People often look for ways to heat their rooms during the coldest months of the year. There are several different types of heaters already existing, but they’re not perfect for everyone. One of them is using candles heating power. But how many candles would heat a room? Let us look into it.

There isn’t one right way to solve this problem. Because the heating capacity of all candle types is roughly equal, it is the size (or volume) of the room that determines how many candles you need. If you’re looking for something similar to your space heaters but don’t want to spend $20, then you’d need to put 20 usual candles in place of just one heater.

Not just that, the candle size is important too. For example, one of the smaller plain candles won’t last longer than three to four hours if used continuously.

On the one hand, table candles of standard sizes can burn for up to seven hours. Replacing 20 candles each hour sounds a tad bit impractical. Remembering that this figure is for one room only, you should take into account whether candles would be affordable for you.

Keep on reading because we are going to shed light on all essential aspects of candles heating your room.

How Much Heat Does A Single Candle Produce?

To determine whether or not candles satisfy the requirements of a room, you need to know how much heat they produce. What is the number of BTUs of heat produced or power outage by a candle? One candle produces between 75-85 BTUs (British Thermal Units).

Heat capacity is the measure of the amount of energy needed to raise something by one degree Celsius. For candles, the number is extremely small. Compared to other alternatives like space heaters, particularly when compared a space heater. As far as heat goes, candles emit much less than gas-powered fireplaces.

How Many Candles Would Heat A Room

This figure may change slightly depending on the sample. However, the average power you can obtain from any type of candle is roughly the same, e.g., 80 watts. Generally, it can heat a two-square foot space. Light and heat are two different things. Keeping that in mind, one of the tea light candles can heat 0.2% of a room.

Both can give off warmth, but it’s primarily the heat that you mean when referring to it. Efficiency is another important factor to consider when choosing a heating solution. It’s kind of a measure of energy production. Candles have an energy efficiency of 90 percent.

Light accounts for only 10% of the candle‘s energy, but it makes up most of its appearance. This efficiency is similar in nature to that of space heaters. Efficiency factors explain that even though the light intensities of candles are low, they can provide enough heat and warmth for small rooms.

Do Candles Stand Out In Terms Of Efficiency?

We’ve already discussed why candles and space heaters aren’t different in terms of efficiency; now let’s talk about how these heating solutions are similar. Space heaters use 90 percent of the input energy, which means they convert electricity into heat.

So, candles and heaters aren’t really at an advantage. However, we’ll look at efficiency in regards to costs now. Are candles cheaper than heaters? So are candles cheaper than heating devices? The simple answer is “not really”.

You might wonder why space heaters are so expensive as products and then add up to their energy costs. However, candles aren’t any less expensive than these alternatives.

Candles come in different sizes, ranging from votives to pillar candles, larger candles to tea candles. If you need to place 20 items at a time and replace each one every four hours, you’d need at least 120 per day. You’d also have to be careful not to set yourself on fire.

Heaters are much more durable. You will definitely need to run a cost-benefit analysis of candles.

How Does The Candle Wax Type Affect The Heat Intensity Of Candles?

This factor is pivotal when it comes to using a candle heat source. Let us get into it.

Yes, the type of wax used for candles affects how hot a candle burns and how warm the room becomes. Some waxes melt at different temperatures and burn for longer than others. Each candle wax has different properties. This, in turn, affects the heat generated by the candle flame.

Let us consider two types of wax.

Paraffin Wax

Paraffin wax candles or petroleum-based candles melt at a lower temperature than soy wax because of they fact that it contains more crystals. Wax candles made from soy wax melt at a lower temperature than paraffin wax candles. Besides, it lasts for longer than paraffin. If you want to light a room, you’d want a candle that burns brighter and illuminates better when the temperature drops.

Beeswax

Beeswax melts at a higher temperature than soy wax and paraffin. However, because beeswax is densest than soy wax, it burns for longer than soy wax candles, but not as long as paraffin wax candles. We stumbled upon some scientific research that discusses the potential of beeswax and paraffin as a way to store heat in an incubator.

The results showed that beeswax had a higher latent heat capacity than paraffin, so it could be used for storing heat better. Do you know how to make scented candles with beeswax? Find out here.

Are There Any Alternatives To Candles?

Fortunately, we have alternatives to using candles. One can go for heating blankets, additional warm layers, and mattress covers.

Is It Fatal To Use Candles As A Heating Source?

Using candles for heating is dangerous. When there are too many candles burning at once, they create a situation where carbon monoxide poisoning can occur. Carbon monoxide poisoning may cause severe tissue damage and even death if not treated quickly.

You should always have some sort of ventilation system and a CO detector in your bedroom to avoid any potential health risks from carbon monoxide poisoning.

Final Verdict

You need twenty candles to light up a room. But that doesn’t necessarily mean that using candles is an effective way to get rid of acne. You will need to keep refilling them because they will eventually run out. You will need 120 tea lights to heat a room for 24 consecutive hours. On top of that, you’ll always need to keep an eye on candles that burn down because they get blown out by the wind.

Using candles for heating is impractical. To heat up water for an emergency, I’d recommend using a regular propane gas heater. It’s better than anything else out there. It doesn’t take too much effort to keep a candle lit for an extended period of time, so you might want to consider keeping one at home instead of buying new ones every few days.
