Space, power and setup
Confirm that HUUM Cliff 4 Mini Series 3.5kW suits your sauna room before you order. The manufacturer's sizing for this heater is 106-177 cu ft (3-5 m3); glass, tile and other uninsulated surfaces can increase the effective room volume, so call us if your room has them. Heaters need a clear safety distance to walls and benches (see the manufacturer's manual for the exact figures), and the manufacturer strongly recommends a safety railing around the heater. The heater stands on adjustable legs. Electrical requirements (supply voltage, phase, breaker size and wire gauge) depend on the heater model and your installation, so follow the manufacturer's installation manual and have a licensed electrician confirm them before ordering.
