Tealights & Scented Candles Vs. Electric Wax Warmers

Before we start unpacking the safety aspects of wax warmers, let's take a second to understand how they differ from tealights and scented types of candles. There's no way to effectively manage the heat produced by tealights and candles. Things can go wrong if you leave a scented candle burning long enough. That's especially true with candles in jars.

Leaving a tealight or jar candle to burn for hours heats the container, presenting a fire risk. Jar candles are notorious for this, and ones with liquid in them can even result in exploding candles. The glass heats to unsafe temperatures and has the potential to explode, especially if it falls into the bath or you knock it over onto the floor.

The wax warmer is a much more dependable, reliable, and safer candle alternative compared to tealights and glass jar candles. Wax warmers allow you to adjust the heat source, giving you better control over the operating temperature and lowering fire risk.

Wax warmers come in two models, the incandescent lamp and heating element wax warmers. One uses a bulb to heat the wax, while the other uses a heating element. The heating element version is usually more expensive because some models come with adjustable heating elements and timers, allowing you to set the optimal temperature for the device.

Both models of wax warmers require you to place wax on a plate where the heat melts it, releasing fragrance into the air. Most electric models are suitable for extended use up to 10 hours. Typically, the wax will lose its aroma by then, and you'll need to add new wax to keep the fragrance going.

How Long Can You Leave a Wax Warmer On? – Safety Tips

An old-school rule says you should never leave a candle burning unattended. The heat produced by the candle may cause the wax to spatter, setting fire to flammable objects around it. The same logic applies to scented jar candles, tealights, and wax warmers. However, there's a much lower threat of fire hazards from warmers than aromatic jar candles and tealights.

Let's look at some basic safety tips for running a wax warmer:

Never Leave Tealights or Wax Warmers Unattended Overnight

Don't leave tealights or wax warmer unattended. We've already discussed how they can present a fire hazard. Most tealights burn for around six hours, and a wax warmer lasts up to ten hours. Check on the tealight or wax warmer every so often to ensure it's operating properly.

Keep the Wax Warmer Away From Flammable Items

Place the wax warmer far away from carpets, curtains, upholstery, and other flammable items. It's best to place it on a plate to prevent anything bad from happening.

Keep the Wax Warmer Away From Children & Pets

Ensure you place the wax warmer on a surface that's out of reach of children and pets. Your dog or cat might accidentally knock it over, or kids might find the light fascinating and accidentally spill it on themselves, causing a nasty burn.

Give Electric Wax Warmers a Break

Give the wax warmer a break, don't leave it running continuously for longer than eight to ten hours. Overheating the unit can result in cracks or malfunctions like shorts which present fire hazards.

We recommend buying a model with a timer. Leave it to run for five to six hours. It's better to shorten the operating time and reduce the risk of overheating. The same goes for how long you can leave a lava lamp on and other similar heated mechanisms.

Read the Manufacturer's Instructions

Your wax warmer should come with an insert from the manufacturer explaining the safe operation of the device. Pay attention to the instructions surrounding safe use. The insert should mention the safe maximum operating time.

If the unit doesn't come with the manufacturer's instructions, look them up online. If you can't find them online, look for similar models and see if manufacturers' instructions are available online.

Get a Wax Warmer with a Timer

If you want a safer operation, buy a wax warmer with a built-in timer. You can fall asleep with the unit operating; it shuts off by itself, reducing the risk of fire hazards. As an example, this wax warmer has a timer that can be set at 3, 6, or 9 hours. How long can you leave a wax warmer on? The suggested length is 8 to 10 hours, so that timer is perfect.

Is It Safe to Leave Unused Wax in the Wax Warmer?

When the wax warmer shuts off, the wax will cool and return to a hardened state. Most scented wax blocks lose their fragrance in eight to ten hours. So, the used wax will likely be bland and require throwing away. Don't add a new block to the wax warmer before cleaning it out.

These devices have a design to operate with one block at a time. Adding more wax to the warmer than recommended increases the risk of overheating and spattering, presenting a fire hazard. There's no harm in leaving the cold wax in the warmer; just ensure you clean it out before adding a fresh block.

Tips for Cleaning Wax Warmers

When the wax melts, it becomes fluid and covers the base of the wax warmer. As it cools, the wax hardens. Cleaning the wax warmer is a chore, but you must ensure it's clean before adding a new block. Take the heating element or plate out of the device; it's usually easy to detach.

Place the wax dish into a sink of hot water, and the heat begins to loosen the wax, making it supple and easy to work with. Use a plastic scraper to remove the wax from the heating dish, and clean and dry the dish using a fresh cloth.

Some wax warmers come with a fixed wax plate. This design makes it challenging to clean. You'll have to turn on the warmer to loosen the wax and pour the melted wax out into a bowl. Wipe the remaining warm wax out with a cloth or paper towel.

Don't use knives or sharp metal objects to clean the warming plate. You scratch and damage the surface.

FAQs Regarding Wax Warmer Safety

Let’s cover some more common questions that arise when people ask can you leave wax warmers on all the time. Just because you kept your wax warmer left on for days doesn’t mean it was safe. It just means nothing happened. If you accidentally left your candle warmer on, that's not permission to do it on purpose.

Can I Leave My Wax Warmer on Overnight?

No. Don't leave a wax warmer or tealight candle burning overnight. Most models are good for a ten-hour stretch, but leaving any electrical device unattended overnight is a bad idea. If you want to leave the wax warmer burning while you fall asleep, get a model with a timer.

Set it for a few hours after you go to bed, and it shuts off automatically. It's not like you'll smell the fragrance as you sleep anyway. The timer lowers the risk of fire hazards and saves electricity.

How Often Should You Change the Wax in the Wax Warmer?

As a rule of thumb, you should change the wax after it loses its scent. Typically, it takes eight to ten hours for a wax block to expire and lose its fragrance. Some wax warmers have a bigger wax chamber, allowing you to add two or three blocks. However, it's only safe to run the device for up to ten hours at a time.

If you buy a model with an oversized chamber, you can let the wax cool and re-warm it later when the device cools. The wax should still have some fragrance left in it, depending on how many blocks you use. However, stick to the rule of thumb that one block equals eight to ten hours of fragrance.

Is it Safe to Leave a Wax Warmer on All the Time?

Absolutely not. Manufacturers command us (and even build timers into some of their models) to not use a wax warmer for longer than 8 to 10 hours to avoid overheating or electrical issues.

Does a Wax Warmer Last Longer Than a Scented Candle?

A wax warmer generally last twice as long as a tealight candle. However, jar candles, like the Yankee candle, give you many more hours of fragrance than a single block placed in a wax warmer.

However, leaving a Yankee candle burning for extended periods is unsafe as it presents a fire hazard. You'll have to put out the flame and let it cool after four to six hours before lighting it again.
