The short answer is no, it is not recommended to use a space heater around flammable materials. Space heaters can pose potential risks if not used properly, including causing fires if placed too close to flammable materials or left unattended. The US Consumer Product Safety Commission advises against leaving a space heater on when you go to sleep or placing a space heater close to any sleeping person.
Choosing the Right Space Heater Size
When using a space heater, it is crucial to follow manufacturer guidelines and choose the correct size for your space. Do not purchase oversized heaters, as they increase fire risk. The general rule for sizing heating equipment is for about every 200 square feet of well-insulated property, you’ll need about 4,000 BTUs (approx. 1,200 Watts) of power in your system. You may require more electrical power for poorly insulated spaces.
| Room Size (sq. ft.) | Recommended Heater Size (BTUs) |
|---|---|
| 100-150 | 5,000 BTU |
| 150-250 | 8,000 BTU |
| 250-400 | 10,000 BTU |
| 400-500 | 15,000 BTU |
Proper Placement of Space Heaters
Space heaters should be placed on flat surfaces that are level, away from tables, furniture, carpet and rugs, and aim for concrete, tile or hardwood floors. They should be at least three feet away from any space heater (or other heat source) for curtains, blankets, books, papers and anything else that can burn. Even walls can get too hot, so give that space heater some room to work.
It is also important to never block doorways or escape routes and avoid high traffic areas where they may pose a tripping hazard. Pets and children should always be supervised around space heaters and not left attended.
Space heaters are only intended to provide heat to a specific area and should never be used to dry clothing or other tasks for which they were not designed.
Types of Space Heaters
Space heaters come in various types, including convective and radiant heaters. Convective heaters, typically circular in shape, circulate air upward and outward and are intended for use throughout multiple rooms or even entire houses. They should not be used in small bedrooms or rooms with closed doors. Radiant heaters are intended to warm only a singular room at a time, often including reflectors or electric fans that are intended to direct heat outward toward people.
When purchasing a kerosene heater, it is important to look out for safety features such as automatic shut-off function, battery-operated (since this negates the need for matches), and Underwriters Laboratories (UL) certification.
DIY Tips for Using Space Heaters Safely
Here are some DIY tips for using space heaters safely:
- Read the owner’s manual and follow all instructions.
- Never operate the heater within 3 feet of flammable materials, such as bedding, drapes and furniture.
- Don’t overload the unit’s power capacity by plugging it into a power strip or outlet tap.
- Designate one wall outlet for heater use only, and check its receptacle regularly for any signs of damage.
- Never leave the space heater unattended, but do leave it unplugged when not in use.
- Keep the heater on the floor in an area away from children, pets and heavy foot traffic.
- Routinely check the unit for hazards, such as loose heating elements or a frayed cord.
- Don’t operate the space heater in a workshop or garage used to store combustible liquids.
By following these guidelines and using space heaters responsibly, you can stay warm and safe during the colder months. Remember, safety should always be the top priority when using any heating appliance.
