-off the door a couple of mm's to 'fit' this bow profile... but only half-managed to do this. But have I c*cked up my hinges all in a line on the door edge doing this-?? * The only spanner in the works, the only reason I cant just follow your clear steps there... is because of my frame-side hinge placement, being not accessible from the frontside with door offered-up. If I was fixing to where the architrave is (so the hinge is flat 180*) next to the door fixings, the frame hinge would be accessible & I could see/ mark fine. But cos my frame hinges on the other side of door: means --I think-- I have really to fix hingrs to the frame 1st. Then put door in, offer it up. Fix hinges to door 2nd. *This is causing me grief trying to figure out how my hinge offset will work, plus fixing them 'wrongly' on frame first/ door 2nd.. without JFDI 'winging it'. Which is almost where I'm at cos my brain's in a fug over it.

Good. Thanks, that tallies with my logic. And I have in fact sent yet another email to Vaillant renewables dept about this. At the moment I have 4 reasons/ coinciding 'issues'/ all the same from install august/ I'm emailing Vaillant about. So As well as trying to answer the help on here Im also having to tackle Vaillant again, again, again, relentlessly about faults, for 7 months Ive been doing this. Just -this- is exhausting. 1. Night noise continues overnight/ heating comes on when room temp 12.5*, 2. Leak continues (I saw today- installer fault I know this, but impossible to get onto them let alone -another- visit. So I give up with this). 3. Delay until rads suddenly get hot 8am, nothing/ no rad heat at all from 6.30 to 8am. 4. Poor rad performance/ flow temp seems 20* off. Until I can get no.4 "fixed" I don't see it logical to continue with BTU figs, rad tests. And I don't see this happening for months, if ever, as Vaillant will say its normal to expect this 20* drop (probably) or give excuse after excuse I can't decipher.

Absolutely understand this MJN. So, now the Q (which sits like a millstone) is -why- I seem to be measuring 35* flow temp from the box thing if 55* is put in the system. And does reading the temp at this particular pipe getting 44* one day, 35* on multiple readings over 2 following days.. suggest my flow temp can be called 35* at all? (or maybe 44*, even if I read this only on one occasion?!). And why I find these temp disparities at all?

I need to get back on track, please. @PeterW please can you give thoughts on my 35*C flow temp- as far as I can establish that is my flow temp, from most of my 5x temp readings where you told me to do it using your diagram. If me & Vaillant guy put in 55*C (& assuming its still in there, Ive asked Vaillant to tell me & waiting on a reply).. does this suggest to you I have (another) major fault? & if so, does it seem n/a to continue on with individual rad temp tests & BTU findings?

Oh for goodnessv sake Onoff. Nitpicking grammatical errors when its perfectly clear what my intent was, is the most infuriating thing of all to contend with. Gonna get annoyed its has no apostrophe? or gonna is an abbreviation?? its a build forum not a literature forum!

Yes I got that. Mine was a joke back. But even this was misunderstood..!!! Nevermind, but it prooves my point tho. Meaning -will- be lost in translation -many times- on threads. Just acceptance is the key. Eg. I will say something Peter interprets not as I intended, reply, & I am totally confused/ have no clue about the reply. Peter will say something I interpret not as -he- intended, & reply, he is irritated as it seems I'm not listening. Jfb, Roundtits, PeterS understand this & make it super clear to read their posts. But I can't expect that of most. That's one 3rd reason thread is looong. One 3rd is my infuriating CH fitted -during- extention last stuff is protractedly impossible to determine what is 'wrong' if anything is, who is responsible if it is. One 3rd is bc it takes me 10x the time to do a job you could.

Same fir me? doesn't make sense.

Waiting too: for Onoff's germs to go off it.

Yes of course. But look I'm stuck right now. Peter's told me 1st up get flow temp at 'the box thing' under/ pipes. Makes alot of sense to do this 1st. I get readings 20* from what I was expecting/ from what is dialed in. I'm confused. I repeat the readings, get 3x different readings. I'm even more confused. Until I can get replies about this 35* flow temp (afaict it is) & establish A) f this needs to be got to @ 55*C in order to then continue on & test the rads.... I'm kinda stuck not knowing my ass from elbow, certainly unable to see point just yet to continue on with individual rad temps. But everyone just assumes, bc I'm not giving the rad temps that I can't be arsed, or I refuse to do it. I'm waiting & in the meantime, I'm trying this tricky door fit (for me tricky, 10x the time it takes you etc).

Yes, same here, I cant understand alot of the replies for exactly the same reasons! (tbh its this that's equally the reason I get confused as anything that's said I can read clearly!) But I take it on board as the norm for communicating (comms- is that such a 'weird shorthand' ?) in boxes of text one to another. No-one's diction, grammar, shorthand is the same as the next person's. So innevitably -I- get annoyed at -your- diction & grammar equally as you do mine. But I just don't feel the need to vent it out & call people vile names though. zH

Exactly. @TonyT As I'm a newbie Ive said many times, it takes me 10x the time to understand, 10x the time to build X. And I warn of this so poeple aware it'll take me alot longer. As to the CH (only part of thread titled "Extention last stuff" like my door.. but you want to close down) I haven't refused to say what it is, refused help but he very opposite. Ive said it is (an extremely problematic hence many pages) a Vaillant split 7.5kW (or Peter wouldn't have helpfully put up an exact diagram would he). And Ive been grateful for the help, said so alot, even in disagreement I'm still grateful for the input [we agree not FFPurpose, but polar opposites as to who is responsible: hence healthy argument: & argument normal to have bit of frustration]. Humour might not tickle everyone, its the most subjective thing, but always worth trying to add IMO. If my unit's the size of an udder with 4 pipes coming out below, then I'll call it an udder (& joe can amuse us by adding a pic bc Onoff didnt know what an udder was). And if Im trying to describe my big rad the easiest way, its a loooong rad. So what. Just let it be. zh

@Onoff i get you idea of centeline, mid ledges etc spot on, & all 3 marked on door.. but my plan was after this, to fit hinges to frame 1st. I think your reply with 3 useful pics, is to fit ( as is usual, understand this) hinges to door 1 st ? Now bc of this damn bow in of frame, i think fitting hinges frame 1 st is advantageous, and your way/ usual way is at a disadvantage. But i cant remember why. Bllx. Something to do with correct gaps and door opening right im sure was thinking. Can you make any sense out of what i cant actually remember?!

Yes theres a leak from its DHW flow pipe no.4. No-one gonna number the teets for me? come on not alot to ask. Anticlockwise (ie the -udder- way round).. 2,3,4,5.

That's also very good. Many thanks for the rad key Onoff.

Damn now m confused again. Thought i had it then. Both you and onoff say to shift or shape the frame to fit the door? But frames bin in for ages, painted, architrave on. I dont see how i could shift it even if it wasnt painted. But maybe im not getting what you mean by recess in the frame. thx zh

But alignment with the door, in my case, or the frame, having this bow in its midrift? I think you mean its a must on the door.. irrespective of what the frame contours might be, in which case i need to sit my hinges on the frame, above and below my 3 mm recessed mid hinge, as i 1 st thought.. rather than recess them all in meaning the disparity remains.

No ok. Typical issues with box of text to try say what i mean. But i think joe gets what i mean.

I know where the bow is, as said in middle of frame hinge side, concave. But I cant undo it.. the frame's been fixed in for months, with architrave on. No Ive chisseled in my mid hinge, where the bow is, so now with the other two hinges not chissled in/ resting on the frame.. I can get them all in a line. But is this wrong, or, should I chisel in my top & btm hinges too.. which will mean they're not in a line then, mid hinge 3mm into the door vs the other two: its this: is this ok to open a door with these hinges offset/ not spot-on all-3-in-a-line? maybe it makes no difference to the opening of the door at all. I just cant picture it.
