2x2 ports & 1x3-port:

That should swell the ranks here: https://www.realhomes.com/news/a-million-plan-to-self-build-in-2020

But with my wiring plan I can have either CH, DHW or both so guessing that feature / SATISFIED wire is redundant?

Numpty question: Why is there a SATISFIED connection on a cylinder stat when there isn't on room stat? As I understand the room stat; clock calls for heat via terminal 4 on the controller and goes to COMMON on the room stat. If bi-metallic strip is closed then the stat DEMANDS heat, fires the boiler via the 3 port valve. Room heats up, bi-metallic strip in the room stat opens, no more DEMAND, boiler stops. So why the need for the SATISFIED connection on the cylinder stat? Why can't it just be a case of bi-metaĺlic strip opens when the cylinder reaches temperature and boiler stops? And why does it go back to 1 on the controller unless it's to do with the unused terminal 2, CH off? I must be not understanding something obvious, apologies! Thanks.

Thank you. Ordered. That other RW3 I pictured above, older model? Seemed simpler for SWMBO to use tbh.

Can I just jump a live to 3 to put HW on constant and have the cylinder stat control it?

Ta. I've found two models with that RW3 designation: &

Good shout. 2xCH + 1xHW. What's a good one?

A sh!t end to today! Supposed to be going out, wife had shower, I went for one and she informs me there's no hot water, "the heating's on all the time". I thought the place was uncomfortably warm today but didn't give it a second thought as in and out all day. I did on passing the downstairs stat turn it down from 30 to 25. Thought maybe she was drying washing on the radiators. The lower controller then that does downstairs CH and HW had really had it. Won't even work resetting it. This was the one I replaced the capacitor in. No problem I thought I'll swap them over and reprogram the one that did upstairs CH to do downstairs CH and HW. Didn't admittedly check whether that was working before I removed it. Couldn't make it up but that's now died as well! Won't reset same fault as the first. What are the chances??? Before I buy two of these is there a better alternative? https://www.amazon.co.uk/Grässlin-Temperature-Control-Switch-White/dp/B079TYWWP5 Cheers (Pumps leaking too one side just noticed when up in the loft. Where everything's been running flat out all day?).

Seems like it's taken all day just to fit a door switch...

Just don't buy Makita G series!

Add in double incontinence for the full experience!

Happened in my Mum's place. A diabetic with mixed dementia she'd been secretly eating KitKats and Battenberg in there and flushing the evidence to hide it. The Dyno man was well impressed. Has the OH got a sweet tooth?

You have to wonder at this in the face of common sense. Who benefits? What's the ulterior motive here? Is it simply that the UK Government is so scared by the potential take up of domestic renewables and losses to their coffers they're applying the brakes?

I was meaning for MCS installers. Genuine people like @binky where they've had to downsize, let staff or apprentices go on the back of the FiT rate cuts. Right or wrong it did spawn an industry just a pity there were so many cowboys.

I was wondering about that. So as panel prices fall could it be installers labour costs will become comparatively higher and the industry can remain buoyant?

Great sound bite: Climate crisis: Huge VAT rise on solar panels makes installation ‘entirely uneconomic’, say experts https://www.independent.co.uk/environment/climate-change-solar-panels-vat-government-fossil-fuels-sian-berry-a8906361.html

There's a thread here might assist:

So...what you're really saying is TWO sachets of cream of tartar?

@nod, these two walls in this cupboard I've to plaster, roughly an area 3.5m2. Now I know I shouldn't even ask but I've half a bag of multi left over from when I did the ceiling and half wall back in August...2018. Stored inside with the bag folded over then shoved in a black bin liner. Could I use it? Would adding some cream of tartar work on "old" plaster? I just HATE waste and LOVE pushing boundaries of what's possible! As the answer is probably NO, I've already bought a new bag! If no good I'll sprinkle on the over site of a neighbour's shed base to get rid. Cheers

Respect. I wouldn't know where to start mapping engines etc!

Case in point, elderly person wants their sockets or light switches moved up / down to be more accessible. You would be daft to run a new cable. Ditto when some muppet drills through putting a picture up etc. Council clerks of works can be right funny sods. We used to do a lot with the PSA and never were there a bunch of more anal gits. Mirrors on sticks checking we'd painted under things! When Part P came in here we had BCOs insisting all the sockets and switches in the EXISTING lounge and diner be moved to the Part M heights when someone had an extension done. Caused untold rows. Dead testing should further prove the quality of the crimp.

I imagine @scottishjohn coming from the auto industry has some horror stories ref crimps getting wet and failing! When I do an "outside" crimp I dip my wire in silicon grease before crimping. mating crimps get the same treatment. As the Welsh Wizard once said "Not lost a patient yet!". Even convinced my motorbike mad mate into doing it.

Copyright, Design and Patent Acts 1988? Presumably by quoting that from the regs I've broken it?

Not going to argue with you. I can point to the exact reg that says this can be done. Anyway the "regs" are not statutory (but can be used as a defence in law). Anyone who said the "good jointed cable" was illegal was likely talking out of their arse and on the fiddle. Disagree entirely ref the first place any problem is going to happen is a well made joint. It won't be a properly done crimp it'll be a screw terminal.
