Slim column heater for small and medium-sized home saunas
Compact form, maximum use of space
The HUUM Cliff 6 kW was designed with ergonomics and space saving in mind. The columnar, slim design allows it to be mounted against a wall or in a corner, leaving more space for benches and comfortable sauna use.
It is the perfect choice for users who want a combination of high quality workmanship, modern design and compact dimensions.
Efficient heating and long-lasting warmth
The specially designed housing of the cooker protects the heaters and optimises the air flow, allowing the desired temperature to be reached up to approx. 25% faster. Thanks to the large number of stones, the cooker gives off heat evenly and over a long period of time, ensuring a comfortable sauna session.
Pouring water over the hot stones generates soft, pleasant steam of high quality, which translates into high thermal comfort and relaxation.
Natural stones and elegant design
One of the most important features of HUUM sauna cookers is the display of natural stones, which form a striking vertical column inside the sauna. The Cliff 6 kW model holds approximately 150 stones with a diameter of 3-5 cm (or a mixture of 3-5 and 5-10 cm).
This form gives the sauna a modern, minimalist yet natural feel, fitting perfectly into popular spa & wellness style arrangements.
Electrical installation and requirements - important information
The HUUM Cliff 6 kW can be supplied either from a three-phase 400 V 3N~ installation or, depending on the installation design, from a single-phase 230 V 1N~ installation. Always consult an electrician for the choice of power supply.
The recommended cross-section of the supply cable and the type of protection (e.g. 3 × 10-16 A overcurrent circuit breaker for 400 V 3N~ or 1 × 25-32 A for 230 V 1N~) should be individually selected by a qualified electrician in accordance with the manufacturer's documentation, standards and local conditions.
Please note:the power cord is not included. 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 - select a set to suit your needs
The HUUM Cliff 6 kW cooker cooperates with external HUUM controllers, which allows you to adjust the functionality to your expectations - from simple time and temperature control to more advanced solutions with the possibility of remote operation (depending on the controller model).
For proper operation it is necessary to use sauna stones - recommended are stones of 3-5 cm or a mixture of 3-5 and 5-10 cm. The stones and the controller are not part of the basic set and must be purchased separately, giving you the opportunity to complete exactly the set you need.
