Harvia Club K10G Club Series 10kW Sauna Heater
The Harvia Club K10G is a 10kW floor-mounted electric sauna heater for rooms from 388 to 600 cubic feet, built for large private saunas and continuous commercial operation in health clubs, hotels, apartment buildings, and day spas. The all-stainless steel body - interior and exterior - with its multi-layer construction is engineered for durability and safe, corrosion-free performance session after session. The open-air stone cage holds 132 lbs of AC3000 stones (3 boxes, 5-10 cm, sold separately) with direct rock-to-element contact for the soft, even löyly that is the hallmark of traditional Finnish sauna bathing. A separate Harvia controller - Xenio CX30 or Fenix FX30, sold separately - is required for operation. Available in 240V/1-phase for residential use and 208V/3-phase for commercial installations. UL tested and listed. ETL certified. Made in Finland by Harvia.
Club Series - super heater for a large group, from morning till night
The Club Series is Harvia's heavy-duty electric heater line - engineered from the ground up for continuous operation and heavy group use. The K10G sits at the entry point of the Club platform, delivering 10kW for rooms from 388 to 600 cubic feet. This is the configuration for sauna installations where a standard residential heater is not built for the demands of the application - facilities that run multiple sessions daily, family saunas that serve a large household and regular guests, and commercial settings where uptime and reliability are requirements rather than nice-to-haves. The Club platform has the same all-stainless steel construction and the same open-cage stone design across all three output ratings (K10G, K12.5G, K15G), so the K10G delivers the full Club experience at the 388-600 cu ft room range.
132 lbs of stones with direct rock-to-element contact
The K10G's stone cage holds 132 lbs (60 kg) of AC3000 stones loaded directly around and against the heating elements. This element positioning is the defining feature of the Club design: heat conducts from element into stone mass first, not into the sauna air directly. The result is filtered, gentle warmth rather than sharp radiant heat from an exposed element surface. The large stone mass stores substantial thermal energy during heat-up, and that stored heat is released steadily throughout the session - consistent temperature without the swings of a lighter stone load. When water is thrown on the stones, the steam is dense and gentle. The minimum stone load of 132 lbs is a safety and performance requirement, not a suggestion - operating with fewer stones is not permitted by the installation manual.
Precise safety distances from the official Harvia specification
The K10G's safety clearances from Harvia's official data: front 3", back 3", left side 3", right side 5", floor 5" (1PH), ceiling minimum room height 6.56 ft, and a minimum ceiling clearance of 4.33 ft above the top of the heater. These clearances define the spatial requirements for the heater within the sauna room and must be observed for safe operation and warranty compliance. All installation work must be performed by a licensed electrician per local code. The Xenio CX30 or Fenix FX30 controller is required and sold separately - the K10G does not operate without a connected external control unit.

Why the Harvia Club K10G stands out
Club Series entry point - 10kW for 388-600 cu ft
The K10G brings the full Club Series platform to the 388-600 cu ft room range. The same all-stainless steel body, open-air stone cage, and direct rock-to-element contact design found across the K12.5G and K15G - built for the same continuous duty cycle and heavy group use - at 10kW for saunas up to 600 cu ft. For large home saunas and smaller commercial applications where 10kW is the right output specification, the K10G is the Club platform entry point without compromise on build quality or performance capability.
132 lbs of stones - dense, lasting löyly
The K10G stone load of 132 lbs (60 kg) is among the largest stone capacities available in an electric heater at this power level. The large stone mass accumulates substantial thermal energy during the heat-up phase and releases it steadily over the course of the session. Steam quality is consistent throughout - repeated rounds of water-pouring produce the same dense, gentle steam because there is enough stored thermal mass to sustain it. The open-cage design ensures air moves freely through the stone bed in all directions, heating the stones evenly and distributing löyly across the full stone surface.
Direct rock-to-element contact - filtered, gentle heat
Heating elements in the K10G sit inside the stone bed rather than beneath it. Stones are packed directly around the elements - heat flows from element to stone mass before reaching the sauna air, filtering out the sharp, dry radiant heat produced by an exposed element. The effect is the soft, comfortable heat of traditional Finnish sauna bathing. This element-in-stone architecture is a deliberate design decision by Harvia for the Club platform - not just for heat quality, but because stone coverage around the elements also protects the elements from direct water contact when throwing löyly.
Multi-layer body - cooler surface, greater safety
The K10G uses a multi-layer body construction where the outer steel shell is separated from the inner heat-conducting components. The exterior surface temperature is kept significantly lower than single-wall designs - important for safety in high-traffic installations where bathers may be near the heater, and for the longevity of the unit during continuous operation. The all-stainless steel interior and exterior resists corrosion from the high-humidity, high-temperature wet sauna environment. IPX4 rating confirms the unit is rated for the splash and steam conditions of normal sauna use.
Xenio CX30 - Wi-Fi control with MyHarvia app
The K10G is compatible with the Xenio CX30 controller (sold separately), which brings Wi-Fi connectivity and MyHarvia app integration. Temperature, session timing, and scheduling can be set and monitored remotely - preheat from a phone before arriving, set weekly schedules, or adjust the session from outside the sauna room. The Fenix FX30 offers the same Wi-Fi and app capability with a different interface style. Both are compatible with the 240V/1PH and 208V/3PH K10G configurations. An optional 24-hour time clock is also available for installations where digital remote control is not required.
UL listed, ETL certified - residential and commercial
The Club K10G holds UL listing and ETL certification for both the 240V/1PH residential and 208V/3PH commercial configurations - the certifications required for installation approval in US and Canadian sauna applications. These certifications are inspected requirements for commercial installation approval in most US and Canadian jurisdictions. All Club Series heaters from Harvia carry these certifications.

Club K10G vs Club K12.5G vs Club K15G - Club Series sizing guide
Club K10G vs Club K12.5G vs Club K15G - selecting the right Club Series size
All three Club Series models share the same stainless steel platform, 132-lb stone requirement, direct rock-to-element design, and UL/ETL certification. The difference is output and room range. Club K10G (this listing): 10kW for 388-600 cu ft - the right choice for large family saunas, smaller hotel or health club rooms, and any application in the 388-600 cu ft range that demands Club-grade durability and continuous-use capability. Club K12.5G: 12.5kW for 494-742 cu ft - the mid-range Club configuration for the overlap zone between large residential and full commercial applications. Club K15G: 15kW for 600-900 cu ft - for the largest commercial and high-volume residential sauna rooms. Choose the K10G when your room is in the 388-600 cu ft range and you want the proven Club platform at the right output for that space. Note: all three models are the same physical dimensions (19.9"W × 16.9"D × 27.5"H) - only the output and circuit requirements change.
