Default Can I use a plastic loft-type cold water tank for my solar water heater?

the temperature of the water had increased to *beyond* hand-hot. That

So probably not much above 60C or 70C a decent solar collector is
perfectly capable of boil it's circulating water. Plastics do not soften
in a linear manner.

Cold water storage tanks are not designed to hold hot water.
