The thermos kettle is plugged in for 24 hours. Of course, it costs electricity very much. You can open in the water after temporarily turn off the power, because the insulation pot is double insulation, although less than the ordinary thermos bottle, but a few hours is not a problem, a few hours, then heating once, my family is so used. Wish success.

I don't know how hot the thermos is in your house, but you see, my data is not as good as yours! How can you say that insulation will save electricity?!

I'm an electrician! Electricity can be calculated.It takes 10 minutes for heating in our house and 30 seconds for heating every 10 minutes. Then 1 days to 30*6*24=4320s=1.2 hours, see ~ ~ ~ heating 10 minutes of hot water, the daily heat preservation will be heated for 1.2 hours.How much electricity do you use?!
