Know before you buy
This heater is specifically engineered for small home saunas ranging from 106 to 177 cubic feet.
No, the heater requires a separate UKU control system to operate. You will need to purchase a compatible UKU controller to manage your sauna's temperature and timing.
The CLIFF Mini 4 features exceptionally short safety distances, which allows you to install the heater closer to the sauna walls or benches. This is ideal for maximizing usable space in smaller, compact sauna rooms.
The CLIFF Mini 4 includes an internal air duct that promotes efficient airflow, allowing the unit to heat your sauna up to 25% faster than traditional heaters.
Because the design allows for direct contact between the stones and the heating elements, the CLIFF Mini 4 produces consistent, soft heat and abundant steam, providing a traditional sauna experience.
While the unit is wall-mounted and straightforward in design, it requires a 240V, single-phase electrical connection. We strongly recommend having a licensed electrician perform the installation to ensure safety and compliance with local electrical codes.
