Electric blankets and heated throws warm you directly at around 100W — far less than running central heating or a plug-in heater. They're a classic low-cost winter saver for evenings and bedtime.
Why heated blankets matter
Heating a whole room to stay comfortable on the sofa is expensive. A heated throw lets you turn the thermostat down a degree or two while staying warm, with tiny running costs.
