Traditional Sauna Electrical Requirements
Traditional electric heaters are high-load fixed equipment. The heater and control system must be matched to the room and installed to the exact manufacturer documentation.
6 kW is already a substantial load
Harvia currently lists the KIP60W as a 6.0 kW 240V heater for 170–300 ft³. HUUM lists DROP 6 at 6.0 kW, 25 A on 240V with a 30 A breaker in its current US manual.
Controls may be separate
Some heater variants use built-in controls; others require a separate control unit. That changes wiring and parts planning.
Clearance is part of electrical planning
Heater placement, sensor placement and required clearances can determine where conduit and controls can actually go.
Final installation
Electrical requirements vary by exact model, jurisdiction, conductor length, ambient conditions and code. Use this page for planning only; the manufacturer installation manual and a licensed electrician control the final circuit design.

Specifications and installation requirements can change. Confirm the current manual for the exact model before purchase or installation.
