Why Space Heaters Should Not Be Plugged into Power Strips or Extension Cords?
It is a cold weather reminder that you should NOT plug space heaters into power strips or extension cords. Power strips are not designed to handle the high amperes of current required by the space heater. This may cause overheating and lead to a hazardous fire. For proper safety and life saving protection, plug the space heater directly into the wall outlet (socket). This way, the high wattage required by the heater will be safely managed by the dedicated circuit breaker.
Plugging space heaters into power strips or extension cords can be dangerous and is generally not recommended for several reasons:
Overloading Circuits:
Space heaters typically draw a significant amount of power, and using a power strip or extension cord that is not designed to handle the heater’s wattage can overload the circuit. This can lead to overheating, melting of insulation, and potentially cause a fire.
Fire Hazard:
Space heaters generate heat, and if they are not used properly, they can pose a fire hazard. Power strips and extension cords may not be designed to handle the high current load of a space heater, leading to overheating and increased risk of fire.
Voltage Drop:
Using long extension cords or power strips with inadequate wire gauge for a space heater can result in voltage drop. This can affect the performance of the heater, reducing its efficiency and potentially causing damage to the appliance.
Inadequate Wire Gauge:
Space heaters often require a higher current than other household devices. If the extension cord or power strip has a lower wire gauge than needed, it may not be able to handle the current, leading to overheating and creating a fire hazard.
Manufacturer Recommendations:
Most space heater manufacturers explicitly advise against using extension cords or power strips. Deviating from these recommendations can void warranties and compromise the safety of the appliance.
Code Violations:
In many regions, using extension cords or power strips in this manner may violate electrical codes and regulations. It’s important to follow local building codes to ensure the safety of your electrical setup.
To ensure safe use of space heaters, follow these guidelines:
- Power Strip with Overload Protection: Use power strips that have built-in internal overload protection, and this way, the power strip won’t overload.
- Direct Plug-in: Whenever possible, plug space heaters directly into wall outlets. This reduces the risk of overloading circuits and minimizes potential fire hazards.
- Use Appropriate Outlets: Make sure the outlets you are using are compatible with the space heater’s power requirements. Avoid daisy-chaining multiple extension cords or power strips.
- Use Ceramic Heaters: In the event of a surge protector failure, the heater may overheat and start a fire. For this reason, opt for a ceramic heater instead of an infrared space heater.
- Check Wattage: Ensure that the power strip or extension cord is rated for the wattage of your space heater. Exceeding the capacity of these devices can lead to overheating.
- Inspect Regularly: Periodically check the condition of your power strips and extension cords for signs of wear or damage. Replace any damaged cords immediately.
In summary, plugging space heaters into power strips or extension cords is not recommended due to the increased risk of electrical hazards, fire, and potential damage to the appliances involved. It is essential to prioritize safety and follow the manufacturer’s guidelines and local electrical codes.
FAQ
Why can’t you plug a space heater into an extension cord?
Do not use an extension cord unless absolutely necessary. Using an extension cord with high wattage appliances can start a fire. If you must use an extension cord, it must be marked 14 or #12 AWG, this tells the thickness or gauge of the wire in the cord. (The smaller the number, the greater the thickness of the wire.
Can a power surge damage a space heater?
They only last a second or two, but these surges could cause serious damage to the devices that your family depends on the most — including your heating system
Should a space heater be plugged into the wall?
Electric space heaters must be plugged into walls, never into an extension cord. Keep space heaters level and at least 3 feet from any fabric (curtains, couch, carpet, etc.
Why do you have to unplug space heaters when not in use?
Even when turned off, a space heater can pose a danger if there is a power surge. To be on the safe side, be sure to unplug your space heater when you leave the room and when you clock out for the night
Can you plug a space heater into a power conditioner?
while it might be tempting to simplify your electrical setup using a power strip, the risks associated with this practice are substantial. The answer to can you plug a space heater into a power strip is a resounding no
Why did my space heater melt my extension cord?
Extension cords and strips are not designed to handle the high electric current of a space heater. The heater is too powerful for them and can start a fire or melt them
Is it safe to plug a heater into an extension cord in the UK?
It is not a good idea to plug an electric radiator into an extension lead for safety reasons. Electric heating devices typically utilize plenty of energy when regulating temperature, and significantly fluctuate in power when switching off and on
Can you plug a 2000W heater into an extension lead?
2x 2kw heaters is over 16amp without any voltage drop over the long extension so 13amp is a definite no. Running just one on a 40m lead is not good
