East Texas winters are usually mild, but a hard cold snap can roll through Tyler and Longview with little warning. When it does, a lot of homeowners pull a space heater out of the closet to warm up a chilly bedroom or home office. That’s fine, as long as you follow a few space heater safety basics.
Space heater safety starts with where the heater gets its power. The National Fire Protection Association reports that space heaters are involved in a large share of home heating fire deaths. Many of those risks come down to the outlet, the cord, or the circuit behind the wall. The licensed electricians at Evans Air Conditioning, Plumbing & Electrical explain what to avoid.
Why Space Heaters Are Hard on Your Electrical System
Most plug-in space heaters draw up to 1,500 watts. On a standard 120-volt outlet, that’s about 12.5 amps.
Most bedroom and living room outlets sit on a 15-amp circuit, and that circuit usually also feeds other outlets and lights. Electricians size circuits so a load that runs for hours stays at or below about 80% of the breaker rating, which is 12 amps on a 15-amp circuit. A single space heater can use nearly all of that on its own. Add a TV, a lamp, or a phone charger on the same circuit, and you’re asking a lot of the wiring.
Outlets to Avoid
Not every outlet in your home is a good match for a space heater. Skip any outlet that is:
- Loose. If the plug wiggles or slides out easily, the contacts inside are worn. A weak connection heats up under a heavy load.
- Warm, discolored, or scorched. These are signs of heat damage. Stop using that outlet and have it checked.
- A two-prong outlet using an adapter. Older homes often have ungrounded outlets. A three-prong adapter doesn’t add a ground and isn’t meant for a heater.
- Sharing a circuit with other heavy loads. Outlets near a microwave, hair dryer, or window unit may already be close to their limit.
- In a bathroom or near water, unless the manufacturer says that model is designed for it.
- Hidden behind curtains, bedding, or furniture. Heat can build up where you can’t see it.
If your home is short on safe, solid outlets, our team handles plug and switch installation to replace worn outlets or add new ones where you need them.
Cords to Avoid
The cord that came with your heater is the only cord it should use. Keep these rules in mind:
- No extension cords or power strips. They aren’t built for the steady current a heater pulls and can overheat. Plug the heater directly into a wall outlet.
- No damaged cords. Retire any heater with a frayed, cracked, or pinched cord.
- Don’t run the cord under rugs or furniture. Covering a cord traps heat, and foot traffic can damage it over time.
- Pay attention to a hot plug. A plug or cord that feels hot while the heater runs means something is wrong with the heater, the outlet, or both. Turn it off and call an electrician.
Circuits to Avoid
Even a good outlet can sit on an overloaded circuit. Watch for these situations:
- Two heaters on one circuit. Two 1,500-watt heaters will overload a standard 15-amp circuit.
- A circuit that already trips. If the breaker trips when the heater runs, the circuit is telling you it’s overloaded. Don’t keep resetting it.
- Lights that dim when the heater kicks on. That can point to an overloaded circuit or a loose connection.
Not sure which outlets share a circuit? Your panel directory may tell you, but labels are often missing or out of date. An electrical safety inspection can map your circuits, check outlets and connections, and flag any wiring that needs attention. If you rely on a heater in the same room every winter, ask about a dedicated circuit.
A Quick Space Heater Safety Checklist
- Keep the heater at least three feet from anything that can burn, including bedding, curtains, and furniture.
- Choose a heater with tip-over and overheat shutoff.
- Look for a label from a recognized testing lab, such as UL, ETL, or CSA.
- Set it on a flat, hard floor, not on a rug, bed, or table.
- Turn it off when you leave the room or go to sleep.
- Keep kids and pets away from it.
- Test your smoke alarms before cold weather arrives.
What About Gas or Kerosene Heaters?
Electric space heaters don’t produce carbon monoxide, but fuel-burning heaters can. If you use one, choose a model designed for indoor use, follow the manufacturer’s ventilation instructions, and make sure working CO alarms are installed near sleeping areas. Evans installs and replaces CO and smoke detectors throughout East Texas.
If You Need a Space Heater, Look at the Bigger Picture
A space heater is meant to supplement your heating system, not replace it. If one room never warms up or you lean on a heater every cold night, your furnace or heat pump may need attention. A heating repair visit or seasonal furnace maintenance can often fix the real problem. Our post on signs your furnace needs a tune-up covers what to watch for.
