Still a bit labour intensive, but a lot less so than many of the other common methods .....

You could also use your garden debris, like leaves - the Lord knows I have tons of that from all the trees (I fill a 25kg grain bag every day in autumn)!
Combine that with something like this .....

this one may well be a game changer ....

SO MANY applications where a solar WATER panel cant be used, where this will work PERFECTLY ....

It's a great idea Chris, but it wouldn't work that well for me .... don't know how many others might have a similar usage pattern, but my daughter (when she's here) and myself shower / bath at night and the wife baths in the mornings. That means that our geyser draw would be mostly after dark and the solar would be mostly wasted unless we used a way of storing the daytime power production - that puts us back to expensive batteries or using Eskom as the 'battery'.

It therefore makes more sense for me to go the panel & inverter route with Eskom 'battery'. With this setup even a single panel providing full daylight period benefit will make a huge difference, in my case even more so than the two panels with your suggested setup. Without the extra goodies and one less panel cost set off against the inverter and wave rectifier needed, the overall cost would probably be less as well. :think:

Saw something on Fb where some guys somewhere in Europe now use compost heaps to heat household water.
Concept very simple, simply spiral your pipe through the compost heap, with only moving part being a small pump to get the water to the tap.

The pics are a bit deceptive though: once you look closer you realise the compost heap is contained in a circular wall of weldmesh about seven to eight foot high and 4 to 5m in diameter.
Which is a LOT of compost...
And of course it only lasts for a year or two.

But I still think it's a great idea, with some additional business potential, selling compost to your neighbours and giving them someplace to dispose of their garden and fresh kitchen cuttings...

Not so sure about that Mickey. My dad always had a compost heap at the back of the yard. You could push your hand in it, it was nice and warm but did not burn your hand at all. I guess it must have been 40 degrees or less.
Might heat it up a little bit but not much.

Impressive, I'd say!
