1. Choose a Space Heater With Essential Safety Features
Not all heaters are equally safe. When shopping for a new heater, make sure it includes the following modern safety features:
✔ Tip-over Protection
Automatically shuts off the heater if it falls or tilts—critical for homes with kids or pets.
✔ Overheat Protection
Stops the heater when internal temperatures reach unsafe levels.
✔ Certified Safety Labels
Look for testing certifications such as:
UL (Underwriters Laboratories)
ETL (Intertek)
CSA
These indicate the heater meets U.S. electrical safety standards.
✔ Cool-to-the-Touch Housing
Prevents burns when accidentally touched—especially important for ceramic tower heaters.
✔ ECO Mode & Thermostat Control
Helps prevent overheating and reduces energy waste.

2. Place Your Heater in a Safe Location
Incorrect placement is the #1 cause of space heater fires.
Follow the “3-Foot Rule” at all times:
Keep the heater at least 3 feet away from:
curtains
bedding
furniture
clothing
Christmas trees
paper piles
Best Placement Tips
Use only on a flat, level, non-flammable surface
Keep out of high-traffic walkways
Avoid placing on carpets if the model gets hot underneath
Never tuck the heater inside shelving, cabinets, or behind furniture
Point the heater toward open space, not directly at walls
Avoid High-Moisture Areas
Unless specifically rated for bathrooms, do not use space heaters near water.
3. Always Plug Directly Into a Wall Outlet
Space heaters draw high wattage—often 1500W.
For safety:
Do NOT use:
power strips
extension cords
surge protectors
These can overheat and melt, leading to fires.
Do:
Plug directly into a standard wall outlet
Keep the cord uncovered and uncoiled
Inspect the cord for damage before each use
If your heater’s cord feels hot, unplug immediately.
4. Follow Safe Operating Practices Every Time
✔ Never leave the heater running unattended
Turn it off when:
leaving the room
going to bed
leaving the house
✔ Avoid running the heater 24/7
Even heaters with safety features need downtime.
✔ Set a target temperature
Use the thermostat rather than running “High” constantly.
Models with ECO mode prevent overheating and reduce risk.

✔ Keep children and pets away
Avoid placing heaters within reach of:
toddlers
dogs
cats
✔ Do not cover the heater
Never place blankets, towels, or clothes on top.
5. Maintain Your Space Heater Properly
✔ Clean the air inlet and outlet regularly
Dust buildup can cause overheating.
✔ Inspect the heater at the start of every winter
Check:
power cord
plug
control panel
base stability
✔ Replace old heaters
If your heater is over 5–7 years old, consider upgrading to a safer, more efficient model.
6. Safe Usage in Bedrooms, Offices, and Living Rooms
Bedroom Safety
Never run a space heater while sleeping
Use an oil-filled heater for quieter, more stable warmth
Keep the heater at least 3 feet from bedding
Home Office Safety
Keep papers and files away from the heater
Use a ceramic heater with tip-over protection
Living Room Safety
Avoid placing near holiday decorations
Keep kids’ toys and blankets away from heat outlets
7. Special Safety Tips for Pets & Kids
If you have pets:
Choose a heater with a stable, wide base
Avoid oscillating heaters if pets may bump into them
Place heater in a corner away from running paths
If you have kids:
Look for cool-touch designs
Avoid exposed heating elements
Never place a heater near play areas
8. Signs Your Space Heater May Be Unsafe
Stop using your heater immediately if you notice:
burning smells
smoke or sparks
flickering power
overheating plug
rattling or unusual noises
discoloration on the cord
Replace the unit rather than risk a fire.
9. Final Safety Checklist
Before using your space heater this winter, ensure:
✔ It’s placed 3+ feet from anything flammable
✔ Plugged directly into a wall outlet
✔ Equipped with tip-over + overheat protection
✔ Never left running unattended
✔ Clean, dust-free, and on a stable surface
Following these steps greatly reduces fire risk and keeps your home warm and safe all winter.
