A homemade wood burning sauna stove can be a rewarding project for those who enjoy the sauna experience. This article provides a technical overview, offering clear and concise information on constructing and safely using a wood burning sauna stove.
Materials and Tools
Before diving into the technical details, gather the necessary materials and tools:
Materials:
Steel Barrel: A steel barrel or thick-walled metal container forms the body of the stove.
Steel Pipe: A length of steel pipe will serve as the stove’s chimney.
Fire Bricks: Fire bricks are used to create the combustion chamber and protect the stove’s walls from extreme heat.
Door and Air Vent: You’ll need a door with an air vent for controlling airflow into the stove.
Stove Grate: A stove grate supports the wood, allowing air to circulate underneath.
Tools:
Angle Grinder: An angle grinder is essential for cutting and shaping metal components.
Welder: A welder is used to join the stove’s components securely.
Drill: You’ll need a drill for creating holes in the steel barrel for the chimney and air vent.
Thermometer: A stove thermometer is useful for monitoring the temperature inside the sauna.
Stove Construction
1. Preparing the Barrel
Cut the steel barrel to the desired height, leaving enough space for the combustion chamber and the chimney. Ensure the top is sealed tightly to prevent smoke from escaping. Create an opening for the door, and attach the door with a hinge for easy access.
2. Building the Combustion Chamber
Inside the barrel, create a firebox with fire bricks. The fire bricks should form a rectangular shape at the bottom, leaving space above for the wood to burn. Ensure the bricks are securely in place.
3. Chimney Installation
Drill a hole in the top of the barrel for the chimney pipe. The chimney should extend above the sauna’s roof to ensure proper ventilation and prevent smoke from entering the sauna.
4. Air Vent
On the door, install an air vent with a control mechanism to regulate the amount of air entering the stove. Adequate airflow is essential for combustion efficiency.
5. Stove Grate
Place a stove grate inside the combustion chamber. This elevates the wood, allowing air to circulate underneath and promote complete combustion.
Safe Operation
Operating a homemade wood burning sauna stove requires careful attention to safety:
Only use seasoned, dry firewood to minimize smoke and creosote production.
Maintain a safe distance between the stove and any flammable materials in the sauna.
Use a stove thermometer to monitor the temperature inside the sauna. Sauna temperatures generally range from 160°F to 195°F (70°C to 90°C).
Ensure proper ventilation in the sauna to prevent a buildup of carbon monoxide. Adequate ventilation also helps maintain a comfortable sauna environment.
Never leave the stove unattended while it’s in operation.
Regularly inspect the stove and chimney for any damage or wear and tear, ensuring they are in good working condition.
Conclusion
Constructing and operating a homemade wood burning sauna stove is a technical endeavor that requires careful planning and attention to detail. By following these steps, you can create a functional and safe sauna heating solution. Remember that safety should always be the top priority when enjoying the benefits of a wood-burning sauna stove.
