This is a little bit off the beaten track, as neither of you would go and buy a combi boiler and fit as it’s a technology that’s unfamiliar to you ( as purchasers not installers ) and you wouldn’t be qualified to do so anyways. Jeremy has DIY’d his after gaining an accreditation from Sunamp, therefore he is competent to do so, joe public is not. Gas fitters received regular addendums to the current regs so they are up to absolute date. Also, they get newsletters from the manufacturers for bugs and fixes / known nuisance faults and dangerous appliance alerts etc. What goes on behind such scenes is NOT public domain. Since becoming involved with Sunamp I have received such updates, I have initiated some responses from concerns I had nearly a year ago, and things changed to that effect and are ongoing as we type. Its early days yes, and yes, in a perfect world, this wouldn’t / shouldn’t happen. The thing that’s missing here is installers / strategic partners of SA are being notified, they are being brought up to speed, they are being told of the bugs and how to correct them and so on, so please let’s not assume they aren’t. ? I for one am ‘in the loop’ and receive such correspondence, and when @Barney12 contacted SA regarding his SA’s getting the 10-month pregnant look he had his question answered before I had a chance to ask myself, just timing, nothing more. They really don’t have that many of these out there in domestic situations, fitted by newbies, and some of those newbies will no doubt not read the manual from cover to cover anyhow, so it would still be easy for this to occur again. Emphasis should be on what’s being done about it, and anyone who’s having units fitted by a good looking bloke can rest assured they’ll be fitted correctly and in accordance with the most recent addendum. You dont take take the cover off a washing machine, as it’s a non user serviceable device. You do take the cover off a SA, but only if you’ve been trained on what to do next. Lets remember it’s a specialist bit of kit, not a set of shelves you can buy and knock up yourself on a Sunday afternoon. When UVCs first came into circulation they were horrendous, ask @MarkA for one and he will confirm that. Then they evolved into reliable efficient units. Bingo. “Progression”. Lets see how SA progress, but it’s still early days. The grievance is that people are paying good money for something they expect to work ‘out of the box’, and I know first hand that @Barney12‘s issues have stopped him boxing off his heating and hot water chapter, but I am fully confident that any issues will be resolved in due course. I do think they should have made the bloody things 30mm wider so the Britney Spears bumps stayed within the confines of the case, rather than being noticeable as they distend. 100% think that was a faux pas on their behalf, but you plonk these in a cupboard and let them get on ( when they’re doing what they’re supposed to that is ) so the it’s not that big a problem as @JSHarris says. @Barney12‘s units, I genuinely think, have suffered from controllers that have not regulated the heat input properly ( nowhere near it in fact ) and that would be a warranty issue imo. SA don’t press release installation information to the public, in the same way other manufactures do not do so either, so nobody would know of these bumps and their resolves if it wasn’t for this thread for eg.

They’ve come along leaps and bounds since the SAPV, but they are still very much ‘hot off the press’. The controls are still quite bland, as Jeremy has shown they needed a customer confidence indicator of some sort to show you it’s alive, but I think they are due to release a new range of controllers, possibly one that is the pv diverter too. Not much known yet but hopefully that’ll be sooner than later.

I’ll tell you how to get around that Not tonight though ?

The feedback from SA was that the good folk in production were putting too much insulation in the upper section which was taking up the room for expansion. The units naturally distend a little, but not that it is problematic afaik, but taking away room for upward expansion meant the lids overly distended to a point that they were cream-krackered. They made these VERY tight, ( I imagine for space saving ), prob an inch too tight, but under normal conditions I’m told it’s ‘normal’. Agree with @JSHarris, where they could do with strapping a corset on it for the panickers.

Just bought from here Link

Yup. Buy the Pre-insulated pipe, chuck it under the hoos and job done ✅

The angles that meet on the external corner of the bath panel bob. Remember your top idea for the toe-tuck angled approach .......? I d’oth my cap.

And then “Space, The Final Frontier.........” aka the compound cuts on the bath boxing in. Youd better get more ale and nurofens in for that

Don’t forget to do your annual inspection and get the benchmark book stamped to keep your warranty in check

Nah, just go to something that’s not water based so the paint doesn’t soften. CT1 / Sika etc will be fine. Don’t forget to fit the top trim whilst the goop is still ‘wet’.

Mosaics all look good. ? Go get ‘em tiger ? ?

The inlet or control group is the multifunction valve that has the 3bar PRedV, the balanced cold draw off point ( where ALL cold feeds for mixer outlets must originate from without exception ( however there is a compliant work-around if it’s a retrofit so ask if you need more info )) and must be within 500mm of the UVC. You can bend that rule a bit, say to locate the group at the attic hatch end of the UVC, but keep it as close as possible. The EV question is easy, carry on with what you want. The absolute rule is no valves / anything between the EV connection point and the EV other than a lockable service valve. Link I routinely fit these as it makes the annual inspection SO much quicker and easier, but good observation of local isolation and some drain points make this unnecessary. Is this a new install ? Have the balanced cold feeds been done from the control group?

Weight distribution, as that lot is sat on a thin liquid screed. The SA’s are NOT light, but still lighter, by nearly half, of the equivalent hot water cylinder.

Buildhub ‘after hours’ sub-forum for self confessed gutter-monkeys ? Count me in !

????????

Not in detail. Just follow the pipe and see where it connects obi wan.

Looks to be in order. Just need to know where the expansion vessel connects and then we may stop ripping the shit out of this. “May”.

As you like to tell me, “keep up”. The other cable looks like it goes around the back of the JB Pen..........

Yes.

Cheers. ?. Sorry, last spoke with him re fixing the same but for his roof structure ?. My bad, scan reading strikes again. Point made though, as now even more critical.

Less yapping, more snapping ??

This is the roof, so shear is deffo a concern. +1 to thunderbolt, chalk n cheese. Roof, but still significant shear. Agree that the concrete screws are hit and miss, but that’s more to do with what they’re being driven into than the fixing itself. @recoveringacademic Ian, is there anything between the timber and the concrete that you’re relying on for purchase?

Chop chop.

So it didn't set like concrete then ? ??
