For one person, an electric blanket is usually cheaper because it heats your body directly. A space heater can be the better fit when several people need a small room warmed, but portable heaters have a significant fire record and must never run while you sleep. Neither option is risk-free. Choose an intact, non-recalled blanket with manufacturer-approved thermostat or automatic shutoff, or a certified heater with tip-over and overheat protection, then use it exactly as directed.
The short answer
The right choice depends on what you are trying to warm. An electric blanket transfers heat to one person and the bed or sofa, so it normally consumes less electricity than heating all the air in a room. A space heater warms the room itself and can serve two or more people, but it draws substantially more power and creates a larger portable-appliance fire hazard.
| Situation | Better fit | Reason |
|---|---|---|
| One person in bed or on a sofa | Electric blanket | Direct personal heat usually requires less energy than warming surrounding air. |
| Several people sharing a small room | Space heater | It distributes heat through the room instead of warming only one person. |
| Sleeping | Blanket only when its manufacturer explicitly permits all-night thermostat or automatic-shutoff use | A running portable heater should be turned off before sleep; blanket use is conditional on its controls and condition. |
| Child, older adult, reduced sensation or limited mobility | Use extra caution with either product | Delayed awareness of excessive heat, hot surfaces or a developing fault can increase injury risk. |
| Frayed, scorched, damaged, recalled or second-hand product | Neither | Remove it from service and replace or return it. |
What each appliance actually heats
Space heater: room air and nearby surfaces
A portable electric heater converts electricity into heat and releases that heat into the room. Fans may move warm air, while radiant elements warm objects and people in their line of sight. In either design, the appliance is trying to raise the temperature of a volume of air, not just one occupant. Heat can therefore be lost through doors, windows, walls and ventilation.
Many consumer space heaters are rated at a maximum of 1,500 watts, according to Consumer Reports. The rating is the electrical draw while operating at that setting; a thermostat may cycle the element off after the room reaches its target temperature, reducing actual consumption. A 1,500-watt unit still needs a circuit and outlet capable of handling that load without overheating.

Electric blanket: the person and the immediate bedding
An electric blanket uses resistance wires woven into the fabric to warm the surface touching the user. Because the heat is concentrated around the body, it does not need to heat the entire room to make one person comfortable. This is why a blanket is generally the lower-cost option for an individual sitting or lying still.
There is no universal electric-blanket wattage established by the cited safety sources. Read the wattage printed on the blanket’s rating label or in its manual; twin, full, queen and dual-control models can differ. A thermostat or automatic shutoff can cycle the blanket rather than powering it continuously, so the label’s maximum wattage is not necessarily the energy used over a whole night.
How much electricity each option uses
The calculation
Use this equation for either appliance:
watts × hours used × electricity price per kilowatt-hour ÷ 1,000 = operating cost
Use the rate on your utility bill, including the energy charge that applies to the time of use. If your utility has time-of-use pricing, calculate daytime and overnight hours separately. A thermostat that cycles off changes the hours at full draw, so a nameplate calculation is an upper-bound estimate unless you measure actual runtime.
Consumer Reports’ 1,500-watt example
Consumer Reports’ 2025 example assumes a 1,500-watt space heater running for eight hours. The arithmetic is 1,500 × 8 ÷ 1,000 = 12 kilowatt-hours. At the national-average electricity price used in that estimate, 12 kWh costs about $2.10 for one eight-hour period, or approximately $64 for a month. The monthly figure is an estimate based on that stated average rate and repeated daily use; your local tariff, heater cycling and actual schedule can produce a different bill.

| Energy per day | 12 kWh |
| Estimated daily cost | About $2.10 at the stated national-average rate |
| Estimated monthly cost | About $64 with daily repetition at that rate |
Calculating your blanket’s cost
Look for the blanket’s wattage and multiply it by the number of hours it is actually energized. For example, if a label says W watts and you use it for H hours at a rate of R dollars per kilowatt-hour, the cost is W × H × R ÷ 1,000. Use the wattage of each side for a dual-control blanket if both sides are on. Do not substitute the space-heater figure: blankets do not have one standardized power rating.
When a heater can still be economical
Comparing one blanket with one heater is not the same as comparing whole-home heating. A heater may be reasonable for a short, occupied period in a small, closed room if the alternative is heating an entire home. It is not automatically cheap when left on for many hours, used in a drafty space or operated while nobody is present. Calculate the appliance’s incremental cost and compare it with your home’s heating system and thermostat settings.

Portable-heater fire burden
The U.S. Consumer Product Safety Commission reported that portable heaters averaged about 1,600 fires, 70 deaths and 150 injuries per year during 2020–2022, in a release issued in 2026. These are population-level averages, not the probability that a particular new heater will fail. They explain why clearance, outlet choice and supervision matter even when a heater appears to be working normally.
Electric-blanket overheating and burns
Blankets can also overheat, short or create burn injuries. CPSC recall notices documented 34 overheating reports for MaxKare blankets, including two fires, and 577 reports for JKMAX blankets, including 53 burn injuries. A recall history does not mean every blanket is defective, but it does mean you should identify the exact model and check current recall notices before use.
Controls matter more than the category name
For a heater, Consumer Reports recommends an accredited laboratory safety mark, automatic overheat shutoff and tip-over shutoff. For a blanket, a thermostat or automatic shutoff is useful only when it is installed and used as the manufacturer specifies. A control cannot compensate for crushed wiring, a damaged connector, scorched fabric or a recalled model.

How to use a space heater safely
- Choose a suitable unit. Look for a recognized independent laboratory mark, a stable base, tip-over shutoff and automatic overheat protection. Verify the model has not been recalled.
- Place it on a level, hard surface. Do not put a floor heater on a bed, sofa, pile of clothing or unstable table where it can tip or be covered.
- Create a three-foot safety zone. Keep the heater at least three feet from drapes, furniture, bedding and other combustible materials. CPSC gives this exact clearance to reduce fire risk.
- Use a wall outlet directly. Plug the heater into a properly installed wall receptacle. CPSC advises never using a power strip, and an extension cord adds another connection that can overheat under a high continuous load.
- Inspect before every season. Do not operate a unit with a cracked plug, damaged cord, loose grille, unusual odor, sparking or a control that behaves erratically.
- Keep the airflow clear. Never drape fabric over the heater or block its intake and exhaust. A blocked airflow path can trigger overheating protection or create a fire condition.
- Stay present while it operates. Turn it off when leaving the room and before going to sleep. CPSC guidance is to turn portable heaters off when sleeping.
- Stop after a protective shutdown. If the tip-over or overheat system trips, unplug the heater, let it cool and identify the cause. Do not bypass the switch or repeatedly reset a unit that keeps shutting down.
How to use an electric blanket safely
- Check the complete blanket. Examine the fabric, heating area, wires, controller, connector and power cord. London Fire Brigade advises replacing a blanket with frayed fabric, scorch marks, exposed wires, a damaged cord, buzzing controls or an overheating connector.
- Confirm the model is current. Check the exact model and revision against current recall notices. Keep purchase and model information so you can identify it later.
- Follow the care label. Washing, folding, drying and storage instructions protect the internal wires. Do not fold or tightly crease a blanket while it is energized, and do not use it if the manufacturer says it cannot be folded in a particular way.
- Use the controller as designed. Set the thermostat or automatic shutoff only within the stated range. Never replace the controller with a generic one unless the manufacturer specifically approves it.
- Keep connectors dry and fully seated. A loose or wet connector can heat up at the contact point. Unplug before cleaning, washing or moving the blanket.
- Avoid second-hand units. London Fire Brigade recommends against second-hand electric blankets because age, storage damage and recall status may be difficult to verify.
- Replace old blankets. That guidance recommends replacement at least every 10 years, sooner if any defect appears.
- Decide whether overnight use is permitted. London Fire Brigade says to unplug blankets before getting into bed unless the blanket has a thermostat control designed for safe all-night use. Follow the manufacturer’s overnight instructions rather than assuming every auto-off timer is suitable.
Sleeping: the important distinction
Do not sleep with a portable space heater running. A sleeping person may not notice a tipped unit, blocked intake, hot plug or nearby fabric catching heat, and CPSC’s guidance is to turn the heater off before sleep.

Use it overnight only when the manufacturer explicitly allows all-night operation with its thermostat or automatic-shutoff system, the blanket is intact and not recalled, and the controller and connector remain cool and secure. If the instructions require unplugging before bed, follow that requirement even if the blanket seems normal.
Children, older adults and people with reduced sensation
Anyone who may not quickly feel excessive heat or move away from a hot surface needs additional safeguards. That includes young children, some older adults, people with neuropathy or reduced sensation, and anyone with limited mobility. Follow the product’s age and medical-use warnings, keep controls out of unsupervised reach, and avoid direct prolonged contact with a high setting. A caregiver should inspect the equipment and verify that the user can respond to an alarm, odor, heat or a fault.
A practical decision process
- Define the heated area. If one person needs warmth in bed or on a sofa, start with a blanket. If several people need the room warmed, evaluate a heater.
- Check the use period. For a brief, attended session, either product may fit. For overnight use, eliminate a running portable heater and permit a blanket only under its all-night instructions.
- Calculate your local cost. Apply the wattage-hours-rate equation to the exact label and your utility price. Include thermostat cycling as an uncertainty rather than treating maximum wattage as continuous consumption.
- Inspect condition and recalls. A damaged or recalled product is disqualified regardless of its energy cost.
- Set up the safety controls. A heater needs a stable position, three-foot clearance, direct wall connection and tip-over/overheat protection. A blanket needs intact wiring, a sound connector and manufacturer-approved thermostat or automatic shutoff.
- Reassess the room. Close unnecessary drafts, keep combustible clutter away and stop using the appliance if its plug, cord, controller or casing becomes hot, damaged or abnormal.
Common mistakes and what to do instead
| Mistake | Why it is a problem | Safer practice |
|---|---|---|
| Running a heater through a power strip | A high continuous load can overheat the strip or its connections. | Use a properly installed wall outlet directly. |
| Putting a heater beside bedding or curtains | Combustible material can contact a hot surface or restrict airflow. | Maintain the three-foot clearance in every direction specified by CPSC. |
| Leaving a heater on while asleep or away | A developing fault may go unnoticed. | Turn it off before sleep and when leaving. |
| Folding, pinching or covering an energized blanket | Concentrated heat can damage internal wires or overheat fabric. | Use and store it according to the care instructions. |
| Ignoring a buzzing controller or hot connector | These are warning signs of an electrical or connection fault. | Unplug immediately and replace or service only through the manufacturer. |
| Buying a used blanket without model information | Age, damage and recall status may be unknown. | Choose a verifiable, intact unit and check recalls. |
| Assuming “low wattage” means risk-free | Burns and fires can result from damaged wiring or misuse, not only high energy use. | Inspect the product and use every required control. |
How to tell when to stop using either product
- Unplug immediately after smoke, sparks, a burning smell, buzzing, repeated breaker trips or an unusually hot plug.
- Do not keep operating a heater that repeatedly trips its tip-over or overheat protection.
- Retire a blanket with fraying, scorch marks, exposed wire, damaged insulation, a deformed connector or a controller that heats, buzzes or fails to regulate.
- Do not attempt a field repair, splice a cord or bypass a safety switch unless the manufacturer provides an approved repair procedure.
- Keep the product unplugged while you arrange a return, recall remedy or replacement.
Bottom line for your choice
Choose an electric blanket when the goal is personal warmth for one person and the blanket is intact, certified or otherwise independently safety-marked, non-recalled and approved for the way you intend to use it. It will usually cost less because it heats the body rather than the room.
Choose a space heater when multiple occupants need a small room warmed and someone can remain awake and attentive. Select a unit with tip-over and overheat shutoff, maintain the three-foot combustible clearance, plug it directly into a wall outlet and switch it off before sleeping or leaving. The safer and cheaper option is determined by the heated area, operating time, product condition and controls—not by the product category alone.
