We also have a Brevill water heater which will boil a small amount of water e.g. just enough for a single cup or mug. This is far less wasteful of electricity than a kettle in which we always boiled too much water. The Breville boils enough water for a mug in about 1 minute. Again not a huge saving per single use but over the course of a year say, a quite significant difference I would think as we drink huge quantities of tea and coffee!
We have a portable I-R heating panel which we use in the living room when the evenings start to get a bit chilly rather than fire up the central heating. It uses 0.4 kW but has the heat equivalent output of about 2 kW as it directly heats objects in the room (including people!) rather than the air in the room which requires convection to heat up the room. So it's quite economical to use.
