kettle

Place your kettle on the window, so that the water is "heated" by the sun. This reduces the amount of time that the kettle needs to boil.

To cut down on the expensive boiling of the jug/kettle, why not measure out the number of cups you need (plus a bit extra to cover the heating element) by actually pouring the cup(s) into the jug.

The electric jug is one of the "high user" electric appliances in the home and is very widely used.

It's cheaper to boil the kettle than it is to run hot water. If you're doing the dishes by hand fill the sink up with water from the kettle instead of from the hot water tap.
