Celebrity: Dustin the Turkey
Dustin the Turkey has nominated the electric blanket as the best invention of all time.
Before the electric blanket came the bed warmer. This was a metal container, which looked like a frying pan, and would be filled with hot coals to warm the bed up.
Following the invention of rubber; the bed warmer was replaced by the hot water bottle which is still popular today.
The modern design of the hot water bottle is subject to a patent by Slavoljub Eduard Penkala.
An electric blanket contains an integrated electrical heating device which can be placed under the bottom bed sheet or on top of the top bed sheet.
The US Department of Energy’s Office of Energy Efficiency and Renewable Energy puts the electric blanket at the top of its list of energy-efficient small home appliances. Operating an electric blanket for eight hours a night, six months a year costs half as much as operating a space heater for three hours a night in the same time period.
