Creating a candle space heater is a simple and cost-effective way to add a touch of warmth to your living space during the colder months. This DIY project not only provides a cozy ambiance but also allows you to harness the power of candles to generate a small amount of supplemental heat. In this comprehensive guide, we’ll walk you through the step-by-step process of constructing your own candle space heater, complete with technical details and expert insights to ensure a successful outcome.

Gathering the Necessary Materials

To embark on this DIY project, you’ll need the following materials:

  1. Metal Can or Clay Pot: The foundation of your candle space heater, this container will house the heat-generating components. Choose a sturdy, heat-resistant option, such as a metal can or a clay pot, with a diameter of approximately 6-8 inches.
  2. Fiberglass Sleeves: These sleeves, typically used for insulation, will help to contain and direct the heat generated by the candles.
  3. Nichrome Wire: This heat-resistant wire will serve as the heating element for your candle space heater.
  4. DC Fan: A small DC-powered fan will be used to circulate the warm air generated by the candles.
  5. Cycle Spokes: These sturdy metal rods will be used to support the nichrome wire and create a stable structure for the heater.
  6. Candles: You’ll need a set of tealight or votive candles to provide the heat source for your space heater.
  7. Stone Plate and Bricks: These items will be used to create a sturdy base for the candles.

Preparing the Metal Can or Clay Pot

Begin by thoroughly cleaning the metal can or clay pot to ensure it is free from any debris or sharp edges. If you’re using a clay pot, cover the hole on the smaller pot with a burnt tea light to prevent air from escaping.

Arranging the Candles

Place the candles on the stone plate, using bricks as a sturdy base. Ensure that there is enough space between the candles, approximately 1-2 inches, to allow for proper air circulation.

Assembling the Heater

  1. Nichrome Wire and Cycle Spokes: Wrap the nichrome wire around the cycle spokes, creating a coil-like structure. This will serve as the heating element for your candle space heater.
  2. Attaching the Heating Element: Securely attach the nichrome wire and cycle spoke assembly to the inside of the metal can or clay pot, ensuring a stable and secure fit.
  3. Connecting the DC Fan: Connect the DC fan to the nichrome wire, creating a heat source that will be powered by the candles.

Testing the Heater

Light the candles and allow the heater to heat up. Observe the temperature rise and ensure that the heater is functioning correctly. Monitor the heater closely during operation to ensure safe and efficient performance.

Safety Considerations

It’s important to note that a candle space heater will not produce enough heat to significantly raise the room temperature. However, it can provide a small amount of additional heat and create a cozy atmosphere.

For safety reasons, it’s recommended to keep the candles apart from each other and to monitor the heater while it’s in use. Additionally, using a smart plug with a thermostat and cut-off features can help ensure safe operation.


Creating a candle space heater is a simple and rewarding DIY project that can add a touch of warmth and ambiance to your living space. By following the detailed instructions and safety guidelines outlined in this comprehensive guide, you can build your own candle space heater and enjoy the cozy benefits it provides.
