Do Heated Blankets Save Money On Heating Bills Or Just Add To Electricity Use

As winter temperatures drop, many households face a recurring dilemma: how to stay warm without sending monthly energy bills through the roof. One increasingly popular solution is the heated blanket—a cozy alternative that promises personalized warmth with minimal energy consumption. But do they actually reduce heating costs, or are they just another appliance drawing power from your outlets? The answer depends on usage habits, home insulation, thermostat settings, and the efficiency of both your central heating and the electric blanket itself.

Heated blankets have evolved significantly from their early, bulky designs. Modern versions are lightweight, feature multiple heat settings, auto-shutoff functions, and even smart controls. With wattages typically ranging between 60 and 150 watts—far less than space heaters or furnaces—they appear to be an energy-efficient option. But does this translate into real savings?

How Heating Costs Add Up

Central heating systems—whether gas furnaces, electric heat pumps, or baseboard heaters—are designed to warm entire homes. This comprehensive approach comes at a cost. According to the U.S. Energy Information Administration (EIA), the average American household spends about $700–$1,200 annually on heating, depending on climate, fuel type, and home size. In colder regions, winter heating can account for nearly half of total annual energy expenditures.

The key inefficiency lies in heating unused spaces. Bedrooms, guest rooms, and hallways often remain unoccupied but still consume energy when the thermostat calls for heat. Additionally, older homes with poor insulation lose significant warmth through walls, windows, and attics, forcing heating systems to work harder and longer.

This is where targeted personal heating solutions like heated blankets come into play. Instead of warming an entire room to 68°F (20°C), you can lower the thermostat by several degrees and rely on localized warmth to maintain comfort. This strategy, known as \"zone heating,\" reduces overall energy demand and can lead to measurable savings.

Tip: Lowering your thermostat by just 7–10°F (4–6°C) for 8 hours a day can reduce heating bills by up to 10% annually.

Energy Use: Heated Blanket vs. Central Heating

To assess whether heated blankets save money, it's essential to compare their energy consumption with that of traditional heating systems.

Heating Method	Average Wattage	Hourly Energy Cost* (at $0.15/kWh)	Daily Cost (8 hours)
Heated Blanket (low setting)	60 W	$0.009	$0.07
Heated Blanket (high setting)	150 W	$0.023	$0.18
Electric Space Heater	1,500 W	$0.225	$1.80
Gas Furnace (average output)	Varies (fuel-based)	$0.15–$0.30/hour**	$1.20–$2.40

*Based on U.S. average electricity rate of $0.15 per kilowatt-hour.
**Estimated operating cost based on natural gas prices and furnace efficiency (80–95%). Actual cost varies by region and system age.

The data shows a stark contrast. Running a heated blanket on high for eight hours costs less than $0.20 per night. In comparison, maintaining central heat for a full house during the same period can cost several dollars. Even using a single space heater in a bedroom is over ten times more expensive than a heated blanket.

“Personalized heating technologies like heated blankets allow users to decouple thermal comfort from whole-home temperature control. When used strategically, they can significantly reduce energy waste.” — Dr. Linda Chen, Energy Efficiency Researcher at the National Institute of Building Sciences

Real-World Savings: A Case Study

Consider the experience of the Thompson family in Minneapolis, Minnesota, where winters regularly dip below freezing. For years, they kept their thermostat set at 70°F (21°C) from November through March to ensure comfort, especially at night. Their average winter heating bill was $220 per month.

In the fall of 2023, they invested in two dual-control heated blankets for their master bed and encouraged family members to wear warmer sleepwear. They lowered the thermostat to 62°F (17°C) at night and programmed it to rise only during waking hours. Over the next three months, their heating bills averaged $175 per month—a 20% reduction.

They calculated that the blankets consumed approximately $1.50 worth of electricity each month combined. Even after factoring in this small added load, they saved $135 over the season. The blankets paid for themselves within four months.

Their success hinged on behavioral change: embracing cooler ambient temperatures while relying on direct body warmth. Without lowering the thermostat, the heated blankets would have simply added to their energy use with no net benefit.

Maximizing Efficiency: How to Use Heated Blankets Wisely

Simply owning a heated blanket isn’t enough to cut costs. To achieve real savings, follow these best practices:

1. Lower your thermostat. Aim for 60–65°F (15–18°C) at night. Pair this with warm pajamas, flannel sheets, and layered bedding for optimal comfort.
2. Use timers and auto-shutoff features. Most modern blankets turn off after 10 hours. Preheat your bed for 15–30 minutes before sleep, then let residual warmth do the rest.
3. Choose low-wattage models. Look for energy-efficient brands with adjustable settings. Some newer models use as little as 40 watts on the lowest setting.
4. Avoid double heating. Don’t run a heated blanket while also using an electric mattress pad or space heater unless absolutely necessary.
5. Maintain your blanket. Regular cleaning and proper storage extend lifespan and prevent overheating or inefficient performance.

Tip: Use your heated blanket primarily during the initial sleep phase. Once your body is warm under regular bedding, you may not need continuous heating.

When Heated Blankets Don’t Save Money

There are scenarios where heated blankets can increase energy costs rather than reduce them:

• No thermostat adjustment. If you keep your home just as warm as before, the blanket adds extra electricity use with no offsetting savings.
• Poor insulation. In drafty homes, localized heating may not be sufficient, leading residents to abandon the strategy and revert to higher thermostat settings.
• Overuse or misuse. Leaving the blanket on all night at maximum heat increases consumption unnecessarily. It also raises safety concerns and shortens product life.
• Old or inefficient models. First-generation heated blankets without thermostats or timers consume more power and pose greater fire risks.

In such cases, the heated blanket becomes a convenience item rather than an energy-saving tool. The financial benefit only materializes when it replaces—not supplements—other forms of heating.

Environmental and Health Considerations

Beyond cost, there are broader implications to consider. Reducing reliance on central heating lowers carbon emissions, especially in homes powered by fossil fuels. Even in regions with clean electricity grids, minimizing energy demand supports grid stability and reduces strain during peak winter periods.

From a health perspective, heated blankets offer therapeutic benefits for people with arthritis, circulation issues, or chronic pain. However, they should be used cautiously by individuals with diabetes or reduced sensitivity, as they may not feel overheating or burns. Always follow manufacturer guidelines and discontinue use if skin irritation occurs.

Frequently Asked Questions

Can I leave my heated blanket on all night?

Modern heated blankets with safety certifications (such as UL or ETL) and auto-shutoff features can be left on overnight if used according to instructions. However, for energy efficiency and safety, it’s better to warm the bed before sleep and turn it off once you’re warm. Continuous use increases electricity consumption and wear on the heating elements.

Are heated blankets cheaper than space heaters?

Yes, significantly. A typical space heater uses around 1,500 watts—about ten times more than a heated blanket. Running a space heater for 8 hours costs roughly $1.80, while a heated blanket costs less than $0.20. For personal warmth, blankets are far more efficient.

Do heated blankets work well in very cold climates?

They can, but effectiveness depends on bedding and room temperature. In extremely cold environments, pair the blanket with insulated bedding, thermal curtains, and door draft stoppers. Lowering the thermostat too much in sub-zero conditions may make it difficult to achieve comfort, so moderation is key.
