Compact classic for your home sauna

Reduced Sauna heater - CUP STJ wall-mounted unit with integrated control unit
Der Helo CUP is an electrically operated Sauna heater for fixed wall mounting. Thanks to its integrated control unit, you do not need an external control unit - all settings are made directly on the stove. A mechanical thermostat precisely regulates the temperature, while a 12-hour timer with up to 9 hours preset time and 3 hours heating time offers maximum flexibility. A temperature limiter with manual reset button ensures safety.
Timeless design - CUP STJ solid wood sauna heater with a clear design language
The matt stainless steel housing of the CUP impresses with its simple yet high-quality appearance. Wall mounting saves valuable space in the interior and supports a quiet feeling of space - especially in compact cabins. The clear lines and functional design make it a discreet eye-catcher in classic and modern saunas.
Suitable for many sizes - CUP home sauna heater for 2-14 m³
Whether a private single cabin or family sauna: the CUP STJ is available in five power levels and can therefore be flexibly adapted to different room sizes. It is ideal for sauna enthusiasts who focus on functionality, safety and durability - without unnecessary extras.
Wall-mounted Sauna heater Cup - application & convenience in everyday life
With its space-saving wall-mounted design, the Helo Cup is ideal for private sauna cabins with limited space. The simple installation is carried out by an authorized specialist company, and thanks to the compatible control systems, the heater can be operated intuitively.
The combination with a remote start function is particularly convenient - for soothing warmth exactly when you need it. Regular cleaning and the occasional restacking of the sauna stones ensure the long-term performance of the appliance.
