Electric blankets are blankets which have an
integrated electrical heati
ng
device and generally put on the top bed sheet, and appearance wise look very
familiar to an ordinary everyday blanket. Electric blankets will typically have
a control device/unit which is used to adjust the amount of heat the blanket
produces. Electric blankets are available in both single bed and double bed
sizes, and the larger blankets very often have separate controls for each side
of the bed. Electric blankets can be used to keep the occupant warm while in bed
or to pre-heat the bed before use. Most modern electric blankets use carbon
fibre wires, and this allows them to work on 24 volts instead of 110/240 volts,
and are therefore considered to be more efficient and safer to use. Another
variation of the electric blanket is an electric mattress or pad, which is
placed below the bottom sheet.
