I guess we have to agree to disagree.the great majority of the heated water would rise to the top

And the cost of the control device, which, if you have a gas boiler, makes it an unprofitable proposition.In terms of grid-supplied electricity, that's obviously correct.
However, if the immersion is powered by ('free') solar-generated electricity, then the only effective 'cost' is presumably the lost payment for exporting the electricity and/or the cost of grid electricity used for something that could have been supplied by solar had it not been supplying the immersion - so the calculation is not straightforward.

True, if one wants an automated system - but (although I haven't thought about this very deeply), provided one has the ability to think, there might well be some much cheaper (albeit less convenient) approaches?For example, £300 to buy plus installation. ...,<link to iBoost>
However, as recently discussed, just as with a 'bottom' immersion, with even a low coil, the great majority of the heated water would rise to the top,

Quite so, but not a lot of that 'working its way down' will have happened when only the tyop few inches of water in the cylinder is fairly hot.That is not what happens.... The hottest water will collect/congregate at the highest point, but then the interface between hot and cooler water, will gradually work its way down the cylinder.
You want to put money on that?That is not what happens....

But a route for actually getting it from A to B might not be - at least, without ripping into the decor.Why? 'Wire' is freely available
I don't really understand what people are arguing about. As you say, it's called stratification, and means that the hottest water will always be in the uppermost stratum. with progressively lower temps in the strata below ... and when the average temp of all the water in the cylinder is relatively low (e.g. not long after the heat source at the bottom was turned on) the water in that uppermost stratum will be much hotter than that lower down.Absolutely no need, the article you just posted, confirms what I said happens. It's known as 'stratification'. Warm/hot less dense water, rises to the top, cooler denser water falls. In a cylinder, the interface between layers, will gradually drift down, as the overall temperature increases..
Sure, but eric seemed to be making a fairly general statement, which is why I asked 'why?'But a route for actually getting it from A to B might not be - at least, without ripping into the decor.
Access over to floors to install the wire is simply not there, so wireless is only option.Why? 'Wire' is freely available
