I've had experience with 'Natural convection flow' when I installed my old 84 gal solar tank.
The hot water pipes are insulated, and I'm not sure if I'll get enough 'flow' to give us anything but lukewarm water quickly.
But, in the middle of the winter and I want to quickly splash some water on my hands, lukewarm is way better that 64F water..

I'll be able to measure the heat loss by allowing convection flow for 8 hours
(at night) while measuring how many kWh used.
The next night, I can close the output cut-off valve and measure the kWh
used without any convection flow. The difference will be the loss.

~~~

I was thinking about the 2x4 idea. The pan is almost 3" deep so, I would need something taller to ramp on.

But, maybe I could grease up the bottom of the pan and then use a 4x4 next to the pan.
I'll take the tank over with the 2-wheeler, balance it on the 4x4,
remove the 2-wheeler and then tilt the tank into the lid and slide it
over while holding up the back edge, so it won't drop on the pan edge.
That way, I won't have to hold the whole weight of the tank..
