We have worked out just how much of a lunatic you are !

I think when cold water flows through the pipe, initally the pipe would gain a coating of solid wax within the surrounding liquid, further along where the water has warmed somewhat, some sinking of cooler wax would probably start to happen...if we were talking about a straight pipe through the wax, but with coils and or finned pipes/radiators etc, it would be a bit more complicated.
So, we are largely on the same wave-length -- As much heat uptake pipe/surface as possible, so that it never gets completely waxed over and hence becomes insulated, until the cold flow stops..
I think that effect would be minimised with distributed heating throughout the wax.
We normal mortals won't have that benefit ie. of WetBacks etc. We would be heating during the day ONLY..
It would need more than just the coil in the bottom, since there is no convection to distribute the heat once the wax solidifies, and the conductiviity is fairly low.
But does that matter, IF, we assume that we will eventually melt ALL the wax during the day's accumulation.
No difference to having the pot of wax on the stove.. You see NO EFFECT until the final layer melts and then you have it all hot.. So, in my case , I seek to build a heat-accumululator, as distinct from a transfer/accumulator.
Maybe I can find some used AC radiators for scrap value. I think they would be good for a bit of pressure too.
The only issue will be the TUBE SIZE.. Typically 8 -12mm, but all would need their pipes joined, to give the needed flow rates..
I can likely get my hands on NEW Condenser units, like the ones in Drink-Fridge compressor sleds, but they would be new and hence reasonably expensive, but ALL identical... 30mm square???
Food for thought ??
I have put out a feeler to see if we can buy them reliably via a refrigeration mob...
A square system would be easy to deal with, coz you could just use sheet Insulation..
