Created originally to comply with strict German regulations for reducing carbon emissions and improving efficiency in wood-burning stoves, the HIVE Heat now brings this advanced technology to a global market. The HIVE Heat achieves a lower flue gas temperature, transferring more heat into the sauna room and less escaping through the chimney. This design allows optimal heat utilization, offering a superior sauna experience while lessening the environmental impact.  The HUUM HIVE Heat is an advanced sauna stove designed with the environment in mind and boasting a 12kW power rating, making it ideal for sauna rooms sized between 212 to 459 cubic feet. Compared to the HUUM HIVE Wood series, the HIVE Heat features a more innovative airflow system and different materials, including a cast iron stove door focused on burning wood as cleanly and efficiently as possible.
