A 9kW heater is a high-power appliance that requires a dedicated 240-volt circuit and must be connected to a 50-amp breaker. This installation is not a DIY project and requires a licensed electrician to ensure everything is hardwired safely and according to local codes for proper and safe operation.
Yes, many 9kW heaters are built to withstand the demands of commercial environments like gyms, spas, and hotels. They are constructed with heavy-duty components for durability and continuous use. If you are setting up a commercial facility, it's often best to look at dedicated large sauna heaters, as they may have specific certifications or warranty requirements for public use.
Stone capacity at this power level is a key feature that defines the sauna experience. A traditional heater may hold 50-60 lbs for a quick, intense heat. However, premium models from brands like HUUM can hold over 550 lbs of stones. This massive stone mass creates an incredibly soft, radiant, and long-lasting steam that is perfect for larger groups.
