Can You Leave a Space Heater on All Night? Can You Sleep with Heater On?

Can you leave a space heater on all night

According to a 2016 report by the National Fire Protection Association (NFPA), about 54% of heater-related home fire incidents between 2014 and 2018 were caused by heating equipment that homeowners placed too close to highly flammable materials.

This troubling statistic has often left many wondering how safe one can be with heating equipment such as a space heater.

Winter can be beautiful but for the blistering chill that comes with it. The fiercest of them leave no room for escape; the cold just finds its way into your home, either through ventilation or spaces or by simply icing the exterior of your home, causing the interior to absorb the cold.

With winter barely weeks away, homeowners are beginning to wonder how best they can deploy their space heaters and whether it is safe to leave it on all night, especially since 38% of all home fires occur between 8 p.m and 8 a.m?

Can You Leave a Space Heater on All Night?

This usually depends on the type of space heater you have. While we will not advise you to leave a propane space heater or electric space heater on all night due to vulnerable design.

Other types like oil heaters, ceramic heaters and even infrared heaters may be left on as long as they are modern units with built-in safety features.

There are some electric units with modern features like auto-timer, tip-over protection and auto-shutoff in case of overheating, which make them useful overnight as well.

A quality modern space heater is likely to have such features to keep the unit and members of your household safe.

Even with such features, it’s important to keep the heater away from flammable materials to prevent any fire accident. Asides from fire accidents, energy cost is another factor that you need to consider.

Leaving your electric space heater on all night will attract huge power bills that may put a strain on your finances.

Can You Sleep with Space Heaters On?

Yes, you can. This is if the heater is any of ceramic, oil or infrared units with trusted safety features and certifications.

But beyond that, you must’ve done your own part as well to ensure it works safely throughout the night. It is one thing to leave your space heater on all night, but a different thing entirely to sleep while you do.

If you must, ensure you set the unit’s auto-timer to only leave it on for a specific period of time and shut down afterwards. You may set the timer at four hours, so the heater stays on and heats up the space for four hours before going off.

Another thing you must do is to place the unit on the least likely place it can start a fire. If it’s a standalone unit, put it on the floor, away from fabrics like your window cotton or drapings, table cloth, chairs, and so on.

You must also be sure to turn on safety features for extra protection. If you’ve noticed a constant surge in your home or fluctuating currents, do NOT sleep with your electric space heaters on. A surge can occur, causing your heater’s plug to heat up and start a fire.

If you own a propane space heater, do NOT leave it on when you sleep. It is too dangerous because you can have gas leaks, overheating and other situations you won’t be able to control in your sleep. It is like leaving a gas cooker on all night.

List of Top 5 Safe Space Heaters to Use All Night

If you are in hurry and looking for the best options to purchase a safe space heater to use all night, then, please check below.

What Type of Heaters Are Best to Use Overnight?

1. Ceramic Heater

A ceramic heater provides proper insulation that ensures only the interior of the unit heats up while the exterior parts remain cool, preventing any form of fire outbreak. This also makes the heater safe to leave on all night and to touch as well.

2. Oil Heater

Oil heaters are considered the safest on the market. This is because it is enclosed in a metal body that is not flammable. It is unlikely to overheat or cause a fire in your home.

3. Infrared Heater

This is another pretty safe heater that you can leave on overnight. It is a natural method of heating that uses warm rays to heat up people and objects, rather than any flammable energy source. It is more or less like sunlight, so you don’t have anything to worry about.

Guide To Select the Best Space Heater to Use All Night

1. Type of Space Heater

As mentioned in the above section, Ceramic heaters, Oil Heaters and Infrared heaters are proved to be safe to use all night.

Asides from the heaters listed above, the best heaters for overnight use are those modern units with the required safety features to protect you and your loved ones. To use a heater overnight, be sure it is equipped with the following;

2. Auto Timer

You need to be able to determine how long your heater stays on after you’ve gone to bed. This is crucial because the longer the unit stays on, the higher the likelihood of accidents.

Look out for heaters with an auto-timer for up to 8 hours at least. This can help you regulate your heater even when you’re asleep and ensure it doesn’t stay on longer than you desire.

3. Auto-Shut off

Heaters naturally heat up. As they generate heat for your room, their interior also tends to heat up. When overheating occurs, it can lead to a fire outbreak.

This is why you should buy a space heater with an auto-shut-off feature. This automatically shuts down the unit when it begins to overheat and prevents the likelihood of fire accidents in your home.

4. Tip-Over Protection

Another feature to look out for is tip-over protection. If you have little ones or pets who roam at night, it is important that your unit has tip-over protection to ensure it turns off automatically when it is knocked over.

Some units have a 30-degree tip-over protection feature, others have higher or lower tip levels. Just be sure you’re protected.

5. Adjustable Thermostat

If you’re one to leave your space heater on all night, an adjustable thermostat is a no-brainer. This will not only help you preserve energy and cost cut, but will also prevent the risk of fire accidents.

An adjustable thermostat works by ensuring the heater only runs when the figure falls below your settings. This will allow for sufficient rest time, which will enable cooling to take place, as well as cut energy costs.

6. Non-heat Wires

Some unscrupulous manufacturers produce electric space heaters with very inferior wires. When connected and left running for too long, this wire can begin to fail and melt, causing burns in your unit or damaging the outlet it is plugged in.

Furthermore, an inferior wire can start a fire during a surge, posing a threat to life, property and your entire home. Be sure that the wires are sturdy, large and strong enough and have the required length before you make a purchase.

7. Safety Certifications

The best heaters for overnight use must have also gone through several tests and analysis by reputable safety organizations and deemed safe for use.

The heater you intend to deploy overnight should have labels from bodies like Underwriters Laboratory (UL), Canadian Standards Association (CSA) and Intertek (ETL). Such labels tell you the unit has met safety standards.
