I think this is what I'm getting at, yes. I'm trying to repeat what both Vailant engineers told me, but difficult to do ad verbatim. The manual I was told was unfit for purpose: tbh I'm amazed you gleaned what you have from it, as to me its consistantly double-dutch. Actually not having the huge printed manual overwhelming you, using the online version (I didnt know existed- thx) might be clearer to interpret. I'm really confused by the discussion now! its over my head.

Ah ok. So if i got a 5mm gap running along my boxing.. this stuff not for here then, what instead ?

@joe90 progress so far.. the top step skirt piece not glued in, due to needing to be cut to the door frame/ leaving until.. but other two pieces each side are fixed in. Great idea yours. Funny single skirt bit rhs.. the inny outy old wall prevented putting skirt all along, i offered it up but had to be a banana bending, not ideal to fix in With this pressure wanting it to spring out, or to carpet to surely. Even splitting into 2 bits dinnae work, a big iffset where they met. So compromised, bed will go next to it, and bedside cabinet covers it this side.. rrhs another something covering the vacancy.

That clears that word up then.. as assumed a generic term. Altho i bought 'decorators caulk' so its specific on this tube. Hmm. Ok so i run a bead of it along my painted skirt tops, then what i use my corner rubbery shaping thing, to push it home get off the excess and make it all neat ?

Hi Peter. Thats it, sim registration failed. Ah ok.. no asda, tesco maybe.?

hi Ian. Ok this makes sense as to a plan of action. But as to actually doing it, without being able to Apple register, Im at a loss.

Hi daiking.. easier said than done, I did try, i think someone else suggested going on apple forum to ask, but it needs a mob phone number.. and mine's so old its screen says 'registration failed ' or something, i last used it 2 yrs ago / lives in car for emergencies you see.

I don't understand a few things, one of which is as I just find now, 9.10am. Rads only just 'warm' (btm of them cold-tepid). The controller big number is 19*, my desired carried over from last night, 20*. So heating been on from 7.30am and still on getting it up to 20*. But rads not even hot. I was just in my new extension upstairs room, all new insulation, & standing big-ass-on-bigass-rad.. I could feel a cold nip on my knees w'me long johns on. Room is only tepid, certainly not warm. I sometimes notice this, but only AM. PM when it hasn't had a prior 'idle' block of hours, & I dial in 20* after my stoating, it gets rads hot in 1 hr, my top room gets fairly warm (workshop below- gets actually very pleasant/ toasty even). So a discrepency here, &, I think directly linked to it -not- being designed to be idle at night. Now in here 9.10am today, I'm in a new room akin to one of ProDave's insulated one, but I'm not warm. The thermostat's 2 rooms away, perhaps daftly under normal house rules, on the backside of cylinder cupboard: so actually in a fairly warm spot (defo warmest in house now). I was gonna move it to a convenient place thinking its too warm for it here, to kitchen, as suggested (normally a good place/ access etc) but now thinking its better where it is, as it means the heating won't be going on/ off/ on alot more driving me mad (& costing me), bc my kitchen is a very cold room. It just perplexes me every day this thing. Its like living with an infuriating being you don't know what's round the corner. This might well ring a few bells with some of you.

Yes thanks to MJN.. that's the unit in Q. I'm not saying this unit's rotten, but it is stupidly complicated, & lacking in the overnight setting afaict (& told). The front display is good/ simple enough: like mine you can see its ^ on auto (no timed block periods), the outside temp, big number inside temp, & desired temp. Warning: the manual for this, their engineer told me was not fit for purpose- its like a bible, &, badly translated from german.. almost impossible to use. You swizzle its knob during auto (mine 7.30 am > 9pm) at any time to adjust your desired temp. It has a set-back "day" temp on mine put to 18*. So when I wake 7.30 (when it wakes me) its either at 21* already, because it carries over whatever temp it was on b4 it shut down at 9pm, or 18* if I got fed up with noise at 8.30pm night before & ramped it down. So when I go out AM woodland foraging for stoats & grubs, I try to remember to swizzle the knob so is down again. When I come in late PM, I swizzle my knob up again. The Vailant engineer did all these settings for me, 1st asking what I wanted (plus suggesting xyz instead, I agreed to), including 2x HW periods, just sufficient for my minimal useage, 12-1pm and 5-6pm. He went into flow temps & checked all inner workings. Lastly I asked for overnight period.. no its not got one he said/ not designed to work like this ("got no 3rd setting" were his words) but, I'll put in a set-back temp between 9pm and 7.30am @ 10* he said. So its unlikely to go on overnight is the idea [unless temp drops below 10.. likely in this house in jan.. & unless it just goes on out the blue at 6am, as it did 2x, reasons even engineers had no clue as to why].. but he doesn't usually do this; bc for reasons unknown, others' systems don't wake them up & need a low overnight temp afaict. Another plus for their engineers I should add. I put HW temp to 55*.. suggested by installers on phone. So that's what I have.

Afaik its got a stat in the controller, &, you can put old skool timed block timed periods in. Trouble is its got so much extra that overrides this n that, its even got a flamin outside stat which adjusts (that means it dicks with it) settings too. The one thing is seems to deliberately not have, is an overnight period. I think in germany it is determined from birth you sleep in a warm room 'same as the day' so the engineer brain section is perfectly formed at 17 yrs. Only apes, english pigs, & tent people sleep in cold rooms.

No my point is miossed, again. Ok we have the same unit. Same slpit arotherm whatever XB2. A hyperthetical. Only difference: his boiler is in a cupboard a few degrees warmer than mine. Will there be any difference in the boiler getting up to speed ready to feed the cylinder? very marginally perhaps.. but for all intents & purposes- no/ pretty much the same. Its only onwards from the boiler, the storing HW in the cylinder/ the room temp this is in, the immediate environment the pipes & the rads are in.. all the xyz insulation aspects & air tightness, its only --here-- we can say YES big difference between PD's house (with arotherm split XB2) and mine (with arotherm split XB2).. his rads on infrequently, mine on frequently etc etc. But up to here/ before its passed onwards from the boiler.. pretty much identical time taken, modern house to older house. This is only what I'm commenting on. My kettle doesn't take any difference in time to boil 1L of water between being plugged in my bedroom as it might my (colder) UT room.

Yes of course/ will do tmrw (but a warning: this conroller thing is like a tardis, I'm scared of it, & has been super-tweaked by vailant snr engineer.. its not to be dicked with). I don't think PD or me are neccessarily comparing noise levels- this isn't really a feasable exercise. But ASHP's must share basics. A big fan, & a compressor near it > feeds into the house > into a boiler. I think that's consistant with both?

ProDave I don't have the luxury or money to get someone else. I have had vailant senior engineers put in what this system -not your, yours sounds well designed- can best do. Getting in another installer cannot change the fact that Vailant have designed it to be this way, to not have an extra setting for overnight, & therefore (for some bizarre reason) its meant to be on overnight exactly as it is during the day. I put this to the engineer, I said I think this is what Ive concluded, that it is designed -only- to work this way hence no overnight mode.... & he agreed yes correct. He also admitted its a failing (of sorts) of it. Cannot be changed. Cannot set the thing to go into sleep overnight mode. Its not that another installer can do it/ he can't/ bc its just not available.

I'm specifically not talking about the house here. I'm specifically just talking basic physics. ProDave's fan unit is outside. So is mine. So we have an exact same time it takes this unit to fanny around & do its thing > passing its squished doings into the wall. From here & onto the boiler (& no further) is all I am referring to, with regard to a parity-of-sorts between his & mine. The only difference between his boiler being fed from his big fanny, and mine, is his boiler might be in a slightly warmer room. But the time difference it takes to get up to speed.. vs mine is negligeable (in order then to pass on to cylinder, but this onwards part & then onwards further to the rads I'm not referring to). A very small difference maybe. But a parity-of-sorts. Up to this juncture. Onwards- yes, of course there's a big difference & insulation & air tightness/ his place to mine. But the innitial get the boiler up to speed.. will be almost if not exactly the same.

ProDave I had 2 Vailant engineers in. Both said "there's no 3rd setting, meaning you cant have an overnight setting". Its nothing to do with my installers, the fact that the system is lacking in one fundamental design.. but seems to have a myriad of other settings & complications. A snr Vaillant UK engineer was here, to try & tweak the compressor to make less noise (no change whatsoever).. and.. helped set the damn thing as very best he could so it wouldn't wake me up & put in basic settings (its so damn complicated). He asked what I wanted, which basically was 2 blocks of rads AM & PM, old skool, that's it please Mr. He said it doesn't quite work that way but best idea is to put one loooong block of rads-on @ 7.30 am > 9pm, then using the knob I dial in say 21* after I wake up & then when I go out at 9, remember to spin it back down again. The set-back temp is 18*, he set, because I found this a good daytime 'ambient' temp. So I get in @ 6pm & turn knob up to 21*, or 20*... & rads come on, & automatically go off at 9pm. Right great i say, now Mr can you just set the overnight temp please. No, it doesn't have one. Eh? why not? (no straight answer- I find out the answer myself 2 weeks later). But I can put the set back temp overnight to very low, say 10*.. he says. And this is how its set. Its not -meant- to be used like this. Its designed to be on overnight just as it is in the day, so, its always primed ready to get rads up to speed in 1 hr. Obviously its like my naim amp.. likes to be on & warm (& lit logo is cool). This is the answer I find out myself. Why he said there's no 3rd setting, & how there seems to be 2 setback settings when he said there was only 1, Ive no idea. Its too complicated for me & its own good.

I think Ive made a minor error by thinking 'caulking' goes on after painting, used to tidy-off gaps in skirt tops etc. But just going over 'how to' / 'what is caulk' and other hopelessly basic Q's.. it says caulk before paint. Damn I'm nearing finishing painting all skirts. So what do I do? not caulk at all now? (Is caulk a noun or a verb/ IE is it a collective term for all white tube stuff silicone frame sealants, bathroom perimiters, and skirt gap gubbins?) thanks zoot

Yes understood joe. So, that suggests ProDave's makes at the least some noise within the house too-? Yes I do understand my house is poorly insulated, bar the new extension, compared to I'm sure both your houses. But regardless of how well insulated the house is, if the unit is off for 8 hrs its off. Cold house or warmer house, the outside unit resides in the same place, &, the inside unit won't get up to speed any quicker just bc its sitting in a slightly warmer place @ 6AM ProDave's house vs mine. Both will still take the same time to fire up the system > feed the rads. But you see since its been installed we haven't had even a cold period. Its been constantly mild since late august with o'night temp outside only getting to 4* on just two nights.. my inside temp (where thermostat is) not going below Id say 15* overnight, which might be on a par with a well insulated house overnight in a cold period. But even so, if I have my day temp set to 18* (I like as a default 'ambient' temp) the damn thing has to keep this temp overnight too -in order to be in a decent standby mode to get rads up to speed in 1 hr 1st thing- meaning it wakes up, & wakes me up overnight. There's no extra setting I can put it to for 'overnight' mode to for eg 14*. Why? bc it doesn't like being in this hibernatatative state: so Vailant just go without a setting for overnight/ they just don't let you do it. That's nuts. I don't want rads on at all overnight, but Vailant say I have to. When the cold comes.. that's where the difference seen: ProDave's will take 2 hrs to get to speed, but only need a few dips-in to maintain a nice temp during day.. whereby mine will similarly take 2 hrs to get to speed, but will need many dips-in to maintain a nice temp. Ive yet to know how my system performs, here, when its cold.

.. as seems perfectly normal. So do you set the thermostat to very low overnight in order to achieve this? And do you have to wait an extra hr in morning to allow it to get up to speed from this idle state, so like 2 hrs until you feel room warming-? Mine seems to just not be designed to be used like this.

@Onoff I like that- nice curves. alot of work gone into those bits of mdf blimey. Im gonna have to go w'out the primer.. had to crack on & just have to keep painting the ends. they cant stay brown forever. I hope not to use mdf ever again now tbh/ 2 more cuts.. & I'm done. Next is the door frame/ monday. Im not looking fwd to this- will refresh/ look back at info on here tmrw. @joe90 that's impressive/ neat idea. I have mitre bond for these few skirt bits/ joins. thanks chaps.

No 8x new rads too.

I simply had an immersion tank feeding a bath, 2 sinks. No rads/ no CH.

Hi MJN- ok understood, & I think this is the info condensed enough that I can now pass on to installers, thanks for this.

Are you able to lower the temp for an overnight period.. or do you just keep it on deliberately like the day setting?

@joe90 right Im on board with your idea now.. great thanks for that/ this will be neatest way. Nice idea whoever thought of it too. These bits of skirt not fixed in yet: plan is to fix in all but the top step piece, as the door frame needs going in before this bit. Ive got carpeter penciled in tues you see.. so I need to do frame, plus put these skirt bits in, paint them all.. before. Jeepers. @Onoff yes that's what I thiought you meant- I'm left with the annoying 'end' of mdf tho this way, which seems to remain brown mdf'y even after 2 coats of woodpaint unlike joe's idea/ the visible edge primed. thx

No way not at current plumber rates. I just have to form a plan to put to my installers, rather than demand, certainly not fight them if Steamy Tea's paid for it all. I'm still struggling to understand the dribbles at the mo: this only just sprung on me. They did suggest it -was- related to new pump & it would settle down, so I've got to wait &see if it subsides 1st. Then I can be a bit more forthright if it persists. In the meantime its no longer a (rotten) ASHP now new pump in, & a huge difference thank god (& thx to Vailant I must say- no fuss, they just did it asap). So now its just a compressor-noisy ASHP, with teething issues let's say. ProDave how many rads does yours run, & what kW is it?
