Reply to comment by IsMyNameBen in Stanley Legendary 1,9 l, water lukewarm after less than 30 hours by Loobeensky

Excuse me, I'm not a barbarian, I did my research before I've decided to buy Stanley's portable murder weapon to save electricity by boiling one big pot of water a day :D

Yeah, that's also something I wanted to do: to boil it all at night when it's cheaper and have it ready for the next day.

What's your price per kWh, how much energy does you kettle use and for long does it run before it boils a batch of water? How much did the vacuum bottle cost?

I'm really having a hard time seeing how this can have a reasonable payback period considering how little energy we're talking about saving here.
