Top 10 Space Heaters You Can Leave Unattended

One of the biggest fears with using a space heater is leaving it unattended.

There are a host of dangers with this, all leading to fire.

Recently, advancements in the design of space heaters have made them quite safe.

There are now a number of great space heaters that are well suited to being left unattended.

These are space heaters that have advanced safety features that make the heaters far safer and have fail-safes in the event of overheating, tip-over, and more.

Space Heater Safety Tips

Even with a space heater that has enhanced safety features, there are still some best practices that can be used to help further prevent the risk of damage or fire.

How far away should a space heater be?

Most often, you want to keep the space heater about three feet away from anything that can catch fire.

One of the most common ways that space heaters cause issues is by being placed too close to something flammable.

You want to keep your space heater well away from furniture, curtains, and any other material that could easily catch fire.

The placement of your space heater in your home is incredibly important.

Read the user’s manual for any heater you end up buying as it will tell you how far away from flammable materials you need to keep the heater.

What setting should I leave my space heater on?

Set it at low or medium, especially if you are leaving it unattended.

A common mistake people make with a space heater is to leave it on the highest setting.

While this may be tempting as it will keep your home extra warm, this is a mistake.

Most space heaters aren’t designed to run at their highest settings for long periods of time.

Can I use an extension cord for a space heater?

You don’t want to use an extension cord with a space heater.

They often aren’t rated to handle the amount of power that a space heater will put off.

There have been many instances of issues with space heaters that were caused by the extension cord overheating.

Cords are also a trip hazard, which is another reason to try to avoid using an extension cord with a space heater wherever possible.

What kind of surface should I put a space heater on?

For maximum efficiency and better safety, it is recommended that you only place a space heater on a flat, solid surface.

Heaters on uneven surfaces are more likely to tip over and fall and they will also tend to vibrate and make excessive noise if they are placed on an uneven surface.

Space Heater Buying Guide

When buying a space heater, you want to consider a few things to make sure that the option you choose is going to suit your needs.

For a space heater that is safe to leave unattended, the most important things you will want to consider when buying a heater are the price, capacity, and safety features.

Let’s take a brief look at each in turn.


You can get a high-quality, safe, and efficient space heater for less than a hundred dollars, but they can also range up to a few hundred dollars depending on the size, style, and added features. S

etting a budget before you even start shopping is a great way to reduce the amount of time you spend researching things that are out of your budget.


Think about the size of the room you wish to keep warm.

The average-sized room is usually between 150-200 square feet.

Be sure to choose a heater that is at least 1,500 watts to ensure that the heater is powerful enough to heat the room.

Safety Features

Many heaters come with a range of safety features and if you want a heater that can be left unattended, you are going to want to take a closer look at these.

Many space heaters will have a range of safety certifications, such as ETL, SA, or UL.

All of these certifications are given to products that meet strict standards for safety, so look for a heater that has one or more of these certifications.

You will also want to choose a GFCI/GFI plug, which most electric space heaters come with.

This is an additional safety feature at the outlet and is especially useful in homes with older wiring.

Finally, additional safety features like cool-touch surface, overheating sensors that shut the heater off if it gets too hot, and tip-over shutoffs are important features to look for.

Frequently Asked Questions

What are the most important safety features for a space heater?

If you need a safe space heater that can be left unattended, there are two imperative features to look for.

First and foremost, you want the heater to have an overheating sensor.

This will cut power to the heater if it senses that the heater has gotten too hot.

Secondly, look for a space heater that has tip-over shut off protection.

This may be called numerous different things, but this safety feature means that the heater will have the power cut in the event that the heater is tipped over.

This is another key feature any space heater you wish to leave unattended should have.

What type of space heater is safest?

Electric heaters that are infrared or fan-forced heaters tend to be the safest, but any electric space heater with quality safety features will be safe.

Oil-based space heaters, which I didn’t review here, are by far the least safe type of heater.
