I have an electric kettle at home I found at a thrift store years ago and paid $3.00 for it. It is extremely useful when I was in need of boiling water for Ramen Noodles. I really don't drink hot tea or coffee so I used it for other things in need of hot water. It whistles when it's ready and uses a standard 120vac outlet so I can plug it in anywhere in the house. I could boil water on the gas stove but that seems like a waste of energy and dumps heat into the house in the summer months for the air-conditioning to deal with. The electric kettle is very convenient. As I recall, it draws 800 watts at 120vac which is not very much power for what it does. It's one of the most useful small electric appliances that I own. ^_^

800W?! That must take hours.


OK that is about a pound of water (a pint or .5 l according to the
directions) Call it 145 BTU assuming you start with 67 F water.
800w/hr = 2730 BTU so it is about 1/19th of an hour, ~3.15 minutes.

I think you can wait 3 minutes for Ramen. (that is about as long as it
takes in my microwave too)

Most microwaves are 800 to 1000 watts, so that makes sense.

Not too long ago electric tea kettles were very common in Canada and
almost unheard of in most of the USA. I remember friends coming to
visit fromthe states back in the sixties buying several and taking
them home as gifts forfamily and friends. They had never seen them!!!
