Why Choose a Small Space Heater?

Small space heaters are perfect for:

• Home offices
• Dorms and RVs
• Workshops or garages
• Supplemental heating to reduce energy bills

Instead of heating your entire home, a small heater quickly warms the area you're using—helping cut unnecessary energy costs.

Types of Small Space Heaters

1. Ceramic Heaters

Ceramic heaters are the most common choice for small rooms. They heat up quickly and cool down fast, making them energy-efficient and safe.

Best for: Bedrooms, offices, kids’ rooms

Pros: ✔ Fast heating ✔ Often quieter ✔ Built-in overheat protection

 

2. Infrared Heaters

Infrared heaters warm objects directly, similar to sunlight. They provide gentle, even warmth without drying the air.

Best for: People sensitive to dry air, small living rooms

Pros: ✔ Natural-feeling heat ✔ Energy-efficient ✔ Quiet operation

3. Oil-Filled Radiators

These heaters take longer to warm up but provide long-lasting, steady heat. They’re ideal for keeping a room warm for hours.

Best for: Overnight heating, nurseries, bedrooms

Pros: ✔ Silent ✔ Safe for long use ✔ More stable warmth

 

4. Fan Heaters

Fan heaters blow warm air and can heat a small room rapidly.

Best for: Quick heat, bathrooms, cold corners

Pros: ✔ Very fast heating ✔ Affordable ✔ Lightweight and portable

 

Do Mini Space Heaters Use a Lot of Electricity?

Mini space heaters typically use between 500 to 1500 watts of power, depending on the model and its settings. On average, most mini heaters operate at around 1500 watts, which is the maximum allowed for portable electric heaters in the U.S.
If you run a 1500W mini heater for 1 hour, it will consume 1.5 kWh (kilowatt-hours) of electricity. The cost of running the heater depends on your local electricity rates. For example, if electricity costs $0.12 per kWh, running the heater for 1 hour would cost about $0.18.
In terms of energy usage, mini heaters are more efficient than heating an entire home because they focus on heating a small space. However, if you run them for extended periods, they can still add up on your energy bill.

Key Features to Look For in a Small Space Heater

1. Safety Features (Most Important for U.S. Consumers)

When choosing a heater, always look for:

• Overheat protection
• Tip-over auto shut-off
• Cool-touch exterior
• UL or ETL certification

These are essential for preventing fire hazards—one of the top concerns U.S. shoppers search about.

2. Heating Power (Wattage)

Most small space heaters range from 500W to 1500W.

• 500–750W: very small rooms or personal heating
• 1000–1500W: most bedrooms or offices

1500W is the standard U.S. maximum for portable heaters

3. Noise Level

If you’re using the heater in a bedroom or home office, look for models under 50 dB.
Ceramic and oil-filled heaters are usually the quietest.

4. Energy Efficiency

To save money on electricity, look for:

• Eco mode (adjusts power automatically)
• Thermostat control
• Timer function
• Oscillation (improves heat distribution)

5. Size and Portability

U.S. consumers often search for compact heaters that fit:

• Under desks
• On bedside tables
• In small apartments
• In RVs

Look for models under 10 inches tall for maximum portability.

How to Use a Small Space Heater Safely

Follow these simple guidelines to ensure safe operation:

1. Place the Heater on a Flat, Stable Surface

Avoid placing your heater on unstable or flammable surfaces like beds, sofas, or rugs.

2. Maintain a Safe Distance

Keep the heater at least 3 feet away from furniture, curtains, bedding, or anything that could catch fire.

Never cover the heater with towels, blankets, or clothes.

3. Use the Heater with the Right Power Source

Plug the heater directly into a wall outlet, never use an extension cord or power strip, as these can overheat and cause a fire.

4. Turn Off When Leaving the Room

Always turn off your heater when you leave the room or go to sleep.

Many modern heaters come with an auto shutoff feature for added security.

5. Keep It Away from Water

Never use the heater in bathrooms or wet areas unless it is specifically designed for such use. Avoid plugging in your heater if the area is damp.

6. Use Only in Well-Ventilated Areas

Ensure proper ventilation when using the heater in a room, especially if it’s a closed space, to prevent carbon monoxide build-up (this is more relevant for gas-powered heaters).
