And you also overstated the size of the insulated box Pommie (so it would be better with a small custom fitted box). All round you allowed heaps of safety margin, and I suggested a little more by adding bubblewrap, then a 80W peltier or a couple of 50W units for 100W total. I also agree the brewing heat from a long period of low temp fermentation will be close to nothing.
I have a 12v 6A peltier here and with a good sized heatsink on the hot side its ability to move heat is pretty impressive.
As a test for the OP, you could get a 12v peltier+heatsink and a car battery etc and press it on the side of your 20 litre container and strap it in place with some bungee straps. Then stick a thermometer in and do some simple tests. Blankets will do for insulation for testing.
