The electrical consumption of a heated blanket depends on factors such as its size, heat settings, and technology. A typical electric blanket might use between 50 and 150 watts of power. To illustrate, a 100-watt blanket used for 8 hours would consume 800 watt-hours or 0.8 kilowatt-hours (kWh). At an average electricity price of $0.15 per kWh, this translates to a cost of approximately $0.12 per night.
Understanding power consumption is crucial for managing household energy costs and making informed purchasing decisions. Electric blankets offer a cost-effective way to stay warm during colder months, potentially reducing reliance on more energy-intensive heating systems. Historically, heated bedding has evolved from rudimentary heated stones and water bottles to sophisticated electric blankets with advanced temperature controls and safety features. This evolution reflects the ongoing pursuit of efficient and comfortable personal warming solutions.
