Quick Answer
You can heat a quinzhee with a candle, but it requires careful management due to the risk of fire and inadequate heating.
Choosing the Right Candle
To heat a quinzhee with a candle, select a sturdy candle that can withstand wind and cold temperatures. A candle with a diameter of at least 1.5 inches (3.8 cm) and a wax height of 6-8 inches (15-20 cm) will provide sufficient heat. Consider using a candle made from beeswax or a similar wax type that burns more efficiently.
Heating the Quinzhee
Position the candle in the center of the quinzhee, ensuring it is at least 6 inches (15 cm) from the surrounding snow. Light the candle and let it burn for 20-30 minutes to generate heat. Gently move the snow around the candle to distribute the heat evenly. Monitor the temperature and adjust the candle’s position as needed to maintain a consistent heat output.
Safety Precautions
When using a candle to heat a quinzhee, be aware of the potential fire hazard. Keep a bucket of snow or water nearby to extinguish the candle in case of emergency. Monitor the temperature inside the quinzhee closely, and do not leave the candle unattended. A safe temperature range for quinzhee heating is between 40°F (4°C) and 50°F (10°C). If temperatures exceed this range, the quinzhee may become unstable or collapse.
