K10G Club Series 10kW Stainless Sauna Heater at 240V 1PH

The Harvia K10G is a robust, floor‑standing heater engineered to bring commercial‑quality steam to large private or professional saunas. Rated at 10 kW on a 240 V single‑phase circuit, it heats sauna rooms from 388 to 600 cubic feet. Harvia’s official manual notes that KG‑series heaters are specially designed for warming large saunas to comfortable bathing temperatures and should not be used for other purposes.

Key Features

• Heavy‑duty floor model: Durable stainless‑steel construction with long‑life heating elements ensures continuous operation in clubs, hotels or spacious residential saunas.

• Powerful 10 kW output: Delivers ample heat for large sauna rooms (388–600 cu ft); operates on 240 VAC single‑phase with a current draw of 41.7 A and requires dual 30‑amp fuses.

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

• Large stone capacity: Holds 132 lbs of sauna stones (three 44‑lb boxes) to produce generous, consistent steam. For best performance, use 2–4 inch (4–8 cm) solid stones and arrange them loosely to allow airflow.

• Commercial reliability: Backed by a 1‑year limited warranty and ETL certification, this heater is built for demanding daily use.
