  1. 6:15 In case of water, the "stays flat for a while" is a really long while at 100 °C. Heating 1 kg of water from 0 °C to 100 °C takes about 418 kJ. Boiling 1 kg of water from 100 °C to 101 °C takes about 2247 kJ (or 5 times more than getting it from zero to hundred).

  2. I think this should be described as superior thermal mass instead of proper insulation. Insulation is something you need when outdoors is 40 °C less than indoors for 4 weeks. If you try to do that with thermal mass, the amount of material needed would be insane. If you want good insulation, try PU thermal insulation with aluminium laminate surface. High quality stuff will have interlocking tongue and groove between individual panels to avoid air leaks between the panels.
