As the temperatures fall and winter creeps closer, you’re probably pulling your space heater out of storage. But before you plug it in and get cozy, it’s important to make sure that you’re using it safely. Extension cords can create serious electrical and fire hazards, so you’d better think twice before plugging your heater into one. 

If you’re wondering how to minimize fire danger while using a space heater, keep reading to learn what makes extension cords so dangerous, whether power strips or surge protectors are a suitable alternative, how to safely use a space heater, and when to call the experts at Detailed Electrical for help. 

Why Extension Cords Can Be Dangerous With Space Heaters

Space heaters are high-wattage appliances, which means they use a lot of energy. Their high electrical demand can put significant stress on cords, plugs, outlets, and circuits. The higher the electrical load, the greater the risk of overheating. That’s why they should generally be plugged directly into a properly rated wall outlet, not an extension cord or power strip. 

Let’s take a closer look at why extension cords can be so dangerous.

The Cord May Not Be Rated for the Load

Extension cords come in different wire gauges and ratings. A regular lightweight household extension cord may not be able to safely handle a space heater’s power requirements. Using an undersized cord can cause overheating, creating a fire risk. 

Extension Cords Can Overheat

Even a heavy-duty extension cord can overhead with prolonged high-current use. This risk increases when the cord is coiled, covered by rugs or furniture, pinched, damaged, or run through walls or doorways. 

Connections Can Create Additional Heat

Loose or poor connections at plugs and receptacles can generate additional heat, exacerbating the fire hazard. Additionally, damaged outlets or plugs can make the situation even more dangerous.

What About Power Strips and Surge Protectors?

If extension cords are unsafe for space heaters, what about power strips and surge protectors? Power strips are basically extension cords with multiple sockets, which means that plugging a space heater into a standard power strip is also generally unsafe — especially if you also plug other high-powered devices into it, which can quickly overload the circuit. 

Surge protectors, on the other hand, detect excess voltage and prevent it from reaching your devices. It sounds safer in theory, but in reality, it just adds another potential point of failure and is not a substitute for a properly rated electrical circuit. 

How to Safely Use a Space Heater

Despite all this, space heaters aren’t inherently dangerous as long as you follow these safety guidelines:

• Plug the heater directly into a wall outlet
• Keep the heater on a stable, level surface
• Follow the manufacturer’s recommended clearance from furniture, curtains, bedding, and other combustible materials
• Never cover the heater
• Keep children and pets away from the unit
• Turn the heater off when leaving the room or going to sleep
• Inspect the heater’s cord and plug for damage before each use
• Follow the manufacturer’s instructions and electrical rating

Additionally, you shouldn’t ignore warning signs that something is wrong, including an outlet or plug that becomes unusually warm, burning smells, discoloration around the outlet, buzzing or crackling noises, flickering lights, frequently tripped breakers, or a loose-fitting plug. If you notice any of these signs, turn off and unplug the space heater immediately.

What If You Don’t Have an Outlet Where You Need One?

If you don’t have an outlet where you need one, don’t try to solve your problem with an extension cord. Talk to an electrician to find a solution and determine whether an existing circuit can safely support the heater. You may be able to install a properly located receptacle or even add a dedicated circuit. Just remember that all electrical modifications should be performed by a qualified electrician to ensure they’re done safely. 

When to Call the Experts at Detailed Electrical

Plugging a space heater directly into the wall is always the safest option. You should also be on the lookout for warning signs of danger and call Detailed Electrical when:

• The breaker repeatedly trips when using a space heater
• Multiple high-wattage appliances need to operate on the same circuit
• Outlets are old, damaged, loose, or discolored
• The home has an outdated electrical system
• You need an additional outlet or circuit
