There are some heavy-duty extension cords that can be used for space heaters, but you have to know exactly what size wire it needs
When it comes to space heaters and supplemental heating during the winter, there are few things more dangerous than plugging your space heater into an extension cord. What most people don’t know is that space heaters are not made to be plugged into anything that can provide electricity. Space heaters draw an enormous amount of power to be used on the highest setting, and most extension cords are not suited for use with a space heater. Let me explain why. Extension cords that are commonly used around the house are made of a very thin gauge of wire. These wires are made for lamps, phone chargers, and other small electrical devices. The amount of electricity rated for the extension cords is very small. However, the amount of electricity needed for space heaters is higher than all of your common extension cords. What is the danger? By plugging your space heater into an extension cord, you are creating a fire hazard. That wire will heat up past the limits, and the wire will begin to melt, which could catch your house on fire. There are some heavy-duty extension cords that can be used for space heaters, but you have to know exactly what size wire it needs. Otherwise, your best option is to plug space heaters directly into an outlet. When it comes to supplemental heaters, you have to make sure that you don’t cause a fire. One of the greatest causes of fire comes from overheating the space heater, which is caused by plugging your space heater into a receptacle or extension cords that were not made for the space heater.
