Huum Hive Flow
Huum Hive Flow is a modern, highly efficient wood burning sauna heater in its burn technology. Its patent pending furnace creates a complete burn, saving wood and reducing emissions. The high volume of stones stores the heat, so you can let the fire die down and still enjoy plenty of steam and heat from your Hive Flow heater.
This is a robust wood burning sauna heater (only 20,7 in (53 cm) wide) for a mid-to-large sized sauna, holding 150 kg stones. You will need 10 boxes of round stones or 8 boxes of edgy stones.
