Calculating!
Im sure we talk about 80Wh, not Watt seconds in reference boiler, setup by Ramset!
But summary still not same , optimal for resistance heating is 1,16 Wh/deg celsius. I use only 1,16 when calculating cop, example: 1,16/0,28 = cop 4,14. This means OU device in this case only used 0,28Wh instead of 1,16Wh for heating one litre water one celsius degree
Also this does not include losses, maybe 10% lost to air and we have also heated walls of our container, if ceramic very heavy, if plastic not so much mass to heat.
