Space, power and setup
Measure your doorways, hallways and sauna room before ordering, and check that your room volume falls inside the heater's listed range. Electrical requirements depend on the heater rating and your supply, so have a licensed electrician confirm voltage, breaker and wire size against the manufacturer's installation manual. Keep the clearances to walls, benches and ceiling that the manual lists. A HUUM electric heater needs the UKU control system, which is sold separately, and sauna stones are bought separately. The heat-resistant power cable is not included.
