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.

Sauna stones sold separately.

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.

Made with care in Estonia

HUUM sauna heatersare made from stainless steel, and they go through a lengthy and carefully monitored manufacturing process that assures the highest quality of each product.
