The Importance of Choosing the Best Extension Cord for Your Space Heater

As someone who has had their fair share of experience with space heaters, I cannot stress enough the importance of using the right extension cord for them. It may seem like a minor detail, but using the wrong extension cord can lead to serious safety hazards and damage to your space heater.

First and foremost, using an extension cord that is not rated for high wattage appliances like space heaters can cause overheating and even fires. Space heaters typically use a lot of power, and not all extension cords are designed to handle that amount of electricity. This is especially true for older or cheaper cords that may not have the proper insulation or gauge size.

In addition, using a long or thin extension cord can also cause voltage drop, which means that the electricity reaching your space heater may not be enough to power it properly. This can result in your heater not functioning at its full capacity and potentially causing damage to its internal components.

Moreover, many space heaters have specific instructions on what type of extension cord should be used with them. Not following these guidelines can void your warranty and put you at risk for any damages that may occur.

Lastly, using a good quality extension cord also ensures that your space heater is

My Buying Guide on ‘Best Extension Cord For Space Heater’

When it comes to using a space heater, one of the most important factors to consider is the type of extension cord you are using. Using the wrong extension cord can not only damage your space heater but also pose a safety hazard. As someone who has done extensive research and used various types of extension cords for my space heater, I have put together this buying guide to help you choose the best extension cord for your space heater.

1. Consider the wattage and length

The first thing you need to consider when buying an extension cord for your space heater is its wattage and length. You should always make sure that the wattage rating of the extension cord matches or exceeds the wattage rating of your space heater. This will ensure that the cord can handle the power load without overheating or causing any damage.

Additionally, pay attention to the length of the extension cord. The longer the cord, the more resistance there will be, which can affect its performance and potentially cause it to overheat. It is recommended to use an extension cord with a length of 6 feet or less for your space heater.

2. Choose a heavy-duty extension cord

It is important to choose a heavy-duty extension cord for your space heater as they are designed to handle high power loads and are less likely to overheat. Look for cords with thicker gauge wires (14 or 12 gauge) as they can handle larger electrical currents without getting hot.

Moreover, heavy-duty cords have better insulation, which reduces heat transfer and minimizes any potential fire hazards. They may cost more than regular cords, but investing in a high-quality heavy-duty extension cord will ensure safety and prevent any damage to your space heater.

3. Opt for grounded cords

Grounded cords have three prongs instead of two, with one prong being larger than the other two. These types of cords provide an extra layer of safety by grounding any excess electricity through the third prong in case of a short circuit. Space heaters tend to draw a lot of power, so using a grounded extension cord will reduce any risk of electrical fires.

4. Look for UL certification

Always check if an extension cord has been certified by Underwriters Laboratories (UL). UL is an independent organization that tests and certifies products based on safety standards set by national organizations like OSHA (Occupational Safety and Health Administration). UL certification ensures that the product has undergone rigorous testing and meets all safety requirements.

5. Don’t daisy chain multiple cords together

Daisy chaining multiple cords together is not safe, especially when using them with high-powered devices like space heaters. This practice increases resistance and heat buildup, which can lead to overheating and potentially cause fires.

Instead, invest in a longer heavy-duty extension cord that can reach your desired location without needing additional cords.

In conclusion, when purchasing an extension cord for your space heater, always consider its wattage rating, length, durability, grounding capabilities, and certifications such as UL approval. By following these guidelines, you can ensure safe and efficient use of your space heater without worrying about any potential hazards caused by faulty or inadequate extension cords.
