Installation Considerations for Wood-Burning Heaters
When installing a wood-burning heater in your custom sauna, several factors require careful attention:
Safety Clearances
All wood-burning stoves require specific safety clearances from combustible materials. These typically range from 500mm to 1000mm depending on the model and whether heat shields are used. Custom sauna designs should incorporate these clearances from the planning stage.
Chimney Systems
A proper chimney system is essential for wood-burning heaters. Most require a chimney height of at least 3-5 meters for proper draft. Stainless steel insulated chimney systems are commonly used for their durability and ease of installation.

Ventilation Requirements
Wood-burning heaters need adequate oxygen supply for efficient combustion. Custom saunas should include appropriate ventilation solutions, typically with fresh air intake near the stove and an exhaust vent on the opposite wall.
Floor Protection
Heat-resistant floor protection is necessary under and around the stove. This typically involves a non-combustible base extending at least 400mm in front of the stove door and 100mm on other sides.
