Elegant design, fast heating and convenient operation
Stainless steel - modern sauna design
The housing of the Harvia Vega BC45 heater is made of stainless steel, which makes the heater look elegant and matches both classic and modern saunas. The material is resistant to corrosion and high temperatures, which translates into a long life of the device.
Built-in control - everything at hand
The control knobs are located on top of the housing, making it easy to adjust the parameters even when using the sauna. You can easily set the temperature and time of the sauna cooker without having to install an additional external controller.
Stones included - better steam and stable temperature
The furnace chamber holds approx. 20 kg of stones, which store heat and allow a pleasant, even temperature throughout the sauna. The right stones provide intense steam and increase bathing comfort. It is recommended to change the stones regularly to maintain the optimal performance of the cooker.
Clever design and low assembly
The cooker is mounted on a separate mounting plate, which speeds up installation. The symmetrical design allows you to choose the side of the electrical connections, and the option of mounting the cooker low on the wall ensures that the heat is distributed evenly - so that a comfortable temperature also prevails on lower benches.
Electrical installation - important information
The Harvia Vega BC45 can be operated in a 400 V 3N (3-phase) installation or - after appropriate selection of fuses - in a 230 V 1-phase installation. Due to the power of the unit, it requires a separate circuit and a properly selected cable cross-section and protection.
Please note: Thepower cable is not included in the scope of supply. Due to the necessity of matching the cable to the specific installation in the facility, we do not sell cables as a set - their selection and connection should be carried out by a qualified electrician/specialist, in accordance with current standards and regulations.
Safety in use
Safety distances from walls, ceiling and floor must be maintained during installation in accordance with the manufacturer's instructions. Correct installation and proper ventilation of the sauna room are crucial for the comfort and safety of users.
