Can You Use an Extension Cord with a Space Heater? [3 Long Cord Space Heaters]

Extension cord for space heater

A space heater is exactly what its name suggests; a heating device for heating up spaces. Sometimes, it is more focused on people and objects than on the surrounding air in the room.

As a supplementary heater, the space heater- whether convection or radiation- packs a huge amount of power, making people wonder if it can actually work with an extension cord.

We keep getting that question and have decided to address it with this post. Read on to learn more.

Can you use an extension cord with a space heater?

The short and simple answer is No. You should not use an extension cord with your space heater. It is best to plug it directly in a wall outlet and be sure not to plug anything else into the same outlet.

Using an extension cord for your space heater can be hazardous. The space heater is such a sensitive appliance and you must be careful how you power it.

At least 1,100 home fires in the United States are caused by space heaters each year, according to the US Consumer Product Safety Commission.

In fact, the National Fire Protection Association says space heaters account for almost 43% of all home heating related fires and 85% of resulting deaths.

This statistic factors in other items like fireplaces and water heaters. This is why fire and safety authorities warn that you should not take the risk, as extension cords are not designed to handle the amount of current load that a space heater draws.

4 Reasons why you should not use an extension cord with a space heater

Using an extension cord with a space heater is more or less like lighting a cigarette at a gas station. Well, maybe the analogy is quite extreme, but you’ll be putting your home in danger of fire.

Here are 4 important reasons why you should never consider it:

1. The Current is too high for extension cords

This is, perhaps, the primary reason why you should resist the temptation. If there is no wall outlet nearby, you can delay the installation until you fix one.

A regular space heater draws as much as 1,500 watts and between 13 and 15 amps of electricity; that current is too high for your extension cord to handle. Your cable will burn if there is any slight fluctuation.

2. Extension cords will push up currents

The voltage drop caused by resistance in the extension cord is often compensated by an increased power supply. Voltage multiplied by current equals power, and this would mean higher currents which can cause a fire.

In case you still haven’t got the memo; an extension cord and a space heater are two things you should never put together.

3. Efficiency is reduced by your extension cord

With smaller heating devices like a space heater, the goal is to get sufficient heat at lower energy costs.

An extension cord, especially long ones, boosts the resistance and reduces voltage, causing supply to increase, leading to a higher power supply and higher energy costs.

This is because the power source constantly needs to send the amount of power the device is demanding at every given time.

4. Clumsy cables can trip members of your household

Using an extension cord means adding more length to your space heater wiring. If not properly installed, this can obstruct the paths in your home and cause people to trip.

This is very likely if you have kids and pets in your home. Not only can it harm your loved ones, but it may also cause the space heater to tip over.

Can you use heavy duty extension cords with space heaters?

Like we said before, it is better not to use an extension cord at all. Rather, plug the device directly in the wall socket.

However, there are some cases where a heavy-duty extension cord could work with a space heater. You just need to be sure that the cord has a higher amperage than the device.

For instance, if your space heater pulls as much as 15 amps, you’ll need an extension cord that can take more than that. A 14, 12, or 10-gauge cord should do the magic.

Even with such amperage, you still need to watch it. Just be sure it is a quality product from a reputable buyer.
