For most space heaters, it is recommended to use an extension cord with a 14-gauge or 12-gauge wire. These wire gauges offer sufficient thickness to handle the power consumption of most heaters, ensuring safe and efficient operation.
Using a 14-gauge or 12-gauge extension cord also helps minimize voltage drop, which can affect the performance of your space heater. With a thicker wire, the electricity can flow more smoothly, providing consistent heat output.
Only use 16-gauge for low-wattage heaters
If you have a low-wattage space heater, such as a small personal heater, you may be able to use an extension cord with a 16-gauge wire. However, it is still important to check the manufacturer’s recommendations for your specific heater model.
Using a 16-gauge extension cord is suitable for low-power heaters because they draw less electricity. This wire gauge is thinner but still capable of safely carrying the lower power requirements of these heaters.
Remember, always follow the manufacturer’s recommendations for extension cord usage and never use a cord with a lower gauge than what is recommended. Safety should always be a top priority when using space heaters.
Cord Length – The Shorter, the Better
When it comes to choosing the right extension cord for your space heater, cord length is an important factor to consider. In general, it is advisable to use shorter extension cords whenever possible. Here’s why:
Avoid extension cords longer than 25 feet
Using extension cords longer than 25 feet can increase the risk of voltage drop, which can lead to decreased performance or even damage to your space heater. Longer cords can cause a drop in voltage, resulting in the heater not receiving enough power to function properly.
It’s best to choose an extension cord that is as short as possible to ensure optimal performance.
Long, thin cords can overheat
Another reason to opt for shorter extension cords is that longer cords, especially those that are thin, can overheat. When a cord is too long and thin, it can create resistance and generate excess heat. This can be dangerous, as it increases the risk of fire or damage to the cord itself.
It is always better to choose a thicker cord that can handle the power requirements of your space heater without overheating.
Shorter 14-gauge cords are safer for high wattages
If you have a high-wattage space heater, it is crucial to use a cord that can handle the load. A 14-gauge extension cord is recommended for high-wattage appliances, as it can carry more current and is less likely to overheat.
These cords are designed to handle the power demands of devices like space heaters, ensuring safety and optimal performance.
