Harvia Club K15G Club Series 15kW Sauna Heater
The Harvia Club K15G is a 15kW floor-standing electric sauna heater for large rooms from 600 to 989 cubic feet - designed for group use in homes, health clubs, day spas, apartment buildings, hotels, holiday resorts, sports centres, and swimming halls. This listing is for the 240V/1PH configuration (SKU: HRKGU15CU1UL). A Xenio CX45 or Fenix FX45 control unit and 132 lbs of AC3000 sauna stones (3 boxes) are required for operation and sold separately. The Club K15G is the high-output floor-standing tier in Harvia's electric heater lineup - substantially more powerful than the wall-mounted KIP and Spirit series - built for saunas that operate continuously with large groups of bathers from morning through night.
Club Series - built for continuous group use
The Club Series is Harvia's heavy-duty commercial-grade floor heater range. Where the KIP and Spirit series are sized for residential sauna rooms under 300 cubic feet, and the Virta Pro handles 354-1130 cu ft in high-output installations, the Club K15G occupies the 600-989 cu ft range with a purpose-built floor-standing unit designed for continuous operation under load. Harvia explicitly positions it for apartment buildings, hotels, holiday resorts, sports centres, swimming halls, and large family saunas - any installation where the heater needs to perform reliably for groups of bathers over extended daily operating periods. The steel outer shell, stainless steel interior and exterior, and multi-layer construction reflect the durability requirements of commercial-grade continuous use that a residential wall heater does not face.
Multi-layer construction - cooler surface and direct stone-to-element contact
The Club K15G uses two engineering approaches to heat quality and safety. The first is multi-layer construction: multiple thermal layers between the heating core and the outer shell reduce the outer surface temperature during operation - providing a cooler exterior surface for a floor-standing heater in a high-traffic sauna environment where bathers, towels, and equipment pass close to the unit. The second is direct stone-to-element contact: the 132 lbs of AC3000 stones are loaded directly against the heating elements rather than sitting above them in a separate basket. Direct contact filters the intense radiant heat from the elements through the stone mass before it reaches the sauna air, producing a more comfortable, even heat rather than the harsh radiant output of unfiltered electric elements. The result is intense heat that is pleasant to bathe in rather than aggressive.
Xenio CX45 or Fenix FX45 control - required for operation
The Club K15G does not include a control unit and cannot operate without one. A Xenio CX45 or Fenix FX45 control is required and sold separately. The CX45 is Harvia's high-output Xenio control compatible with heaters up to 18kW; the FX45 is the corresponding Fenix touchscreen control with MyHarvia 2 app connectivity. Both are sold at BathingBrands. The 240V/1PH configuration (this listing, HRKGU15CU1UL) requires a 70A dedicated breaker with 4 AWG wire. A licensed electrician is required for all electrical connections. Do not connect to a GFI/GFCI breaker.

⚠️ Xenio CX45 or Fenix FX45 control required - not included. AC3000 stones required - not included. The Club K15G cannot operate without a control unit. A Xenio CX45 or Fenix FX45 must be purchased separately. 132 lbs of AC3000 sauna stones (3 boxes) must also be purchased separately. Note: this heater uses AC3000 stones, not the AC3020 used by most other Harvia heaters - confirm the correct stone model before ordering. A licensed electrician is required. Do not connect to a GFI/GFCI breaker.
ℹ️ 240V/1PH electrical requirements. The 240V/1PH configuration (HRKGU15CU1UL) requires a dedicated 70 Amp breaker and 4 AWG wire. A 208V/3PH configuration is also available for commercial three-phase electrical systems (50A breaker, 8 AWG wire) - contact us if the 3PH configuration is needed. A licensed electrician is required for all electrical connections.

Why the Harvia Club K15G stands out
Heavy-duty continuous group use
The Club K15G is the Harvia electric heater specifically built for high-demand continuous operation - the morning-to-night use pattern of apartment buildings, hotels, sports centres, and health clubs where the heater must perform reliably over extended daily sessions with multiple groups of users. The stainless steel construction, multi-layer outer shell, and direct stone-to-element design are all engineered for the more demanding thermal cycling and use intensity that commercial-grade continuous operation requires compared to residential intermittent use.
Multi-layer construction - cooler exterior
The multi-layer outer shell keeps the exterior surface cooler during operation than single-layer alternatives. In a high-traffic sauna where bathers, towels, and equipment regularly pass near the floor-standing heater, a cooler exterior surface reduces the risk of accidental contact burns. This is a particularly important safety characteristic for the commercial environments the Club K15G is designed for, where the user population is broad and the heater is used continuously rather than occasionally.
Direct stone-to-element contact - filtered even heat
The 132-lb AC3000 stone mass is loaded directly against the heating elements. The stones absorb the initial intense radiant output of the elements and re-radiate it as a softer, more evenly distributed heat into the sauna air. This stone-filtered heat is more comfortable for large groups of bathers at high output levels than unfiltered element radiation. The large stone mass also provides a substantial thermal reservoir for water pouring (loyly) - at 132 lbs, the Club K15G produces generous, sustained steam when water is ladled.
600-989 cu ft range - large group capacity
At 600-989 cu ft, the Club K15G covers sauna rooms large enough to accommodate groups of bathers simultaneously - the room volumes typical of hotel sauna suites, sports centre sauna facilities, and large residential saunas for multi-family or group use. For rooms in this range, wall-mounted heaters are inadequate by both output and stone mass. The Club K15G provides the floor-standing, high-output, high-stone-mass configuration that large room group use demands.
Xenio CX45 or Fenix FX45 - full control capability
The CX45 and FX45 are Harvia's high-output controls compatible with heaters up to 18kW - the correct control tier for the 15kW Club K15G. The Fenix FX45 adds a 4.3" touchscreen, MyHarvia 2 app connectivity, a smart timer that learns the heater's specific heat-up curve, and 3 programmable session presets. The CX45 provides the same high-output control in Harvia's standard Xenio wall-panel format. Both sold separately at BathingBrands.

Club K15G vs Club Series lineup - choosing the right Club output
The Harvia Club Series offers multiple output levels for large sauna rooms. The K15G (this listing) is the 15kW model for 600-989 cu ft. Other Club Series models are available at different output levels for rooms outside this range. All Club Series models share the same floor-standing format, stainless steel construction, multi-layer outer shell, direct stone-to-element contact, and Xenio CX45 / Fenix FX45 control compatibility. The correct Club Series model is determined by the adjusted cubic footage of the specific sauna room - use the Size Your Sauna resource and the Stone Requirement document below to confirm the K15G is appropriately sized before ordering. A licensed electrician is required for all Club Series installations. Do not connect to a GFI/GFCI breaker.
