HIVE Heat wood burning stove
Wood burning sauna stoves
HIVE Heat wood burning stove is not only powerful but also environmentally sustainable. Its unique construction supplements the burning process with fresh air from above, providing a powerful flame that ensures all the wood gets burned in the furnace of the sauna stove. This allows the stove to utilize wood gases that commonly escape through the chimney, making it an efficient and eco-friendly choice. The durable furnace door is made of cast iron, and the sauna stove is treated with natural oils. The HIVE Heat wood burning stove meets the strictest German environmental standard BimSchV II, so you can trust that it’s a high-quality and sustainable choice for your sauna.
Outstanding features:
- Model 12 LS has a firebox extension, which enables one to heat the sauna from the adjoining room
- the unique construction ensures the efficiency of the burning process
- treated solely with natural oils
- complies with environmental standard BimSchV II

Sauna heaters that provide mild steam
The amount of metal used in HUUM sauna heaters is very small – this ensures that majority of the heat derives from the stones, and not from the metal. This maximizes the proportion of beneficial negative ions in the air. Negative ions are also called “vitamins of the air”. The amount of negative ions is high, for example, in traditional wood-fired saunas and natural water bodies.
Negative ions and the exceptionally large quantity of sauna rocks are the secret ingredients of the curative, gentle and long-lasting steam of our sauna heaters.
