Why I Believe a Good Extension Cord is Necessary for Space Heaters

As someone who has experienced the dangers of using a space heater with a subpar extension cord, I cannot stress enough the importance of investing in a high-quality extension cord for your space heater. Here are a few reasons why I believe it is necessary.

Firstly, safety should always be a top priority when it comes to using any type of electrical appliance. Space heaters have the potential to overheat and cause fires if not used properly. A good extension cord that is specifically rated for higher wattage appliances, such as space heaters, can help prevent overheating and reduce the risk of fire hazards.

Secondly, using the wrong type of extension cord can also impact the performance and efficiency of your space heater. Cheap or damaged cords may not be able to handle the power needed for your heater, resulting in reduced heating capabilities or even causing damage to the appliance itself. This can lead to higher electricity bills and potentially costly repairs.

Lastly, having a good quality extension cord also provides convenience and flexibility in terms of where you can place your space heater. With a longer cord, you have more options for where you can position your heater without having to worry about being limited by outlet locations.

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

As someone who has had to deal with frigid winters and limited outlets in my home, I understand the importance of finding the best extension cord for a space heater. Not all extension cords are created equal, especially when it comes to powering a high wattage appliance like a space heater. After researching and testing various options, I have compiled this buying guide to help you find the perfect extension cord for your space heater needs.

Determine Your Needs

Before purchasing an extension cord for your space heater, it’s important to determine your specific needs. Consider the following factors:

1. Length: Measure the distance between your outlet and where you plan on placing your space heater. This will determine the length of extension cord you need.

2. Wattage: Check the wattage of your space heater and compare it to the maximum wattage capacity of potential extension cords. Overloading an extension cord can be dangerous and cause fires.

3. Indoor or Outdoor Use: If you plan on using your space heater outdoors, make sure to choose an extension cord that is specifically designed for outdoor use.

4. Safety Features: Look for extension cords with safety features such as grounded plugs, surge protection, and UL certification.

Choose The Right Gauge

The gauge of an extension cord refers to its thickness or diameter. The lower the gauge number, the thicker the wire and higher its capacity to handle electricity. For space heaters, it is recommended to use a 12 or 10 gauge extension cord which can handle up to 15-20 amps respectively. This ensures that there is no risk of overheating or fire hazards.

Consider The Type Of Plug

There are two types of plugs commonly used in household appliances – two-pronged (non-grounded) and three-pronged (grounded). Space heaters usually come with three-pronged plugs, so make sure to choose an extension cord with a matching plug type for safe operation.

Look For Durability And Quality

Investing in a high-quality and durable extension cord will save you money in the long run as it will last longer and perform better. Look for cords with thick insulation and heavy-duty materials that can withstand wear and tear.

Recommended Extension Cords For Space Heaters

After thorough research and personal experience, I highly recommend these top-rated extension cords for space heaters:

1. AmazonBasics 12/3 Heavy-Duty SJTW Lighted Extension Cord – This 12-gauge cord can handle up to 15 amps and is designed for heavy-duty use both indoors and outdoors.

3. Woods Indoor Extension Cord With Tamper Guard – This indoor rated 10-gauge cord can handle up to 20 amps and comes with safety features such as tamper guard covers on all three outlets.

In Conclusion

Choosing the right extension cord for your space heater is crucial for safety, efficiency, and convenience. By considering your specific needs, opting for quality materials, and choosing appropriate gauges, you can find the perfect fit for your space heater without compromising on safety or performance. Make sure to always follow manufacturer’s instructions when using an extension cord with any appliance.
