He must have been reading all your trials and tribulations on here

On of these. https://www.ebay.co.uk/itm/165118285057

The simplicity of a simple switch. I understood how they worked when I was 3, and still understand how they work now. Purely out of interest, how many people here have had cataracts? Certainly made a difference on my view of lighting. I have a vision of a wise sage looking for water, using only rear stays from a bicycle.

The two main advantages that the Sunamp has is the compact size and the low thermal losses. Not sure if that is worth the extra money.

Heard about this on the news. Not just the elderly that get caught. https://www.bbc.co.uk/news/business-15984990

Probably.

I am quite clear with my customers, it is the postman that starts the gossip. I start gossip about the postman.

I have seen it a lot on insulated plasterboard. One place I had to decorate had every screw pop. They expected me to put it right. Told them it was up to the builder to sort it. Put me off the idea if ever using insulated plasterboard.

No mysteries in known physics. But words, in English, can be spelt the same and mean something different, and pronounced different and the they can be spelt different and pronounced the same. It is half the reason people disagree on things, the other half is they don't learn physics.

Not with physics you won't.

Ah. Now we really know what the problem is. Should have kept quiet and not replied, but that is something people from Devon just can't do. Or find a similar sounding village in Cornwall and claim the neighbour misheard. Actually any village will do, we don't pronounce the letters that are put in words.

Wish they would go back to the 70's, system boilers and a tank of hot water. Dead easy to understand. But even that gets complicated as they fit UVCs.

Re the earthing of modules. In the olden days some inverters needed an earth (transformer ones) , other did not (transformerless ones). But that could change between inverter manufacturers. Case of RTFM. Though I think generally, modules are not earthed at all.

I have seen many people move into the village I work in, only to be driven out again by the locals. So of the up country people deserve it, had one move in last year 'because immigrants had ruined the village they lived in'. I warned them with that attitude they would be driven out within 6 months, they were. The is no easy way to be accepted down my end of the county, some people are accepted, others are not, no rhyme or reason, just a small town mentality. If you aren't, and you will know within 12 months of moving in proper, you then have hard choices to make. Legal letters will get binned in my opinion. And we are as noisy as (expletive deleted), and what to know how much everything costs.

How do they monitor the power into and out of the SA?

Could be. Not going to worry about it house will be up for sale soon I think.

It has one of those, but is rubbish or don't work. I am with @ProDave fit a cylinder of some sort.

What is the power rating of the element, they are often under the nominal 3 kW. Just don't leave it unattended to be on the safe side.

There are several grades of stainless. Even our food grade 316 can corrode if we use the wrong cleaner on it. https://continentalsteel.com/stainless-steel/grades/ As for painting, no idea. https://theartsuppliers.com/painting/painting-on-stainless-steel-everything-you-need-to-know/ And some stainless can corrode and fail very quickly in the absence of air.

Fuses do not blow at the rated current (well quick blow fuses might). Just like all things mechanical, it is a combination of temperature and time. A 13A fuse will eventually fail even if it has only has a small load, say 7A after enough time. This is why normal 13A outlets are only rated at 10A continuous load. Adding in an extension lead increases the overall resistance and the current drawn goes up. Why we don't run the whole house of a extension leads and have to put up with fixed position outlets.

Why do people fit these for showering. I am staying up at my Mother's house in Third World Buckinghamshire. Carers turn up, so I nip into the shower, carers fill a bowl of water to wash my Mother's arse, or whatever they do. Flow reduces, water goes cold, then temp becomes scalding, after a couple of minutes all back to normal. This is a 30 kW boiler, and the tap down stairs does not have a great deal of flow. Now I know that accumulators and flow valves can be fitted, but really, combis are rubbish, reminds me of the one I had in my first house back in '84. So things have not moved on in 36 years.

That is the Cornish for you. They say what they like about up country folk. They can probably hide behind the mask of not being a publisher, done the social media sites grand for a decade or more.

That would be like sticking two bi-metalic strips together, back to back. Isn't that basically what glulam is?

You really need to quote the range of external temperatures they were tested at, and the flow rates are useful to know. Temperature is not energy, the CPU on my Raspberry Pi probably gets to 50⁰C, but it wouldn't heat much water in a day.

You can look up current gas prices here: https://tradingeconomics.com/commodity/uk-natural-gas May take a while to filter though to consumers bills because we have legislation to restrict price volatility.
