K10G Club Series 10kW Stainless Sauna Heater at 208V 3PH

The Harvia K10G is a heavy‑duty sauna heater designed for large private or commercial saunas. Delivering approximately 10 kW of power (9.8 kW nominal) on a 208 V 3‑phase connection, this floor‑standing unit heats rooms from 388 to 600 cubic feet. According to Harvia’s Club manual, KG‑series heaters are purpose‑built to warm large saunas to comfortable bathing temperatures and must not be used for other purposes.

Key Features

• Heavy‑duty floor model: Constructed from stainless steel with long‑life heating elements, the K10G is ideal for continuous operation in health clubs, hotels or spacious residential saunas.

 

• For large saunas: Rated at 10 kW (9.8 kW nominal) to heat rooms 388–600 cu ft quickly and evenly.

 

• External control required: Harvia’s manual specifies that KG‑series heaters require a separate control unit:. Pair the K10G with a Harvia Xenio or Griffin control (e.g., CX30‑U1/U3‑XW or CX45‑U1/U3‑XW) to manage temperature, timer and lighting from outside the sauna.

 

• Large stone capacity: Holds 132 lbs of stones (approx. 3 × 44‑lb boxes) to generate ample steam. Harvia recommends 2–4 inch (4–8 cm) sauna stones arranged loosely so air can flow through the heater.
