The cold truth is, No. Candles cannot heat a room in its entirety. Instead, a set of candles will only be able to warm up a space to a certain extent.

The extent of heat would depend on different factors that include;

  • Size of the room
  • Use of insulated blinds and curtains
  • The temperature outside the room
  • Proper home insulation

Now, let’s get real. Using a candle heater or candles for heat can be a great alternative if you run out of fuel or other heating alternatives. However, it isn’t a winter cure as a whole.

Different candles would produce different amounts of heat, depending on their size and wax type.

However, an average tealight candle can produce nearly 32 watts of power. For your information, 30 watts of energy will only be able to heat a space of around two square feet.

So, imagine your room measuring 10×10 feet, which is 100 square feet. For heating this big a room, you’ll probably need 50 or more tealight candles.

As already explained above, the amount of candles you need to warm up a room depends on the size and other features of the room. These features include the room’s insulation, curtains and blinds used, and the type of doors and windows installed in the room.

As already calculated above, one tealight candle can capably warm up a 2 square feet area. So, depending on the floor size of your room, you’ll have to calculate the requirement accordingly.

Generally, the average room size in most states is around 200 square feet. And, to heat a room of this size, you would require (200/2), i.e., 100 candles.

But, now comes the safety question. Is it safe to light up 100 candles in a room to make it comfortable during the winter (when you already have a lot of woolen stuff in the room)?

The answer is absolutely not. Keeping the safety point of view, it is not advisable to use candles for heat. Instead, you should go for other heating alternatives that would also be of help during power outages.

How to Heat a Room with a Candle?

How to Heat a Room with a Candle

Heating a room with a candle requires a technical approach. You have to keep a lot of things in mind while using this source of heating. Therefore, below mentioned is the step-by-step guide to help you heat a room with a candle.

Pick the smallest room to heat with a candle

To start with the process, you’ll have to pick the smallest room because that will be the easiest to heat.

Smaller space will require fewer candles, which will probably be less dangerous. Generally, you should prefer picking up a room that’s not in direct contact with the ground. Instead, choose a one constructed on the first or second floor.

Gather the required Candles (Make sure to add some extra pieces)

According to the size of the room, pick candles that could heat it in its entirety. Ideally, you’ll need one candle per 2 square feet area. So, instead of placing candles individually, create the flower pot arrangement, under which you can place 4-8 candles together.

Technically, four tealight candles can heat up the exterior of a terracotta pot up to 130 degree celcius. And, a single candle can achieve 53 degree celcius. So, depending on the amount of heat you wish to generate, choose the number of candles accordingly.

Close the cracks in the window frame

To warm a room with candles, you’ll have to seal all the cracks in the window and door frames. Even the slightest open space between the windows would spoil the whole game. If the space is not sealed adequately, you’ll never be able to heat a room with candles.

Reverse the direction of your ceiling fan

When you reverse the direction of the ceiling fan it brings the warm air down to the floor from the ceiling. This mechanism helps you contain the warm air close to you, and it also helps in reducing the energy bills by as much as 15 percent.

Use draft stoppers on your doors

Draft stoppers installed at the base of the doors prevent the entry of cold wind into the room. So, use these objects to prevent the entry of cold air. However, make sure that the room gets proper ventilation to avoid the accumulation of poisoning carbon monoxide.

Step 5- Light up the candles

Now, it is time to light up the candles. Use a lighter to light every candle individually and cover it to let it radiate heat. Be careful enough to avoid all sorts of fire hazards and mishappenings. Make sure to keep your children and pets away from the flame. Also, make sure to keep a fire extinguisher handy.

Place a large flower pot above the candle

Candles warm up a room only when you create the right heating system using them. To make your candles heat a room effectively, you should place a large plant pot above it. This pot will make heating more effective, as the heat-conducting material will trap the heat. A simple plant pot is manufactured using clay or ceramic, which traps the heat for as long as possible.

To create an effective heating system using flower pots, you’ll need

  • One flower pot measuring 6 inch
  • One flower pot measuring 8 inch
  • One ½ /3½ inch eye hook
  • Three half inch bolts
  • Four half inch washers

The process involves the following steps;

  1. Put the eye hook inside the base hole of the 6 inch pot and lock it with a washer and a bolt.
  2. Next, put the 8 inch flower pot upside down over the eye hook and lock it again using the bold and the washer.
  3. Now put these bots over four tea light candles.
  4. Lastly, let it burn for 15 mins and you’ll be surprised to see how the eye hook radiates the heat inside the room.

Make sure the pot you use has holes, as this hole will allow the carbon dioxide to escape. This is how the candle will get as much oxygen as it needs to burn powerfully.
