HIVE Heat Series Sauna Stove w/ Firebox Extension

The firebox extension on the HUUM HIVE Heat 12 LS allows loading from another rooms so you don't need to store wood in your sauna.

HIVE Heat 12 LS is a highly efficient wood-fired sauna heater for smaller saunas. It has a unique structure where fresh air is conducted into the burning process from above to create a strong flame. This allows the burning to be very clean and makes sure that all the wood gets burned and no wood gas escapes the chimney and goes to waste like it often does with less efficient stoves.

The furnace door is made of cast iron which is incredibly durable and easy to maintain. The cast iron is treated only with natural oils without the use of chemicals.

HIVE Heat complies with strict BimSchV II, the German standard for wood-burning stoves.
