Bugger. Apologies for my hit-n-run reply. Just very busy atm with about a billion new enquires. I doubt you are alone. Let me explain. With 3-4 bar of incoming pressure, many folk would be jealous of you. Having stonking showers off an unvented hot water cylinder ( UVC ) is easily within your grasp. If you have multiple occupants then you may want / need to consider fitting a cold mains accumulator, but if you are just yourself and the better half then you can discipline yourselves to avoid this cost / space requirement ( for another cylinder the same size as the UVC ) by choosing when to shower / run the dishwasher / washing machine etc.

Superior to what? Insulated where, and how? Back up what you say with some facts please. When did you last hear of a typical internal domestic home wall freezing? Can you give an instance for this, including those which are non-insulted cavity wall dwellings? I've been in / around the construction industry for 3 decades, and not come across this phenomenon yet. How can you defend a foundation which has an under-belly that is continuously purged with an abundant supply of freezing cold air? It has a place, but "superior", definitely not?!

Really? The water wouldn’t be fit for human consumption! The idea is not sound, so buy a few 25L bottles of mineral water and put them somewhere cold and out of sunlight. This one is defo a very bad idea / complete waste of money imho.

Tbh, this is the best course of action, unless Dr.Evil had no further use for his “giant laser”. 😵‍💫💥

How do you value this slab? And do you mean an insulated raft? Or a slab over strip founds?

2nd worst foundation on the market, after just dropping trenches in. Cheap and nasty IMO, cold-ventilated all winter, a choice of the bean counter, only. The beam is 100% insulated 360° round with these products ( Beamshield etc ) including the underbelly, so the ice cold whistling wing blowing continuously under your heated floor for the nasty 3 months of winter won’t be a problem. Bare B&B is complete shart, sorry. Even with trenches the slab won’t go lower than ambient geothermal temp, but b&b will easily go down to freezing temps. Ask a client if they’d prefer to buy concrete blocks or insulation to achieve the same result ( physically). Then ask them if they’d prefer a thermally broken foundation or one which will act like a fridge. If folk are budget constrained then a b&b may be their only choice, but why would you not then improve it any way you could, given that the cost of the blocks / labour / grouting would be in your back pocket to go towards the insulated slab system?

I put a thermostatic mixing valve on the hot outlet of the cylinder, set to 550C, and if the bath tap is not thermostatic, another TMV has to go in to cap the bath at 46oC. "We have the technology"

Optimisers go on the panels. This allows each panel to function independently, and for any shaded ones to never interfere with overall maximum efficiency. Are you looking to DIY this? If not, it's probably a good idea to get an MCS accredited designer to run an eye over your ideas first. You can get these done for free, so well worth the money

Err, "No". @Question, how did this damage occur?

Mine is exactly the same, and only has weed / growth issues around the perimeter tbh. Gravel, for my instance, would probably make things harder to maintain.

You will need something that you are happy with aesthetically, for the bits above ground, and uPVC seems to not attract Roland and his band of merry rats. Below there, you could fit a stainless mesh I suppose. https://www.robinsonwirecloth.co.uk/online-shop/Stainless-woven-12-mesh-1-56-mm-aperture-p52090270?gclid=Cj0KCQiAxbefBhDfARIsAL4XLRqOMHuS0vydAnPgYkfzelJLtknW_PqPk32AoOoBwDIH9EVEe-8IcSAaAmhPEALw_wcB I think paranoia may be worse than the event, but the above would offer some 'protection', perhaps. Whats stopping them coming up under the type 1 / sub-base?

Shirley, you can't be serious

This entire thread summarised in one sentence. If the bath moves, it leaks. I always fit ( fitted ) battens to the rear wall, often with additional support where deemed necessary, and I've never had an issue. @TryC Check out suitable products here; https://www.thewetroomstore.co.uk/wet-room-tanking-kit/ Cheaper than shoplifting.

If your boy has to sell the Cossy to make your bail money, give me first shout lol.

I try explaining this to clients, some smell the coffee, some don't. Thanks for posting this!

And you should know better

You're a changed man. I'll apply a gold star to your profile.

and solar

A slate would be fine, but rodents will chew through solid concrete. Do you have any rodent related issues atm?

Time for a reality check people!!! Get a thermometer and put it in the bath when you think, "ooh, that's just right", eg just before you pass out and then turn the hot tap back off.. Please post that temp here and lets see who ACTUALLY needs these ridiculous DHW temps.

He's an idiot. That cycle should be performed early hours of the morning, ideally in line with an EV car charging ( cheap rate ) tariff, and scheduled as to purposefully avoid scalding someone.

Jesus. I leave you lot alone for a few hours and now we have a bath with a heated blanket. 65°C out of a bath tap is no longer permissible. That’s lunacy. The most a bath hot tap or mixer can have coming out of it is 46°C, above that is an instant b-regs failure. So “NO”.

No pain, no gain "If it was easy......." Temp has zero to do with it. It's about hydraulic resistance, and the resultant flow rate in l/p/m. Most ASHP's require a minimum l/p/m of circulation for them to switch on.

Consider the Frosti tap? https://www.ebay.co.uk/itm/204087125957?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338749401&toolid=20006&customid=GB_11700_204087125957.142841786797~1871722021908-g_CjwKCAiA_6yfBhBNEiwAkmXy53N4cx93hXvWAYSQKsmcwFVHnn45dXSENqXlKwj3ms5UGkKfYsPO0xoC9jcQAvD_BwE Shop around for best prices.
