It heats up very quickly much faster than the demi not surprising given the 1000w spec but is also much less power efficient theres a motor turned on all the time circulating the water and because no pot you have is going to have a lid thats compatible with the immersion circulator heat escapes from the top as well as the sides since most pots are conductive and so the machine has to work quite a bit harder than the demi
