Robust, elegant column heater for domestic saunas
Compact form and optimum power
The HUUM Steel 9 kW combines high heating power with a compact, column-shaped design. This makes it ideal for saunas where fast heating and comfortable conditions are expected, but at the same time there is no room for large, massive appliances.
It is a heater for users who are looking for a modern, minimalist design, combined with performance similar to professional solutions.
Efficient heating and comfortable steam
The special design of the HUUM Steel ensures that the heaters are well shielded and that the heat energy is primarily transferred to the stone mass. As a result, the furnace quickly reaches its operating temperature and at the same time provides soft, enveloping steam when pouring water over the stones.
The large number of stones allows the temperature to be maintained for a long time and the heat to be evenly distributed throughout the sauna room.
Natural stones and a steel, modern look
The Steel model is distinguished by the combination of raw steel and natural stone. Approximately 75 stones with a diameter of 3-5 cm fill the entire cooker column, creating a characteristic vertical 'column' of stones that becomes the central visual element of the sauna.
This form fits perfectly into contemporary spa and home sauna arrangements, emphasising their modern, minimalist character.
Electrical installation and requirements - key information
The HUUM Steel 9 kW is a three-phase heater, designed to be supplied from a 400 V 3N~ installation. The correct design and execution of the electrical installation is essential for the safe use and durability of the appliance.
The recommended cross-section of the supply cable (e.g. multicore cable 5 × 2.5 mm² at 400 V 3N~) and the appropriate type of protection (e.g. overcurrent circuit breaker approx. 3 × 16 A) must be selected individually by a qualified electrician, based on the manufacturer's documentation, cable length and installation conditions.
Note:the power supply cable is not included in the scope of supply. The cooker is designed to be permanently connected to a dedicated electrical circuit - it must not be connected to a standard 230 V socket. All connection, configuration and commissioning work must be carried out by a qualified electrician.
Controller and stones - configure the set to your needs
The HUUM Steel 9 kW cooker cooperates with external HUUM controllers, which makes it possible to match the level of functionality to the user's expectations - from simple time and temperature functions to more advanced systems (also with the possibility of control from an app, depending on the controller model).
For proper operation of the cooker, the use of sauna stones is necessary. A quantity of approximately 75 stones with a diameter of 3-5 cm is recommended. Both the stones and the controller are not part of the basic set - they must be purchased separately, which gives you the possibility to fully personalise the sauna equipment.
